The global economy is poised for a pivotal moment in the second half of 2026, with a delicate balance of risks hanging in the balance. The US-Iran peace agreement, a potential energy-driven disinflation tailwind, and the fate of the global economy are all intertwined, according to Oxford Economics. This agreement, as described by chief global economist Ryan Sweet, is the 'key domino' that will determine the trajectory of the global economy. If it holds, the world could see a surge in growth, with annualized growth reaching 3.1% in the second half of the year, driven by cheaper oil prices and their positive impact on household incomes. However, the odds of a durable deal are described as a 'coin flip', and the consequences of its failure are far-reaching.
The recent exchange of attacks between the US and Iran, including the US military's attack on Iran after Tehran struck three ships in the Strait of Hormuz, has already caused oil prices to spike by over 3% by Wednesday morning, with Brent trading above $76 a barrel. This regional crossfire raises the risk of the interim agreement breaking down, which could lead to a second oil shock and further economic turmoil. The impact of such a breakdown would extend beyond the oil market, affecting AI supply chains in Asia, central banks' monetary policies, and potentially influencing the outcomes of the US midterms and Israeli elections.
The outlook for oil prices is a subject of debate, with Oxford Economics forecasting a low of $70s per barrel, while Morgan Stanley predicts a much higher price of around $90 per barrel by the end of the year. The World Bank, too, is cautious, forecasting an average of about $94 per barrel and a slowdown in global GDP growth to 2.5% in 2026. The Strait of Hormuz, a critical chokepoint for oil traffic, is a key indicator of the deal's stability, with a sustained return to pre-war traffic levels by mid-July being a crucial test.
Trade tensions are another significant risk, with US Section 122 tariffs set to expire on July 24th, replaced by Section 301 levies. This shift is expected to push effective tariff rates higher, impacting the US economy and global trade. Europe is also taking a tougher stance against China, with a significant increase in trade-defence investigations, indicating a broader economic security strategy. These trade tensions have implications for the AI industry, which heavily relies on semiconductors and hardware from Asia, a region that could face disruptions due to the Strait of Hormuz.
The AI boom, a significant driver of financial markets, is also under scrutiny. The Bank for International Settlements (BIS) warns that the sector's reliance on opaque 'circular financing' and lightly regulated private credit could lead to a sharper correction than traditional banking crises. The potential for a tech bust scenario, where US technology stocks fall by 25% over a year, could have a devastating impact on the US economy and global investor sentiment.
Central banks' policies and political events are the final dominoes in this complex game. Oxford Economics expects central banks to be dovish, but they could quickly pivot if traffic through the Strait of Hormuz falters or AI-input prices signal supply stress. The Federal Reserve's rate decision, the US midterms, and Israel's general election are all critical events that could influence the Middle East peace process and global economic stability. Additionally, German state elections in September could impact the eurozone economy and the coalition behind Germany's fiscal policy.
Despite the risks, Oxford Economics highlights potential upside, including stronger AI-driven productivity and a resilient EU economy. The resilience in Europe will be evident in Germany's credit data and corporate behavior, with the underlying momentum in the economy being a key indicator. However, the typical Oxford Economics forecast miss and the wide range around this assessment indicate that the path ahead is fraught with uncertainty, and the global economy remains a delicate balance of risks and opportunities.
