Two weeks after Detroit declared bankruptcy, cities, counties and other local governments in Michigan are getting a cold shoulder in the municipal bond market, the New York Times DealBook blog reported yesterday. Borrowing costs are up around the state, in some cases drastically. Saginaw County yesterday became the latest casualty when it said it was delaying a $60 million bond sale planned for Friday. It had hoped to put the proceeds into its pension fund. It was the third postponed bond sale in Michigan since Detroit dropped its bombshell on July 18. Earlier this week, the city of Battle Creek said that it would postpone a $16 million deal scheduled for August because of concerns that investors would demand interest rates that were too high. And the previous week, Genesee County withdrew a $54 million bond sale from the market for the same reason.
