The dollar fell on Wednesday, hitting its lowest level since October against a basket of major currencies and marking its worst one-day performance in five months.
The release of minutes from the Federal Reserve's most recent policy meeting, weak U.S. data and technical trading aligned to send the dollar tumbling against both safe-haven and risky currencies.
The dollar plumbed its lows of the day after the release of the Fed's November meeting minutes showed policymakers may be starting to question a December interest rate increase as inflation has remained subdued.
The dollar index, which tracks the greenback against six major currencies, fell 0.72 percent, to 93.28, its lowest since Oct. 20.
Against the yen, the dollar fell more than 1 percent, touching its lowest since late September. It was the dollar's largest single-day fall against the yen since May.
The greenback fell more than 1 percent against a host of currencies during the session. It slipped 1 percent versus the Swiss franc, which investors typically seek in times of market uncertainty, as well as currencies including the Brazilian real, South African rand and Russian rouble, which are generally sought in risk-on trading.
The euro rose to a five-day high against the dollar of $1.1817.
New orders for U.S.-made capital goods unexpectedly fell in October after three straight months of strong gains and a measure of goods orders that strips out volatile components had its biggest drop since September 2016.
The University of Michigan's consumer sentiment report also showed a decline in expectations for long-term inflation.
While the data may have sparked selling, analysts agreed the dollar's strong declines were largely a result of low volatility in the market a day before the U.S. Thanksgiving holiday and currencies touching important levels, prompting automatic trades.
"This is a bit of a technical retreat in the dollar, not really a fundamental one," said Thierry Albert Wizman, global interest rates and currencies strategist at Macquarie Limited.
BMO's global head of foreign exchange strategy, Greg Anderson, said the dollar's weakness against riskier currencies and safe havens suggested the U.S. currency's recent resurgence is ending.
"We should be back to U.S. dollar weakness a little bit into December and even more so early next year," Anderson said. "That's just what happens when you have strong global growth is you get U.S. dollar weakness."
