The Flawed Logic of Large-Scale U.S. Stimulus and Its Implications for Global Markets

The U.S. fiscal trajectory has entered a perilous phase, driven by a combination of large-scale stimulus measures, structural spending imbalances, and a lack of meaningful revenue reforms. According to the Congressional Budget Office (CBO), the federal deficit is projected to balloon from $1.4 trillion in 2023 to $2.7 trillion by 2033, with debt held by the public reaching 118% of GDP by 2033—the highest level in U.S. history More Than Tariffs: Behind the US Dollar’s Decline, [https://www.morningstar.com/markets/more-than-tariffs-behind-us-dollars-decline]^[2]. This trajectory, compounded by the recent One Big Beautiful Bill Act of 2025, which extends tax cuts and introduces new deductions for seniors, has exacerbated concerns about long-term fiscal sustainability 2025 Spring Investment Directions | BlackRock, [https://www.blackrock.com/us/financial-professionals/insights/investment-directions-spring-2025]^[5]. The flawed logic of these policies lies in their assumption that perpetual deficit spending can be decoupled from currency devaluation and investor confidence erosion—a premise increasingly challenged by global markets.

The Fiscal Imbalance and Dollar Devaluation Risks

The U.S. dollar's value has already begun to reflect these fiscal pressures. In 2025 alone, the dollar lost 11% of its value, marking its largest decline in over 50 years and ending a 15-year bull cycle Devaluation of the U.S. Dollar 2025 | Morgan Stanley, [https://www.morganstanley.com/insights/articles/us-dollar-declines]^[1]. Morgan Stanley analysts predict an additional 10% drop by the end of 2026, driven by rising deficits, trade policy uncertainty under the Trump administration's tariff regime, and a deteriorating credit profile Devaluation of the U.S. Dollar 2025 | Morgan Stanley, [https://www.morganstanley.com/insights/articles/us-dollar-declines]^[1]. The recent Moody's downgrade of the U.S. credit rating further underscores these risks, signaling a loss of confidence in the government's ability to manage its debt burden More Than Tariffs: Behind the US Dollar’s Decline, [https://www.morningstar.com/markets/more-than-tariffs-behind-us-dollars-decline]^[2].

This crowding-out effect not only diverts resources from critical investments but also fuels inflationary pressures. As the Brookings Institution notes, while a full-blown fiscal crisis may not materialize in the next decade, the risk of political or economic missteps—such as a debt ceiling standoff or loss of credibility in fiscal policy—remains significant Assessing the risks and costs of the rising U.S. federal debt, [https://www.brookings.edu/articles/assessing-the-risks-and-costs-of-the-rising-us-federal-debt/]^[4].

Investor Reallocation: From Dollars to Alternatives

Global investors are already hedging against these risks by reallocating capital to alternative assets. Gold demand surged 16% year-over-year in Q1 2025, with investment demand outpacing jewelry and industrial uses Devaluation of the U.S. Dollar 2025 | Morgan Stanley, [https://www.morganstanley.com/insights/articles/us-dollar-declines]^[1].

Similarly, real estate and emerging markets have gained traction as safe havens, with flows into Asian and Latin American equities rising 12% year-to-date Devaluation of the U.S. Dollar 2025 | Morgan Stanley, [https://www.morganstanley.com/insights/articles/us-dollar-declines]^[1].

The Dollar Index Spot, a benchmark for the greenback's strength against major currencies, has fallen nearly 9% year-to-date, reflecting a shift in capital toward currencies perceived as more stable, such as the Swiss franc and the Japanese yen Devaluation of the U.S. Dollar 2025 | Morgan Stanley, [https://www.morganstanley.com/insights/articles/us-dollar-declines]^[1]. This reallocation is not without consequences: a weaker dollar could exacerbate inflation in import-dependent economies and trigger capital flight from U.S. Treasuries, further straining the Federal Reserve's ability to manage interest rates.

The Path Forward: Structural Reforms or Systemic Risk?

The U.S. faces a stark choice: implement structural reforms to stabilize deficits or risk a gradual erosion of the dollar's global dominance. The Penn Wharton Budget Model (PWBM) estimates that reforms such as immigration-driven labor market expansion and overhauling employer-sponsored health insurance taxation could reduce the deficit by $10 trillion over a decade Assessing the risks and costs of the rising U.S. federal debt, [https://www.brookings.edu/articles/assessing-the-risks-and-costs-of-the-rising-us-federal-debt/]^[4]. However, political gridlock and the short-term appeal of tax cuts—exemplified by the One Big Beautiful Bill Act—suggest that such measures remain aspirational.

For investors, the lesson is clear: the era of dollar hegemony is waning. While the greenback retains its status as the world's reserve currency, its perceived invulnerability is eroding. Diversification into non-dollar assets, gold, and inflation-protected securities is no longer a speculative bet but a defensive necessity.
