TOKYO, Dec 1 (Reuters) - The dollar steadied against the yen on Friday, losing steam after rising to a 10-day high, as the market endured the wait for a vote on a U.S. tax reform bill.
The greenback stretched overnight gains and initially climbed to 112.690 yen, its highest since Nov. 21, as Wall Street rallied and Treasury yields spiked after U.S. tax reform plans were seen progressing towards legislative approval following an endorsement by Senator John McCain.
But the dollar was last at 112.510 yen, unchanged on the day, after it was decided that the U.S. Senate will not vote on the tax bill late on Thursday night U.S. time but would continue the debate on Friday.
"That fact that the vote did not take place on Thursday evening shows that there are still some kinks to be ironed out, but it is not like the deliberations have fallen through," said Yukio Ishizuki, senior currency strategist at Daiwa Securities.
"The dollar stalled along with the slip in equities, but equities were due for a minor correction after yesterday's surge."
S&P mini futures were last down 0.3 percent after Wall Street shares soared to record highs on Thursday.
The dollar index against a basket of six major currencies was 0.1 percent lower at 92.956 but poised to eke out a 0.2 percent gain for the week, during which it managed to pull away from a two-month low of 92.496.
The euro was little changed at $1.1908 after gaining about 0.5 percent the previous day.
The common currency, which reached a two-month top of $1.1961 on Monday following upbeat German data and pressured the dollar, was still on track for a 0.3 percent weekly loss after a volatile week.
The pound was a shade higher at $1.3534 after surging 0.9 percent overnight when it set a two-month high of $1.3549.
"Hopes in the euro zone appear strong that ongoing talks in Germany would lead to a coalition government, while in Britain there is growing optimism over Brexit negotiations progressing," said Masafumi Yamamoto, chief forex strategist at Mizuho Securities in Tokyo.
"Short-term investor pessimism towards the euro zone and Britain is receding, supporting the euro and pound against the dollar. But dollar/yen maintains a high correlation with U.S. yields, which explains the latest rise by the pair," Yamamoto said regarding the dollar's rise early on Friday.
