How Tariffs Disproportionately Hurt Small Economies
Key Takeaways
- US average tariff rates rose from 2.8% to over 20% during 2025, affecting 57 trading partners
- Small economies face the steepest rates: Myanmar (49%), Laos (38%), Bangladesh (37%), Cambodia (35%)
- WTO projects world merchandise trade declining 0.2% in 2025, nearly 3 percentage points below the low-tariff baseline
- Bangladesh could lose $3.3 billion in annual US exports by 2029 under current tariff levels
- Supply chains are reconfiguring in real time, with Vietnamese exports redirecting from the US toward MENA, the EU, and Korea
What Are Reciprocal Tariffs?
Reciprocal tariffs are import duties that one country imposes to match or counter the tariff rates charged by a trading partner. In 2025, the United States applied reciprocal tariffs to 57 countries at rates calculated to offset perceived trade imbalances - resulting in duties ranging from 10% to 49% depending on the target economy. For small, export-dependent nations, these rates can effectively price entire industries out of the US market.
When this article was first published in November 2024, US tariff escalation was a risk scenario. By mid-2025, it became reality. The resurgence of protectionist measures - particularly the sweeping “reciprocal tariffs” imposed on 57 trading partners - has confirmed the central thesis of this analysis: while large economies absorb tariff shocks through diversified domestic markets and bargaining power, smaller economies bear disproportionate damage with far fewer tools to respond.
This update incorporates the actual tariff data, UNCTAD assessments, and WTO trade projections from the first year of the new tariff regime.
What Actually Happened: The 2025 Tariff Escalation
US tariff rates increased from an average of 2.8% before 2025 to over 20% by September 2025 - the largest single-year increase in modern trade history. UNCTAD described it as a “tectonic shift in tariff policy.” The WTO projected that world merchandise trade would decline by 0.2% in 2025, nearly three percentage points lower than what would have been expected under a low-tariff baseline scenario.

Among the ten most affected countries globally, three are Least Developed Countries (LDCs): Myanmar, Laos, and Bangladesh. These are nations where tariff exposure is not an inconvenience but an existential economic threat.
The Resilience of Large Economies
Large economies like the United States, China, and the European Union are uniquely equipped to withstand tariff shocks. Their vast domestic markets absorb a significant share of production, reducing dependence on any single export destination. Diversified industrial bases allow them to shift production to less affected sectors.
Their economic and political weight also grants substantial bargaining power. The US-China tariff exchanges demonstrated that both nations could leverage large domestic markets and diversified economies to mitigate immediate impacts - even as the tariffs remained in place. When the US imposed tariffs on Chinese goods, China retaliated with targeted counter-tariffs while simultaneously accelerating domestic consumption policies and diversifying trade relationships toward ASEAN, the Middle East, and Africa.
The EU responded to tariff threats with its own trade defence instruments and by deepening bilateral agreements with Mercosur, Japan, and Australia - options available only to economic blocs with the scale to offer reciprocal market access.

The Vulnerability of Small Economies
Small economies face a fundamentally different set of constraints:
Export concentration: Many small economies depend heavily on a narrow range of products sold to a limited number of markets. Bangladesh, the world’s second-largest apparel exporter, sends approximately 18% of its exports to the US. A 37% tariff on those goods directly threatens an industry that employs millions and drives the country’s GDP growth.
Limited bargaining power: Small economies lack the market access leverage needed to negotiate tariff reductions. They cannot credibly threaten retaliatory tariffs because their imports from the US are too small to create meaningful economic pressure.
Import cost amplification: Many small economies depend on imports for essential goods, raw materials, and intermediate inputs. Tariffs increase these costs, driving domestic inflation and eroding consumer purchasing power - effects that compound in economies with limited fiscal buffers.
Disrupted development trajectories: Countries like Cambodia, Vietnam, and Bangladesh have built export-oriented development strategies over decades. Sudden tariff escalation can unwind years of industrial policy, infrastructure investment, and workforce development.
Supply Chain Reconfiguration
One of the most significant second-order effects of the 2025 tariffs is the real-time reconfiguration of global supply chains. Vietnamese exports, for example, are redirecting away from the US, Mexico, and China toward MENA markets, the EU, Korea, and other Asian trading partners. This redirection creates opportunities for some economies while disrupting established trade relationships for others.
