How to Invest Before the Debt Crisis Breaks

A practical portfolio framework for a slow-building risk that is likely to resolve quickly when it finally does.

Article 3 of 3 in the US Debt Series

Key Takeaways

• The S&P 500 rising and US debt being dangerous are not contradictory — they operate on different timeframes.

• The zero-rate floor that powered pure US growth portfolios from 2010 to 2021 has structurally risen and is unlikely to return without a recession.

• History suggests sovereign debt problems build slowly but resolve through sharp, discrete events — not gradual declines.

• Long-duration Treasury bonds are the asset most directly exposed to a sharp repricing event.

• A calibrated portfolio keeps high-conviction growth exposure while adding gold, short-duration bonds, and international diversification as structural insurance.

Why Is the Stock Market Still Going Up?

If the United States is on an unsustainable fiscal path, why is the S&P 500 near all-time highs? This apparent contradiction is the first thing investors need to understand — because the answer shapes everything else.

The stock market does not price the government's balance sheet. It prices corporate earnings. And corporate earnings have been growing strongly, driven by the AI investment supercycle, margin expansion from technology, and the dominance of a small number of globally powerful companies. The federal government's debt is a drag on the economy's long-run growth potential — but large-cap technology companies can grow earnings faster than the broader economy, regardless of what is happening in Washington.

More importantly, markets price what they can see over the next 12 to 18 months. A fiscal crisis that is a genuine risk over 20 years is nearly invisible in today's stock valuation. Distant risks are systematically underpriced by markets until they become near-term risks — and then they are repriced very suddenly.

This is precisely why J.P. Morgan Asset Management described the US fiscal situation as "going broke slowly." Slowly enough that AI earnings momentum, liquidity, and the absence of a credible alternative keep winning quarter by quarter. But the direction is not ambiguous.

What Actually Changed

The key question for investors is not whether the debt is dangerous — it is whether the environment has changed in ways that require a portfolio adjustment. On that question, the answer is yes, and it comes down to one variable: interest rates.

From 2010 to 2021, the Federal Reserve held rates near zero. This created an extraordinary environment for growth equities: future earnings were discounted at negligible rates, making the present value of distant profits very high. It also meant the government's interest bill stayed low despite rising debt. Bonds offered almost no yield, so there was no competition for equities.

That environment is over. The 10-year Treasury now yields approximately 4.5%. The federal government is paying roughly $1 trillion per year in interest — already more than it spends on national defense. The Fed no longer has room to cut rates aggressively in a downturn without reigniting inflation. And the One Big Beautiful Bill Act, signed in July 2025, added $4.2 trillion to the projected debt, locking in a structurally larger interest burden for years.

The rules have changed. Not dramatically or suddenly — but enough to matter for how a long-term portfolio should be constructed.

The Rate Conflict Investors Need to Understand

Here is the central tension that will define the investment environment for the foreseeable future. The US faces two problems that require opposite interest rate responses.

The debt burden wants rates down. The government is paying $1 trillion per year in interest and refinancing trillions of dollars of maturing debt every year. Lower rates reduce that burden. This is why there is persistent political pressure on the Federal Reserve to cut.

Inflation wants rates up. The government is simultaneously spending $1.8 trillion more per year than it collects in taxes. That deficit spending is inherently inflationary. Core inflation as of mid-2026 is running at 3.3% — above the Fed's 2% target and moving in the wrong direction. The Fed's job is to keep rates elevated to prevent inflation from becoming entrenched.

There is no clean resolution to this conflict. If the Fed holds firm on inflation, the government's interest bill continues to compound. If the Fed eventually cuts to ease the fiscal burden, inflation risks returning — and real returns on most investments erode. This is what economists mean when they warn about "fiscal dominance": the point at which the debt is so large that it begins to constrain monetary policy.

As of mid-2026, the inflation side of this conflict is winning, not the fiscal-relief side. Core inflation has been running near 3.4%, the highest reading since 2023, and markets are now pricing meaningful odds of additional Fed rate hikes rather than cuts. This is, on balance, a reassuring signal: it means the Fed is currently prioritizing its inflation mandate over accommodating the government's borrowing costs, which is the opposite of fiscal dominance. But it also means the relief many investors are hoping for — lower mortgage rates, cheaper financing, looser conditions — is not imminent.

For investors, the practical implication is that neither direction is unambiguously good. A portfolio needs to be resilient to both outcomes, not positioned for just one.

Understanding Bonds: Not All Are Equal

One of the most important distinctions in this environment is between different types of bonds — because the "inflation and financial repression" resolution path destroys some bonds and protects others.

Long-duration Treasury bonds (20–30 year): These are the most vulnerable. If you lend the government money for 30 years at 4.6% and inflation runs at 4% for a decade, your real return is nearly zero. The government has effectively borrowed real purchasing power and repaid cheaper dollars. This is the wealth transfer mechanism that governments use to inflate away debt — and long-duration bondholders are the ones who pay.

