Jan 10 (Reuters) - Wall Street was set to open sharply lower on Wednesday as investors were spooked by a report that China is considering slowing or halting purchases of U.S. government debt.
The dollar dropped more than half a percent against a basket of currencies, while long-dated Treasury yields hit fresh 10-month highs after the Bloomberg report said the U.S. bond market was becoming less attractive for Beijing.
"The futures are indicating a nasty opening as climbing yields awaken investors to a possible meltdown in the government bond market," Peter Cardillo, chief market economist at First Standard Financial in New York, wrote in a client note.
If losses hold until markets open, the Dow would open in the red for the first time in 2018.
"For a market that was probably looking for reason to take a pause, it's not unreasonable to use today's rise in yield as a catalyst," said Art Hogan, chief market strategist at B. Riley FBR in Boston.
The CBOE Volatility index, a widely followed measure of market anxiety, jumped 2 points from its life low of 8.56.

"It will be the first time that Corporate America has the ability to talk about guidance that incorporates lower tax rates. It's going to confusing and noisy but will be fascinating, " Hogan said.
