EUR/USD recovered some of its losses from the session peak just above 1.1150 as the Fed's statement lifted the pair. It remains below that peak but is trading in the upper half of Wednesday's range. With the Fed leaving rates unchanged, Thursday's European Central Bank (ECB) decision offers the final opportunity this week to alter the interest-rate differential driving EUR/USD. The ECB is also expected to keep rates steady.

The interest-rate differential has remained at 1.25-1.50 percentage points since mid-September, shaping trading in EUR/USD. On 10 September, the ECB approved its second increase this year, taking the deposit rate to 2.50%. That increase became effective on 16 September, when the Fed moved to 3.75%-4.00%. Neither central bank has changed rates since.
An unchanged rate on Thursday, followed by an increase in December, is the view held by most economists on the ECB. Before the Fed's decision, traders had assigned roughly an 80% probability to a Fed hike in December as well. Should each central bank raise rates by a quarter-point, the differential influencing EUR/USD would close the year at exactly the level in place since 16 September.
Growth figures from both sides of EUR/USD's interest-rate differential will be available before the weekend. Thursday's releases at 12:30 GMT comprise September's Personal Consumption Expenditures Price Index (PCE) and US third-quarter Gross Domestic Product (GDP). The ECB announces its decision at 13:15 GMT, followed by President Lagarde's press conference at 13:45 GMT. On Friday, the euro area's initial third-quarter GDP estimate is scheduled for 10:00 GMT.
Before the ECB's decision, the final word on US rates comes from Fed Chair Warsh, who takes questions at 18:30 GMT on Wednesday. Warsh said on 16 October that stronger inflation had not altered his assessment of the economy. Any further comments on December would feed into EUR/USD through the US side of the rate differential.
Intraday momentum was already oversold when the decision candle formed. Earlier, EUR/USD had fallen from its opening level to a session low just above 1.1100 before recovering. In the candles preceding the statement, the pair surrendered almost half of that rebound.

Responsibility for US monetary policy rests with the Federal Reserve (Fed), whose dual mandate is price stability and full employment. Adjusting interest rates is its main means of pursuing these objectives. If prices climb too rapidly and inflation exceeds its 2% target, the Fed increases interest rates. Higher borrowing costs across the economy make the US more attractive to international investors seeking a place for their funds, strengthening the US Dollar (USD). Conversely, inflation below 2% or an excessively high unemployment rate may prompt the Fed to cut interest rates to stimulate borrowing, putting pressure on the dollar.
Economic conditions are reviewed and monetary policy decisions taken by the Federal Open Market Committee (FOMC) at the Federal Reserve's (Fed) eight policy meetings each year. Twelve Fed officials participate: 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. Those four positions rotate, with each president serving a one-year term.
A substantial expansion in credit flowing through a stalled financial system is the aim of Quantitative Easing (QE), a policy the Federal Reserve may adopt in extreme circumstances. Used in crises or periods of exceptionally low inflation, this unconventional measure was the Fed's preferred response during the Great Financial Crisis in 2008. Under QE, the Fed prints additional Dollars to purchase high-grade bonds from financial institutions. The policy generally weakens the US Dollar.
Usually supportive of the US Dollar's value, Quantitative Tightening (QT) reverses QE. The Federal Reserve ceases bond purchases from financial institutions and, as bonds in its portfolio mature, does not use the repaid principal to buy new bonds.
