Also correct. This is the opposite end of the spectrum.
The Keynesian cycle would tell us that when inflation started rising because of the oil crisis, raise interest rates, cut back on the money supply, and let things re-balance themselves. However, the credit crunch needed lower interest rates to keep the pump flowing, or else everyone would have simply hoarded money and we get recession. The credit crunch won over the oil crunch, and we got inflation. If they had chose to raise interest rates to deal with the oil, inflation wouldnt be as bad but credit and housing would be a worse mess, and that could even be a bigger economic threat. This was a perfect storm for economic fuckitude, and one more side effect of our economy relying on a foreign product priced in our currency.
