July 22 (Reuters) - U.S. stock index futures fell on Wednesday as investors shunned risky assets after Washington ordered a shutdown of the Chinese consulate in Houston, escalating tensions between the world’s two largest economies.
In response, China is considering the closure of U.S. consulate in Wuhan, a person with direct knowledge of the matter said.
The news comes after three straight sessions of gains for the S&P 500, driven by optimism about an eventual coronavirus vaccine, further fiscal support for the pandemic-hit economy and a batch of positive second-quarter reports.
The benchmark index is less than 4% below its record closing high hit in February.
