Will Municipal Bonds be the Next Disaster?

It has been an article of faith that municipal bonds are safe investments, but this complacency about the safety of munis may soon be proven unwise.

The last time there was a serious problem in the muni markets was during the Depression, when numerous states and municipalities defaulted.  In my 40-year career, I have found that problems often occur in markets that are not subjected to continuous rigorous scrutiny and are given a pass because of a record of safety.  Prior to 2008, for example, the last sustained national drop in residential real estate was in the 1930’s.  The Black Swan is an unpredictable but monumentally important event, and it always comes from the area you least expect.

In this case, the potential black swan is a huge one. The three biggest categories of debt in the United States are the debt of the federal government and its agencies, mortgage-backed debt and municipal bonds.  Over the past decade, the municipal markets have moved from being the safe haven of widows and orphans to a $2.5 trillion active market, complete with its own indices, ETFs and credit default swaps.   The size and sophistication of the muni market masks the following sources of instability:

  1. The states have for years been underfunding their pension plans, while at the same time adding to their rolls.  There are large gaps between the present value of the future promised benefits and the value of the assets available to pay them.  This is a structural problem that will not go away without a number of years of extraordinary investment returns, a reduction in benefits, increased taxes, or a combination of all three. At the same time, other state-mandated spending (schools, medical support, and public assistance) has increased to more than 50% of the revenues states take in via taxes.  This higher mandated spending has not been matched by the politically unpopular solution of increased taxes. Instead, it has been addressed in large part by issuing bonds
  2. In the current economic downturn, the main sources of state revenues – property, income and sales taxes – have all taken a hit. If a home has declined in value, then, with some delay, the property tax assessment will also fall.  Houses that stand vacant often do not pay taxes, and homeowners in default on their mortgages are unlikely to pay property taxes.  Tax receipts will not recover until house prices get back above their pre-crisis levels.  Does anyone want to predict when that will happen?
