With all the talk of the rate cut you'd think that interest rates were currently at restrictive levels. That's simply not the case. Here are a few charts from the St. Louis Federal Reserve that show interest rates are pretty low by historical standards:
10-Year Treasury
AAA Seasoned Corporate Papar
BBB Seasoned Corporate Paprt
30-Year Conventional Mortgage
Prime Lending Rate
In other words, the current cost of money is far from restrictive. That means the problems in the economy are probably not driven by money being too expensive, but one of confidence. Lenders are still concerned about borrowers ability to pay back a loan even over a short time period. Lower rates won't solve that problem: there is still a ton a bad debt in the system.