For businesses operating across these disrupted corridors, the ability to settle transactions in multiple currencies, manage cross-border payments efficiently, and adapt to shifting trade flows is not a convenience - it is an operational necessity.
The BRICS Factor
The rise of BRICS nations (Brazil, Russia, India, China, South Africa - plus six new members added in January 2024) has added complexity to the trade landscape. BRICS members are actively pursuing alternatives to dollar-denominated trade and Western financial infrastructure, with initiatives including:
- The New Development Bank (NDB), which provides alternative financing for infrastructure projects in developing countries
- BRICS Pay and mBridge, targeting cross-border payment alternatives
- Bilateral local currency settlement agreements, now reaching approximately 90% of intra-BRICS trade
For smaller economies, BRICS expansion offers potential diversification away from Western market dependence - though the practical benefits remain uneven. The NDB’s lending capacity is still a fraction of World Bank or IMF resources, and BRICS internal coordination on trade policy is limited by competing national interests.
Implications for Businesses and Financial Infrastructure
The 2025 tariff escalation confirmed that trade disruption is not temporary. Businesses operating across borders need:
- Multi-currency payment capability to settle transactions across redirected trade corridors
- Real-time compliance with rapidly changing trade rules, sanctions, and documentation requirements
- Scalable infrastructure that can adapt as supply chains reconfigure
The Aerapass multi-asset exchange and global payments platform are designed for exactly this environment - providing cross-border payment infrastructure, multi-currency settlement, and regulatory compliance across jurisdictions affected by the new tariff reality.
The global economy is not returning to the low-tariff consensus of the pre-2025 era. Small economies face the greatest adjustment burden, and the financial infrastructure that serves them must be as adaptable as the trade environment demands.
Summary
The 2025 US tariff escalation - with average rates jumping from 2.8% to over 20% - disproportionately burdens small, export-dependent economies that lack the diversified markets and bargaining power to absorb or counter these trade shocks. Countries like Myanmar (49% tariff), Bangladesh (37%), and Cambodia (35%) face existential threats to industries that employ millions, while large economies such as the US, China, and the EU leverage domestic consumption, retaliatory capacity, and alternative trade agreements to mitigate the impact. As supply chains reconfigure in real time and BRICS nations explore alternatives to dollar-denominated trade, cross-border financial infrastructure capable of handling multi-currency settlement across shifting corridors has become an operational necessity.
Frequently Asked Questions
Q: Which small economies are most affected by US tariffs in 2025?
According to UNCTAD data, the small economies facing the steepest reciprocal tariff rates are Myanmar (49%), Vietnam (46%), Sri Lanka (44%), Laos (38%), Bangladesh (37%), and Cambodia (35%). Among the ten most affected countries globally, three are Least Developed Countries: Myanmar, Laos, and Bangladesh. Cambodia is particularly vulnerable, with over 25% of its total exports going to the US.
Q: How do tariffs impact Bangladesh garment exports?
Bangladesh is the world’s second-largest apparel exporter, with approximately 18% of its exports going to the US. The 37% reciprocal tariff rate directly threatens this industry, and ITC/UNCTAD projections estimate Bangladesh could lose $3.3 billion in annual US exports by 2029 under current tariff levels. The garment sector employs millions and is a primary driver of the country’s GDP growth, meaning the tariff impact extends well beyond trade figures into employment and development outcomes.
Q: How are global supply chains changing due to US tariffs?
The 2025 tariffs are driving real-time reconfiguration of global supply chains. Vietnamese exports, for example, are redirecting away from the US, Mexico, and China toward MENA markets, the EU, Korea, and other Asian trading partners. This redirection creates new trade corridors while disrupting established relationships, requiring businesses to manage cross-border payments and multi-currency settlement across an evolving set of destinations.
Q: What alternatives do BRICS offer small economies facing tariffs?
BRICS nations (now including six new members added in January 2024) are pursuing alternatives to dollar-denominated trade through the New Development Bank (NDB), BRICS Pay and mBridge cross-border payment systems, and bilateral local currency settlement agreements covering approximately 90% of intra-BRICS trade. For smaller economies, BRICS expansion offers potential diversification away from Western market dependence, though the practical benefits remain uneven - the NDB’s lending capacity is still a fraction of World Bank or IMF resources, and BRICS internal coordination on trade policy is limited by competing national interests.
