Federal Reserve chair Kevin Warsh is entering another difficult policy decision as rising Treasury yields, elevated oil prices and persistent inflation concerns push financial markets towards expectations of another US interest-rate increase.
Traders have sharply increased their expectations for higher Fed interest rates at the Federal Open Market Committee’s October meeting. CME FedWatch, which derives probabilities from Fed Funds futures pricing, showed the probability of an October increase above 70% on September 23. The shift comes after the Fed increased its target rate by 25 basis points at its September meeting.
Treasury Yields Raise the Cost of Standing Still
The pressure is particularly visible in the US government bond market. The 10-year Treasury yield reached its highest level since 2007 on September 24 before ending the session around 5.10%, while the 30-year yield touched 5.44%, its highest level since 2004.
The move reflects growing concern that inflation could remain difficult to contain and force monetary policy to stay restrictive for longer. Higher Treasury yields also tighten financial conditions independently of any Fed decision, because government borrowing rates serve as important benchmarks across mortgages, corporate debt and other parts of the credit market.
Energy has become another major complication. Brent crude briefly moved above $100 per barrel this week as investors followed diplomatic efforts involving the United States and Iran. Reuters reported earlier in the week that Brent had fallen to $100.34 amid hopes for renewed diplomacy and signs of recovering Saudi exports, highlighting how quickly expectations around Middle East supply can move the market.
Iran has indicated a willingness to pursue negotiations under certain conditions. Reuters reported that Iranian officials had given their delegation at the United Nations General Assembly authority to pursue diplomatic discussions, while US President Donald Trump has publicly maintained a much harder position towards Tehran.
Oil Is Turning Into a Monetary Policy Problem
The importance of oil extends well beyond energy markets. A sustained increase in crude prices can feed into transportation, manufacturing and household costs, complicating the Fed’s attempt to bring inflation back towards its target.
That connection helps explain why investors have become more sensitive to developments in the Middle East. Disruption around major export routes has already forced producers to use more expensive alternatives to keep crude moving. Reuters reported that ship-to-ship transfers near Oman reached about 2.5 million barrels a day in September, up from 1.4 million in August, while freight costs for some shipments have climbed sharply.
For investors, the significance of the current bond sell-off is that monetary tightening is no longer confined to decisions made inside the Fed. When longer-term Treasury yields rise substantially, financing conditions can become more restrictive before policymakers change the benchmark rate again.
That creates a difficult feedback loop for the central bank. Strong economic activity may give policymakers more room to increase rates without immediately damaging growth, but persistently expensive energy could keep inflation elevated even as higher borrowing costs begin weighing on rate-sensitive sectors.
The Fed’s September decision has already altered expectations. CME Group said after the meeting that futures markets had moved towards pricing two additional 25-basis-point increases during the remainder of 2026, compared with one previously.
Warsh Must Balance Inflation Risk With Fed Credibility
Warsh also faces political pressure from the White House. President Trump has argued for lower borrowing costs, creating a clear policy disagreement with a central bank confronting renewed inflation risks.
For markets, however, the next decision will be judged primarily against incoming inflation, employment and energy data. The next scheduled FOMC rate decision is October 28, according to CME Group’s economic calendar.
The most important signal before then may come from whether Treasury yields and oil prices remain elevated. If both continue higher, financial conditions could tighten further while inflation concerns remain unresolved. If energy prices retreat as diplomacy progresses, policymakers would have more room to assess whether September’s increase has already done enough.
Either way, October is becoming a significant test of how Warsh’s Fed responds when market expectations, inflation risks and political pressure point in different directions.
