Federal Reserve Chair Kevin Warsh gave his first major speech as chair on Friday at the Fed’s annual Jackson Hole gathering, and the tone caught markets off guard. Warsh said inflation remains above the Fed’s target and that fighting price pressure needs to stay the Fed’s top priority right now. Investors had hoped for some hint of a coming rate cut or at least a softer tone. They got neither. All three major stock indexes closed lower after his remarks, and traders quickly raised the odds of a rate hike at the Fed’s September meeting to nearly 61%.
The bigger story is what happened in the bond market afterward. The 30-year Treasury yield has climbed since Warsh spoke Friday, pushing back toward 5.27%, close to the high that rattled markets in late July and led the Treasury Department to step in and buy back more bonds to calm things down, a move we detailed closely at the time. Part of Monday’s move also came from oil prices jumping after renewed fighting between the US and Iran over the weekend.
Here is the part worth understanding clearly. When long-term Treasury yields rise, it usually means one of two things is happening, either investors expect higher inflation ahead, or they simply want more return for tying up their money for 30 years, regardless of inflation. Right now, it is almost entirely the second reason. Expectations for long-term inflation have barely moved, and have actually ticked down slightly. Investors are not panicking about inflation over the next three decades. They are just demanding a higher price to hold long-term government debt, a shift that can be driven by how much the government is borrowing, how fast the economy is expected to grow, or simply less certainty about where policy is headed. Warsh himself hinted at this Friday, saying he would be hard-pressed to call current financial conditions restrictive, a comment that leaves plenty of room for long-term rates to keep climbing even without the Fed making another official move.
That makes 5.3% the level worth watching most closely. A sustained move above it would push borrowing costs back into the same territory that unsettled markets last month.
For companies operating below the $2 billion market cap threshold, this distinction matters. Small and microcap companies typically carry more variable-rate debt than large companies, so their borrowing costs are especially sensitive to moves like this. If rising rates are being driven by investors simply wanting more compensation to hold long-term debt, rather than fear of runaway inflation, that pressure may prove harder to ease with a single Fed decision than markets first assumed when Warsh took over.
