State Debt Woes Grow Too Big to Camouflage

In Greece, a newly elected prime minister may have struck the match last fall, when he announced that his predecessor had left a budget deficit three times as big as disclosed.

Greece’s creditors might have taken the news in stride, but in their weakened condition, they did not want to shoulder any more risk from Greece. They refused to refinance its maturing $54 billion euros ($72 billion) of debt this year unless it adopted painful austerity measures.

Could that happen here?

In January, incoming Gov. Chris Christie of New Jersey announced that his predecessor, Jon S. Corzine, had concealed a much bigger deficit than anyone knew. Mr. Corzine denied it.

So far, the bond markets have been unfazed.

Moody’s currently rates New Jersey’s debt “very strong,” though a notch below the median for states. Moody’s has also given the state a negative outlook, meaning its rating is likely to decline over the medium term. Merrill Lynch said on Monday that New Jersey’s debt should be downgraded to reflect the cost of paying its retiree pensions and health care.

In fact, New Jersey and other states have used a whole bagful of tricks and gimmicks to make their budgets look balanced and to push debts into the future.

One ploy reminiscent of Greece has been the use of derivatives. While Greece used a type of foreign-exchange trade to hide debt, the derivatives popular with states and cities have been interest-rate swaps, contracts to hedge against changing rates.

The states issued variable-rate bonds and used the swaps in an attempt to lock in the low rates associated with variable-rate debt. The swaps would indeed have saved money had interest rates gone up. But to get this protection, the states had to agree to pay extra if interest rates went down. And in the years since these swaps came into vogue, interest rates have mostly fallen.

Swaps were often pitched to governments with some form of upfront cash payment — perhaps an amount just big enough to close a budget deficit. That gave the illusion that the house was in order, but in fact, such deals just added hidden debt, which has to be paid back over the life of the swaps, often 30 years.

Some economists think the last straw for states and cities will be debt hidden in their pension obligations.

Pensions are debts, too, after all, paid over time just like bonds. But states do not disclose how much they owe retirees when they disclose their bonded debt, and state officials steadfastly oppose valuing their pensions at market rates.

Joshua Rauh, an economist at Northwestern University, and Robert Novy-Marx of the University of Chicago, recently recalculated the value of the 50 states’ pension obligations the way the bond markets value debt. They put the number at $5.17 trillion.

After the $1.94 trillion set aside in state pension funds was subtracted, there was a gap of $3.23 trillion — more than three times the amount the states owe their bondholders.

“When you see that, you recognize that states are in trouble even more than we recognize,” Mr. Rauh said.

With bond payments and pension contributions consuming big chunks of state budgets, Mr. Rauh said, some states were already falling behind on unsecured debts, like bills from vendors. “Those are debts, too,” he said.

In Illinois, the state comptroller recently said the state was nearly $9 billion behind on its bills to vendors, which he called an “ongoing fiscal disaster.” On Monday, Fitch Ratings downgraded several categories of Illinois’s debt, citing the state’s accounts payable backlog. California had to pay its vendors with i.o.u.’s last year.

“These are the things that can precipitate a crisis,” Mr. Rauh said.
