September Rate Hike Expectations Rise After Warsh’s Jackson Hole Speech
Markets entered the new week focused on two major risks: renewed geopolitical tensions and the possibility that the U.S. Federal Reserve could raise interest rates at its September meeting.
The rate-hike debate intensified after Fed Chair Kevin Warsh delivered a hawkish speech at the Jackson Hole Economic Policy Symposium on Aug. 28. Warsh emphasized that inflation remains too high and suggested policymakers may need to act if price pressures do not move toward the Fed’s 2% target at a sufficient pace.
However, a September increase is still not a guaranteed outcome. CME FedWatch, which derives rate expectations from 30-Day Fed Funds futures, has placed the probability around the 60% area, meaning traders are leaning toward a hike but have not priced it as a certainty.
Warsh Puts Inflation Ahead of the Labor Market
Warsh’s remarks were interpreted as hawkish because he placed particular emphasis on inflation rather than signs of weakness in employment.
In his Jackson Hole speech, Warsh said the Fed’s preferred inflation measure, the 12-month PCE price index, was running at 3.7%, well above the central bank’s 2% target. He also pointed to a six-month PCE inflation rate of 4.1%. According to Warsh, recent inflation improvements have not been strong enough to establish that underlying price pressures are moving sustainably toward the Fed’s objective.
The Fed chair also highlighted the breadth of price increases. Over the previous 12 months, 54% of the 199 components in the PCE basket recorded price increases above 3%. That figure has fallen substantially from its post-pandemic peak, but remains considerably above the 32% average recorded during the two decades before the pandemic.
Why a September Hike Is Still Not a Done Deal
Despite the hawkish message, traders are not treating a September hike as certain. The probability implied by Fed funds futures remains close to, rather than overwhelmingly above, the level normally associated with a firmly established market consensus.
CME FedWatch is a market-based probability tool rather than a forecast issued by the Federal Reserve itself. It reflects the pricing of interest-rate futures and therefore can change quickly as new inflation, employment, Treasury-market and geopolitical data arrive.
That distinction matters for crypto markets. A probability near 60% means investors are assigning a greater chance to a hike than to no change, but there remains substantial uncertainty heading into the September meeting.
Bitcoin and Gold Feel the Immediate Pressure
Warsh’s comments initially pressured risk assets. Bitcoin fell roughly 3% following the speech, dropping below $77,000 after an earlier rally had taken the cryptocurrency from around $63,000 to above $80,000 during August.
Gold also moved lower, while the U.S. dollar and Treasury yields gained as markets reassessed the outlook for monetary policy. The reaction reflected the traditional relationship between tighter monetary policy expectations and financial assets sensitive to liquidity conditions.
The key question for crypto investors is whether the market is moving toward a sustained tightening cycle or simply repricing the possibility of one September move. Those scenarios can produce very different effects on Bitcoin and other risk assets.
Analysts Remain Divided on What a Hike Would Mean
Some market observers have pushed back against the idea that a September increase would necessarily represent the beginning of aggressive monetary tightening.
Robin Brooks, a senior fellow at the Brookings Institution and former chief economist at the Institute of International Finance, argued that a possible hike could instead be aimed at stabilizing the Treasury market and reinforcing confidence in the Fed’s inflation-fighting credibility.
Under that interpretation, the policy move would have a different objective from a traditional tightening cycle. Rather than attempting to suppress economic activity broadly, it could be used to influence longer-term borrowing costs and investor expectations.
Other market participants remain more cautious. Barclays, for example, shifted its forecast to two additional 25-basis-point hikes in 2026, one in September and another in December, following Warsh’s remarks.
Inflation and Jobs Data Will Decide the Next Move
The market’s current probability is only a snapshot. The Fed's September decision will depend on incoming economic information, particularly inflation and employment data.
Warsh said the labor market remains relatively stable, with unemployment at 4.1%, while describing inflation as the more concerning side of the Fed’s dual mandate. He also said financial conditions do not currently appear broadly restrictive.
That leaves upcoming economic releases especially important. A meaningful decline in inflation could reduce pressure for another rate increase, while evidence of persistent price growth could strengthen the case for tighter policy.
What the Fed Debate Means for Crypto
For Bitcoin and gold, the immediate focus is no longer simply whether the Fed will cut rates. Markets are now weighing whether policymakers could move in the opposite direction.
A September hike would increase borrowing costs and could tighten financial conditions, potentially creating additional pressure on liquidity-sensitive assets. But with market pricing still around the 60% level, the outcome remains uncertain rather than predetermined.
The broader takeaway is that Warsh has changed the conversation around September policy, but he has not provided a guaranteed path for rates. Until more inflation and employment data arrive, Bitcoin, gold, Treasury yields and the dollar are likely to remain sensitive to changes in the market’s expectations for the Federal Reserve.
