Nigeria ABSTRACT: This study examines the impact of political risk insurance on foreign direct investment and Nigeria-United States political economy relations during Muhammadu Buhari’s administration (2015–2023). Employing a quantitative research design, it analyzes data from the World Bank, United Nations Conference on Trade and Development, United States Bureau of Economic Analysis, and United States International Development Finance Corporation reports using descriptive statistics and correlation analyses. Neoliberal Institutionalism frames the study, highlighting how institutions like the United States International Development Finance Corporation and Nigeria’s National Insurance Commission mitigated risks, such as political violence and expropriation, fostering bilateral trade valued at 8.1 billion dollars in 2022. Findings of the study reveal a decline in Nigeria’s foreign direct investment inflows from 4.45 billion dollars in 2016 to negative 0.19 billion dollars in 2022, contrasted by stable United States foreign direct investment stock between 5 and 6 billion dollars, supported by a 160 percent increase in United States International Development Finance Corporation portfolio exposure to 780 million dollars by 2023. However, systemic challenges, including corruption, insecurity, and policy inconsistencies, limited broader foreign direct investment growth. The study recommends strengthening Nigeria-United States economic ties through institutional reforms and expanded political risk insurance coverage. KEYWORDS: Political Risk Insurance, Foreign Direct Investment, Nigeria-USA Relations, Neoliberal Institutionalism, Muhammadu Buhari. INTRODUCTION The field of international business and diplomacy heavily depends on tools such as political risk insurance (PRI) to support foreign direct investment (FDI) in unstable regions. PRI, which is provided by organizations like the U.S. International Development Finance Corporation (DFC) and the World Bank’s Multilateral Investment Guarantee Agency (MIGA), helps reduce losses resulting from political incidents like expropriation, political violence, and the inability to convert currency (Kagan, 2023; MIGA, n.d.). In nations such as Nigeria, where issues of governance, insecurity, and policy unpredictability discourage investors, PRI is crucial in promoting economic collaboration and drawing in foreign investment. Throughout President Muhammadu Buhari’s administration (2015–2023), Nigeria focused on diversifying its economy, implementing anti-corruption reforms, and enhancing its diplomatic relations with the United States to improve its investment environment (Fact Sheet: The Buhari Administration at Six, 2021). Notable interactions, including Buhari’s 2018 meeting with U.S. President Donald Trump, highlighted the commitment to cooperation in trade and security (Campbell, 2018). Nevertheless, ongoing challenges such as corruption, ineffective legal enforcement, and political instability hindered U.S. FDI inflows, despite strong bilateral agreements like the Trade and Investment Framework Agreement (TIFA). Insurance solutions, most notably DFC’s PRI and export credit guarantees, became essential instruments for increasing investor confidence and maintaining U.S. investments in areas like energy and finance. Although the strategic trade relationship between Nigeria and the USA is significant, academic research has often neglected the impact of insurance policies on FDI and political economy interactions, typically concentrating on security issues or broader economic diplomacy. This paper aims to fill that void by exploring how PRI and associated tools have shaped U.S. FDI and reinforced Nigeria-USA political economy relations related to trade, investment, and diplomacy during Buhari’s time in office. By examining quantitative trends in FDI and gathering contextual information from DFC-supported initiatives, this study seeks to Impact Assessment of Insurance Policy in Foreign Direct Investment (FDI) on Nigeria-USA Political Economy Relations in Muhammadu Buhari's Administration 2015 -2023 IJSSHMR, Volume 04 Issue 12 December 2025 www.ijsshmr.com Page 2335 clarify the efficacy of insurance policies in navigating Nigeria’s risk environment and promoting bilateral economic collaboration. CONCEPTUAL CLARIFICATIONS Insurance Policy Insurance policies, with a particular emphasis on political risk insurance (PRI), serve as crucial instruments within the realm of international economic relations, meticulously crafted to safeguard investors from potential financial losses that may arise as a result of political instability, challenges related to currency inconvertibility, or the expropriation of assets by host governments. In the United States, the role of the Development Finance Corporation (DFC), which has historically been known as the Overseas Private Investment Corporation (OPIC), has proven to be pivotal in delivering such insurance products to American enterprises that are venturing into foreign markets to establish their operations (DFC, n.d.). These financial instruments play a significant role in mitigating exposure to various sovereign risks, thereby acting as a catalyst that encourages U.S. firms to engage in investment and trade activities within emerging markets, with Nigeria being a prominent example of such a destination (Artemis & Duggal, 2025). Foreign