Bernankeâs assessment of the economy thatâs boosting demand for bonds even with yields near the lowest on record. Commercial lenders purchased $78.2 billion of Treasuries and securities of agencies in January and February, compared with $62.6 billion in all of 2011, bringing their holdings to $1.78 trillion, Fed data show. Deposits exceeded loans by a record $1.63 trillion last month, up from $1.17 trillion in January 2011, providing scope to buy more bonds.
