NEW YORK, Oct 10 (Reuters) - Prices for U.S. 30-year Treasury bonds trimmed losses to turn briefly flat on Wednesday, shortly before an auction of 10-year debt.
Bond prices had fallen earlier in the day as traders reduced holdings to make room for $21 billon in 10-year note supply.
But 10- and 30-year debt prices pared losses shortly ahead of the auction, with the 30-year bond briefly erasing the day's losses before dipping again.
