Procter & Gamble Co. obtained a 2.3 percent interest rate on its $1 billion of 10-year notes issued yesterday, a record low for the maturity, as corporate bond sales climbed to the most in almost three months.

P&G, the world's largest consumer-products company, also sold $1 billion of two-year, floating-rate notes, according to data compiled by Bloomberg. Offerings in the U.S. reached $17.6 billion, the most since $21.2 billion was sold Nov. 7, as International Business Machines Corp. issued $2.5 billion of debt and Petroleos Brasileiro SA raised $7 billion.

Issuers are seeking to lock in falling yields on investment-grade corporate bonds as Europe's debt crisis fuels demand for the relative safety of dollar-denominated securities and confidence builds that the region's struggles won't disrupt a recovery in the world's largest economy. January sales fell 19 percent from a year earlier to $102.6 billion, leaving investors eager to spend cash on offerings, said Adrian Miller, fixed- income strategist at GMP Securities LLC.
