NEW YORK, Dec 7 (Reuters) - A gauge of global stocks gained on Thursday, boosted by Wall Street, and the U.S. dollar touched a two-week high as risk appetite returned and investors braced for developments with U.S. policy and for a key U.S. jobs report due on Friday.
Longer-dated U.S. Treasury yields rose as increased risk appetite diminished the attractiveness of safe-haven U.S. government debt. Oil prices rebounded a day after hitting two-week lows.
A U.S. tax bill moving swiftly through Congress has influenced markets in the past month, with investors hoping that deep cuts to corporate tax rates will help further drive the record-setting run in equities.
The White House said on Thursday it was focusing on getting the lowest corporate tax rate possible in the legislation being considered on Capitol Hill.
“The focus is still on the tax bill," said Bucky Hellwig, senior vice president at BB&T Wealth Management in Birmingham, Alabama. "As the details are getting hammered out, I think investors are still buying into the news that it is coming and it will help profitability and business activity.”
Investors also kept an eye on U.S. negotiations over a spending package, amid some concern about a government shutdown.

The dollar index rose 0.18 percent to $93.78, with the euro down 0.2 percent to $1.1771.
"Tomorrow's jobs report will play a significant factor in keeping the (dollar) rally alive and heightening hopes for an early 2018 rate hike," said Lennon Sweeting, chief market strategist at XE in Toronto.
Bitcoin rocketed to a lifetime high just shy of $16,000 after climbing some 60 percent in just over a week, intensifying the debate about whether the cryptocurrency is in a bubble about to burst.
Investors favored selling longer-dated debt as the U.S. Treasury yield curve had compressed to its tightest in more than a decade earlier this week, while short-term Treasury yields were little changed.
Benchmark 10-year notes last fell 9/32 in price to yield 2.3599 percent, from 2.33 percent late on Wednesday.