Short-duration Treasuries (1–3 year): These are largely protected. Your money comes back in 1 to 3 years. You reinvest at whatever rates prevail — including higher rates if inflation has pushed them up. The erosion window is too short for significant damage.

TIPS — Treasury Inflation-Protected Securities: These are specifically designed for this environment. The principal automatically adjusts upward with inflation. If inflation runs at 5%, your principal grows by 5%. This is the only bond structure that actively fights back against the resolution path.

The practical rule: if and when you add fixed income to your portfolio, go to TIPS or short-duration bonds. Avoid long nominal Treasuries in a structurally high-inflation environment. The 30-year Treasury is precisely the instrument a government inflates away.

One Illustrative Portfolio Example

What follows is one example of how an investor with a long horizon, high risk tolerance, and strong conviction in technology and AI might think through these tradeoffs — not a recommendation. The specific tickers, weights, and choices below are illustrative only, meant to show the reasoning process rather than a model to copy. A different investor with different goals, risk tolerance, or views on emerging markets could reasonably build something quite different from the same set of facts. As always, this is not financial advice — see the disclaimer at the end of this article.

Example Allocation

The Logic Behind Each Position 

VONG — 40%

Vanguard Russell 1000 Growth ETF. Broad US growth exposure with the AI-era concentration already built in. This remains the primary return engine. The trim from a hypothetical 50% starting point funds the additions below without abandoning the core thesis.

VGT — 30%

Vanguard Information Technology ETF. Pure technology concentration for the highest-conviction portion of the portfolio. Slightly reduced because the overlap with VONG is high — you are not losing meaningful diversification by trimming, just reducing concentration in the same underlying names.

IAU — 15%

iShares Gold Trust. This is the single highest-priority adjustment in the current environment. Gold performs best when real interest rates are low or negative, when the dollar weakens, and when inflation expectations rise. All three are plausible multi-year outcomes under the fiscal repression scenario. Moving from 10% to 15% shifts gold from a tactical hedge to a structural position — which is where it belongs given the analysis above.

International developed or total-international markets — 10%

This is a case where reasonable investors genuinely differ, and it's worth naming both options rather than presenting just one. Vanguard's VEA tracks developed markets only — roughly 3,900 stocks across 24 countries including Japan, the UK, Germany, France, Switzerland, and Canada, with no emerging-market or China exposure, at a 0.03% expense ratio. Vanguard's VXUS tracks the entire world outside the US, including emerging markets — about 8,500 holdings, roughly 25% of which are emerging-market companies including China, India, and Brazil, at a 0.07% expense ratio.

Both funds serve the same basic purpose discussed in this series: a hedge against a weakening dollar, since foreign assets become worth more in dollar terms if the dollar declines, and exposure to international valuations that are meaningfully cheaper than the US on average. The genuine tradeoff is that VEA is more stable and avoids emerging-market and China-specific risk, while VXUS is more diversified and gives exposure to faster-growing emerging economies, at the cost of additional volatility and geopolitical risk. Some investors specifically want emerging-market exposure as part of their thesis; others specifically want to avoid it. This example shows VEA, reflecting one reasonable preference for stability given the concentration already present elsewhere in the example portfolio — but an investor who wants broader emerging-market exposure could reasonably substitute VXUS, or blend the two, without changing the underlying logic of this series.

TIPS — Staged Entry

In this example, TIPS are not added immediately, reflecting a long horizon, strong equity conviction, and the discussion elsewhere in this series about timing. Rather than trying to time an entry off daily market data — which is not realistic for most retail investors to track consistently — a more workable approach is to revisit the question periodically, such as during an annual portfolio review, considering whether inflation has stayed uncomfortably high for an extended period, whether personal circumstances have changed, or whether bonds generally look more attractive again. Using short-duration vehicles like VTIP or broader-duration vehicles like SCHP over long nominal Treasuries is one reasonable approach among several, not a specific timing recommendation.

When to Reconsider TIPS — A Realistic Approach

Precisely timed entry signals based on daily bond yields are not realistic for most people to track, and a missed signal is not a small miss — it defeats the purpose of having a signal at all. A more workable approach for a retail investor is a periodic check-in, ideally as part of a regular portfolio review (once or twice a year, or with a financial advisor), rather than ongoing market monitoring.

How This Portfolio Performs Across Scenarios

The Bottom Line

The US debt situation is serious, directionally clear, and politically intractable in the near term. But "going broke slowly" is not the same as "going broke now." The AI earnings cycle is real, the reserve currency buffer remains intact, and there is no credible alternative for global capital to flee to.

The right investor response is not panic, and it is not complacency. It is calibration. Stay long the growth cycle. Add structural insurance against the resolution path — inflation and financial repression — that requires the least political courage and is therefore the most likely. Understand which bonds help and which ones hurt. And monitor the leading indicators rather than the debt ceiling headlines.

The investor who does this does not need to predict which scenario plays out. They are positioned to compound through whichever one arrives.