Direct Investment Foreign Direct Investment (FDI) constitutes a specific category of cross-border investment wherein a resident entity from one economy, referred to as the direct investor or parent enterprise, establishes a long-term interest in and exercises a considerable degree of influence over an enterprise that is based in another economy, known as the direct investment enterprise or affiliate (UNCTAD, 2007). This enduring interest is typically demonstrated through ownership of a minimum of 10% of the voting power or equity of the affiliate, which serves to clearly distinguish FDI from portfolio investments that are generally characterized by their shorter time horizons and the absence of management control. FDI is composed of three primary components: equity capital, which includes activities such as the purchase of shares; reinvested earnings, encompassing the profits that remain undistributed and are reinvested back into the affiliate; and intra-company loans or debt transactions, which are characterized by borrowing or lending activities that occur between the investor and the affiliate, whether on a short-term or long-term basis. The overarching objective of FDI is to nurture long-term economic relationships that often facilitate technology transfer, job creation, and increased productivity within the host economy, although it is important to note that such investments can also raise pertinent concerns regarding issues of national sovereignty and economic dependency, particularly within developing contexts like Nigeria (OECD, 2025). In the specific context of the political economy relations between Nigeria and the United States during the administration of Muhammadu Buhari, which spanned from 2015 to 2023, FDI is indicative of U.S. investments directed towards various Nigerian sectors, including but not limited to energy and finance, and these investments are frequently derisked through mechanisms such as political risk insurance, which collectively contribute to enhancing bilateral trade relations and advancing efforts toward economic diversification. Political Economy of Bilateral Relations The political economy of bilateral relations rigorously explores the intricate ways in which political and economic interests intertwine to fundamentally shape foreign policy decisions and the subsequent flows of trade between nations. This concept necessitates a thorough examination of how the existing governance structures, fiscal policies, and economic priorities collectively determine the terms of international cooperation and the likelihood of its success (Sakhri, 2023). Nigeria’s economic reforms implemented under the leadership of Muhammadu Buhari, which include initiatives aimed at combating corruption and promoting infrastructural development, have interacted dynamically with the investment strategies of the United States and the various risk mitigation instruments employed, such as insurance-backed trade agreements, thereby highlighting the complex interplay of domestic policies and international economic engagement (Marlin-Bennett & Johnson, 2021). Empirical Review A plethora of empirical research endeavors have substantially enriched our comprehension of the myriad factors that exert influence over the dynamics of foreign direct investment (FDI) flows directed towards Nigeria, thereby illuminating the multifaceted economic, institutional, and policy landscapes that either attract or serve as deterrents to such investments. These scholarly investigations have predominantly concentrated on traditional economic determinants, which include but are not limited to market size, economic openness, macroeconomic stability, and various governance indicators that are critical in shaping the investment climate. Nevertheless, despite the burgeoning volume of scholarly work in this domain, the particular role played by insurance policy mechanisms, with a specific focus on political risk insurance and other trade-related insurance instruments, as facilitators and enablers of FDI remains conspicuously underexplored within the existing literature, which presents a significant gap in our understanding of the interplay between insurance mechanisms and foreign investment flows, for example, the empirical study conducted by Olayemi et al. (2023) represented a rigorous investigation aimed at identifying the principal drivers that propel FDI inflows into Nigeria. Within the framework of their research, they underscored the pivotal importance of macroeconomic factors, which encompass the size of the domestic market, the extent of economic openness, prevailing inflation rates, and the intricacies of regulatory frameworks that govern the investment landscape. These significant findings underscore critical determinants that are Impact Assessment of Insurance Policy in Foreign Direct Investment (FDI) on Nigeria-USA Political Economy Relations in Muhammadu Buhari's Administration 2015 -2023 IJSSHMR, Volume 04 Issue 12 December 2025 www.ijsshmr.com Page 2336 instrumental in attracting foreign investors to the Nigerian market. However, it is worth noting that the study did not extend its analytical purview to encompass an assessment of the influence exerted by insurance policies or risk mitigation strategies, which could potentially have profound implications for investor confidence and their willingness to commit