DoubleLine CEO Gundlach advocates for Fed rate hike in October

Jeffrey Gundlach, the billionaire bond investor who runs DoubleLine Capital, says he would support the Federal Reserve raising interest rates at its October meeting if current economic data holds steady. In a market environment where most investors spent the last two years waiting for cuts, Gundlach is making the contrarian case that the Fed needs to go the other direction.

What Gundlach is actually saying

During his September 8 “Gundlach Unlocked” webcast, the DoubleLine CEO laid out a case for a 50 basis point increase in the federal funds rate. A half-point hike would push the effective rate from its current range of roughly 3.63% to 3.75% up toward 4.25%.

His reasoning centers on inflation dynamics that he says resemble the 1970s. Import and export price growth is running near 7%, according to Gundlach. Commodity prices have surged, with oil hovering around or above $100 per barrel.

Gundlach was skeptical that the Fed would act at the September meeting, even as market-implied probabilities put the odds of a hike at 55% to 60%. But looking ahead to the October 27-28 FOMC meeting, futures markets are pricing in a 64% chance of a rate increase.

His warning to the Fed was blunt: if policymakers remain inactive, long-term Treasury yields could spike dramatically higher. The 10-year Treasury yield is already sitting near 4.80%, while the 30-year has pushed past 5.25%.

Why this matters beyond bonds

The comparison to the 1970s is deliberate and ominous. That decade saw the Fed chase inflation with stop-and-start rate policies, ultimately requiring Paul Volcker’s brutal tightening campaign in the early 1980s to break the cycle.

On the equity side, Gundlach is recommending investors shift toward equal-weighted strategies rather than cap-weighted indexes, citing concentration risk in a handful of mega-cap stocks.

He’s also bearish on the US dollar, and that bearish dollar view feeds into his constructive stance on emerging markets.

The market implications

If the Fed does hike in October, fixed-income portfolios would face immediate mark-to-market losses as yields rise and bond prices fall. The 30-year yield above 5.25% is already causing stress in rate-sensitive sectors like housing and utilities.

A 50 basis point hike would also reset expectations across the entire yield curve. Corporate borrowers who locked in cheap debt during the low-rate era would face steeper refinancing costs as those obligations mature.

Market participants should watch the incoming economic data closely between now and October 28. If inflation readings remain elevated and commodity prices stay hot, the probability of a hike will only climb.
