The U.S. National Debt Just Surpassed $40 Trillion. Here's What This Means for Your Portfolio in 2026 and Beyond.

Besides the artificial intelligence trade, investors have been obsessed with any macroeconomic news that hits headlines. And it's hard to find a story in recent weeks that captured the market's attention like the U.S surpassing $40 trillion in gross federal debt. By any measure, this is an absolutely mind-boggling number.

The debt balance has expanded by 377% in the past two decades. And it currently represents 123% of the country's total GDP figure. The Congressional Budget Office estimates that it will continue climbing, reaching $64 trillion by 2036.

Investors had better get used to hearing more about the U.S. national debt problem. Here's what this macro trend means for your portfolio in 2026 and beyond.

Nothing will change

The U.S. has the world's largest and most advanced economy, driven by dominance in the technology sector. It controls the global reserve currency in the dollar. And it has the most robust and liquid capital markets. These advantageous traits support the argument that the nation can keep borrowing indefinitely.

Of course, this can continue only as long as buyers of Treasuries trust that they will get paid back. So far, this hasn't been an issue. And things that appear unsustainable can go on a lot longer than people anticipate.

It makes sense for the government to embark on stimulative measures during recessions or other adverse shocks. This was precisely what happened during the global financial crisis toward the end of the 2000s, and to help boost the economy when the COVID-19 pandemic hit. The government steps in to keep things running.

What's interesting to see, though, is that the debt burden has kept rising even though the economy is on solid footing. Through the first 10 months of fiscal 2026, the Treasury Department ran a deficit of $1.8 trillion, 10% higher than in the same period last fiscal year. The U.S. spends more on interest payments than it does on national defense.

No matter what politicians say, the government isn't able and willing to cut spending. Just look at the DOGE (Department of Government Efficiency) initiative, which was by any account a failure.

And raising taxes isn't a popular campaign platform, unless politicians want to increase their chances of losing. This means that the debt will keep rising. Furthermore, this supports elevated inflation and interest rates. This will certainly be true relative to the environment we witnessed during much of the 2010s.

Own inflation beneficiaries

The investment implications are clear. In this kind of macro backdrop, investors should favor high-quality businesses, particularly those that have pricing power and impressive financials. This isn't necessarily a buy recommendation. But these are companies to dig further into here.

Apple (NASDAQ: AAPL) comes to mind. Its brand resonates strongly with consumers around the globe. Its hardware devices are always in demand, commanding premium prices. And the business is one of the most profitable in the world. On $364 billion in revenue through the first nine months of fiscal 2026, Apple raked in $110 billion in free cash flow.

Another great example is Ferrari (NYSE: RACE). This company doesn't behave like a typical mass-market car manufacturer. Ferrari intentionally caps supply, supporting robust demand and pricing power for its luxury vehicles. And its operating margin was a stellar 31% last quarter.

Investors might not view Visa (NYSE: V) and Mastercard (NYSE: MA) as having pricing power. However, they are certainly beneficiaries of inflation. As consumers are forced to spend more on goods and services, these payment networks are able to process higher volumes, which translates to revenue growth. It also helps that they are incredibly profitable, with net income margins that have averaged more than 45% in the past five years.

These four businesses are set up to continue thriving in the face of mounting U.S. national debt.
