Global Growth Stalls, Inflation Soars

The surge in American tariffs hasn't happened in a vacuum; it has sent shockwaves across the global economy, impacting growth, inflation and the very fabric of international trade.

The International Monetary Fund (IMF) drastically cut its global growth forecast for 2025 and 2026 to 2.8-3.0%, a cumulative downgrade of approximately 0.8 percentage points, primarily blaming the abrupt tariff increases and associated uncertainty. Similarly, the World Bank projects a sharp slowdown in global trade growth, decelerating from 3.4% in 2024 to around 1.8% in 2025, revising its forecast down by roughly 1.3 percentage points since January. These figures unequivocally point to a significant dampening effect on economic expansion worldwide.

Tariffs act as a direct cost push, fuelling inflation. In the United States, the IMF raised its inflation forecast by about 1 percentage point. The Yale Budget Lab estimates that all 2025 tariffs will hike the US price level by 2.3% in the short run, translating to an average per household consumer loss of $3,800 annually. For trading partners, tariffs primarily represent a negative demand shock, pushing foreign customers away from their products. This suggests that the burden of tariffs largely falls on consumers, both domestically and internationally, through higher prices.

 

Supply Chains Under Siege

Sweeping US tariff increases in 2025 are poised to trigger sharp contractions in global trade. Trade flows are expected to shrink by between 5.5% and 8.5% relative to the pre-shock economy. Crucially, trade flowing through Global Value Chains (GVCs)—shipments crossing multiple borders—is projected to shrink by roughly 2 percentage points more than direct bilateral trade, with particularly steep declines in sectors like "transport equipment" (16% contraction) and "electrical equipment and electronics" (12% contraction).

Tariffs directly disrupt global supply chains by inflating costs for imported goods, which can lead to higher consumer prices, loss of market share, and job losses in supply chain-dependent industries. This shock is expected to "distort production patterns and drive a sharp reconfiguration of global value chains, resulting in a less efficient and more opaque trade system". This forces companies to actively re-evaluate and potentially shift their sourcing locations. While direct trade between the US and China may "collapse," indirect exports of Chinese products to the US via third countries (e.g., Mexico, Korea, Vietnam) are proving far more resilient. This highlights a significant shift towards more complex, multi-country supply routes. The increased unpredictability of offshore costs due to tariffs also strongly incentivises companies to consider reshoring or nearshoring as a means of diversifying supply chains, reducing tariff exposure, and gaining greater cost predictability.

 

The Hidden Costs of Tariffs

While tariffs are legally paid by importing businesses in the country where they apply, the evidence clearly shows these costs are not absorbed solely by importers. Higher tariffs inflate costs for companies, leading to higher prices for consumers. The Yale Budget Lab quantifies this, estimating a consumer loss of $3,800 per household annually due to all 2025 tariffs. For businesses, this means lower operating margins and a potential loss of sales and market share. This indicates that the financial burden of tariffs extends far beyond the initial import duty, impacting consumer purchasing power and the overall competitiveness and profitability of businesses throughout the supply chain. Businesses must understand that tariffs are not just a direct cost; they trigger a cascading series of economic effects that reduce consumer demand, increase input costs, and ultimately erode profitability across the value chain. This demands a careful re-evaluation of pricing strategies, aggressive cost control, and potentially a strategic re-assessment of target market segments to absorb or mitigate these widespread impacts.

 

Forced Adaptation and New Inefficiencies

The data consistently points to a significant reconfiguration of global value chains and a strong push towards diversifying supply chains away from China through reshoring or nearshoring. However, it's explicitly warned that this forced adaptation results in a "less efficient and more opaque trade system". Furthermore, tariffs can lead to "loss of livelihood for people working upstream in the supply chain" in affected countries, indicating broader societal costs. This suggests that while businesses are compelled to adapt their supply chains in response to tariff pressures, the resulting networks may not be optimised for traditional metrics like cost-efficiency or speed. Instead, they might represent a reactive, defensive strategy aimed at minimising tariff exposure, potentially at the expense of overall supply chain efficiency and transparency. Businesses need to approach supply chain diversification and reshoring with caution and a comprehensive understanding of the trade-offs involved. Simply relocating production may not solve all problems; it can introduce new inefficiencies, increase transaction costs, and potentially lead to unforeseen quality control or regulatory hurdles. The strategic decision to diversify or reshore must be carefully weighed against these potential downsides, requiring deep analysis of the total landed cost, operational complexities, and the long-term strategic fit of the new supply chain configuration.

 

Uneven Impacts Across Economies

The trade growth downgrade since January 2025 is most pronounced for advanced economies, with their 2025 trade growth projected to be roughly half of earlier forecasts. The euro area, despite facing relatively lower effective tariffs, saw its growth forecast revised down by 0.2 percentage points. Emerging Market and Developing Economies (EMDEs) face significant cuts to their trade growth forecasts, by about one-quarter. Those deeply integrated into global value chains or heavily reliant on the United States and other advanced markets—such as EMDEs in Latin America and the Caribbean, and Europe and Central Asia—are particularly poised for weaker trade growth. The increased external volatility from tariff adjustments may be especially difficult for these economies to navigate.

The United Kingdom, a relatively open economy with international trade equivalent to 62% of its GDP in 2024, is likely to be more affected by global trade disruption than less open economies. While direct effects of US tariffs on UK firms' costs may appear limited (only 2% of total import costs came directly from the US), indirect effects through global supply chains can significantly raise costs. Surveys show that 27% of UK firms expected lower sales due to US trade policy changes, with direct exporters to the US more likely to anticipate negative impacts on both sales and investment.
