TOKYO, Feb 8 (Reuters) - Global share markets remained shaky on Thursday as U.S. bond yields crept up towards four-year highs after U.S. congressional leaders reached a two-year budget deal to raise government spending by almost $300 billion.
While the deal was a rare display of bipartisanship that should stave off a government shutdown, it looks set to widen the U.S. federal deficit further, and could fan inflation worries and prompt the Fed to raise interest rates faster.
European shares are expected to decline, with Germany's Dax futures falling 0.5 percent, and France's Cac futures and Britain's FTSE futures shedding 0.7 percent.
"The scale of increase in spending was much larger than what markets were expecting just a few months ago. It will have as big impacts as tax cuts. Since the markets haven't priced this in yet, U.S. bonds could be sold for another week or so," said Tomoaki Shishido, fixed income analyst at Nomura Securities.
Combined with an expected economic boost from President Donald Trump's planned tax cuts, the increased deficit spending could overheat already strong U.S. growth and accelerate inflation to levels not seen over a decade.
Such fears drove the 10-year U.S. Treasuries yield back up to 2.840 percent, near Monday's four-year peak of 2.885 percent.
The Senate and the House were both expected to vote on the proposed deal on Thursday, amid some opposition on both sides of the aisle.

U.S. stocks ran out of steam on Wednesday after an early surge, with the S&P 500 ending down 0.50 percent and the Nasdaq Composite losing 0.9 percent.
The Cboe Volatility Index, known as the VIX and often seen as investors' fear gauge, fell 2.3 points to 27.73, but that was still more than twice the levels generally seen in the past few months.
Andrew Milligan, Head of Global Strategy at Aberdeen Standard Investments, said in a note it was not a surprise to see a market correction after a long period of low volatility.
"This (low volatility) was aided by central bank QE policies continuing to inject sizeable amounts of liquidity into a wide range of financial assets, as well as the steady state of the global economy continuing to reassure investors," he said.
"All in all, the probability of a correction has increased over time, which creates a good opportunity for active investors, as long as long-term drivers remain positive."
