World equity markets edged lower on Monday as investors digested the likelihood of U.S. interest rates being lowered soon, even as oil prices jumped amid increased tensions in the Middle East.

The benchmark S&P 500 index and the Nasdaq finished lower after giving up early gains, while the Dow climbed. European shares ended slightly down, with trading subdued in the London market, which is closed for a public holiday. Japan's blue-chip Nikkei stock index also closed down almost 0.7 per cent as the yen firmed.

The Dow Jones Industrial Average rose 0.16 per cent to 41,240.52, the S&P 500 lost 0.32 per cent to 5,616.84 and the Nasdaq Composite lost 0.85 per cent to 17,725.77. MSCI's World Index of stocks across the globe fell 0.20 per cent to 829.64.

The stock market "is digesting a lot of news: obviously there was a rally on Friday on (Federal Reserve Chair Jerome) Powell's comments and we thought durable goods orders come in good," said Ben McMillan, principal and chief investment officer at IDX Insights in Tampa, Florida.

"Historically rate cuts have actually preceded equity market weakness because rates are being cut for a reason."

AI chip maker Nvidia reports earnings on Wednesday, and market expectations are sky-high. Nvidia stock is up some 160 per cent year-to-date, accounting for around a quarter of the S&P 500's 18 per cent year-to-date gain.

"The big thing this week is really Nvidia more than any of the macro stuff. I think folks are really focused on Nvidia because that's been kind of the bellwether for the risk-on trade this year," McMillan added.

Israel and Hezbollah traded rocket salvos and airstrikes on Sunday, stirring worries about possible oil supply disruptions if the conflict escalated. Also supporting crude prices was Libya's eastern-based government announcement of the closure of all oil fields, which halted production and exports.

Brent crude futures closed up 3.05 per cent at US$81.43 a barrel, while U.S. crude futures settled 3.5 per cent higher at US$77.42 a barrel.

New orders for long-lasting U.S.-made goods, items ranging from toasters to aircraft, surged by 9.9 per cent last month, a solid rebound from a decline in June that beat analyst expectations, Commerce Department data showed.

In a highly-anticipated speech to the Jackson Hole symposium on Friday, Powell said the time had come to start easing policy and emphasised the central bank did not want to see further weakening in the labour market.

European Central Bank chief economist Philip Lane struck a more cautious note in his Jackson Hole speech, saying the central bank was making "good progress" in cutting euro zone inflation back to its 2 per cent target, but success was not yet assured.

The yield on benchmark U.S. 10-year notes rose 1.3 basis points to 3.82 per cent. The two-year note yield, which typically moves in step with interest rate expectations, rose 2.7 basis points to 3.94 per cent.

Fed fund futures are fully priced for a quarter-point cut at the Sept. 18 meeting, and imply a 39.5 per cent chance of a 50 bps move. The market also has 103 bps of easing priced in for this year and another 122 bps in 2025.

The ECB has already started cutting rates, with a 25 bps reduction in July, with a further two quarter point reductions priced in by year-end.

"I think it's more likely than not that we're going to see 75 bps cut this year. And the market has some potential readjustment for less rate cuts than is being priced in," McMillan said.

Dollar index up, gold firms

U.S personal consumption and core inflation data are due on Friday, along with a flash reading on European Union inflation. Most analysts expect the data will allow for rate cuts in September.

The Japanese yen rose to a three-week high against the U.S. dollar, with the dollar dropping to 143.45 yen but pared losses and was last slightly up 0.14 per cent at 144.56.

The dollar index, which measures the greenback against a basket of currencies including the yen and the euro, gained 0.24 per cent at 100.84, with the euro down 0.28 per cent at US$1.1159. Gold prices firmed, nearing the recent record high on safe-haven demand. Spot gold added 0.31 per cent to US$2,518.27 an ounce. U.S. gold futures gained 0.28 per cent to US$2,515.50 an ounce.
