The Federal Home Loan Bank System sold $3 billion of its three-year global bonds at higher yields over U.S. government notes.

The bonds, which mature Sept. 16, 2011, were priced to yield 3.683%, or 133 basis points more than similar-maturity U.S. Treasuries, according to a statement Tuesday from the system's finance office.

In July the system sold $4 billion of three-year notes at a spread of 104 basis points.

Barclays PLC, JPMorgan Chase & Co., and Merrill Lynch & Co. Inc. managed the latest sale, the statement said.

U.S. investors bought at least 34% of the notes sold Tuesday, up from at least 26% of the notes sold in July, the finance office said. Asian buyers bought at least 14%, down from 24% in July, and European investors acquired at least 6%, down from 10% last month. Central banks bought at least 20% of the debt, down from 22%.
