Ten-year Treasury yield climbs to 5.30%, its highest since 2002, despite cooler inflation

A softer inflation reading normally pulls the 10-year yield down, because most of a long yield is the market's forecast of where short rates will sit over the next decade. On Wednesday the reading softened and the yield rose anyway ^[1][3]. Neither report splits the 5.30% into that forecast and the term premium, the extra yield buyers demand for holding long debt, so the cause has to be inferred from what else moved that week.

Growth is one candidate. Stronger activity lifts the rate path the market expects, and the US data that day ran hot, according to Seeking Alpha ^[5]. Debt is the other. Semafor framed the global rout around mounting government borrowing as well as inflation ^[4], and more supply raises the premium buyers ask. The 30-year Treasury made its move first this week ^[2]. The longest bond is usually the one most sensitive to supply.

France is the one concrete piece of new supply in either account. It announced record bond sales this week while its debt-to-GDP ratio rises, and Semafor expects its draft budget to be politically divisive ^[7][8]. By scheduling record issuance into a selloff, the French treasury has chosen to fund its deficit now at whatever yield the market sets ^[7].

For valuation, the useful number is the yield turned upside down. A 10-year note at 5.30% pays $53 a year on $1,000 ^[11]. Paying $1,000 for $53 of income is a multiple of about 18.9 times ^[10]. A company valued above 18.9 times earnings now earns less on today's profit than the Treasury pays in coupon, and its buyer is paying for growth that has yet to show up.

If growth is driving yields, the higher discount rate comes with higher revenue, and part of the valuation loss is offset ^[5]. A debt-supply driver raises the discount rate with no matching rise in cash flow, and the whole loss lands. And if Europe is the driver through French fiscal politics ^[8], the move can reverse once Paris publishes a budget buyers accept. I think supply has the better support in these two reports, because the longest bond moved first ^[2] and France's record issuance arrived the same week ^[7]. The counter-case is plain. Hot US growth on the day the 10-year hit its high is the most direct explanation ^[5]. Semafor itself describes Asian bonds falling because US yields rose ^[9], so the global spread need not mean a global debt problem.
