SYDNEY, June 12 (Reuters) - Asian stocks joined a global

rally on Friday on hopes a Middle East peace deal may finally

materialise, while the dollar and bond yields dropped and oil

prices fell to two-month lows, tempering inflation fears.

All eyes are on the hotly-awaited market debut of Elon

Musk's SpaceX, which has made history with the

biggest-ever initial public offering. The IPO raised a record

$75 billion, valuing the rocket and spacecraft manufacturer at

$1.77 trillion and making Musk the world's first trillionaire.

U.S. President Donald Trump said on Thursday that a peace

deal could be signed as soon as this weekend, hours after

threatening more strikes on Iran. He said negotiations with

Tehran had advanced to the highest levels of Iran's leadership

and had been approved by a broad coalition of regional powers.

Trump's remarks follow repeated bouts of optimism from the

president that have failed to yield a deal, keeping markets on

edge.

Nonetheless, "this does look perhaps a bit more tangible

than we have had," said Ray Attrill, head of FX strategy at

National Australia Bank.

"If we hear something from Iran that sounds positive, the

odds (of a peace deal) are clearly going to flip quite

dramatically."

The deal, if confirmed, would be the most significant

diplomatic breakthrough yet to end the three-month-old war,

which has sent global energy prices sharply higher. The European

Central Bank had to raise interest rates for the first time in

nearly three years on Thursday to nip war-driven inflation in

the bud.

Oil prices slumped to two-month lows on the news of an

agreement before trimming some of the losses. U.S. West Texas

Intermediate (WTI) crude futures were last down 1.2% to

$86.69 a barrel, on top of a 2.6% drop overnight. Brent

dropped 1.1% at $89.40 per barrel, having fallen nearly 3%

overnight.

MSCI's broadest index of Asia-Pacific shares outside Japan

jumped 3.2%, led by a 7.4% surge in South

Korea's KOSPI. Japan's Nikkei rose 2.7%.

China's blue-chip CSI300 rose 1%, while Hong

Kong's Hang Seng gained 1.3%.

Overnight, Wall Street rallied with the three major indexes

registering their biggest daily gains since April 8, when the

U.S. and Iran agreed to a temporary ceasefire. The Nasdaq jumped

2.5%, helped by expectations of a strong market debut for Musk's

SpaceX.

IG estimates the expected market cap of SpaceX at the close

of business on day 1 would be just over $2.4 trillion.

"It suggests that SpaceX's market cap ... will be about 35%

higher than the $1.78 trillion valuation set for the IPO," Tony

Sycamore, analyst at IG, said in a note. "This, in turn,

suggests the SpaceX share price will likely finish today

somewhere in the ~$175/$180 range."

Treasuries held onto gains as hopes of a peace deal in the

Gulf led markets to trim bets of a rate hike from the Federal

Reserve this year. Pricing for a hike in October has come down

to 36% from 51%.

Two-year Treasury yields were steady at 4.074% on

Friday, having slumped 6 basis points (bps) overnight. Benchmark

10-year Treasury yields held at 4.4710%, after

falling almost 8 bps overnight.

The dollar stabilised after overnight losses. It rose 0.2%

to 160.20 yen, after retreating 0.4% in the prior

session. Traders are still on high alert for intervention from

Japanese authorities as the yen stays close to the 160 level

that many see as a line in the sand.

The Australian and New Zealand dollars were

down about 0.3% each against the greenback, following overnight

jumps.

Precious metals resumed declines on Friday. Spot gold

slipped 0.6% to $4,189 an ounce, following a 3.5% jump

overnight, while spot silver also fell 0.6% to $66.93 an

ounce, after a 5.8% gain.
