Making Sense of Yields

Short thoughts and portfolio takeaways.

All the focus is on yields.

Implied yields on G7 government debt with maturities beyond 10 years had climbed above 4.6% for the first time since 2004. The US 30-year Treasury is around 5.17%, the UK 30-year gilt touched 5.82%, and the Bank of Japan is being forced to consider whether market instability might require a slower pace of balance-sheet run-off.

Each country may have individual reasons adding to its bond selloff, but the selloff itself is global.

There is one main story driving this higher, a noisy one of war, oil, and inflation expectations. Markets now have the Fed on hold through 2026, and have shifted far enough to price a possible hike by January. Beneath that headline story, there are a few dynamics we think deserve more attention.

  • The first is that hyperscalers are funding an AI buildout of extraordinary scale, and have increasingly leaned on debt markets to do it.

  • The second is that a continued shift higher in rates changes the equity leadership map, making financials and banks a more natural home for risk than the most duration-sensitive parts of the market.

  • The third is that the UK has its own idiosyncratic fiscal and political vulnerabilities, which give long-end gilts a higher beta to the global duration selloff than US Treasuries or most other G10 markets.

Not all rising yields are equal. A move driven by collapsing credit quality is one thing. A move driven by stronger nominal growth, higher real rates, and a fatter term premium is another.
