The US Dollar Index is trading in a tight range near 101.35 during the Asian session on Wednesday, as the market holds its breath ahead of the FOMC decision.

According to the CME FedWatch Tool, the probability of the Fed holding rates steady in July stands at 69.5%, while the odds of a 25-basis-point rate hike are 30.5%. An escalation in the Middle East has pushed oil prices higher, strengthening the hawkish camp's concerns about "energy prices feeding into sticky inflation." Meanwhile, the cooler June CPI figures have given doves some breathing room.

The Fed's Communication Style Is Undergoing a Fundamental Shift

In recent years, the Federal Reserve has typically pre-communicated its policy signals to the market. However, Chair Warsh aims to return the Fed to a more ambiguous era of communication with the market—reminiscent of the style of former Chairman Alan Greenspan. Warsh has repeatedly stated that he wants "good family debate" during rate-setting meetings, and this week he is likely to get his wish. At the June meeting, half of the officials expected a rate hike this year, while the other half believed rates could be held steady. Warsh has not revealed his own stance, suggesting he could push the central bank in either direction. The June meeting minutes showed that if inflation subsides, most officials prefer to keep rates unchanged or eventually cut them; however, if inflation remains elevated due to a stable job market, strong AI demand, Middle East conflicts, and tariff effects, nearly all officials see a need to raise rates.

Internal Divergence of Views

Several Fed officials, including Governors Cook, Waller, and Jefferson, have signaled they are comfortable with holding rates steady in July, but would consider a hike if inflation doesn't cool further. Dallas Fed President Lorie Logan, however, believes it is time to act, stating in mid-July that inflation is "persistently too high for too long" and that "a modest increase in interest rates would better balance the outlook and risks at this point." New York Fed President John Williams, on the other hand, believes inflation has peaked and advocates for holding rates steady rather than hiking, citing falling energy and housing prices. He says there are "encouraging reasons to expect inflation has peaked and will gradually recede in the coming quarters."

The Case for Holding Steady

The rationale for holding rates steady depends on whether inflation continues to decline in the coming months. Core CPI fell from 2.9% to 2.6% in June, and a nearly 10% drop in gasoline prices pulled the headline inflation rate down from 4.2% to 3.5%. However, Tilly, chief economist at Wilmington Trust, notes that while there is a risk of the war's impact on energy costs spilling over into core inflation, "it hasn't happened yet." He believes the economy is strong enough to avoid a recession but not strong enough to push inflation higher—if consumers cut spending due to rising oil prices, high inflation would come entirely from gasoline prices. He expects the Fed will not hike this week and that the Fed's next move will be a cut in September, followed by another reduction. "If they hike in July, I think they'll have to reverse it within six months."

The Case for a Rate Hike

The other camp of officials is uncertain about the direction of inflation. Former Cleveland Fed President Loretta Mester stated that if inflation doesn't start to fall, or even re-accelerates due to oil price uncertainty, "they would have to seriously consider that re-calibrating policy might be the right thing to do." George pointed out that energy prices will remain high, and a new round of tariffs could trigger a second wave of price increases. "Inflation has been above target for over five years," George said. "The Chair has made a lot of hawkish statements about inflation, saying it's a choice—so how will he match that with action on current inflation?" Warsh has repeatedly said the Fed will achieve price stability but has offered no guidance on the rate path or how the central bank will achieve that goal. George believes: "Taking one step (a rate hike) might be enough to solidify inflation expectations, and then decide on further action based on how the economy evolves, because I know Warsh does expect supply-side relief to materialize at some point."

An Unexpected Rate Hike Is Not Impossible

The current FOMC faces its most uncertain rate decision in recent years. The CME FedWatch Tool shows a 69.5% probability of holding steady in July and a 30.5% probability of a hike. Warsh's "family debate" style makes the outcome of this meeting even harder to predict, and the internal split between hawks and doves means any result is possible. For traders, this week's FOMC is no longer a "known event" but a genuine "risk event"—whether it's a hike or a hold, the market will face a rapid repricing. As of 10:38 Beijing time on July 29, the US Dollar Index was at 101.34.
