SINGAPORE, April 6 (Reuters) - Oil prices rose while

stocks were mixed on Monday after U.S. President Donald Trump

warned of "hell" for Iran unless it reopens the Strait of Hormuz

by his self-imposed deadline, but a report of a push for a

ceasefire appeared to ease some nerves.

Trump's repeated threats to destroy civilian infrastructure

including power plants and bridges if the vital waterway is not

open by Tuesday have put traders on edge for reciprocal attacks

by Iran on targets in the Gulf states.

With liquidity thin as many countries around the region

observed Easter Monday holidays, S&P 500 e-mini futures

fluctuated between gains and losses, down 0.1%, while MSCI's

broadest index of Asia-Pacific shares outside Japan

was up 0.3%. The Nikkei 225 rose 1.3%,

as South Korea's Kospi advanced 0.9%.

Investors took some confidence after Axios reported that the

U.S., Iran and a group of regional mediators are discussing the

terms for a potential 45-day ceasefire that could lead to a

permanent end to the war, citing four U.S., Israeli and regional

sources with knowledge of the talks.

Brent crude futures opened higher before paring

gains, rising 0.5% to $109.55 a barrel on the potential supply

disruption.

"The markets are obviously nervous," said Sim Moh Siong,

currency strategist at OCBC in Singapore. "We've seen many of

these deadlines being pushed out, and it's difficult to tell to

what extent this deadline is going to stick, or will it be

pushed out too," he added.

"There was a lot of de-escalation hope, but some of this

hope has fizzed out over the weekend in the ramping up of

threats to blow up Iranian power plants and bridges."

Markets looked through an agreement on Sunday by members of

the OPEC+ group to raise its output quotas by 206,000 barrels

per day for May, as several major oil producers behind the

Strait of Hormuz have sustained damage to oil production

facilities and transport infrastructure since the war started.

On Friday, the U.S. jobs report showed employment growth

rebounded more than expected in March, with a 178,000 increase

in nonfarm payrolls representing the biggest increase in more

than a year. The unemployment rate fell to 4.3% from 4.4%, as

people dropped out of the workforce.

The data complicates the picture for the Federal Reserve,

which will next decide on monetary policy at a two-day meeting

ending on April 29. However, swaps pricing indicates the market

is expecting no moves at all from the U.S. central bank until

September 2027, according to the CME Group's Fedwatch tool.

The U.S. dollar index, which measures the greenback's

strength against a basket of six currencies, was down 0.1% at

100.15. The yield on the U.S. 10-year Treasury bond was up 0.8

basis point at 4.352%.

In Tokyo, the yield on the Japanese government bond set a

fresh record for the 21st century on concerns about rising

inflation. The yield on the notes was up 3.0 basis points at

2.41%, the highest since February 1999. Against the yen,

the U.S. dollar was flat at 159.555 yen.

Gold slid 0.6% to $4,646.27. In cryptocurrencies,

bitcoin was up 2.2% at $69,120.37, while ether

advanced 3.0% to $2,130.78.
