Tariff Wars: Strategies to Prevent Economic Marginalization of Africa

By Dr Stephane Atangana

The global economy is showing signs of structural slowdown. Global inflation is declining (from 6.8% in 2023 to an expected 4.5% in 2025), and medium-term growth has plateaued around 3.1%, a historically low level. Concurrently, « geoeconomic fragmentation » is intensifying—defined by the IMF as a policy-driven reversal of global economic integration. Protectionist measures are multiplying at an unprecedented rate: nearly 3,000 new trade barriers were imposed in 2023, triple the number in 2019. This surge in restrictions jeopardizes the economic architecture that previously lifted 1.5 billion people out of poverty over recent decades. For low- and middle-income African countries, these trends pose a dual challenge: firstly, their economies remain heavily reliant on commodity prices (accounting for approximately 76% of exports in 2023) and struggle with diversification; secondly, they face growing pressures on public finances due to mounting debt. Specifically, external refinancing needs have tripled in a decade, reaching nearly USD 60 billion annually, while debt servicing now consumes over 12% of public revenue on average in sub-Saharan Africa. These constrained fiscal resources severely limit capacities for productive investment and social policies. Thus, the critical question is: How can these vulnerable economies maintain access to international markets while fostering sustainable development?

Impacts and Vulnerabilities from Fragmentation

Geoeconomic fragmentation is already significantly impacting African trade and finance. Africa’s total merchandise trade declined by approximately 6% in 2023 due to supply chain disruptions and rising global protectionism. Indeed, new tariff surcharges announced by the US administration in April 2025 are expected to exacerbate this decline. IMF macroeconomic simulations indicate that substantial tariff hikes could reduce sub-Saharan African GDP by 0.2 to 0.4 percentage points by 2027 through decreased exports and higher input costs.

This contraction primarily affects commodity-importing countries already vulnerable to global price volatility. Conversely, intra-African trade grew by 7.2%, reaching USD 192 billion (15% of the continent’s total trade). This increase indicates regional resilience, partly due to the gradual implementation of the African Continental Free Trade Area (AfCFTA). However, this share remains low compared to other trading blocs (around 25% in ASEAN), highlighting the untapped potential of African economic integration.

Foreign Direct Investment (FDI) into Africa also declined, totaling about USD 53 billion in 2023, a 3% decrease compared to the previous year. This drop resulted from fewer investments in extractive industries and heightened perceptions of risk. Consequently, most African countries are rated « speculative » by credit agencies, significantly raising their international borrowing costs. For instance, Ghana’s downgraded credit rating sharply increased its borrowing rates, intensifying fiscal pressures.

These factors collectively heighten the vulnerability of African countries to external shocks. The IMF notes that recent surges in food prices have plunged dozens of low-income countries into severe food crises. A pessimistic scenario involving conflict and trade disruptions could divert the Sahel’s regional GDP trajectory by nearly 20%. The transmission channels are manifold: trade barriers immediately reduce export revenues; rising international interest rates dampen productive investment; and food price shocks deepen fiscal deficits and social instability. In response, many multinational firms are reconfiguring value chains towards politically safer countries, diverting vital FDI and technologies needed for Africa’s economic diversification.

International Lessons: Diversification, Integration, and Strategic Reserves

Several regional experiences provide best practices relevant to Africa:

• Industrial Diversification: Vietnam exemplifies successful export-oriented industrial strategy. Following Đổi Mới reforms and the creation of special economic zones, Vietnam became a significant manufacturing hub (electronics, textiles), deeply integrated into global value chains. By 2021, exports of goods and services represented approximately 93% of GDP, enhancing economic resilience. Vietnam’s experience shows how coherent industrial policy combining trade openness and investor incentives can transform an agricultural economy into a diversified export platform.
• Regional Integration: Regional blocs have buffered external shocks by diversifying demand and smoothing intra-zone trade. MERCOSUR illustrates this clearly: despite a 4% decline in overall exports in 2023, trade among member states increased by 4.2%,driven by manufacturing dynamism and sectoral solidarity (such as mitigating drought impacts). Regional integration thus broadens markets and strengthens commercial resilience by diversifying demand sources, especially during global market shocks.
• Strategic Food Reserves: Several Asian and Latin American countries developed food reserves to mitigate price volatility risks. Following the 2007-2008 global food crisis, ASEAN+3 established an emergency rice reserve (APTERR) to stabilize supply during shortages. The FAO noted countries with substantial food reserves better managed price shocks post-2008. Such precautionary policies enhance food security and reduce import dependence during crises, serving as exemplary models for African agricultural strategies.

Policy Recommendations for Africa

To confront global geoeconomic fragmentation, African low- and middle-income countries should adopt a two-pronged strategy:

1. Strengthen Regional Integration and Market Diversification: Fully leveraging AfCFTA is essential to reduce external shock vulnerability. The goal is increasing intra-African trade significantly above 25% by 2030 (from approximately 15–16% currently), broadening African exporters’ markets. Achieving this requires harmonizing technical and sanitary standards, streamlining transport corridors (road, rail, ports), and simplifying border procedures. Facilitating intra-African trade can create a critical-size regional market, amplify industrialization opportunities, and provide a safety net against global market disruptions.
2. Secure Sustainable and Green Long-term Financing: Guaranteeing developmental resources despite global uncertainties is crucial. Improving governance, transparency, and macroeconomic stability will attract and retain productive FDI, particularly in future-oriented sectors (renewable energy, local commodity transformation, green technologies). Simultaneously, significantly mobilizing local savings through deeper domestic financial markets is vital. Developing local-currency bond markets can enable African states and businesses to finance long-term infrastructure projects, reducing foreign exchange exposure. Enhancing financial inclusion and diversifying funding instruments are key strategies to solidify domestic financial capacity.

Conclusion

The surge in global trade barriers and rival economic blocs marks the resurgence of « tariff wars, » potentially marginalizing Africa’s most vulnerable economies. Our analysis highlights three core findings: a marked decline in African exports due to global protectionism, reduced FDI inflows and increasingly expensive external financing, and structural vulnerabilities from commodity dependence and debt. Despite these challenges, Africa holds promising assets: intra-African trade momentum demonstrates AfCFTA’s potential as a powerful buffer, while international experiences provide proven templates. Two operational priorities emerge: (1) transforming AfCFTA into a robust continental shield by harmonizing standards and procedures, and (2) securing stable financing by improving governance to attract productive FDI and mobilizing local savings. Immediate action can convert global economic retreat into regional momentum, whereas hesitation risks sustained marginalization. African policymakers possess tools—integration, diversification, strategic reserves, and strengthened financial markets—to maintain Africa « in the game » and steer the continent towards autonomous, diversified, resilient growth.
