OECD lifts U.S. growth to 2.2% on AI spending, but sees 2027 inflation at 2.6%, above the Fed's own forecast

The Organisation for Economic Co-operation and Development raised its forecast for global growth this year to 2.9% from 2.8% in June, saying spending on artificial intelligence infrastructure has helped the world economy absorb the energy shock from the Middle East conflict. It trimmed 2027 to 3.0% from 3.1%, after 3.4% growth in 2025, Reuters reported from the Paris-based group's interim outlook published Wednesday.

For the United States, the OECD now sees growth of 2.2% in 2026 and 2.1% in 2027, both upgrades from June, as heavy AI-related investment offsets weaker consumer spending. It projects U.S. inflation at 3.6% this year, easing to 2.6% in 2027, with tariffs and higher energy prices weighing on household purchasing power and business costs.

The revision that matters is on prices

The global growth upgrade was a tenth of a point. The inflation change was five times that size: the OECD now expects G20 inflation of 4.1% this year, up from 4.0%, and 3.6% in 2027, up from 3.1% in June. It said persistent price pressure could force central banks to adjust interest rates if it broadens out. Euronews reported the OECD also warned that "rising bond yields underline more than ever the need" for governments to contain spending and strengthen revenues.

The OECD put a number on the downside, too. If energy market jitters, a strong El Niño, surging bond yields and disappointing returns on AI investment all hit together, it estimated they could cut global growth by 0.7 percentage point next year and add 1.1 points to global inflation.

Where it sits against the Fed

The comparison traders will make is with the Federal Reserve's own projections from a week ago, when it raised its target range by a quarter point to 3.75% to 4%.

The two sets of forecasts are not built identically, and the Fed's figures are fourth-quarter PCE projections, so small gaps should not be over-read. But the direction is clear: the OECD sees slower U.S. growth next year and inflation that comes down less. The Fed's projections already show a median federal funds rate of 4.1% at the end of both 2026 and 2027, with no net cut next year. In June, the median for the end of 2027 was 3.6%.

Who it hits

For a business with a floating-rate credit line, that half-point change in the Fed's own 2027 path is the practical number. On a $250,000 balance, 0.5 percentage point is about $1,250 a year in extra interest compared with what the June projections implied. A forecast from the OECD that inflation will run hotter than the Fed expects adds to the risk that the path moves higher, not lower.

Bond markets were already moving that way. The 10-year Treasury yield closed at 4.96% on Tuesday, according to Treasury data, and CNBC reported it rose above 5.12% on Wednesday after stronger-than-expected business survey data. See our 10-year chart and our earlier report on rate-hike odds.
