The Era of Waller: Are High Interest Rate Fluctuations the New Normal?

After the Federal Reserve abandoned forward guidance, the interest rate market is entering an era of high volatility.

Under Waller's leadership, the Federal Reserve has abandoned forward guidance, pushing the interest rate market into a structurally high-volatility era. The lack of a clear policy response framework, combined with the persistent rise in global inflation, is enhancing the active pricing power in the bond market, leading to interest rate fluctuations that will continue to suppress risk appetite in the stock and credit markets.

The July FOMC meeting epitomized this crisis of confidence.

The Federal Reserve remained inactive but failed to clearly articulate the conditions that would trigger interest rate hikes. Waller only hinted that rising real yields are already exerting a tightening effect, without explaining why the current constraints are sufficient. Following the meeting, long-term U.S. Treasuries were sold off, and implied interest rate volatility surged, revealing a negative feedback loop between policy and market reactions.

This dynamic is forming a vicious cycle: the market demands higher yield compensation due to weakened inflation credibility, while the Federal Reserve views rising yields as a substitute for policy action rather than taking proactive measures. This, in turn, prompts traders to demand higher term premiums, further pushing up long-term rates.

Bloomberg macro strategist Michael Ball pointed out that until Waller clearly articulates his policy response framework for the current structural economic environment, high volatility will continue to be a prominent feature of this era, suppressing stock and credit risk sentiment.

Trust Deficit: Policy Ambiguity Causes Market Pricing Chaos

Historical experience shows that low interest rate volatility resulting from stable Federal Reserve policy expectations can provide strong support for stock and credit markets, allowing investors to focus on fundamentals of earnings and growth rather than risks of policy missteps. This logic was fully validated by the end of 2025—when policy path expectations stabilized, interest rate volatility declined, providing strong tailwinds for equity and credit markets.

However, the current situation is starkly different. Market participants are concerned that a series of recent actions by the Federal Reserve are giving rise to a new volatility mechanism. Although interest rate volatility has retreated from the highs seen during the oil price surge in March, the overall level remains elevated and is highly sensitive to macro data.

In the absence of a clear policy response function, every economic data release, every U.S. Treasury auction result, every oil price fluctuation, and even every speech by Federal Reserve officials could have a greater impact on the yield curve and overall market sentiment. This bears some resemblance to the market dynamics during the “taper tantrum” in early 2013—when a lack of trust led to a substantial tightening of financial conditions, even though the policy itself did not change until later that year.

Small Caps and Tech Stocks Bear the Brunt

The high interest rate volatility environment poses a direct threat to duration-sensitive assets. Small-cap stocks, which have a higher refinancing demand, are particularly vulnerable in times of rising interest rate uncertainty; the tech sector also faces pressure, as large-scale cloud computing companies increasingly rely on long-term debt for capital expenditures, and sustained fluctuations in long-term rates will directly raise their financing costs.

Long-term bonds also face additional pressure from the supply side: the scale of sovereign debt issuance is expanding, the supply of corporate bonds from tech companies is increasing, while the Federal Reserve's demand for government bonds is decreasing in the context of balance sheet reduction. The short end faces another type of tail risk—if the Federal Reserve delays action, it may ultimately have to raise rates more significantly to restore credibility, which increases the importance of upcoming economic data.

Dual Pressure from Inflation Resilience and Growth Continuity

The current high-volatility environment is not isolated but has deep macroeconomic foundations. Global inflation is becoming more persistent, with ongoing fiscal expansion, energy supply insecurity, and capital-intensive fixed investments driven by AI infrastructure collectively providing structural support for inflation.

The U.S. economy also shows strong resilience. The growth rate of real final demand in the second quarter exceeded expectations, supported by the wealth effect, loose fiscal policy, and rigid demand for AI-related investments. The Federal Reserve's policy focus has shifted from balancing dual mandates to prioritizing inflation; if growth accelerates further or the labor market remains strong, this tendency will be further reinforced.

Energy prices are the most direct transmission channel. Rising oil prices will elevate inflation expectations, widen the market's expectations for the policy path, thereby increasing interest rate volatility and pushing real yields upward along the curve. This high-volatility pattern is expected to persist until Waller provides a clearer explanation of his policy framework.
