The global economy is a delicate balance of interconnected risks and opportunities, and the second half of 2026 is no exception. While the US-Iran peace agreement holds the key to determining the trajectory of the global economy, it is just one of many factors that could shape the coming months. In this article, I will explore the key risks and opportunities that could impact the global economy in the second half of 2026, and offer my own analysis and commentary on each.
The US-Iran Peace Agreement: A Coin Flip with a $20 Spread
The US-Iran peace agreement is a critical factor in determining the global economy's trajectory. If the agreement holds, the global economy could get an energy-driven disinflation tailwind, with cheaper oil feeding through to household incomes. However, if the agreement breaks down, the consequences would not be limited to the oil market. The recent exchange of attacks between the US and Iran has raised the risk that the interim agreement to halt fighting in the war could break down, and oil prices have already reacted with a 3% increase.
In my opinion, the US-Iran peace agreement is a coin flip with a $20 spread. While Oxford Economics forecasts a durable deal, Morgan Stanley predicts crude climbing back to $90 a barrel by the end of the year, and the World Bank is even more cautious, forecasting Brent crude to average about $94 a barrel this year. The recent exchange of attacks is testing the fragile truce, and the outcome of the deal is far from certain.
Trade Tensions: A Risk to the Global Economy
Trade tensions are another risk that could reshape the global economy. The US Section 122 tariffs are due to expire on July 24, but Washington has already lined up replacement levies under Section 301. Oxford Economics expects the changes to push effective tariff rates higher, and Europe is also taking a tougher stance against China. These trade tensions also feed into the AI boom that has powered financial markets this year.
From my perspective, the US-China trade war is a complex and multifaceted issue. While the tariffs and trade restrictions may have a negative impact on the global economy, they also present an opportunity for innovation and diversification. The AI boom, for example, could be a result of the increased focus on technology and innovation, rather than a direct consequence of the trade war. However, the potential for a tech bust scenario, where US technology stocks fall by 25% over the course of a year, is a real risk that could have a significant impact on the global economy.
Central Banks, Ballots, and the Calendar
The final dominoes in the global economy are policy and politics. Oxford Economics expects the major central banks to prove 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 nearest test is the Federal Reserve's rate decision later this month, and beyond that lie November's US midterms and Israel's general election, both of which could influence the Middle East peace process.
In my view, the role of central banks in the global economy is critical. While they may be more dovish than financial markets anticipate, they could pivot quickly if certain risks materialize. The Federal Reserve's rate decision later this month is a key test, and the outcome could have a significant impact on the global economy. The US midterms and Israel's general election are also critical, as they could influence the Middle East peace process and have a ripple effect on the global economy.
The AI Boom: A Double-Edged Sword
The AI boom has powered financial markets this year, but it is also a double-edged sword. Oxford Economics notes that the US AI industry depends heavily on semiconductors and other hardware shipped from Northeast and Southeast Asia, the regions with the most to lose from any further disruption to commodities passing through the Strait of Hormuz. Meanwhile, the Bank for International Settlements (BIS) has warned that the AI boom increasingly rests on opaque "circular financing" between chipmakers, cloud giants, and artificial intelligence labs, as well as lightly regulated private credit, where lending to the sector has quadrupled in five years.
What makes this particularly fascinating is the potential for a tech bust scenario, where US technology stocks fall by 25% over the course of a year. Such a shock would cause the US economy to "grind to a halt," spilling over to technology exporters and investor sentiment worldwide, and leaving global growth 1.1 percentage points below Oxford Economics' baseline next year. The AI boom is a powerful force in the global economy, but it is also a risk that could have a significant impact on the global economy if it were to reverse.
Conclusion: A Delicate Balance of Risks and Opportunities
In conclusion, the global economy is a delicate balance of interconnected risks and opportunities, and the second half of 2026 is no exception. The US-Iran peace agreement, trade tensions, central banks, and the AI boom are all critical factors that could shape the global economy in the coming months. While there are risks and uncertainties, there are also opportunities for growth and innovation. It is important to stay informed and analyze the situation from a broader perspective to make informed decisions and navigate the challenges and opportunities that lie ahead.
