The 10-year hits 5%. Why now?
Three-way yield decomposition
On 19 October, the benchmark ten-year US Treasury yield touched 4.99 per cent, bringing the totemic 5.0 per cent threshold into direct sight for the first time since July 2007. The suddenness and velocity of the move have stunned market participants who spent a decade conditioned to zero-interest-rate environments. Decomposing the yield advance exposes the true engine behind the sovereign rout.
The Three-Way Decomposition
Quantitative analysis shows that expected inflation has remained anchored near 2.3 per cent, while short-term policy rate expectations have actually cooled. The entire surge in ten-year yields has been driven by a violent expansion in the term premium and soaring real yields. Investors are demanding unprecedented compensation for duration risk, fiscal recklessness, and the quantitative tightening unwind of central bank balance sheets.
The ten-year Treasury yield did not reach five per cent because of inflation panic, but because the market has finally assigned a punitive price to sovereign fiscal profligacy and duration risk.
