March 25 (Reuters) - U.S. stock index futures climbed on

Wednesday, after media reports that the U.S. was seeking a

month-long ceasefire in its war with Iran, allaying some

investor fears around prolonged energy supply disruptions.

The New York Times reported that Washington sent Iran a

15-point plan to end the war. Israel's Channel 12 said the U.S.

planned to discuss the plan during the proposed ceasefire.

Tehran has denied any negotiations and Iran and Israel

exchanged airstrikes on Wednesday.

"While we don't envision U.S. escalation going forward, we

would also be surprised to see a near-term resolution... There

could be a scenario where the combination of a resilient Iran

and rising energy prices forces President Trump to escalate, but

that does not appear imminent," said Mike O'Rourke, chief market

strategist at JonesTrading.

Global markets drew comfort from the reports, hoping for a

breakthrough that could help restore shipping through the

crucial Strait of Hormuz. Oil prices ticked about 4% lower,

supporting broader risk appetite.

"Investors should be cautious about assuming a swift

resumption of energy flows, but our base case is that they will

be restored without meaningful or lasting economic damage," said

analysts at UBS Global Wealth Management.

Wall Street's main indexes closed lower on Tuesday after

trading in limbo, as a relief rally sparked by President Donald

Trump's decision to postpone strikes on Iran's power network

fizzled out.

At 05:13 a.m. ET, Dow E-minis were up 437 points, or

0.94%, S&P 500 E-minis were up 60 points, or 0.91%, and

Nasdaq 100 E-minis were up 261.75 points, or 1.08%.

The spike in oil prices tied to the Iran conflict has

revived inflation concerns, complicating the interest rate

outlook of central banks.

Markets are not pricing in any easing from the Federal

Reserve this year, compared with two cuts anticipated before the

war broke out, according to CME Group's FedWatch Tool.

Meanwhile, U.S.-listed shares of Arm jumped 12.6% in

premarket trading after the company unveiled a new AI data

center chip that is expected to bring billions of dollars in

revenue.

Other chipmakers also inched higher with Intel ( INTC ) up

3.8%, Marvell Technology ( MRVL ) gaining 2.9% and Nvidia ( NVDA )

1.3% higher.

U.S.-listed shares of JD.com and Alibaba

gained more than 4% each after Chinese state media and the

regulator urged the food delivery platform industry to end a

bleeding price war.

Destiny Tech100 ( DXYZ ) surged 20% after a report that

SpaceX aims to file its IPO prospectus as soon as this week.

SpaceX is the fund's largest equity holding.

Robinhood Markets ( HOOD ) added 3.6% after the trading

platform announced a new $1.5 billion share buyback program.
