HONG KONG - Equities fell on Wednesday on lingering worries about the outlook for US interest rates, while oil prices extended their gains after an attack on a ship in the Red Sea stoked fresh worries about supplies from the Middle East.
With crucial inflation data out of the United States due at the end of the week, investors are largely playing a waiting game, with many inclined to sell after a recent run-up.
However, a forecast-beating read on consumer confidence in the world's top economy dented hopes that the Federal Reserve will have room to cut borrowing costs this year, while the mood was also soured by a weak Treasury sale that saw yields push higher.
Meanwhile, US central bank official Neel Kashkari warned that decision-makers had not ruled out a possible hike if they continue to struggle to bring prices down to their two percent target.
Wall Street's three main indexes ended mixed on their first day after a long weekend, with sentiment clouded by the government bond sale and the Conference Board gauge of May consumer confidence.
"The reading is still weak, being much closer to the bottom than the top of its past 10 years range. Nevertheless, this data point is the second successive upside surprises in the releases," said Ray Attrill of National Australia Bank.
Investors are now pricing in one cut before the year's end -- compared with as many as six tipped in January.
Asian investors shifted nervously Wednesday and markets fell across the region, with Hong Kong leading the losses owing to heavy selling in Chinese tech firms.
Tokyo, Sydney, Seoul, Singapore, Mumbai, Taipei, Manila, Bangkok, Wellington and Jakarta were all in the red.
London, Paris and Frankfurt also retreated.
Shanghai edged up as the International Monetary Fund lifted its forecast for Chinese economic growth to five percent in light of recent policy announcements. That is up from its previous estimate of 4.6 percent.
Oil prices rose again on geopolitical concerns after a bulk carrier was attacked in the Red Sea, a key waterway for shipping and particularly crude.
The strike comes amid heightened concerns about tensions in the region and as Israeli forces continue a ground invasion of Rafah in southern Gaza.
Also on traders' minds is the upcoming meeting of OPEC and other key oil producers that is expected to see them rollover output cuts.
Still, Warren Patterson, of ING Groep, said: "Geopolitical tensions continue to overshadow the market, but until we see supply losses, I think upside is limited.
"We need to see confirmation of a full rollover of cuts for the market to move significantly higher."
