Market strategist James E. Thorne has a message for Federal Reserve Chair Kevin Warsh: pump the brakes. After October inflation came in hotter than forecast, Thorne warned that aggressive rate hikes risk turning what looks like an easing supply shock into a full-blown recession.

October CPI Fuels Aggressive Rate Hike Fears

"The Fed Is Fighting the Wrong Inflation. Warsh needs to show leadership!" Thorne wrote in an X post, taking aim at the central bank's communications and Governor Christopher Waller's openness to a half-percentage-point increase in December.

Thorne had previously warned that the Fed risked repeating its 2008 policy mistakes by raising borrowing costs in response to an energy-driven inflation shock.

The numbers: October's consumer price index rose 0.4% from September, slowing from September's 0.6% increase, the Bureau of Labor Statistics reported Tuesday. Core prices, excluding food and energy, climbed 0.3% for a third consecutive month. Both measures exceeded economists' expectations, raising fresh concerns about another Fed rate hike.

Waller, speaking Tuesday at a London conference, said a 50-basis-point December hike "should be considered" if core inflation remained around 0.3% or higher. Thorne's response was blunt: "A tenth above expectations, and out comes the sledgehammer. That's reckless!!"

U.S. Treasury yields surged Tuesday following the hotter-than-expected October inflation report, reflecting growing expectations of further Federal Reserve tightening. The benchmark 10-year Treasury yield climbed 12.55 basis points to 4.988%, while the policy-sensitive 2-year yield jumped 18.44 basis points to 4.731%, its biggest daily increase since April 2025.

The bond market selloff also dragged down Treasury-focused exchange-traded funds, with the iShares 20+ Year Treasury Bond ETF (TLT) falling 1.32% to $80.88 and the iShares 7-10 Year Treasury Bond ETF (IEF) declining 0.86% to $91.01 during Tuesday's session.

Thorne Challenges Fed Messaging And Housing Concerns

Thorne also challenged Warsh's preference for scaling back forward guidance and the Fed's interest-rate projections while allowing officials to publicly express their individual policy views.

"That does not end forward guidance. It hands the microphone to hawks and disgruntled colleagues," he argued, warning that conflicting public statements could shape market expectations and undermine consistent central bank communication.

Thorne also added that higher borrowing costs cannot resolve housing supply shortages. He warned that further rate increases could discourage homebuilding and keep existing homeowners locked into lower-rate mortgages, limiting housing market activity. Last month, he argued that higher interest rates could not reverse supply-driven price increases, warning that policymakers were misdiagnosing the underlying inflation problem.

Energy Inflation Slows, But Prices Continue to Rise

The BLS reported shelter prices rose 0.3% in October, while energy prices increased 0.7%, sharply below September's 5.2% gain. Thorne pointed to falling crude and wholesale gasoline prices as evidence the energy shock was reversing, alongside inflation swaps below 2%.

Separate BLS data released last Thursday showed third-quarter productivity increased at a 3.6% annualized rate while unit labor costs fell 0.7%. The Dallas Fed's October 29 update put six-month annualized trimmed-mean inflation at 2.4%, although its 12-month reading stood at 2.3%.

"These figures demand judgment, not reflexive tightening," Thorne wrote, warning that further hikes amid easing costs could "risk turning a temporary inflation shock into recession."
