NEW YORK (Reuters) - The euro had its worst day against the dollar in 16 months on Thursday after the European Central Bank began weaning the euro zone off loose monetary policy, while U.S. Treasury yields rose slightly, hurt by weak demand at an auction of 7-year notes.
The dollar index .DXY rose 0.99 percent, with the euro EUR= down 1.35 percent to $1.1653 after the ECB said it would cut its bond purchases in half to 30 billion euros a month from January. However, it hedged its bets by extending asset purchases by nine months given low inflation.
“Overall, the ECB’s focus on a very cautious and drawn-out tapering process that avoids pushing the euro higher was clearly more dovish than markets had been expecting,” said James Chen, head of research at Gain Capital.
Benchmark 10-year U.S. Treasury notes US10YT=RR last fell 5/32 in price to yield 2.4609 percent, from 2.444 percent late on Wednesday.
The 30-year bond US30YT=RR last fell 10/32 in price to yield 2.9706 percent, from 2.955 percent late on Wednesday.
Yields fell earlier in the session, in line with the euro zone bond market, after the ECB’s meeting.
A report from Politico saying that current Federal Reserve Chair Janet Yellen was out of the running for the top U.S. central bank job briefly nudged rates higher. But a White House official told Reuters: “No final decision has been made.”
Yields weakened later in the day after a soft auction of U.S. 7-year notes drew the weakest demand since August last year.
The U.S. 7-year note was sold at 2.280 percent, higher than the expected yield at the bid deadline. The yield was the highest at an auction for this debt maturity since January.
