SINGAPORE, May 19 (Reuters) - Global shares were on

shaky footing on Tuesday and bonds steadied following a steep

selloff after U.S. President Donald Trump paused a planned

attack on Iran and claimed there was a good chance of a nuclear

deal, sending oil prices lower.

Trump said on Monday he had paused an attack against Iran to

allow time for negotiations to take place on a deal to end the

war, after Tehran sent a new peace proposal to Washington.

He subsequently said there was a "very good chance" the U.S.

could reach an agreement with Iran to prevent Tehran from

obtaining a nuclear weapon.

Investors still remained cautious after being rattled in the

previous session by a weekend drone strike in the United Arab

Emirates.

"We've seen a lot of back and forth already," said Fabien

Yip, a market analyst at IG.

"Until we actually see real action happening (in the Strait

of Hormuz), whereby ships are passing through safely and we see

a material rebound in the numbers of traffic going through in

the Strait, I think the market in general is shrugging off the

commentary from either side."

Brent crude futures fell nearly 2% to $109.94 a

barrel on the back of Trump's comments, while U.S. crude

was down 1.54% to $106.99 per barrel, though both remained more

than 50% above their pre-war levels.

In share markets, MSCI's broadest index of Asia-Pacific

shares outside Japan was down more than 1%.

Japan's Nikkei eased 0.3% and South Korea's Kospi fell

more than 3%. China's CSI300 blue-chip index lost

0.8%.

Nasdaq futures reversed early gains to trade 0.5%

lower, and S&P 500 futures edged down 0.3%. In Europe,

EUROSTOXX 50 futures rose 0.1%, while FTSE futures

and DAX futures were little changed.

The all-important artificial intelligence trade will be

tested by earnings from Nvidia ( NVDA ) that are due on

Wednesday, where expectations are sky-high for the world's most

valuable company.

"Nvidia's ( NVDA ) earnings are the ultimate test for a stock market

that is not only trading at record highs, but one that also had

a breathtaking bounce off of the March lows, as Nvidia ( NVDA ) is the

market's shorthand for everything AI and this market's gains

have been driven in large part by AI over the past few years,"

said Richard Reyle, chief investment officer at Questar Capital

Partners.

BOND SELLOFF ABATES

The fall in oil prices helped stem a steep selloff in global

bonds on Tuesday, although worries remain about any lasting

inflationary shock from the Iran war.

Yields on the benchmark 10-year U.S. Treasury note

eased from a more than one-year high to 4.6034% in

Asian trade, and the two-year yield was down slightly

to 4.0674%.

Japanese government bond yields, which shot to record highs

in the previous session, were similarly down across the curve.

Overnight, G7 finance ministers acknowledged mounting

concerns over public debt and bond market volatility as they met

in Paris.

Markets are now pricing in rate hikes from major central

banks this year on expectations policymakers will have to

tighten policy to combat a resurgence in inflation driven by

higher-for-longer energy prices.

"While the economic rationale for pricing persistently

higher inflation over the coming years on the current supply

shock is weak particularly given the labor market backdrop, a

return of supply-side volatility and the sanguine growth tone in

markets both argue for more risk premium through the inflation

curve," Goldman Sachs analysts said in a note.

In foreign exchange, the dollar has benefited from

safe-haven demand since the onset of the war and was up 0.1% at

158.99 yen, putting traders on alert for any intervention

from Tokyo to shore up its ailing currency.

The euro was down 0.17% at $1.1636. Sterling

similarly fell 0.2% to $1.3408.

Elsewhere, spot gold eased 0.5% to $4,543.26 an

ounce, having come under pressure from rising bond yields.
