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, is the 'key domino' that will determine the trajectory of the global economy. The report's author, Ryan Sweet, emphasizes the potential for a significant impact on energy prices and economic conditions, stating that the deal's durability is a 'coin flip'.
If the truce holds, oil prices are expected to average around $70 per barrel, which would lead to disinflation and ease financial conditions in emerging markets. However, if the agreement breaks down, the consequences could be far-reaching. The recent attacks in the Strait of Hormuz, involving Iran and Bahrain, have already caused a 3% increase in oil prices, with Brent crude trading above $76 a barrel. Sweet warns that a breakdown would not only raise oil prices but also disrupt AI supply chains, tighten financial conditions, and potentially influence political outcomes in the US and Israel.
The outlook for oil prices is divided, with Oxford Economics predicting an average of $70 per barrel, while Morgan Stanley forecasts a much higher price of around $90. The World Bank's cautious approach further highlights the uncertainty surrounding the peace agreement. The recent exchange of attacks serves as a test for the fragile truce, with the Strait of Hormuz traffic as a critical indicator. Sweet suggests that a return to pre-war traffic levels by mid-July would increase the chances of the agreement's success.
Trade tensions are another significant risk, with the US Section 122 tariffs set to expire and be replaced by Section 301 levies. This shift will likely increase effective tariff rates, impacting the global economy. Europe's tougher stance on trade, with numerous investigations against China, further adds to the trade-related risks. These tensions are intertwined with the AI boom, as the US AI industry heavily relies on Asian semiconductors, which could be disrupted by any Strait of Hormuz-related issues.
The Bank for International Settlements (BIS) has raised concerns about the AI sector's reliance on opaque financing and lightly regulated private credit. A potential AI downturn could trigger a sharper correction than traditional banking crises. Sweet's modeled scenario of a 25% drop in US tech stocks illustrates the potential impact on the global economy, with a 1.1 percentage point reduction in growth.
Policy and politics also play a crucial role. Central banks are expected to be dovish, but could pivot if economic conditions worsen. The Federal Reserve's rate decision and the US midterms in November are key events that could influence the Middle East peace process. Additionally, Germany's state elections in September may impact the eurozone economy and fiscal policy. Despite these risks, Oxford Economics highlights potential upside, such as AI-driven productivity gains and a resilient EU economy.
In conclusion, the second half of 2026 presents a complex global economic landscape, with the US-Iran peace agreement as the central focus. The outcome of this agreement will have far-reaching implications for energy prices, trade, AI, and political stability. As Sweet notes, the global economy is like a 'coin flip' with a significant spread, and the consequences of each outcome could be substantial.
