The global economy's second half of 2026 hangs in the balance, with a delicate peace agreement between the US and Iran as the pivotal factor. This agreement, according to Oxford Economics, could either provide an energy-driven disinflationary boost or trigger a second oil shock, impacting the world's financial markets and geopolitical landscape. The consultancy's optimism is balanced by the recognition that the deal's durability is uncertain, akin to a coin flip with a $20 price spread. This uncertainty is further compounded by the potential breakdown of the truce, as evidenced by recent military exchanges between the US and Iran, which have sent oil prices soaring and raised concerns about the stability of the Strait of Hormuz. The region's crossfire has already increased oil prices by over 3%, with Brent crude trading above $76 a barrel, and the risk of further escalation looms large.
The impact of this volatile situation extends beyond oil prices. A breakdown in the peace deal could disrupt AI supply chains in Asia, tighten financial conditions, and potentially alter the outcomes of crucial elections in the US and Israel. The US midterms and Israeli elections are particularly significant, as they could influence the Middle East peace process and the broader geopolitical landscape. Moreover, the US Section 122 tariffs, set to expire on July 24, are expected to be replaced with Section 301 levies, leading to higher effective tariff rates and impacting global trade dynamics.
Trade tensions are also escalating, with the European Commission conducting over 50 trade-defense investigations against China, a significant increase from a year ago. These investigations are part of a broader strategy to enhance economic security, which could have far-reaching consequences for global trade and the AI industry. The US AI sector heavily relies on semiconductors and hardware from Northeast and Southeast Asia, making it vulnerable to disruptions in the Strait of Hormuz. The Bank for International Settlements (BIS) has warned that the AI boom is built on opaque financing practices and lightly regulated private credit, with lending to the sector quadrupling in five years. A downturn in the AI sector could trigger a sharper correction than traditional banking crises, as it is heavily dependent on non-bank funding.
The global economy's outlook is further complicated by the actions of central banks. Oxford Economics anticipates that major central banks will adopt a dovish stance, but they may pivot quickly if the Strait of Hormuz situation deteriorates or AI-related prices indicate supply stress. The Federal Reserve's rate decision in July, following a soft jobs report in June, will be a critical test. Additionally, the US midterms in November and Israel's general election in late October could have significant implications for the Middle East peace process, while German state elections in September may impact the eurozone economy and fiscal policy.
Despite the risks, Oxford Economics highlights potential upside, such as stronger AI-driven productivity and the EU's resilience in the second quarter. However, the accuracy of these forecasts is questionable, as the typical Oxford Economics forecast miss is nearly a full percentage point, and the range around this assessment is wider than usual. The global economy's trajectory in the second half of 2026 remains uncertain, with the US-Iran peace agreement as the central domino that could either stabilize or disrupt the delicate balance of global economic risks.
