With U.S. government debt recently surpassing $40 trillion and long-term Treasury yields remaining elevated, investors are reassessing how deficits, inflation and future borrowing needs could affect asset prices. In its third-quarter 2026 investment review, Regency Wealth Management said market attention may shift between artificial intelligence, inflation, geopolitics and government spending, but investment decisions still come back to economic growth, corporate cash flow, valuations and balance-sheet strength.
Stocks and bonds diverge in the third quarter
Global markets navigated resilient economic growth, cooling inflation and persistently high long-term interest rates. Consumer confidence weakened overall, but the market backdrop remained relatively steady. Concerns about fiscal deficits and the transparency of monetary policy continued to shape investor views.
The S&P 500 gained 2.3% in the third quarter, while the tech-heavy Nasdaq 100 Composite rose 0.4%. Small caps lagged: the S&P 600 fell 8.3%. The MSCI ACWI ex-US Index, which tracks international stocks outside the United States, added 0.5%.
Fixed income came under pressure, with the Bloomberg U.S. Aggregate Bond Index down 3.5%. Investors continued to reassess interest rates, inflation and the Federal Reserve’s policy path. The 10-year Treasury yield climbed sharply in September, ending the quarter at 5.29%, up from 4.47% at the end of the previous quarter. The 30-year yield rose to 5.64%, from 4.95%.
Corporate earnings growth remained relatively solid. Companies with stronger cash flow and disciplined capital allocation were better positioned to win market support.
Three ways to ease the burden of U.S. debt
With U.S. debt above $40 trillion, the debate is not just about its absolute size. Investors are also weighing debt relative to the size of the economy and the government’s ability to service and refinance its obligations. Regency Wealth Management outlined three approaches that have historically helped countries manage debt burdens.
Grow the economy faster than the debt
The most favorable scenario is for economic growth to outpace debt growth. That would not require the government’s total debt to fall: if gross domestic product grows faster, debt can decline as a share of the economy. After World War II, a prolonged period of U.S. economic expansion helped improve the debt-to-GDP ratio without relying entirely on sharp fiscal adjustments.
Some investors see potential productivity gains from artificial intelligence and other technological advances as a possible route to stronger growth. The extent to which these technologies will lift productivity over the long term remains uncertain. Sustained improvements in productivity and growth could support corporate earnings, the tax base and the broader economy, helping to make debt more manageable.
Rein in deficits through fiscal policy
A second route involves slowing spending growth, raising revenue or making structural changes. The basic arithmetic is straightforward: when spending persistently exceeds revenue, deficits add to debt. Slowing deficit growth can in turn curb the pace of debt accumulation.
Long-term debt stability generally requires some degree of fiscal discipline, but there is no broad agreement on the right mix of policies. Tax increases, benefit cuts and reductions in government spending can carry short-term economic and social costs, making consensus difficult to achieve.
Inflation can reduce debt’s real value
A third mechanism is less often discussed publicly, but has appeared in financial history. When inflation exceeds the government’s borrowing costs, the real value of debt may decline over time. Governments collect taxes in nominal dollars, so rising wages, profits and asset prices can lift tax receipts, while the principal on existing fixed-rate debt does not automatically rise with inflation.
That dynamic can put pressure on savers and bondholders by eroding the purchasing power of fixed cash flows. Regency Wealth Management did not predict that the United States would pursue this route; it listed inflation as one mechanism that has historically helped highly indebted countries adjust.
| Route | What it means | Potential investor implications |
|---|---|---|
| Economic growth | GDP grows faster than debt | Typically supports equities, corporate earnings and long-term wealth creation |
| Fiscal discipline | Deficits shrink over time | Can improve fiscal stability, but may slow growth in the short term |
| Inflation | Reduces debt’s real value | Can pressure savers and bondholders while lowering the real burden of debt |
Long-term yields reflect views on the fiscal outlook
Investors are closely watching 10- and 30-year Treasury yields because long-term rates are not set by Federal Reserve policy alone. They also reflect expectations for economic growth, inflation, future government borrowing and fiscal sustainability.
When investors believe the economy can keep growing and public finances can stabilize, long-term yields tend to face less pressure. Fears of persistent inflation, widening deficits or heavier future issuance can lead investors to demand higher yields in return. Long-term rates therefore offer one gauge of how markets view the U.S. fiscal trajectory.
Regency focuses on cash flow and balance-sheet strength
Regency Wealth Management said its investment approach has not changed with shifting market narratives. Whether investors are focused on artificial intelligence, inflation, deficits or geopolitics, the firm continues to assess companies on fundamentals, cash flow, valuation and balance-sheet strength.
With long-term rates elevated, the cost of capital is no longer close to zero, making business quality and operational resilience more important. In fixed-income portfolios, current yields also offer an allocation backdrop rarely seen over the past decade. High-quality bonds and U.S. Treasuries can provide income while retaining their traditional role as portfolio stabilizers.
The firm said portfolios should not depend on a single economic forecast. Instead, diversification can help address different growth, inflation and interest-rate scenarios. Its management team includes Managing Partner and CEO Timothy G. Parker; Managing Partner and Chief Compliance Officer Mark D. Reitsma; Managing Partner and Chief Operating Officer Bryan D. Kabot; Partner and Wealth Advisor Mark M. Andraos; Managing Director of Operations Scott Drown; and Assistant Portfolio Manager Ryan Hulsebos.
U.S. debt and long-term Treasury yields remain important market indicators, but debt problems are rarely resolved quickly. For investors, the more immediate measures to track include real economic growth, corporate earnings, government borrowing costs, inflation and yield changes across maturities.
