As mentioned in Money Supply October 2008, the money supply has grown by $150 billion or 8% from October 2007 through October 2008.
Upon request, I am listing the contribution of each money supply component to this growth:

Based on this chart, the most significant contribution to this growth has been in domestic private and business checking accounts ($85.3 billion or 57%), which needs to be calculated by adding up retail sweeps and demand deposits, followed by a growth of $29 billion or 19% in cash and an equal amount in government deposits at the Federal Reserve.
The contribution of government deposits at commercial banks, government note balances at repositories, and deposits of foreign banks and institutions has been negligible.
