Budget Watchdogs Warn Mamdani Not to Bet on Wall Street or Tap Rainy Day Funds

New York’s fiscal balancing act highlights the risks of relying on Wall Street’s whim and rainy-day funds to keep Gotham running—just as clouds gather on the economic horizon.

A $127bn wager hangs in the balance in New York City. Mayor Zohran Mamdani’s freshly unveiled budget, while earning points for sharpening the pencils of municipal accounting, has come under fire from watchdogs worried that the city is betting on luck more than prudence. Wall Street’s tottering fortunes, a contested raid on rainy-day reserves, and a mooted property-tax hike undergird a plan that, critics say, may prove a rickety scaffold when the wind next changes.

The mammoth proposal imagines revenue rising on the coat-tails of continued financial-sector exuberance. Perhaps, suggests Mamdani, another year of buoyant bonus pools and capital-gains shuffling will tide Manhattan’s tax rolls over. But both Comptroller Mark Levine and the ever-cautious Independent Budget Office this week performed the municipal equivalent of clearing their throats. Wall Street’s largesse, they warn, has rarely proved a bedrock on which to build.

Levine, in polite understatement, told the Council’s scrutiny session: “The Wall Street boom may continue, and I hope it does. But we should not count on it.” Rare is the city budget chief who would gamble the city’s future on equity markets reaching for ever-loftier summits. The city’s forecast for tax revenues already shrinks under the glare of Moody’s, the credit-rating agency, which has shifted its outlook for the city from “stable” to “negative” for the first time since the covid pandemic.

Moody’s cites projected spending outpacing likely receipts through 2028—a signal, not a fire alarm, but a sign that the city’s borrowing costs could yet rise if fiscal drift persists. While New York’s rating has not slid down the credit ladder, the outlook bodes ill for closing what are certain to be painful future budget gaps.

In the near term, Mamdani’s plan offers up Albany as deus ex machina. Both chambers of the state legislature, in their budget drafts, include tax rises for wealthy New Yorkers—an income and corporate levy that echoes City Hall’s own ask. Yet Governor Kathy Hochul, the state’s fiscal referee, seems as likely to acquiesce as Wall Street is to embrace monastic austerity. The city must therefore prepare for disappointment, a sentiment seasoned observers will find familiar from past budget seasons when tax hikes sizzled in committee before quietly evaporating in the final deal.

Should relief from above not materialise, the mayor proposes other politically hazardous remedies. Drawing from the city’s $8bn rainy-day fund appeals to none of the fiscal guardians, who argue that such reserves are for genuine crises, not the everyday headaches of municipal accounting. The very presence of this emergency cash was a hard-won reform, enacted in 2019 after decades when New York largely muddled through disasters with crossed fingers. Reckless or even merely cavalier withdrawals would erode a margin for true catastrophe.

The alternative centrestage is a broad-based property tax hike. Here, Levine and others see more peril than promise. Property taxes already weigh heavily on many outer-borough homeowners; raising them risks feeding the city’s chronic inequalities, a problem neither left nor right claims credit for exacerbating. The spectre of rising housing costs has already driven some residents to decamp for less taxing pastures.

Meanwhile, all of this unfolds against the backdrop of New York’s still-fragile post-pandemic economy. The city may have regained most private-sector jobs, but commercial property revenues remain tepid, especially as office towers stubbornly resist full occupancy. Wall Street’s stellar returns of the past two years owe much to unusual liquidity that neither history nor the Federal Reserve promises to prolong.

Fiscal fantasyland meets reality check

Elsewhere, America’s cities face similar headaches. San Francisco’s budget gorilla remains the stunted return to the downtown office grid; Chicago, for all its fiscal flamboyance, still scrambles to plug pension holes. Internationally, London’s city government is even more revenue-constrained, utterly dependent on central government transfer. Yet New York, unlike its rivals, sits nearer both a financial geyser and a political tangle between city and state that can, in the best years, yield windfalls—and in others, heartbreak.

Reliance on Wall Street is, of course, double-edged. During the pandemic, surging markets capped New York’s deficits, helping it steer clear of drastic service cuts. But the city has long been the canary in the American coal mine for fiscal nerves: back in the 1970s, it teetered on the edge of default, rescued only by a state-and-federal bailout. Institutional memory runs deep; every syrupy projection is haunted by that crisis.

Prudence suggests City Hall must do more than invoke hope. The usage of rainy-day funds in non-crisis periods dulls the tool’s edge. Raising property taxes brings diminishing returns the moment migration, price sensitivity, or political backlash turn those gains into lost base. Meanwhile, an over-reliance on Albany offers little more than a deferred reckoning, since the city’s growing needs must ultimately be squared with its own resources or efficiency reforms.

So where should New York look? The answer is neither to double-down on financial froth nor to cannibalise its own household savings. In the end, the city’s long-run fiscal health demands a cautious blend of modest revenue growth—ideally achieved through economic dynamism rather than tax rate hikes—paired with an honest reckoning with spending priorities. As with any good tonic, moderation is key.

The latest budget skirmish thus portends neither doom nor utopia, but it signals the need for steelier discipline. The test for Mayor Mamdani and his colleagues is whether they can avoid the twin temptations of head-in-the-sand optimism or indiscriminate belt-tightening, and instead chart a path that keeps the city solvent—without mortgaging its future to fortune’s wheel, Albany’s moods, or the memory of bygone booms. ■
