NBER is the official source for when recessions start and when they end. They do review the facts as time passes and can adjust when the recessions began or ended.
In the meantime, I read this article on CNBC and it's quite alarming.

Basically it's saying that on top of the $800B so-called stimulus bill and the $700B TARP bill, the Fed has been MONETIZING the debt to the tune of $1.7T and are talking about monetizing another $1T to $2T. Yikes!
What is monetization? It's when the Treasury prints money and the Fed uses that new money to buy back (or not issue new) T-Bills. The effect is hugely inflationary, but also keeps interest rates near zero. By definition, the process converts debt into printed money, or the govt. is just running the printing presses to buy all the stuff the govt. is spending on but really can't afford. In the process, the Fed now has all that debt on its books, and at some point it's going to have to borrow an equivalent amount of money to pay those back.
The national debt went up over $2T in Obama's first 421 days (

Inflation is "too many dollars chasing too few goods." Printing money means "too many dollars" is more likely. So people are buying hedges against inflation - gold and oil.

Gold edges up to a new record
It's not a matter of "if" - it's a matter of WHEN. Inflation.
