GLOBAL MARKETS-Oil prices soar, and stocks end mixed in volatile trade

By Chris Prentice and Marc Jones

NEW YORK/LONDON, April 2 (Reuters) - Oil prices surged on Thursday and equities markets around the world were mixed in volatile trade as traders weighed conflicting developments and remarks related to the Iran war.

European shares trimmed losses, as some major Wall Street indexes and U.S. bond prices clawed back gains on news that Iran was drafting a protocol with Oman to monitor traffic in the Strait of Hormuz.

But world oil prices LCOc1 surged nearly 8% and U.S. crude soared more than 11% the day after U.S. President Donald Trump said in a prime-time address that the U.S. would hit Iran "extremely hard" in the coming weeks and "bring them back to the Stone Ages where they belong."

On Wall Street, stocks ended mixed in a choppy last trading day of the week ahead of the Good Friday holiday.

Gold prices fell as the U.S. dollar gained.

Government bond yields jumped on expectations that an inflation spike would force central banks to raise interest rates, or at least keep them on hold. GVD/EURUS/

The dollar index =USD, which measures the greenback against a basket of currencies including the yen and the euro, climbed 0.44%.

"Over the past 48 hours, Tehran and Washington have exchanged a cacophony of statements, some suggesting rising odds of de-escalation," BCA Research's Felix-Antoine Vezina-Poirier said. "Our GeoMacro strategists offer simple guidance for weighing volatile headlines: Stick to the facts. First, shipping through Hormuz has picked up over the past few days. Second, Iran is deliberately shifting away from GCC (Gulf Cooperation Council) targets toward Israeli ones."

WALL STREET POINTS LOWER

MSCI's gauge of stocks across the globe .MIWD00000PUS fell 0.35% to 993.18.

On Wall Street, the Dow Jones Industrial Average .DJI fell 0.13% to 46,504.67, the S&P 500 .SPX reversed course to gain 0.11% to 6,582.69 and the Nasdaq Composite .IXIC added 0.18% to 21,879.18.

In a closely watched address on Wednesday, Trump said U.S. attacks on Iran would be intensified over the next two to three weeks. That came just a day after he told Reuters the U.S. would be "out of Iran pretty quickly."

The pan-European STOXX 600 .STOXX index and Europe's broad FTSEurofirst 300 index .FTEU3 both lost 0.2%.

South Korea's Kospi index .KS11 slid 4.7%.

"The only thing that really matters is whether the Strait of Hormuz will open soon," said Prashant Newnaha, senior rates strategist at TD Securities.

Trump earlier said on Wednesday the U.S. did not need the key oil gateway.

Spot gold XAU= fell 1.85% to $4,669.05 an ounce and U.S. gold futures GCcv1 settled down 2.8% at $4,679.70.

India's central bank moved to ban trading of so-called non-deliverable forwards in an effort to halt the rupee's run of record lows. The move sent the currency up 2% INR=IN, although analysts questioned how long the rebound would last.

Brent futures LCOc1 rallied to end up 7.78% at $109.03 a barrel, as U.S. West Texas Intermediate CLc1 settled up 11.41% to $111.54.

"The fact that we can expect 2-3 more weeks of action, boots on the ground were not ruled out (during Trump's TV address) and that threats to hit infrastructure were reiterated, will put the market back on the defensive," Pictet Asset Management's Jon Withaar said.

The yield on benchmark U.S. 10-year notes US10YT=RR fell 1.6 basis point to 4.305%. The two-year note US2YT=RR yield, which typically moves in step with interest rate expectations for the Federal Reserve, was flat at 3.803%.

Euro zone benchmark Bund yields snapped a three-day decline and traders raised bets for interest-rate hikes. The yield on the benchmark German 10-year DE10YT=RR rose 0.1 basis points to 2.996%.
