U.S. Exceptionalism: A Matter of Perspective
On May 9, 2025, the financial world sent a collective gasp as Warren Buffett, the legendary investor known for his unwavering faith in the resilience of the American economy, announced his plans to step back from Berkshire Hathaway’s management. This announcement raised eyebrows and questions, particularly about the long-term durability of U.S. market dominance. In a striking shift, Buffett’s portfolio now sports a historic allocation of non-U.S. investments and more than half of it in cash. Yet, at the Milken Institute Global Conference just two days later, Treasury Secretary Scott Bessent passionately rallied for a U.S.-centric investment approach, simplifying American economic history into five words: “Up and to the right.” In this turbulent landscape, investors find themselves at a crossroads, weighing Buffett’s caution against Bessent’s optimism.
The fading strength of the U.S. dollar might indicate that both Buffett and Bessent could be right—U.S. exceptionalism may hinge on an investor’s perspective. For domestic investors, U.S. assets could continue thriving in dollar terms, even while foreign investors grapple with currency risks that could hamper their returns. The phenomenon here resembles something out of quantum physics, where observation alters reality: the status of U.S. economic leadership may depend on where you’re standing.
The Drivers of U.S. Investment Dominance
For the past decade, U.S. investment outperformance has thrived on three primary engines, all of which warrant a closer examination through a conservative lens.
1. Unprecedented Fiscal Policies
The first significant driver of U.S. outperformance is its expansive fiscal policy. Under President Trump, the 2017 Tax Cuts and Jobs Act slashed taxes, spurring short-term economic growth, while President Biden’s Inflation Reduction Act ramped up government spending. The outcome? A staggering budget deficit that ballooned from 3.5% of GDP in 2015 to an alarming nearly 7.5% in 2024. The contrast between U.S. fiscal health and that of other G7 nations is irrefutable, where the average budget deficit hovers at just 3.7% of GDP. With Trump’s policies likely paving the way for further fiscal largesse, the prospect for financial prudence looks dim.
2. Leadership in Technology
The second engine propelling U.S. financial markets has been extraordinary technological innovation. The ‘Magnificent Seven’ stocks—Microsoft, Apple, Nvidia, Amazon, Alphabet, Meta Platforms, and Tesla—account for about a third of the S&P 500’s market capitalization. Optimists assert that America’s technological prowess will continue to drive economic growth, while skeptics warn of an impending bubble akin to the dot-com crash. While U.S. equities have experienced ups and downs in 2025, tech investments remain a central player in the economy, highlighting the strength of American innovation. However, we must tread carefully and consider whether these companies are genuinely robust or merely riding on borrowed time.
3. The Bull Market in the Dollar
Lastly, the long-standing appreciation of the U.S. dollar has acted as a significant support for U.S. market outperformance. For over a decade, the dollar gained nearly 30% against the euro, benefiting foreign investors and boosting returns for those invested in U.S. financial assets. In stark contrast, 2025 has seen a significant decline in the dollar’s value, with reports indicating a drop of 8% this year alone. The broad international investment ledger suggests major liabilities for the United States, with net international investment liabilities swelling to nearly 90% of GDP. This shift could significantly affect foreign investors, making U.S. assets less attractive amid a declining currency.
The Question at Hand: Is U.S. Outperformance Over?
The pressing question remains: Is it worth investing in U.S. markets, even if they are currently fueled by only two out of their three historical engines? The answer appears to hinge on one’s vantage point. For those within U.S. shores, investments may still perform well in nominal dollar terms, boosted by continuing American technological advancements and potentially extravagant fiscal stimuli. For international investors, however, a bear market for the dollar spells trouble, one that could render lucrative U.S. assets substantially less appealing.
Historical precedence suggests these dichotomous conditions can persist for extended periods, as evidenced by the S&P 500’s performance leading up to the financial crisis in 2008. Even during a dollar downturn, U.S. assets remained attractive to many institutional investors. As Buffett himself starkly advised, avoiding detrimental currencies might be a prudent path forward in these uncertain times. In conclusion, the fate of U.S. investment outperformance may not only reflect the fundamentals but may also align with the perspectives of both domestic and international stakeholders. Navigating this intricate web will require a keen eye and an unwavering commitment to sound financial principles.
Investors looking to weather any monetary storm must remember: tradition, prudence, and a healthy skepticism can prove to be the guiding lights in these uncertain waters.