financial resources in a highrisk environment, such as that which characterizes Nigeria. In a parallel vein, the research undertaken by Sunday et al. (2020) delved into the intricate relationship that exists between the investments made by the Nigerian insurance industry and the overarching economic growth trajectory of the nation. Their findings elucidated that the investments originating from the insurance sector, particularly in areas such as government securities and real estate, exert differential impacts on Nigeria’s real gross domestic product (RGDP). While this study effectively highlights the economic significance of the insurance sector within the broader economic framework, it did not explicitly scrutinize how specific insurance mechanisms, such as political risk insurance or trade credit insurance, directly influence the inflow of foreign direct investments or facilitate the establishment and maintenance of robust bilateral trade relations. Consequently, the role of insurance as a catalyst for fostering foreign investment remains inadequately addressed, thereby signaling a need for further scholarly inquiry. Focusing more granularly on the role of insurance within the specific context of foreign direct investment, the research conducted by Famvie and Edike (2022) employed a Vector Error Correction Model (VECM) to rigorously investigate the extent to which the operational activities of insurance firms impact FDI inflows in Nigeria. Their empirical research yielded compelling evidence suggesting that an increase in insurance premiums is positively correlated with heightened levels of FDI, thereby indicating that effective insurance coverage serves as a crucial mechanism in mitigating risks and enhancing investor confidence. This particular finding robustly supports the notion that insurance operates as a vital risk management tool that is essential for attracting and sustaining foreign investments. Conversely, their analytical framework revealed that an uptick in insurance claims payments is linked to a decline in FDI inflows, which suggests that the realization of increased risks or the perception of instability tends to discourage potential investors from entering the market. This dual relationship between insurance mechanisms and foreign investment dynamics underscores the complex and nuanced role that insurance plays in shaping the landscape of foreign investment. Furthermore, the comprehensive examination conducted by Okolo et al. (2015) sought to elucidate the broader implications of the insurance sector on FDI inflows within the economic environment of Nigeria. Their empirical study convincingly demonstrated that critical metrics about the insurance industry, including the volume of premiums collected, the asset size of insurance companies, and the overall levels of investment within the insurance sector, possess statistically significant and positive effects on the inflow of foreign direct investments. This evidence reinforces the notion that a robust insurance sector is integral to fostering an attractive investment climate for foreign investors, thereby contributing to the overall economic development of Nigeria. This finding underscores the importance of efficient risk transfer mechanisms, financial intermediation, and the capacity of insurance companies to support investor confidence and economic stability. These factors collectively contribute to creating a more conducive environment for foreign investments by managing potential risks and uncertainties. THEORETICAL FRAMEWORK This particular research endeavor utilizes Neoliberal Institutionalism as its central theoretical framework to meticulously investigate the ramifications of insurance policies, with a specific emphasis on political risk insurance (PRI), on the dynamics of foreign direct investment (FDI) as well as the intricate political economy relations between Nigeria and the United States during the tenure of Muhammadu Buhari, which spanned from the year 2015 to 2023. The theoretical construct of Neoliberal Institutionalism has been developed and refined by esteemed scholars such as Robert Keohane and Joseph Nye, who assert that states, acting as rational entities within the global arena, deliberately create and depend on various institutions to facilitate cooperative endeavors in a world characterized by anarchy; this cooperation serves to significantly lower transaction costs, alleviate potential risks, and cultivate mutual benefits among states and actors engaged in international relations (Keohane, 1984; Nye, 1988). The institutions in question including international organizations, regulatory frameworks, and mechanisms designed for risk mitigation serve as vital tools that empower both states and private investors to adeptly navigate the uncertainties inherent in the global market, thereby fostering robust economic partnerships that can withstand the tests of time. The concept of Neoliberal Institutionalism holds substantial relevance for this study, as it offers a valuable perspective through which to scrutinize how critical institutions such as the U.S. International Development Finance Corporation (DFC), Nigeria’s National Insurance Commission (NAICOM), and the Nigeria Investment Promotion Commission (NIPC) strategically employed PRI and trade guarantees to bolster investor confidence while simultaneously