* Oil prices sink amid rising inventories

NEW YORK, Dec 18 (Reuters) - Global equity markets turned lower late on Tuesday as nervous investors awaited indications whether the U.S. Federal Reserve will be able to raise interest rates much further amid turbulent markets and a weakening outlook for the global economy.
Energy stocks weighed on the U.S. market as oil price declines deepened.
Steep drops in equity markets over the last two months have sapped investor confidence, spurring fund managers to predict global growth to weaken over the next 12 months, the worst outlook in a decade, Bank of America Merrill Lynch’s December investor survey showed.
MSCI’s world stock index fell 0.5 percent. The index is down 10 percent this year and is set for its worst year in a decade.
The Dow Jones Industrial Average rose 68.72 points, or 0.29 percent, to 23,661.7, the S&P 500 lost 6.26 points, or 0.25 percent, to 2,539.68 and the Nasdaq Composite added 8.57 points, or 0.13 percent, to 6,762.30.
The benchmark S&P 500 index began the trading session almost 8 percent lower for December.
“We’re facing the biggest December fall in U.S. stocks since 1931 and this is striking and worrying at the same time,” said Chris Bailey, European strategist at international financial services firm Raymond James. “We are at a regime shift moment, and the debate is how big that regime shift will be.”
A speech by Chinese President Xi Jinping, which investors had hoped could lift morale, had little impact after he offered no specific support measures for the economy. Chinese shares fell over 1 percent . Japan’s Nikkei lost 1.8 percent.
Adding to the gloomy mood, the German Ifo economic institute’s business climate index fell for the fourth month in a row to its lowest level in more than two years and Japan’s government revised down its economic growth forecasts.
On Monday, U.S. President Donald Trump and his top trade adviser stepped up their criticism of the Fed’s monetary tightening, raising investor anxiety.
Benchmark 10-year notes last rose 10/32 in price to yield 2.8228 percent, from 2.857 percent late on Monday.
U.S. crude futures settled down 7.3 percent while Brent settled down 5.6 percent, weakening for a third consecutive session on reports of swelling inventories and forecasts of record U.S. and Russian output.
The dollar extended its declines against major currencies ahead of the Fed meeting. The dollar index, tracking it against six major peers, was flat, with the euro up 0.11 percent to $1.1358.
