SINGAPORE, April 22 (Reuters) - U.S. stock futures rose

and the dollar wavered on Wednesday after President Donald Trump

said he would indefinitely extend the Iran ceasefire keeping

sentiment buoyed although with the Strait of Hormuz still closed

oil held onto its recent gains.

Trump's announcement appeared to be unilateral, and it was

not immediately clear whether Iran, or U.S. ally Israel, would

agree to extend the ceasefire, which began two weeks ago.

Markets though took the news in stride with risk momentum

intact. S&P futures rose 0.5% while Nasdaq futures

gained 0.6% in early Asian hours.

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

eased 0.14% after hitting a seven-week high in

the previous session. Japan's Nikkei was down 0.2% as

traders consolidated their recent gains.

After a sharp selloff in March due to war in the Middle

East, markets across the globe have swiftly rebounded this month

and are back at pre-war levels as the prospect of a peace deal

and the ceasefire have helped risk sentiment.

"It appears markets were right to assume peak war

uncertainty is behind us," said Matt Simpson, a senior market

analyst at StoneX.

"Risk seems likely to remain buoyant and dips viewed

favourably by equity bulls. The closure of the Strait of Hormuz

is already priced in."

Trump said he would continue the U.S. Navy's blockade of

Iran's ports and shore. Tehran has effectively closed the Strait

of Hormuz through which one-fifth of world's energy supply

usually flows, causing a global energy shock.

U.S. West Texas Intermediate crude futures climbed

0.44% to $90.12 a barrel. The benchmark contract rose 2.8% on

Tuesday.

In currencies, the euro last fetched $1.1748 in early

trading. The yen was a bit stronger at 159.26 per

dollar and sterling firmed to $1.35195.
