TSLF meaning in General ?

The Term Securities Lending Facility (TSLF) was a 28-day facility managed by the United States Federal Reserve offering Treasury general collateral (GC) (i.e., Treasury bills, notes, bonds and inflation-indexed securities) to the primary dealers in exchange for other program-eligible collateral. It was created to combat the liquidity crisis in American banks that had begun in late 2007, part of the broader financial crisis of 2007-2008. The facility was open from March 2008 through January 2010.

This is different from the System Open Market Account (SOMA) Securities Lending program which offers specific Treasury securities held by SOMA for loan against Treasury GC on an overnight basis. Dealers bid competitively in a multiple-price auction held every day at noon. The TSLF offers Treasury GC held by SOMA for a 28-day term. Dealers bid competitively in single-price auctions held weekly and borrowers will pledge program-eligible collateral.
