Contrary to central bank theories, falling term premia do not reflect low inflation expectations. Instead, they signal investors' rising demand for safe-haven government bonds as liquidity tightens and systemic risks grow. It is a risk-off signal, not a risk-on one.

For over a decade, Fed forward guidance and QE have suppressed interest rate volatility. A shift away from this communication strategy would likely cause volatility to return to the more "normal," higher levels seen before the 2008 global financial crisis.

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.

Bonds are caught between inflationary pressures (negative) and growth risks (positive). This tension is viewed as unsustainable and likely to resolve with yields falling, as either inflation abates or a prolonged disruption forces a focus on severe growth risks.

Kevin Warsh advocates for the Dallas Trimmed Mean inflation metric, which excludes extreme price moves. However, this gauge can be misleading. A single significant shock, like oil prices, initially gets excluded but its effects gradually bleed into many other items, causing the metric to lag behind true underlying inflation.

While investors often watch equity markets for signs of Fed intervention, rising bond volatility poses a more significant risk to financial conditions. This makes the Fed more sensitive to instability in the bond market, meaning a spike there could trigger a dovish policy shift sooner than a stock market downturn.

The bond market will become volatile not when rates hit a certain number, but when the market perceives the Fed's cutting cycle has ended and the next move could be a hike. This "legitimate pause" will cause a rapid, painful steepening of the yield curve.

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.

While equities had a mixed reaction to inflation data, the bond market shows clearer concern. FedWatch data reveals a significant shift in expectations over the past month, with the probability of a 25 basis point rate hike by year-end rising to 30%, while the probability of a cut has diminished.
