To assess true macroeconomic stability amid market noise, investors should monitor four specific signposts: inflation expectations, government debt volatility, U.S. dollar valuation, and credit market stress. As long as these core indicators remain calm, the fundamental case for market strength holds.
A key risk for 2026 is the disconnect between stretched market valuations (e.g., tight credit spreads in the 1st percentile) and a macroeconomic environment that doesn't feel late-cycle. This tension suggests that even if growth drives equities higher, it could be accompanied by increased volatility or widening credit spreads.
When bond prices exhibit short-term mean reversion (up one day, down the next), it's a quantitative sign of deep uncertainty. This reflects the market and the Fed struggling to choose between fighting inflation and addressing weakening employment, leading to no clear trend until one indicator decisively breaks out.
Contrary to conventional wisdom, re-accelerating inflation can be a positive for stocks. It indicates that corporations have regained pricing power, which boosts earnings growth. This improved earnings outlook can justify a lower equity risk premium, allowing for higher stock valuations.
Despite recent concerns about private credit quality, the most rapid and substantial growth in debt since the GFC has occurred in the government sector. This makes the government bond market, not private credit, the most likely source of a future systemic crisis, especially in a rising rate environment.
Policymakers can maintain market stability as long as inflation volatility remains low, even if the absolute level is above target. A spike in CPI volatility is the true signal that breaks the system, forces a policy response, and makes long-term macro views suddenly relevant.
In a regime of fiscal dominance, where government spending dictates policy, the currency, not bond yields, becomes the primary release valve for economic pressure. While equities and yields may appear stable, the true cost of stimulus will be reflected in a devaluing dollar, a risk often overlooked by bond vigilantes.
Despite investor fears fueled by geopolitics and rising gold prices, key market indicators—inflation expectations, rate volatility, USD valuation, and credit spreads—show surprising stability. This suggests the underlying economic foundation is stronger than negative sentiment implies, supporting a positive market outlook for now.
The Federal Reserve can tolerate inflation running above its 2% target as long as long-term inflation expectations remain anchored. This is the critical variable that gives them policy flexibility. The market's belief in the Fed's long-term credibility is what matters most.
The central strategy in macroeconomics is to stifle volatility in foundational markets like bonds and foreign exchange. This engineered stability allows nominal GDP to outpace debt, effectively devaluing it over time. This delicate balance is most vulnerable to unpredictable geopolitical shocks that can shatter the low-volatility regime.
According to Keith McCullough, historical backtesting reveals the rate of change of the U.S. dollar index is the most critical macro factor for predicting performance across asset classes. Getting the dollar right provides a significant edge in forecasting moves in commodities, equities, and other global markets.
