U.S. debt, inflation, and bond market signals

The market backdrop reflects that tension. U.S. CPI is running at 336.3, up about 40.7% from the level shown in the dataset two decades earlier, while the Federal Reserve’s policy rate has only recently eased to 3.88% from 3.63% in August, suggesting borrowing costs remain restrictive even after some relief. The 10-year Treasury yield, at 4.84% to 4.95% in the latest prints, is still high enough to keep pressure on duration-heavy assets and on governments that must refinance debt at materially more expensive levels than in the post-pandemic era.

For investors, the message is that inflation is no longer just a central-bank story; it is a fiscal one. High debt burdens make it harder for politicians to choose the unpopular medicine of spending restraint, tax increases or structural reform. That raises the odds of policy drift, currency debasement and repeated bouts of inflationary pressure — outcomes that tend to erode real returns and reward hard assets, inflation-linked securities and firms with pricing power.

Bond markets are already signalling caution. The iShares 20+ Year Treasury Bond ETF, TLT, has recovered to around 81.92 from a late-October low near 79.46, but remains below its 200-day moving average of 83.44, a sign that long-duration Treasuries have not fully repaired the damage from higher rates and sticky inflation expectations. The Bloomberg U.S. Aggregate Bond ETF, BND, is also only modestly firmer at 71.59, still below its 200-day average of 72.02. By contrast, the iShares iBoxx $ Investment Grade Corporate Bond ETF, LQD, has climbed back to 104.53 and is now above both its 50-day and 200-day moving averages, suggesting investors are more comfortable with corporate credit than with sovereign duration.

Adalytica’s CPI sentiment gauge is neutral at 45, while the U.S. dollar’s trade signals show “Extreme Fear,” a reminder that inflation and debt anxieties can show up in currency and rate markets well before they dominate official policy debate. The S&P 500’s trade signals remain neutral, but with awareness at extreme greed, indicating equities are still being priced with a degree of complacency relative to the fiscal risks Goodhart is pointing to.

The broader narrative is that democracy may be the binding constraint. Economically, the tools to contain inflation and debt are familiar. Politically, they are painful, and that is why markets should treat the current phase less as a clean disinflation story and more as a slow-moving test of whether elected governments can absorb the cost of stabilization without losing public support.