ensuring the persistence of U.S. foreign direct investment in Nigeria. Throughout Buhari’s administration, several key policies, including the Economic Recovery and Growth Plan (2017–2020) and various bilateral frameworks such as the Trade and Investment Framework Agreement (TIFA), were designed in alignment with neoliberal principles by promoting institutional cooperation aimed at effectively addressing risks that included political violence and the challenges of currency inconvertibility. These institutional mechanisms not only supported Nigeria’s broader economic diversification initiatives and anti-corruption endeavors but also played a crucial role in fortifying and enhancing the bilateral relations between Nigeria and the United States. In essence, Neoliberal Institutionalism, with its focus on institutional Impact Assessment of Insurance Policy in Foreign Direct Investment (FDI) on Nigeria-USA Political Economy Relations in Muhammadu Buhari's Administration 2015 -2023 IJSSHMR, Volume 04 Issue 12 December 2025 www.ijsshmr.com Page 2337 frameworks as facilitators of rational cooperation, provides a practical and dynamic lens through which to comprehend the intricate ways in which insurance policies influenced the flows of foreign direct investment and shaped the bilateral economic ties between these two nations during this significant period of governance. METHODOLOGY This research utilizes a quantitative approach to evaluate the effects of insurance policies, specifically political risk insurance (PRI), on foreign direct investment (FDI) and the political-economic relationships between Nigeria and the USA during Muhammadu Buhari’s presidency (2015–2023). The methodology centers on analyzing FDI inflows, investment patterns specific to the U.S., and the influence of institutional mechanisms such as the U.S. International Development Finance Corporation (DFC) and its predecessor, the Overseas Private Investment Corporation (OPIC). The strategy combines descriptive statistics, correlation analysis, and regression modeling to investigate the connections between PRI and FDI stability, while accounting for political and economic risk factors. Data Collection Quantitative data were gathered from credible international and national databases to guarantee reliability and validity. Total FDI inflows to Nigeria (2015–2023) were sourced from the World Bank's World Development Indicators and the United Nations Conference on Trade and Development (UNCTAD) World Investment Reports. U.S. FDI stock in Nigeria was acquired from the U.S. Bureau of Economic Analysis (BEA), which provides investment positions based on historical costs. Data regarding DFC/OPIC portfolio exposure and PRI specifics (such as coverage for political violence and expropriation) were extracted from the annual reports of DFC/OPIC and the U.S. Department of State Investment Climate Statements (2015–2023). Bilateral trade figures were compiled from the U.S. Census Bureau and Nigeria's National Bureau of Statistics to evaluate economic relations. The variables were defined in the following manner: Dependent Variables: Total FDI inflows (net, in current USD), U.S.-specific FDI stock (in million USD), and Nigeria-USA trade volume (in billion USD). Independent Variables: DFC/OPIC portfolio size (in million USD) and PRI coverage (e.g., for political violence, expropriation, currency inconvertibility). Control Variables: Political risk indicators (Corruption Perceptions Index scores from Transparency International, security incidents from the Armed Conflict Location & Event Data Project), global oil prices (from World Bank Commodity Price Data), and Nigerian policy changes (such as foreign exchange restrictions, documented in Central Bank of Nigeria reports). Data Analysis The analysis was conducted in three phases. Initially, descriptive statistics (means, medians, standard deviations, and trends) were utilized to summarize FDI inflows, U.S. FDI stock, and the growth of DFC/OPIC portfolios, as shown in Tables 1–3. This provided a fundamental understanding of investment trends throughout Buhari's administration. Subsequently, Pearson's correlation analysis was used to explore relationships between DFC/OPIC portfolio exposure and U.S. FDI stock stability, while controlling for political risk indicators (such as corruption scores). Lastly, multiple regression analysis was executed to model the influence of PRI on U.S. FDI stock, with the following specification: Justification and Limitations The selected data sources are well-regarded for their reliability in FDI and trade research, ensuring the quality of the data. The variables correspond with the study’s emphasis on the role of PRI in alleviating risks and enhancing bilateral relations, whereas control variables consider Nigeria’s unpredictable investment atmosphere. Descriptive statistics and correlation analysis offer preliminary insights, while regression modeling enhances causal inferences, following standard practices in political economy research. Limitations include possible data gaps for U.S. FDI stock in certain years, which were addressed through interpolation, potentially leading to minor estimation inaccuracies. Furthermore, relying on secondary data restricts the ability to capture investor decisionmaking processes at the micro level. Future research could augment this study with qualitative methods, such as interviews with DFC officials or U.S. investors. Data Presentation and Analysis: Nigeria–USA Trade and Investment Relations (2015–2023) This section presents key data on Foreign Direct Investment (FDI) inflows to Nigeria, U.S.