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 is a coin flip, with a $20 spread between the forecasts of Oxford Economics and Morgan Stanley. The former predicts a durable deal that would keep oil prices in the low $70s per barrel, while the latter expects a breakdown that would push prices back to $90 a barrel.
What makes this situation particularly fascinating is the potential impact on global supply chains and financial markets. The Strait of Hormuz is a critical chokepoint for oil transportation, and any disruption could have far-reaching consequences. If the truce holds, we might see a boost in AI supply chains in Asia, with cheaper oil feeding through to household incomes and easing inflation and financial conditions. However, if the deal breaks, the oil market won't be the only one affected. The regional crossfire between the US and Iran could increase pressure on AI supply chains, force central banks to be hawkish, and tighten financial conditions.
One thing that immediately stands out is the role of tariffs and trade. The US Section 122 tariffs are set to expire on July 24, but Washington has already lined up replacement levies under Section 301. This could push effective tariff rates higher, as the US seeks to maintain monthly tariff revenues of between $25 billion and $30 billion. Europe is also taking a tougher stance, with the European Commission conducting more than 50 trade-defence investigations against China, up from 17 a year ago. These trade tensions also feed into the AI boom that has powered financial markets this year.
What many people don't realize is the potential impact on central banks and the calendar. Oxford Economics expects the major central banks 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. In September, German state elections could also test the coalition behind Germany's fiscal policy, a key driver of the eurozone economy.
If you take a step back and think about it, the global economy is a complex web of risks and opportunities. The US-Iran peace agreement is a critical factor that could either bring stability or chaos. The impact on oil prices, supply chains, and financial markets could be significant, and the consequences could be far-reaching. The calendar is also a critical factor, with key events and elections that could influence the Middle East peace process and the global economy. It's a delicate balance, and the outcome is far from certain.
In my opinion, the global economy is a rollercoaster ride, and the second half of 2026 is no exception. The US-Iran peace agreement is a critical factor that could either bring a much-needed energy-driven disinflation or trigger a second oil shock. The impact on global supply chains and financial markets could be significant, and the consequences could be far-reaching. The calendar is also a critical factor, with key events and elections that could influence the Middle East peace process and the global economy. It's a delicate balance, and the outcome is far from certain.
