Marking the 250th anniversary of the US Declaration of Independence, a Deutsche Bank Research Institute report examines how the US evolved from a relatively small nation into a global superpower and whether that position can be sustained amid emerging structural headwinds.
The report highlights both enduring strengths and rising vulnerabilities in the global order.
“Since the United States’ founding, the country has achieved remarkable economic success on a whole range of metrics,” the report said, citing population growth, US GDP growth, long-term equity performance and the absence of hyperinflation.
Deutsche Bank attributes this success to a reinforcing set of long-term advantages, including institutional stability, deep capital markets, abundant energy resources, favourable geography, large-scale domestic demand and a globally dominant currency system. These factors, it argues, combine to support sustained innovation, investment and productivity growth across multiple economic cycles.
“It is also important to note that these advantages do not play out individually, but are mutually reinforcing, with the interaction between them allowing the US to benefit from network and externality effects that few if any countries can match.”
However, the report stresses that this success has not followed a straight path. US history has been shaped by major disruptions and recoveries, including the world wars, the Great Depression, the inflationary shocks of the 1970s and the global financial crisis. In each case, the US ultimately returned to outperformance, driven by adaptability and policy flexibility.
Entering the 21st century, the US faces a new set of challenges: strategic competition from China’s economic and technological rise, elevated public debt, widening fiscal deficits, demographic ageing and a gradual erosion of aspects of dollar dominance.
Despite this, Deutsche Bank notes that the US economy rebounded rapidly from the pandemic, supported by exceptionally large fiscal and monetary stimulus, significantly exceeding that deployed after the 2008 global financial crisis.
“Moreover, recent years have seen the US at the forefront of AI developments, raising hopes of a new productivity surge, with its lead extending over the other advanced economies. So yet again today, the US has emerged from a rockier period around the financial crisis and its aftermath, into a relatively strong position that includes the highest GDP per capita of any G7 country,” the report said.
Still, the bank argues that today’s challenges feel more “acute”, particularly given China’s rise as a systemic rival.
“China has already overtaken the US on manufacturing output, merchandise trade, and GDP (on a PPP basis), and is rapidly closing the gap in advanced technologies and semiconductors. The US retains decisive leads in nominal GDP, capital markets depth, the dollar system, and frontier innovation, but the gap has narrowed substantially,” the report said.
China is also expanding its influence in global manufacturing, low-cost energy production and the international role of the RMB.
“The emergence of China comes as the rules-based international system designed and led by the US for eight decades is under strain from multiple directions.”
The report also points to growing uncertainty around recent US policy decisions, which it says are contributing to questions about the durability of the global order and the US dollar’s reserve status.
“The dollar’s share of global reserves has fallen from roughly 72 per cent to 58 per cent over two decades – a gradual decline rather than a collapse, but a clear trend nevertheless. The reduction has accrued to a basket of “non-traditional” reserves and to gold, which has seen the largest central bank buying programme in over half a century.”
However, Deutsche Bank emphasises that no credible alternative is currently positioned to replace the dollar.
The more plausible risk over the next decade, it argues, is gradual erosion rather than abrupt displacement.
With US debt-to-GDP ratios approaching record levels, fiscal space to respond to future shocks is becoming more constrained. The report suggests that the coming decade will test US adaptability and the ability of its political system to manage overlapping pressures.
Deutsche Bank identifies the fiscal trajectory as a key macroeconomic risk and a potential accelerant of dollar erosion, particularly for institutional investors assessing long-term exposure to US assets.
Despite these headwinds, the report concludes that the US is likely to remain the world’s leading economy for the foreseeable future, supported by its innovation edge, deep financial markets and capacity to absorb shocks. However, this outcome depends on whether fiscal, political and social pressures can be managed without undermining institutional strengths.
“The US should remain the world’s largest economy well beyond the critical decade coming up … There is further upside potential to productivity growth from the US’ significant lead on AI. This AI boom is the latest expression of the US capacity for reinvention that stretches back through its history: a willingness to embrace disruptive, capital-intensive technology and absorb the dislocation it brings.”
Deutsche Bank ultimately maintains that the US remains the world’s premier investment destination.
“An investor into the US buys a bundle that is hard to replicate – productivity leadership, the deepest and most liquid capital markets in the world, the rule of law that underpins them, and the flexibility conferred by the dollar’s reserve role.”
