NEW YORK, Sept 12 (Reuters) - U.S. Treasury yields fell across the board on Thursday, in line with the European bond market, after the European Central Bank cut interest rates to a record low and said it would restart asset purchases to boost its slumping economy.
The ECB cut its deposit rate to an all-time low of -0.5% from -0.4% and will restart bond purchases of 20 billion euros a month from November, it said in a statement.
In early morning trading, U.S. benchmark 10-year note yields fell to 1.681% from 1.733% late on Wednesday.
Yields on 30-year bonds were also lower at 2.149% from 2.208% on Wednesday. (Reporting by Gertrude Chavez-Dreyfuss Editing by Raissa Kasolowsky)
