LIKE millions of homeowners, shrewd state and local governments are looking to refinance. Interest rates have hit rock bottom. So why not save some public money by replacing old debts with new ones at lower rates?

The bad news for taxpayers is that such easy refis are out of the question for many governments and agencies short on cash. And that’s because these borrowers have been trapped by Wall Street.

Behind all of this is — you guessed it — derivatives. Bankers have embedded interest-rate swaps in many long-term municipal bonds. Back when, they persuaded states and others to issue bonds and simultaneously enter into swaps. In these arrangements, the banks agreed to make variable-rate payments to the issuers — and the issuers, in turn, agreed to make fixed-rate payments to bond holders.
