Archived — this story has rotated out of today’s deck. It is kept here in full.

The gist

US 30-year Treasury auction yield hit 5.216%, highest since 2001. Rising borrowing costs signal market demands higher compensation for deficits and inflation.

Background

Government borrowing costs have surged as investors demand higher yields to hold long-term debt, driven by persistent inflation, large budget deficits, and heavy Treasury issuance. The US national debt is nearing $40 trillion, and the July budget deficit hit a record $432 billion. Similar trends are seen in Japan and the UK, where borrowing costs have also reached multi-year highs.
