Global markets were mixed after U.S. President Donald Trump said he has firmed up his choice for the next Federal Reserve chairman, with reports pointing to Kevin Warsh as the likely pick.

Wall Street futures were in the red after a mixed close yesterday, as investors were rattled by the latest earnings reports and worried about whether hefty spending on artificial intelligence would pay off for mega-cap tech companies.

TSX futures followed sentiment lower as commodity prices slid.

In Canada, investors are getting results from Canadian National Railway Co., Imperial Oil Ltd., Brookfield Renewable Partners LP and Brookfield Business Partners LP.

On Wall Street, markets are watching earnings from Exxon Mobil Corp., Chevron Corp., American Express Co. and Verizon Communications Inc.

Warsh “is on record as saying he prefers lower rates”, said Damien Boey, a portfolio strategist at Wilson Asset Management in Sydney. “But the ‌tradeoff that he makes with lower ‍rates is that he wants the Fed to have a smaller balance sheet.

“The markets are reacting as if thinking: ‘What would the world ‍look like with a smaller Fed balance sheet?’ ”

In Asia, Japan’s Nikkei closed 0.1 per cent lower, while Hong Kong’s Hang Seng fell 2.08 per cent.

Oil prices dropped on signs the U.S. may engage ‍in dialogue with Iran over its nuclear program, reducing concern over potential supply disruptions from a U.S. attack.

West Texas Intermediate (WTI) crude dropped 1.1 per cent to US$64.70 a barrel.

“President ⁠Trump’s willingness to give diplomacy a chance regarding Iran seemingly makes a U.S. military intervention less likely than yesterday,” said PVM Oil Associate analyst Tamas Varga.
