Just before Thanksgiving, the Federal Deposit Insurance Corporation released its Quarterly Banking Profile for the third quarter of 2015. While the data shows continued slow improvement to the overall conditions of the banking system, regional banks continue to suffer from hangover effects of the Great Credit Crunch.

In this environment, investors should be reducing holdings in these seven regional banks -- BB&T Corp (BBT) - Get Report , Fifth Third Bancorp (FITB) - Get Report , PNC Financial (PNC) - Get Report , Regionals Financial (RF) - Get Report , SunTrust (STI) - Get Report , U.S. Bancorp (USB) - Get Report and Zions Bancorp(ZION) - Get Report , which have fourth quarter gains of between 8% and 15%.

FDIC Chairman Martin J. Gruenberg discussed concerns about growing interest rate and credit risks as banks extend further out on the yield curve to mitigate the impact that low rates have on net interest margins. The FDIC is monitoring an increasing mismatch between asset and liability maturities. In addition, banks have been increasing their lending in higher risk loan categories such as construction and development.

Also of concern are loan portfolios in regions of the country that depend upon oil and gas revenues. Loan exposures are up while the price of energy is down, which puts lenders in a squeeze.

As a result of these concerns, net income margins are suffering as higher yielding assets that reach maturity are replaced by lower-yielding investments. NIM is down about 80 basis points since 2009 and is only slightly higher this quarter than the 30-year low set in the first quarter. This appears symptomatic of a banking system unwilling to make prudent loans to consumers and small businesses.

Wall Street has been telling investors that regional banks will benefit from higher interest rates, but the FDIC does not share this opinion. As the mismatch between asset and funding maturities extends, banks become more vulnerable to rising interest rates and to widening spreads versus the U.S. Treasury yield curve.

The FDIC is also worried about increasing exposures to riskier debt categories such as loans to leveraged commercial borrowers, and relaxed underwriting standards for auto loans and multifamily housing construction.
