The ongoing trade war and wider geopolitical volatility remains a major source of downside risk for the UK and global economies. The volume of global trade of goods and services is expected to slow to +0.6% in 2026 from +2% in 2025, according to Allianz Trade analysis. Despite the UK-US trade deal implemented in June, which reduces US tariffs on UK exports like cars, steel, and aerospace products, US tariff hikes are expected to impact UK GDP growth in 2026 by just under -0.2pp.
Heightened protectionism is perhaps the greatest threat to the global economy. We assign a 45% probability of global trade entering recession due to further US tariff escalation through Sector 232 tariffs, removal of product exclusions, and an end of the US/China truce. Such a scenario would have a severe negative impact on global growth, with downward pressure on global prices and higher interest rates. In addition, geopolitical tensions could rise further, with a NATO-Russia conflict, an escalation in the Middle East, and open conflict between China and Taiwan as potential risks.
