The Fed kept rates at 3.75%-4.00% on Wednesday. Two officials voted for a hike, leaving December as this year's final opportunity to deliver the increase most officials had projected. In the five-minute bar covering the statement, the Dollar Index slipped to just above 101.90 before rebounding within the same bar. It did not reach the pre-decision session low near 101.85 and now trades just below 102.00.

A quarter-point increase was backed by Fed Governor Cook and Cleveland Fed President Hammack. MUFG had previously said this type of dissent would reinforce expectations of a December hike. While describing inflation as still elevated, the statement offers no timetable for the next change. It says only that further information will help determine the policy stance. Following the release, the Dollar Index remained within its pre-decision trading range.
At least one further hike this year featured in the September projections of 16 of the Fed's 18 officials; four anticipated two. With October now past, December is the sole remaining meeting for either outcome. Delivering two hikes at that meeting would require a half-point increase, a step the Fed last took in December 2022. Before the decision, traders priced the probability of a December hike at near 80%, aligning with the 16 officials rather than the four.
Thursday's 12:30 GMT releases cover third-quarter Gross Domestic Product (GDP) and the September Personal Consumption Expenditures Price Index (PCE). These will be the first US data since the rate hold with implications for December. Also on Thursday, the European Central Bank (ECB) announces its decision at 13:15 GMT, followed by the Bank of Japan (BoJ) on Friday. Those decisions concern the Euro and Yen, which together account for about 71% of the index.
At 18:30 GMT on Wednesday, Fed Chair Warsh begins his press conference. Speaking in Bangkok on October 16, he said he does not pre-judge meetings. With two colleagues already favouring a hike, his responses on December will directly inform the pricing underpinning the Dollar Index.
Just above 102.15 marked the index's session high in the first half of Wednesday. It subsequently dropped to the session low, then retraced about half the decline ahead of the statement. Despite the rebound within the decision bar, the index remained below its opening level for the day. The advance into the announcement had pushed intraday momentum into overbought territory.

Responsibility for US monetary policy rests with the Federal Reserve (Fed). Price stability and full employment form its dual mandate, with interest-rate adjustments serving as its main policy tool. If prices rise too rapidly and inflation exceeds the Fed’s 2% target, the central bank increases interest rates. Higher borrowing costs across the economy make the US more attractive to international investors seeking somewhere to place their funds, strengthening the US Dollar (USD). Conversely, inflation below 2% or an excessively high unemployment rate may prompt the Fed to cut rates. The aim is to stimulate borrowing, but the move puts pressure on the Greenback.
At eight meetings each year, the Federal Reserve (Fed) reviews policy through the Federal Open Market Committee (FOMC). The committee evaluates economic conditions and decides monetary policy. Twelve Fed officials attend the FOMC: all seven members of the Board of Governors, the president of the Federal Reserve Bank of New York and four of the other eleven regional Reserve Bank presidents. The latter four serve rotating one-year terms.
To restore a substantial flow of credit through a stalled financial system, the Federal Reserve may turn to Quantitative Easing (QE) in extreme circumstances. This unconventional measure is used in crises or when inflation is exceptionally low. During the Great Financial Crisis in 2008, it was the Fed’s preferred policy response. Under QE, the Fed prints additional Dollars to purchase high-grade bonds from financial institutions. The US Dollar typically weakens as a result.
By reversing QE, quantitative tightening (QT) generally supports the US Dollar's value. Under QT, the Federal Reserve ceases bond purchases from financial institutions. It also stops reinvesting principal received when its existing bonds mature into new bond purchases.
