#美联储利率决议倒计时 #每周来晒 Written before the rate decision: No hike is highly likely tonight, but the market is waiting for one other sentence

At 2 a.m. Beijing time on October 29, the Federal Reserve will announce its October rate decision. Half an hour later, Fed Chair Warsh will hold a press conference.
Market expectations are now highly concentrated. The CME FedWatch tool shows the probability of rates remaining unchanged at this meeting is over 90%, while the probability of a 25-basis-point hike is below 10%. The Fed just hiked in September, raising the federal funds target range to 3.75%–4.00%. Moving again after just one month would be unusual. So tonight's real focus is not the interest rate figure, which is highly likely to remain unchanged.

Why is a widely expected rate hold still a big deal!
In theory, an event priced in at over 90% should not have much of an impact.
But this time is different, for three reasons.
First, this is the first meeting since the September hike. The market needs to determine whether that hike was a "one-off adjustment" or "the start of a new tightening cycle." These two characterizations imply completely different future paths.
Second, this meeting will not release a new Summary of Economic Projections or update the dot plot. Without this written guidance, all the information has to be gleaned from the statement's wording and the Q&A at the press conference. The lower the information density, the more valuable marginal changes in wording become.
Third, the Fed is not internally at ease. September's hike was unanimously approved, but many observers expect that if the Fed holds steady this month, two or three dissenting votes could emerge among the 12 voting members. Cleveland Fed's Hammack and Dallas Fed's Logan are considered the most likely to vote for an immediate hike. Dissenting votes would not change the decision itself, but they would send a signal: policymakers still have no consensus on whether current rates are restrictive enough.

Inflation is proving slower to extinguish than expected
To understand tonight's dilemma, start with the data.
U.S. CPI rose 3.7% year over year in September, with energy prices the main driver. More importantly, core CPI, which excludes food and energy, rose 2.6% year over year, not only significantly above the 2% target but also up 0.3 percentage points from August. This rebound is crucial: it shows price pressures are not confined to energy and have begun spreading to a broader range of goods and services.
CITIC Securities' view is that September core inflation was again elevated month over month, with price increases spanning a wide range of categories, and inflation is not falling toward the target quickly enough. Meanwhile, two other parts of the market are sending conflicting signals. The housing market is under pressure: mortgage rates are above 7%, transactions are shrinking, and developers have little appetite to invest.
The labor market, meanwhile, is in a strange stalemate. Layoffs are at historic lows; companies are not letting workers go, but they are not hiring much either. People who are unemployed are finding it increasingly difficult to find work. This "neither laying off nor hiring" state is neither overheating nor recession. On one side, inflation refuses to come down; on the other, rate-sensitive sectors are already feeling the pain. This is the Fed's predicament tonight.

Three scenarios, three exchange-rate reactions
Although the mainstream expectation is that rates will remain unchanged, there are different ways for rates to "stay unchanged." Breaking down the possibilities, there are roughly three scenarios.
Scenario 1: Rates hold, with hawkish wording.
This is currently the most likely scenario. Rates remain unchanged, but the statement and press conference emphasize that inflation risks remain, leaving the door open to a December hike. For the dollar, this usually means higher short-term rate expectations, supporting the dollar. The yuan may come under some pressure, but the impact will be limited because the market has already priced in most of this.
Scenario 2: Rates hold, with neutral wording.
If the statement downplays the need for "further tightening" and focuses on "watching the data," the dollar may weaken slightly. In this case, the yuan could appreciate passively. But note that this appreciation would come from a "weaker dollar," not from a "stronger yuan"—the two are not equivalent.
Scenario 3: An unexpected hike.
The probability is below 10%, but not zero. Matthew Martin of Oxford Economics expects the Fed to hike in both October and December, citing concerns about price increases spreading. If the Fed does hike, the dollar will strengthen rapidly, and the yuan may give back some of its gains in the short term. But given that the market has priced in only a single-digit probability, this shock is more likely to be a pulse than a trend.
The first two scenarios together have a probability of over 90%. So tonight's exchange-rate fluctuations are unlikely to be "directional"; they are more likely to be about "timing."

More data will follow the rate meeting
One detail is easy to overlook: after the decision is announced, the U.S. will also release its advance estimate of third-quarter GDP and September's Personal Consumption Expenditures price index. This means the policy expectations formed at the press conference could be revised just a few hours later by new data. If growth remains resilient and core prices continue to run hot, expectations for a December hike will strengthen; if the data weaken, the market will have to reassess the impact of tightening on employment and demand.

Tonight's decision will most likely be a "hold." But "no change" does not mean "nothing is happening." The fine-tuning of the wording, the number of dissenting votes, and the tone of the press conference—these details together make up the information the market really needs to read. For exchange rates, these details determine the timing, not the direction. After all, what is often more important than exchange-rate fluctuations are the arrangements already made before the decision.
