Rising yields on certain U.S. municipal infrastructure bonds reveal growing concerns among investors that some local governments are facing a greater risk of default, which might give municipal bond exchange traded fund (ETF) investors some pause.

A relative increase in some bonds reflects skepticism among some analysts that some regions will be able to pay back their debts, reports EMII.com. What’s more worrisome for investors with capital in related funds is that the rising yields on Build America Bonds come even though most analysts believe the federal government would be very likely to intervene should a state or municipality be forced into bankruptcy.

William Selway for BusinessWeek reports that the current U.S. financial overhaul will alter the municipal bond business by curbing Wall Street’s sway over its regulator, increasing oversight of advisors and protecting governments that enter derivative deals.

State and local governments were hit with billions of dollars in unexpected expenses when interest-rate swaps designed to protect against rising borrowing costs backfired amid the financial crisis. This is what has ignited the intervention by Congress. [Fixed-Income ETFs Still a Good Idea?]

Provisions include:

  • The 2,300-page bill lawmakers agreed on last week would strip banks and securities firms of their majority control of the Municipal Securities Rulemaking Board.
  • Require local-government financial advisers to register with regulators and impose rules on banks that sell derivatives such as interest-rate swaps to local governments.

On the risk scale, municipal bonds fall just under Treasury bonds and defaults can happen, but they are very rare. It’s wise to be mindful of this risk, though.
