Federal Reserve Chair Kevin Warsh has followed his hawkish Jackson Hole message with action. At his first major policy test, the Federal Open Market Committee unanimously raised the federal funds target range by 25 bps to 3.75%-4.00%, the first increase since July 2023.

It was the first rate hike since July 2023, formally ending the long stretch of holds and cuts that preceded it.

The move was not unexpected. What matters more is what comes next. Warsh has made clear that he wants to reduce the Fed’s reliance on forward guidance, leaving markets with fewer explicit signals about the future path of rates. His broader agenda also points towards a more limited role for unconventional monetary tools outside periods of genuine crisis.

What Forced Fed's Hand

The committee's reasoning rested on a solid economy paired with stubbornly elevated inflation: August CPI and PPI readings stayed well above the 2% target, the labour market held steady, consumer spending remained resilient, and energy prices climbed on the back of the war in Iran.

August consumer inflation was 3.4% from a year earlier, while core inflation stood at 2.4%. Producer prices rose 5.4%, with energy prices up sharply. The Fed’s preferred personal consumption expenditures price index was running at 3.7% in July, with core PCE inflation at 3.3%. Gasoline and energy costs remain the biggest driver of the pressure, and this backdrop is what pushed the FOMC to hike rates. A sharp rebound in August retail sales further strengthened the case for tightening.

In its statement, the Fed attributed elevated inflation to supply shocks tied to "geopolitical developments," simplifying earlier language about energy-specific disruptions, and noted that the rate hike "will support a timelier return to the Committee's 2% goal."

The updated Summary of Economic Projections showed slightly higher expected GDP growth—2.2% in 20226, 2.3% in 2027—and inflation—3.7% in 2026 and 2.3% in 2027) than the June forecast. The committee penciled in two further hikes — one later this year and one in 2027 — before an eventual path toward rate cuts.

Over the longer run, officials see the Fed funds rate settling between 3.0% and 4.0%, with PCE inflation not reaching the 2.0% target until 2029, a year later than projected in June. As a corollary, the neutral real Fed rate is placed around 1-2%.

Warsh's approach continues to be defined by two core convictions: a reduced role for forward guidance, aimed at weaning markets off dependence on Fed signalling, and a preference for steering policy primarily through near-term rate moves — the Fed funds rate — rather than managing the long end of the yield curve. He has also made clear that balance sheet expansion should not be treated as an active monetary policy tool.

While the full contours of his new framework — built around policy surprises rather than explicit guidance, in service of his "no tolerance for persistently elevated inflation" pledge — have yet to be unveiled, he has already launched five task forces reviewing Fed operations across communications, balance sheet policy, data, productivity and jobs, and inflation frameworks.

Two elements of Warsh's message could be read as comparatively less hawkish. First, he attributes the current bout of elevated inflation largely to supply-side pressure from exogenous geopolitical factors rather than demand-side momentum. Second, he views the near-term crowding-out effect of fiscal imbalances and AI-related funding demand as less durable than many fear, betting that AI investment will eventually generate productivity gains that offset inflationary pressure.

Safety Net?

Markets will increasingly need to assess Fed policy through the lens of the inflation trajectory, labour market conditions, and productivity trends, with the Fed funds rate serving as the primary instrument as quantitative tools recede into the background.

In practice, this means markets can no longer take the Fed's management of the yield curve for granted: as balance sheet policy shifts toward shorter-maturity holdings, the Fed's implicit backstop on long-end yields will diminish, and market-determined long yields will carry more weight as a gauge of economic and inflation expectations.

A shift toward a more conventional, less market-managing framework is arguably a welcome development and a step toward greater Fed independence — but it also creates a visible tension with the Treasury, which has been leaning on buybacks and operation-twist-style tactics to manage the long end. That friction could send mixed signals to markets, even if the Fed's stance ultimately prevails, as suggested by the recent breach of the 5% mark on the 10-year yield.

The biggest risk to this outlook is timing: the Fed may be pricing in AI-driven productivity gains sooner, and more generously, than is realistic. Rising CDS spreads among AI-linked companies suggest those productivity gains could be back-loaded, meaning the crowding-out effect of AI capex may persist well into 2028 — even as continued protectionism adds further upside risk to inflation.
