Despite market speculation about potential cuts to long-end Treasury auction sizes, the primary dealer agenda for the next refunding shows no such intention. The Treasury's focus on other topics suggests it will likely maintain or even increase coupon auction sizes next year, pointing to continued supply pressure.

Contrary to fears of a spike, a major rise in 10-year Treasury yields is unlikely. The current wide gap between long-term yields and the Fed's lower policy rate—a multi-year anomaly—makes these bonds increasingly attractive to buyers. This dynamic creates a natural ceiling on how high long-term rates can go.

Uncertainty around the 2026 Fed Chair nomination is influencing markets now. The perceived higher likelihood of dovish candidates keeps long-term policy expectations soft, putting upward pressure on the yield curve's slope independent of immediate economic data.

UK Sterling weakened despite news that personal income tax hikes might be avoided in the upcoming budget. This counterintuitive reaction, paired with rising Gilt yields, signals that investors are more concerned about the government's fiscal discipline and policy uncertainty than they are optimistic about potential short-term stimulus.

Sterling's reaction to potential UK budget options is "any news is bad news." Even less-damaging proposals cause weakness because the market understands any policy will result in fiscal tightening, forcing the Bank of England to react dovishly.

The Fed is prioritizing its labor market mandate over its inflation target. This "asymmetrically dovish" policy is expected to lead to stronger growth and higher inflation, biasing inflation expectations and long-end yields upward, causing the yield curve to steepen.

A surprisingly hawkish BOJ tone, with dissents for a rate hike, bolstered its policy normalization credibility. This stemmed bearish sentiment at the long end of the JGB curve, shifting rate hike pressure to the front end and creating a bias for the curve to flatten.

The recent widening of long-end swap spreads was driven by expectations for a benchmark rate change and an earlier end to QT. The FOMC meeting disappointed on both fronts, causing spreads to narrow as the specific catalysts priced by the market failed to materialize. This highlights how granular policy expectations drive specific market instruments.

The recent flattening of Japan's yield curve masks underlying structural weakness in the superlong-end bond market. Reduced purchases by the Bank of Japan will keep net supply high, creating a challenging supply-demand dynamic that domestic investors alone may struggle to absorb, even if the Ministry of Finance cuts issuance.