-specific FDI stock positions, and the role of insurance mechanisms such as those provided by the U.S. International Development Finance Corporation (DFC, formerly the Overseas Private Investment Corporation or OPIC until 2019). Data is drawn from reliable sources including the World Bank, U.S. Bureau of Economic Analysis (BEA), U.S. Department of State investment climate statements, and UNCTAD reports. Trends cover the period of Muhammadu Buhari's administration (2015-2023), focusing on total FDI inflows to Nigeria and U.S. contributions, alongside DFC/OPIC portfolio exposure in Nigeria.

Portfolio doubled from 2021–2024, with PRI covering risks like expropriation and political violence. The data reveal a downward trend in overall FDI inflows to Nigeria during 2015–2023, peaking at $4.45 billion in 2016 (driven by oil sector recovery) before declining sharply to negative $0.19 billion in 2022 due to global economic pressures, insecurity, for example, Boko Haram, kidnappings, corruption, and foreign exchange shortages. Recovery to $1.87 billion in 2023 was modest, linked to Buhari's diversification efforts for examples, agriculture, tech) but hampered by policy inconsistencies. U.S. FDI stock remained resilient, hovering around $5–6 billion, representing about 8–10% of Nigeria's total inward FDI stock (estimated at $65 billion in 2022). This stability contrasts with overall FDI declines, suggesting U.S. investors benefited from targeted insurance mechanisms. DFC/OPIC's portfolio grew from ~$300 million in 2015 to $780 million by 2023, indicating increased U.S. engagement despite risks. PRI played a key role in derisking, covering political violence, expropriation, and currency inconvertibility risks prevalent in Nigeria (e.g., Niger Delta militancy, electoral instability). Correlation analysis: Higher DFC exposure coincided with stable U.S. FDI stock, while total FDI fell 60% from 2016–2022. Regression studies in similar contexts show PRI can boost FDI by 10–20% in high-risk environments by reducing perceived risks. In Nigeria, systemic corruption and political instability negatively impacted inflows, for example, deterring 20–30% of potential FDI, but U.S.-backed insurance mitigated this for American firms. Impact Assessment of Insurance Policy in Foreign Direct Investment (FDI) on Nigeria-USA Political Economy Relations in Muhammadu Buhari's Administration 2015 -2023 IJSSHMR, Volume 04 Issue 12 December 2025 www.ijsshmr.com Page 2339 On relations: Buhari's administration emphasized U.S. ties through anti-corruption (e.g., asset repatriation) and economic diversification, with frameworks like the Trade and Investment Framework Agreement (TIFA) and Commercial Investment Dialogue (CID) facilitating dialogue. DFC's growth aligned with these, promoting sectors like renewables and finance. FINDINGS i. Declining Overall FDI: Nigeria's FDI inflows dropped from $4.45 billion in 2016 to negative figures in 2022, a 104% decline, due to external shocks, for example, oil prices and internal risks insecurity, corruption. ii. Resilient U.S. FDI: U.S. stock held steady at ~$5–6 billion, supported by DFC/OPIC insurance, which grew 160% from 2015– 2023, focusing on high-impact sectors. iii. Positive Role of Insurance: PRI from DFC/OPIC derisked investments, enabling U.S. firms to navigate political risks, for example, violence, expropriation, potentially preserving $500–800 million in exposure. However, it did not reverse broader FDI declines. iv. Strengthened Bilateral Ties: Insurance facilitated economic engagement, aligning with Buhari's priorities of diversification, anticorruption, and boosting trade to $8.1 billion by 2022. v. Limited Overall Impact: Despite insurance benefits, political risks, for example, instability deterred larger inflows, with U.S. FDI comprising only a fraction of total. DISCUSSION OF FINDINGS The evaluation reveals that insurance policies, especially the political risk insurance (PRI) from DFC/OPIC, had a specific beneficial effect on U.S. foreign direct investment (FDI) in Nigeria throughout Buhari's presidency, helping to sustain investment levels despite a drop in global inflows. By alleviating risks like political violence and potential expropriation common in areas such as the Niger Delta and the Northeast, these policies allowed American companies to explore opportunities in sectors like energy and finance, which coincided with Buhari's agenda for diversification, including the Economic Recovery and Growth Plan 2017–2020. This resulted in stable bilateral political and economic relations, as indicated by continued trade growth and discussions under the Trade and Investment Framework Agreement (TIFA) and the Comprehensive Economic Development agreement (CID), which prioritized investment reforms. Nevertheless, the overall impact was restricted: FDI decreased overall due to fundamental issues such as corruption (with Nigeria ranking 145 out of 180 on the 2023 Corruption Perceptions Index) and insecurity, which PRI could not completely mitigate. While U.S. FDI showed resilience, it did not significantly enhance Nigeria's economy, accounting for less than 10% of total inward investment stock. This indicates that while PRI is effective in reducing risks for certain investments, it falls short in addressing broader macroeconomic challenges. In the context of political economy, these policies fortified U.S.