US national debt hits $40 trillion as advisors weigh portfolio risk

The United States' national debt has climbed past $40 trillion, yet the stock market keeps setting fresh records – a disconnect that is forcing financial advisors to decide how much weight Washington's fiscal trajectory should carry in client portfolios. The Congressional Budget Office projects debt held by the public will keep rising through the next decade, and that math is now part of everyday conversations between advisors and clients about duration, equity concentration and long-term planning.

For most advisors interviewed, the debt load itself is not triggering wholesale portfolio changes. What is changing is how closely they are watching the cost of servicing it – and what that means for bond allocations, equity valuations and, eventually, entitlement programs.

Debt levels alone aren't moving portfolios

Matt Dmytryszyn, chief investment officer at Composition Wealth, said the size of the deficit has to be viewed in context rather than isolation. The U.S. debt-to-GDP ratio, he noted, is comparable to that of most other major global economies, and he has not made major portfolio adjustments as a result of the deficit alone. He has, however, become more attentive to exposure on the long end of the Treasury curve.

"The current confidence in U.S. equities is tied to the strength of corporate earnings, which have not only grown stronger during 2026 but have also seen a broader-based acceleration across most sectors of the economy. Further, while the U.S. deficits remain elevated, we are also seeing other major economies expand their fiscal spending. Thus, rising deficit levels are not just a U.S. phenomenon," Dmytryszyn said.

He added that if the earnings-driven rally continues, it would support stronger tax revenue – though he expects the debate over entitlement funding to intensify heading into the next election cycle. "That said, the fiscal problems do need to be addressed and we believe catalysts exist that could spur some discussion and debate on this coming out the 2028 election, given projections that Social Security and Medicare funding are likely to face greater challenges at this time," Dmytryszyn said. Advisors have already been preparing clients for the possibility of reduced Social Security benefits well ahead of that political timeline.

Josh Strange, president and founder of Good Life Nova, frames the debt as both a fiscal and a moral issue, but says it does not drive short-term investment decisions. "As an advisor, I focus on what our clients can actually control. Federal spending and the national debt are beyond any individual investor's influence, so we treat them as long-term structural risks instead of letting them drive short-term investment decisions. One likely result is that interest rates may stay higher for a longer period, since investors want more compensation for inflation and fiscal risk. This situation creates chances to earn better yields and highlights the value of diversifying with high-quality fixed income. These benefits are especially important now, as major equity indexes are heavily concentrated in a small number of large technology companies," Strange said.

Interest cost risk shapes duration bets

Jim Worden, chief investment officer at The Wealth Consulting Group, said the debt level itself does not change how he approaches portfolio construction, but the market's reaction to it does. He remains positioned closer to the front end of the yield curve, with limited exposure to longer maturities – a stance shared by advisors closely tracking the 10-year Treasury yield amid ongoing inflation data.

"Should inflation related to higher energy prices persist, which we don't believe it will, we could see longer-term rates move higher and the Fed become more hawkish about raising rates on the short end. If that happened, we could reduce duration and exposure to the long end. We would also be looking at what point rates have moved too high. The Federal Reserve often overshoots to both the upside and the downside with regard to hiking or cutting rates. Should we find ourselves with weaker-than-expected employment and inflation trending lower, adding some exposure on the long end could be value additive. As it relates to our debt, the more immediate concern is whether the growing interest burden eventually weighs on economic growth, reduces fiscal flexibility, or causes investors to demand a higher premium to own longer-term Treasury debt," Worden said.

Worden said his longer-term consideration is whether the U.S. dollar retains its role as the world's reserve currency – a status he expects to persist even as debt grows.

Equities still reflect earnings, not deficits

Strange said U.S. stocks remain supported by strong corporate earnings, ongoing innovation and the underlying strength of many American businesses, and that the debt burden does not automatically translate into an immediate hit to profits or share prices. He pointed to a degree of lingering caution among investors as a healthy sign. "In short, investors seem to be separating the government's financial situation from the outlook for individual companies. The debt burden is important, but its impact on investors may be less direct and may develop more slowly than headlines suggest," Strange said.

He was clear, though, that the rally does not signal an easy path out of the debt burden. "If anything, the rally shows why it is important to separate short-term market gains from long-term fiscal health. We still see good reasons to invest, but we also know that markets might not fully reflect the risks tied to the country's long-term debt path," Strange said.

Worden pointed to a structural source of equity demand that persists regardless of the fiscal backdrop: ongoing retirement-account contributions. "Despite concerns about the debt burden, we do not believe the debt by itself represents an imminent catalyst for a major equity market decline. For equity investors, the debt becomes more consequential if it ultimately leads to structurally higher interest rates, higher taxes, weaker economic growth, or some combination of the three. Investors' primary concern right now is how long profits and revenue can keep growing, what the ultimate source of that growth is, and whether it is sustainable," Worden said. Similar caution has surfaced in Wells Fargo Investment Institute's recent analysis of the country's debt trajectory, which described the path as serious but not yet a crisis for markets.

What advisors are watching next

Worden said he expects both the market and the debt to keep growing in tandem, absent structural changes to spending or revenue. "We don't believe we will necessarily grow our way out of the debt without measures also being put in place to cut spending or increase tax revenue. We don't know when the next recession will be, and we certainly aren't predicting one anytime soon, but a future period of weaker economic growth and lower interest rates could give the Treasury an opportunity to roll maturing debt into longer-term securities at more favorable rates. That could help reduce future interest costs and refinancing risk. Ultimately, the level of debt is only part of the equation. What matters is the cost of servicing that debt relative to the growth of the economy. Lower interest costs, cuts to unnecessary spending, stronger economic growth, and increases in revenue could all help make the debt burden more manageable over time," Worden said.

For now, advisors interviewed agree on one point: the $40 trillion figure is a milestone worth noting, but not, on its own, a reason to rewrite a client's investment plan.
