A Number on the Damage
The OECD lowered its forecast for global growth this year to 2.8%, down from the 3.4% pace of 2025. It called the conflict in the Middle East "the dominant force shaping global economic prospects."
That phrasing matters. Other forecasters have flagged risk. The OECD is the first major institution to fold the full cost of the energy shock into its baseline numbers, including the disruption to shipping through the Strait of Hormuz and the damage to Gulf energy infrastructure.
The downside case is worse. If the disruption drags on, the OECD sees global growth slowing to 2.1% in 2026 and 1.8% in 2027. US growth in the baseline drops to about 2.0%.
Why "Stagflation" Is the Word That Matters
The report does not just cut growth. It also lifts inflation. The OECD now expects consumer prices across the G20 economies to rise 4.0% in 2026, up from 3.4% last year, before easing in 2027.
Growth down and inflation up at the same time is the textbook definition of stagflation. It is the one combination that gives a central bank no easy move. Cut rates to help growth, and inflation runs hotter. Raise rates to fight inflation, and the slowdown gets worse.
That trap lands at an awkward moment for stocks. The S&P 500 trades near 22 times forward earnings, close to the top of its 10-year range. The 10-year Treasury yield sits around 4.48%. Expensive stocks and rising yields are a fragile pairing when the growth outlook is being cut.
The Split Is Already Showing in Prices
You can see the framework playing out in real time. The Dow is up sharply today as money rotates into blue-chip and defensive names, while the Nasdaq is down more than 1% as higher-priced technology shares slip. Defensive sectors tend to trade at lower earnings multiples, and energy names carry higher dividend yields, which is part of their appeal when growth is in doubt.
Oil is easing, with West Texas crude near $95 on hopes that a US-Iran ceasefire framework holds. Brent is trading near $97. But the relief is fragile. Reported strikes continued this week, and crude loadings inside the Gulf remain very low, so the supply squeeze the OECD described has not actually cleared.
Gold is trading near $4,500, holding most of its safe-haven gains. The metal tends to do well when real yields are uncertain and investors want protection from both inflation and conflict.
What to Watch From Here
The next three data points will test the stagflation story. May payrolls land Friday, with a consensus near 80,000 jobs after a stronger-than-expected private hiring report this week. A hot number would make the case for rate relief even harder.
Then comes the May inflation report on June 10, followed by the Federal Reserve meeting on June 16 and 17, the first under the new chair. If oil stays high and jobs stay strong, the meeting could land far more hawkish than the market is positioned for.
The OECD gave the slowdown a number. The data over the next two weeks will show whether the prolonged-disruption scenario, the bad one, is the path the economy is actually on.
