Bond traders are on edge ahead of the Federal Reserve's policy decision (early Thursday morning Beijing time). While most expect policymakers to keep interest rates unchanged, several prominent Wall Street firms are betting on a rate hike at Warsh's second meeting. This would signal a "new system" for the Fed: Warsh wants to avoid signaling interest rates to the market in advance as his predecessors did. A rate hike would solidify Warsh's credibility in combating inflation, but it also means bigger market surprises. Demand for hedging against a surprise rate hike this week has hit a record high, reflecting traders' growing anxiety.

The voices advocating for interest rate hikes are growing stronger.

Citadel Securities' head of macro strategy unexpectedly shifted its baseline scenario to a rate hike this week, stating that this would "completely end the era of forward guidance" and highlight the Fed's independence. Wrightson ICAP's chief economist stated that the Fed has no compelling reason not to raise rates. PGIM's global head of bonds and chief investment strategist believes the market may be underestimating the likelihood of a rate hike on Wednesday: "He (Wash) really paved the way for a rate hike, and delaying the decision now increases the probability of a 50-basis-point hike in September." Bond market veterans go further, arguing that the Fed should "rip off the band-aid" and raise rates by 50 basis points—a move that would both lend credibility to its ability to combat inflation and counter pressure from President Trump to lower borrowing costs. "A 50-basis-point rate hike shows that a new sheriff has arrived in town, one who is not subject to the president."

The market is completely in the dark.

Uncertainty is driving traders to heavily bet on this week's outcome—hedging demand is at a record high. Open interest in August federal funds futures contracts reached 909,714 contracts on Friday, surpassing the previous record set by the October 2024 contract, and further increased to 967,136 contracts on Monday. Since taking office in May, Warsh has vowed to radically reform the Fed's communication style—no more prematurely announcing intentions and restoring price stability. At his first press conference last month, he declined to offer specific insights into the future path of interest rates. Recent rate repricing primarily reflects the rebound in energy prices following the renewed escalation of the US-Iran conflict, as well as the resilience of the labor market. Despite a rebound in Treasury bonds on Tuesday due to falling oil prices, traders are still fully pricing in a 25-basis-point rate hike in September and nearly 50 basis points in cumulative hikes since March. "The market is pricing in very real rate hike risks, and investors are still trying to understand how the Fed will operate under Warsh's leadership," noted the head of US interest rate strategy at Bank of America.

Disagreements and Uncertainties

The head of U.S. interest rate strategy at BMO Capital Markets noted that since 2015, traders' error in predicting the Fed's final interest rate decision has averaged 2.4 basis points the day before the decision. "The market is prepared for a more dramatic knee-jerk reaction to the FOMC decision than usual." UBS's chief U.S. economist stated that he "has never felt so uncertain about the upcoming Fed interest rate decision in 20 years—since Bernanke became Fed chairman." Warsh's lack of historical precedent and recent internal divisions among Fed officials further cloud the outlook. He did not rule out a scenario where Warsh himself cast the deciding vote: "Given his current ability to push the committee's median, he will determine the policy direction in the next few meetings, and we have absolutely no idea how Warsh views monetary policy."

Two scenarios for the US dollar index

The high level of uncertainty ahead of the Federal Reserve's policy decision is directly influencing the dollar index. Traders' bets on a possible surprise rate hike during Warsh's tenure have intensified, pushing up expectations for US Treasury yields, widening the US-Europe interest rate differential, and supporting a short-term stronger dollar. Record open interest in federal funds futures in August reflects significant market hedging against rate hike risks; this tension often increases dollar index volatility before decisions. If the Fed raises rates decisively on Wednesday, it will strengthen its resolve to combat inflation under the "new regime," quickly boosting the dollar index; if it holds steady, previously priced-in rate hike expectations will be reversed, and the dollar may weaken rapidly. While falling energy prices have briefly supported Treasury bonds, the resilience of the labor market and the shadow of the US-Iran conflict continue to obscure the interest rate path, causing the dollar index to exhibit "news-driven" fluctuations. In short, Warsh's decision to end forward guidance amplifies policy surprises, making the dollar index far more sensitive to this decision than ever before, and its movement will be highly dependent on the final interest rate decision and the speed of market repricing.

The FOMC has officially entered the "Wash era," where uncertainty itself has become the greatest certainty.

The FOMC is facing its most uncertain interest rate decision in recent years. Warsh's "ambiguity strategy" means the market can no longer rely on the Fed's forward guidance to predict policy paths as it has in the past—the probability of a rate hike and holding rates steady is roughly 30% and 70% respectively, but this allocation itself reflects uncertainty. Citadel Securities' unexpected reversal, PGIM's rate hike warning, and record hedging demand all confirm one fact: the Fed's communication mechanism has undergone a fundamental shift. Regardless of the final outcome, the market will face rapid repricing. For traders, future FOMC meetings may no longer be a "known event," but a genuine "risk event."
