Structural Deficit

How It Works

Unlike a cyclical deficit caused by a temporary recession, a structural deficit exists across the business cycle regardless of economic conditions. Common causes include rising pension obligations (Illinois carries roughly $140 billion in unfunded state and local pension liabilities, and several Illinois cities including Chicago face structural shortfalls driven primarily by pension contributions), healthcare and OPEB costs growing faster than revenue (typically 5-8% annually versus 2-3% revenue growth), deferred maintenance backlogs creating accelerating repair bills, and collective bargaining agreements with salary escalators that outpace tax base growth. Structural deficits are measured by comparing recurring revenues to recurring expenditures over a full economic cycle, excluding one-time items such as asset sales, bond proceeds, ARPA federal relief, and extraordinary fund balance draws. Cities relying on one-time revenue to cover recurring costs are flagged by Moody's, S&P, and Fitch rating reports as carrying a "structurally unbalanced" operating profile, typically leading to rating downgrades of one to three notches within 18-36 months. Resolving structural deficits requires either permanent revenue increases (tax rate hikes, new revenue sources, annexation), permanent spending cuts (workforce reductions, service cuts, pension reform), or both. Detroit's July 2013 bankruptcy was preceded by more than a decade of structural deficits papered over with borrowing and asset sales. The structural deficit signal is a top input to the 25% budget balance and 10% trend direction factors of the CitySpend Fiscal Health Score.