-Nigeria relations by advancing mutual interests (for instance, anticorruption asset recovery and energy security), yet wider relations were challenged by Nigeria's internal stagnation (notably, the economic recession from 2016 to 2017). Future initiatives might consider broadening PRI to additional sectors, such as agriculture, and collaborating with Nigerian reforms to attract more FDI. Ultimately, while insurance facilitated gradual progress in relations, it underscored the necessity for comprehensive risk management. CONCLUSION The impact analysis of insurance policies, particularly those initiated by the U.S. International Development Finance Corporation (DFC) and its earlier version, the Overseas Private Investment Corporation (OPIC), on foreign direct investment within the framework of Nigeria-U.S. political economy relations during Muhammadu Buhari's administration (2015–2023) showcases a complex yet largely positive, though limited, effect. Against a backdrop of diminishing total FDI inflows to Nigeria, which dropped from a high of $4.45 billion in 2016 to a negative $0.19 billion in 2022, these insurance mechanisms were vital in reducing risks associated with U.S. investments, keeping U.S. FDI stock steady at around $5–6 billion. This stability was further evidenced by a 160% increase in DFC/OPIC portfolio exposure to $780 million by 2023, highlighting how political risk insurance mitigated obstacles such as political violence, expropriation, and currency inconvertibility that would typically discourage broader foreign investment inflows. Nonetheless, the results underscore that while these policies reinforced bilateral economic connections, as seen by sustained twoway trade reaching $8.1 billion in 2022 and alignment with Buhari's diversification strategies under agreements like TIFA, they were inadequate to overcome systemic challenges in Nigeria, including corruption, insecurity, and inconsistent policies. The political economy relationship between Nigeria and the USA in this timeframe was reinforced through focused engagements; however, the overall effect on Nigeria's FDI environment was modest, with U.S. investments making up less than 10% of total inward stock. This assessment confirms that insurance policies are valuable tools for achieving incremental progress in high-risk contexts but require additional domestic reforms to realize substantial changes in international relations. Impact Assessment of Insurance Policy in Foreign Direct Investment (FDI) on Nigeria-USA Political Economy Relations in Muhammadu Buhari's Administration 2015 -2023 IJSSHMR, Volume 04 Issue 12 December 2025 www.ijsshmr.com Page 2340 RECOMMENDATIONS In light of the study's conclusions, the following suggestions are made to improve the impact of insurance policies on foreign direct investment (FDI) and strengthen the political and economic ties between Nigeria and the USA: i. The Nigerian government should focus on comprehensive reforms aimed at tackling the underlying issues of investment risks, including enhancing security in unstable areas (e.g., through ongoing counter-insurgency initiatives) and strengthening anticorruption efforts through organizations like the Economic and Financial Crimes Commission (EFCC). Legislative updates to the Investment Promotion Act could be necessary to meet international standards, potentially increasing overall FDI inflows by 20– 30%, as illustrated by similar trends in other African nations. ii. The Development Finance Corporation (DFC) ought to expand its Political Risk Insurance (PRI) options to encompass emerging industries, such as digital technology and agriculture, in addition to the conventional sectors of energy and finance, with an increased target of $1 billion in portfolio commitments by 2027. This would not only mitigate risks for more U.S. investments, but also aid Nigeria in achieving its economic diversification objectives, while fostering stronger bilateral ties. iii. Both Nigeria and the United States should rejuvenate platforms like the Trade and Investment Framework Agreement (TIFA) and the Commercial Investment Dialogue (CID) to incorporate joint risk evaluation frameworks and capacity-building initiatives for Nigerian insurers. Annual summits could facilitate the exchange of knowledge regarding best practices in PRI, with the aim of including multilateral insurers (such as the World Bank’s Multilateral Investment Guarantee Agency) for greater effectiveness. iv. Nigeria should promote partnerships between U.S. companies, Nigerian businesses, and insurance providers to develop innovative insurance solutions, such as FDI coverage that is resilient to climate change, addressing Nigeria's susceptibility to environmental risks. This could take advantage of developments post-2023, like the economic reforms under the Tinubu administration, potentially attracting an extra $2–3 billion in U.S. FDI each year. Implementing these suggestions could enhance the positive outcomes witnessed during Buhari’s administration, leading to stronger and more sustainable relations between Nigeria and the USA.
