Here's how U.S. states are preparing for a potential recession

Last month, the World Bank said a global recession is likely. And within the U.S., there is a 57% probability of a recession by January 2024, according to an analysis from the New York Fed.

How each state may fare on an individual basis in the event of a recession varies widely. Part of that is because a recession means more of a reliance on rainy day funds — or state reserve funds.

Justin Theal, an officer with the Fiscal 50 project at Pew Charitable Trusts, described rainy day funds as a state's "best line of defense during a recession without major cuts."

"If we assume that we are going to head into a recession next year, states are more prepared than they have ever been for a recession, and one of the key things to look at for state preparedness is how much they have in their rainy day funds," Theal told Yahoo Finance.

"Fortunately, most states have a record level of rainy day funds right now and still significant amount of flexible federal pandemic aid that is going to provide some breathing room to help manage these budget uncertainties in the short term," he added. "But as inflation is more persistent than expected, it can really exacerbate many of the long-term challenges that many of the states' parties face."

Theal stressed the importance of states closely analyzing their savings to predict what their budgets could look like in future uncertain economic conditions and to make policy changes accordingly.

Financial tools like budget stress tests can help determine if a state's revenue stream is volatile. California, New Mexico, North Carolina, Utah, and Maine are frequent users of the budget stress test, which helped North Carolina reach its recommended savings goal in 2022.

A majority of states have a sufficient amount in their rainy day funds, according to Pew Charitable Trusts. California has the highest savings with over $47 billion, and Montana has the least with $118 million.

However, large funds aren't always the best indicators for how long a state can rely only on its savings, as some states with larger budgets tend to have more expenditures. For example, Wyoming is the only state with a reserve fund of over $1 billion and can use its rainy day funds for up to a year, which would equal nearly all of its spending. Illinois and Washington, on the other hand, would last only four days for just 1% of their typical spending.

And as the Urban Institute noted, "because no two states share identical political or economic characteristics, it is hardly surprising that states experience differential responses to upturns or downturns in the economy."
