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. If it holds, we could see an energy-driven disinflation tailwind, with cheaper oil feeding through to household incomes and easing inflation across emerging markets and tech valuations. However, if it breaks, the consequences would be far-reaching, impacting not just oil prices but also AI supply chains, central bank policies, and geopolitical elections.
The recent exchange of attacks between the US and Iran has already sent oil prices soaring, with Brent crude trading above $76 a barrel. This highlights the fragility of the truce and the potential for further escalation. The Strait of Hormuz, a critical chokepoint for oil traffic, is a key indicator of the deal's health. If traffic returns to 75% or more of pre-war levels by mid-July, the odds of the agreement holding increase. Conversely, a breakdown in the deal could lead to higher oil prices, increased pressure on AI supply chains, and tighter financial conditions.
The US-Iran peace agreement is not the only risk factor. Trade tensions, particularly those between the US and China, are also on the rise. US Section 122 tariffs are set to expire, but the US is already planning to impose new levies under Section 301. This, coupled with Europe's tougher stance on trade defenses, could disrupt the AI boom, which heavily relies on Asian semiconductors and hardware. The Bank for International Settlements (BIS) warns that the AI sector's reliance on non-bank funding makes it vulnerable to a sharper correction than traditional banking crises.
Central banks, too, are in a delicate position. Oxford Economics expects them to be dovish, but they could quickly pivot if the US-Iran situation deteriorates or AI supply prices signal stress. The Federal Reserve's rate decision later this month will be a crucial test, especially after June's soft jobs report. The US midterms and Israeli elections in November, as well as German state elections in September, could also influence the Middle East peace process and the eurozone economy.
Despite these risks, Oxford Economics highlights potential upside. Stronger AI-driven productivity and a resilient EU economy are possible. However, the key to this resilience lies in Germany and credit data. If corporates can absorb margin compression without cutting investment and drawing down credit lines, it would suggest a stronger underlying momentum in the economy. Conversely, a contraction in eurozone bank lending would indicate a more fragile situation.
In conclusion, the second half of 2026 is a critical period for the global economy, with the US-Iran peace agreement, trade tensions, and central bank policies as key determinants. The potential for a tech bust, higher oil prices, and disrupted AI supply chains adds to the uncertainty. As an expert, I would advise investors and policymakers to closely monitor these risks and be prepared for a range of outcomes, as the global economy hangs in the balance.
