0455 GMT - It has been a good week for U.S. bond auctions, ING's Padhraic Garvey and Benjamin Schroeder say in a note. Solid 10- and 30-year Treasury auctions over consecutive days show there is a level where buyers step in, say Garvey, regional research head for Americas, and rates strategist Schroeder. "The 30-year auction saw a strong international and domestic bid that took down the paper at secondary market levels, and the previous day's 10-year auction came a tad rich to secondary," they say.
