The global economy is a delicate balance of interconnected risks, and the second half of 2026 is no exception. The US-Iran peace agreement is the key domino that could either bring a much-needed energy-driven disinflation or trigger a second oil shock, as Oxford Economics' chief global economist Ryan Sweet puts it. This agreement's durability is crucial, and Sweet's prediction of a 'coin flip' odds highlights the uncertainty surrounding it. If the truce holds, oil prices could average in the low $70s per barrel, easing inflation and financial conditions across emerging markets and tech valuations. However, if it breaks, the consequences would extend far beyond the oil market, impacting AI supply chains, central bank policies, and even the outcomes of elections in the US and Israel.
The recent exchange of attacks between the US and Iran has already caused oil prices to surge by over 3%, with Brent trading above $76 a barrel. This incident serves as a stark reminder of the fragility of the truce and the potential for further escalation. The Strait of Hormuz, a critical chokepoint for oil traffic, is a bellwether for the deal's health. If traffic returns to 75% or more of pre-war levels by mid-July, the agreement is likely holding; otherwise, it could break down. The Lebanon clause, which Iran can invoke in response to Israeli strikes, is another critical indicator, with military or rhetorical responses having significant implications.
Trade tensions are another risk factor that could reshape the economic outlook. US Section 122 tariffs are set to expire on July 24, but replacement levies under Section 301 will push effective tariff rates higher. Europe is also taking a tougher stance against China, with over 50 trade-defense investigations open and a broader economic security strategy planned. These trade tensions feed into the AI boom, which has driven financial markets this year. The US AI industry relies heavily on semiconductors and hardware shipped from Northeast and Southeast Asia, regions that could be significantly impacted by any disruption to commodities passing through the Strait of Hormuz.
The Bank for International Settlements (BIS) has warned that the AI boom is increasingly dependent on opaque 'circular financing' and lightly regulated private credit. An AI downturn could trigger a sharper and faster correction than a traditional banking crisis, as the sector's reliance on non-bank funding means that lending to the sector has quadrupled in five years. The BIS's Asia-Pacific chief, Zhang Tao, cautioned that the sector's reliance on non-bank funding means an AI downturn could trigger a sharper and faster correction than a traditional banking crisis.
Central banks are another critical factor in the global economy. Oxford Economics expects them to be more dovish than financial markets currently anticipate, but they could pivot quickly if traffic through the Strait of Hormuz falters or AI-input prices signal supply stress. The Federal Reserve's rate decision later this month and the US midterms in November are key tests for the Middle East peace process. German state elections in September could also impact the eurozone economy by testing the coalition behind Germany's fiscal policy.
While Oxford Economics highlights risks, it also flags genuine upside, such as stronger AI-driven productivity and an EU economy that weathered the second quarter surprisingly well. Whether the resilience in Europe is real will be evident first in Germany and in credit data. A contraction in eurozone bank lending would indicate that corporates are absorbing margin compression without cutting investment and drawing down credit lines, which would strengthen the case that underlying momentum in the economy is better than expected.
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 factors. The risks are significant, but so are the potential rewards. The resilience of the EU economy and the potential for stronger AI-driven productivity offer reasons for optimism. However, the fragility of the truce and the potential for escalation in the Middle East serve as a stark reminder of the delicate balance of global economic risks.
