Crain's Tom Henderson reports that Comerica is shaky, its stock holders up in arms and many calling for the head of CEO Ralph W. Babb Jr. While he got re-elected at the recent annual meeting he is on very thin ice to produce or even sell the bank. One of the rumored likely buyers includes the mighty Bank of Montreal.

As for Babb, I confess to a degree of Schadenfruede. After all it was he who kind of kicked us when we were down in 2007 by moving the 150 year + Detroit bank's HQ to Dallas. He was heading for the greener pastures of oil investment loans and now finds himself holding $689 million in non-performing frack-bust oil industry loans with 56% now at risk of default. Ironically healthy Michigan deposits and loans are largely responsible for floating him now while Texas withers.
