The global economy's second half of 2026 hangs in the balance, with a pivotal US-Iran peace agreement as the linchpin. This deal, according to Oxford Economics, could either provide an energy-driven disinflationary boost or trigger a second oil shock, setting off a chain reaction of economic consequences. The consultancy predicts a growth acceleration to 3.1% in the second half, driven by cheaper oil, but the deal's durability is uncertain, with a 50/50 chance of success. This uncertainty is reflected in varying forecasts from financial institutions.
The recent US-Iran military exchanges, including attacks on ships in the Strait of Hormuz, have already caused oil prices to surge by over 3%. The region's volatility raises concerns about the interim agreement's stability, with both countries maintaining their commitment to negotiations. The outcome of this tense situation will significantly impact oil prices and global supply chains, potentially affecting AI supply chains in Asia and central bank policies.
Trade tensions, particularly with the US Section 122 tariffs and Europe's increased trade-defence investigations against China, are another critical factor. These tensions are intertwined with the AI boom, which heavily relies on Asian hardware and non-bank financing. A downturn in the AI sector could trigger a sharper correction than traditional banking crises, as warned by the Bank for International Settlements (BIS).
The global economy's future also hinges on central bank policies and political events. Oxford Economics anticipates major central banks to be dovish, but they may pivot if the Strait of Hormuz situation deteriorates or AI prices indicate supply issues. Key events include the Federal Reserve's rate decision, the US midterms, Israel's election, and German state elections, all of which could influence the Middle East peace process and the eurozone economy.
Despite these risks, Oxford Economics highlights potential upside, such as AI-driven productivity gains and the EU's resilience in the second quarter. However, the accuracy of these forecasts is uncertain, with a wide range of potential outcomes. The global economy's trajectory in the second half of 2026 remains a high-stakes coin flip, with far-reaching implications for energy, trade, technology, and policy.
