Is there any way to know what the money supply is in the United States?

Since things have come to a halt and there are far fewer new car loans, business loans, new real estate projects, student loans, and new credit card debt putting new currency in to the economy. This lack of new money in the economy is what starts of a depression, as there is no new money being made available to pay of the interest on the existing loans. The direct cash payments counteract this, so long as you accept that the national debt will never be repaid or ignore Congress' debt to the Federal Reserve.

Is there some statistic that can be used to compare the lack of new loans and new money versus the $1200 being sent to most people in the USA? For instance, if a person doesn't put $1200 on their credit card when they normally would have, and they get $1200 from the government, in the grand scheme of things it balances out in the fractional reserve bank economy.
