The injection of capital into the market was followed up by calls from Treasury Secretary Hank Paulson to major money market players like Bank of New York Mellon and State Street in Boston informing them that federal money was in the market and they should tell their clients the Feds would be back with a plan to stem the constriction in the credit market.

Paulson knew the $105 billion injection was not a real solution. A broader, more radical answer was needed.

Hours after Paulson made his round of calls to calm the industry, word leaked out that an added $1 trillion bailout of banks was being readied. Investors cheered. At about 3 p.m., news of the plans was filtering up and down Wall Street, fueling a 700-point advance in the Dow Jones industrial average through 4 p.m. Friday.

By that time, Paulson had announced the plan.
