* Sterling recovers ground
* C$ edges higher vs U.S. dollar as oil prices rise (Updates prices, market activity; adds analyst's comments)
NEW YORK, Nov 6 (Reuters) - The dollar stumbled against a basket of currencies on Monday, giving up some recent gains, as uncertainties related to proposed U.S. tax revisions and the future composition of the Federal Open Market Committee discouraged traders from bidding the greenback higher.
The dollar index, which tracks the greenback against six major currencies, was down 0.19 percent at 94.764. The index has risen nearly 3 percent since mid-September.
The dollar was 0.31 percent lower against the Japanese yen, and the euro was down 0.03 percent against the greenback.
"The dollar rally has kind of stalled here a little bit," said Minh Trang, senior currency trader at Silicon Valley Bank in Santa Clara, California.
Uncertainty around the proposed U.S. tax reform and lack of clarity on what the FOMC is going to look like going forward, are among the reasons keeping investors from turning more bullish on the dollar, Trang said.
House Republicans last week unveiled the first draft of legislation that, if enacted, would revamp the U.S. tax system the most since the 1980s.
The House tax-writing panel, the Ways and Means Committee, begins revising the bill on Monday, with tweaks and some more substantial changes expected to a number of individual and corporate tax proposals.
On Monday, the Federal Reserve Bank of New York confirmed that William Dudley, among the most influential monetary policymakers throughout the financial crisis and its aftermath, expects to retire by mid-2018.
That raised another question over leadership at the U.S. central bank less than a week after President Donald Trump chose a new Fed chief.
"Until we see a little bit more certainty the dollar is a little bit gun-shy at this point," Trang said.
Sterling rose 0.73 percent against the dollar, rebounding from a one-month low hit after the Bank of England raised its lending rate for the first time in a decade last Thursday but forecast only gradual tightening ahead.
The Canadian dollar was slightly stronger against its U.S. counterpart. Prices of oil, one of Canada's major exports, reached their highest since July 2015 as Saudi Arabia's crown prince cemented his power over the weekend through an anti-corruption crackdown.
Latin American currencies rebounded from the previous week's selloff as rising prices of basic products drove investors to hunt for bargains. The greenback slipped 0.82 percent against the Mexican peso.
