Theoretically if more money is available with banks then banks can lend more at lesser interest rates.If credit is available freely and at cheaper rates corporate will borrow more and invest in business thus creating more jobs and in turn increasing the over all demand. So, if demand is more companies can sell more goods and make more profits thus increasing their shareholders value.This cycle will effect markets in a positive way. All this mechanism to take effect will take several months but on anticipation of the result markets will react immediately.
