Asian stocks edged lower and US equity-index futures slid as trade conflicts showed no signs of abating, with Nvidia Corp. saying the US put new restrictions on some chip exports to China.

Contracts for the Nasdaq 100 fell more than 1.4% in early trading and S&P 500 futures dropped 0.9% after Nvidia slumped in after-hours trading. Gold, a safe haven asset that tends to gain when risk assets drop, hit a new record on Wednesday. Bonds held on to the previous session’s gains driven by a Treasury official’s comment on potential rule change that could lower trading costs for banks. The dollar slipped.
