US debt tops $40 trillion, pushing gold higher on fiscal risk

The US national debt topped $40 trillion in August, more than doubling from $19.4 trillion in 2016, as persistent federal deficits and compounding interest costs push investors toward gold and away from long-dated Treasuries.

"The national debt reaching $40 trillion is an interesting milestone but importantly, it's not one that changes our near-term outlook," said Vinny Amaru, global investment strategist at J.P. Morgan Wealth Management. "We still see the current economic backdrop as a positive one for corporate earnings potential and risk asset performance going forward."

The Treasury reported a $432.3 billion deficit in July, the highest monthly reading since March 2021, pushing the 2026 fiscal-year shortfall to nearly $1.8 trillion — exceeding the level recorded at the same time last year. The debt crossed $30 trillion in 2022, reflecting heavy pandemic-era stimulus, and has since accelerated as interest costs on existing debt add to annual borrowing needs. Gold has responded to the fiscal backdrop, with safe-haven demand strengthening as investors weigh the sustainability of US borrowing.

The milestone matters less as a single number than as a signal of the borrowing environment ahead. If investors demand higher compensation to hold longer-dated Treasuries, yields could remain elevated, raising borrowing costs across mortgages, corporate debt and other credit — while supporting gold as a hedge against fiscal and inflation risk.

Deficit at $1.8 trillion raises Treasury supply questions

The link between government borrowing and interest rates starts with supply and demand. When the federal government runs large deficits, it typically needs to issue more Treasury securities to finance the gap. If the supply of Treasuries rises, investors may require higher yields to absorb that additional issuance, especially if they are also weighing inflation risks and fiscal policy uncertainty.

The Fed has the most direct influence over short-term rates, while debt and issuance concerns tend to matter more for intermediate- and long-term yields such as the 10-year Treasury. Those yields help set the tone for borrowing costs across the economy, from mortgages to corporate debt.

Inflation is more complicated. A larger national debt doesn't automatically cause inflation — near-term price pressures are driven more by consumer demand, wages, energy prices and Fed policy. But if investors worry that persistent deficits will be hard to address through tax or spending changes, they may demand more protection against the risk of higher inflation over time, lifting inflation expectations embedded in long-term yields.

Term premium — the extra compensation investors demand to hold longer-dated Treasuries instead of rolling short-term bills — can also rise when uncertainty about inflation or fiscal policy increases. The last time the debt-to-GDP ratio expanded at a comparable pace was during the 2008 financial crisis and the pandemic, when the Fed's quantitative easing programs absorbed much of the additional issuance. This time, the Fed is actively shrinking its balance sheet, leaving the private market to absorb a larger share of Treasury supply.

Gold's safe-haven bid strengthens

For investors, the effect of debts and deficits could be most visible in yields. When longer-term Treasury yields rise or become more volatile, bond prices can move sharply — especially longer-duration bonds, which are sensitive to changes in interest rates. At the same time, higher yields can improve future income potential for bond investors.

Higher long-term yields can also raise the discount rate investors use to value future earnings, putting pressure on equity valuations. In such an environment, markets may place greater value on companies with durable cash flows, pricing power and balance-sheet strength.

Gold has emerged as a key beneficiary of the fiscal backdrop. The metal's role as a store of value tends to strengthen when investors question the long-term purchasing power of fiat currencies or the sustainability of government debt. With the US running deficits near $1.8 trillion annually and interest costs compounding, gold's appeal as a hedge against fiscal and inflation risk has grown.

Investors may want to recheck duration exposure in bond allocations, diversify sources of return and avoid portfolios that depend too heavily on one macro outcome, such as rates falling quickly or inflation cooling. Portfolio decisions should remain anchored in goals, time horizon, liquidity needs and risk tolerance.
