Municipal yields are back up. The Center on Budget and Policy Priorities says states in the USA will have to close budget gaps of $140 billion in fiscal year 2012, ending in June, down from $160 billion this year. But real shortfalls will increase because federal stimulus funds that helped state and local governments will fall from $59 billion this year to $6 billion next year. Local governments depend on states for one third of their revenue, according to a Congressional Budget Office report, which makes them vulnerable. Property taxes account for a quarter of local government revenue and this too will be declining with declining assessed values. The Federal Reserve Act limits open-market purchases of munis to ones with maturities of less than 6 months, which reduces the scope for help from the Fed.
