US-Iran Peace Agreement Hangs in Balance, Global Economy at Risk
A US-Iran peace agreement is the key factor determining the global economy's trajectory in the second half of 2026. Oxford Economics forecasts 3.1% annualised growth if the deal holds, but warns of a second oil shock if it breaks. The agreement's durability will impact inflation, financial conditions, and tech valuations globally.
Key points
- Oxford Economics forecasts 3.1% annualised global economic growth in the second half of 2026, driven by cheaper oil, if the US-Iran peace agreement holds.
- The consultancy puts the odds of a durable deal at 'a coin flip', with Brent crude averaging in the low $70s per barrel if the agreement is maintained.
- A breakdown in the agreement could lead to a second oil shock, with consequences extending beyond the oil market.
- The US military attacked Iran after Tehran struck three ships in the Strait of Hormuz, raising the risk of the interim agreement breaking down.
- Regional crossfire between the US and Iran has followed a pattern of similar attacks during the deal's shaky ceasefire.
The global economy is on a knife's edge as the US-Iran peace agreement hangs in the balance. Oxford Economics, a leading consultancy, has warned that the agreement's durability will determine whether the global economy gets an energy-driven disinflation tailwind or absorbs a second oil shock. If the deal holds, the consultancy expects the global economy to accelerate, forecasting 3.1% annualised growth in the second half of 2026, driven by cheaper oil feeding through to household incomes. However, the odds of a durable deal are slim, with Oxford Economics putting the chances at 'a coin flip'. If the agreement breaks down, the consequences would not stay contained to the oil market, with a second oil shock potentially having far-reaching impacts on global inflation, financial conditions, and tech valuations. The recent exchange of fire between the US and Iran has raised the risk of the interim agreement breaking down, with neither country immediately signalling a willingness to step back from the brink.
