United Kingdom Daily Briefing

The US Treasury auctioned 30-year paper at the highest borrowing cost since 2001, per the Financial Times, driven by concerns about US fiscal sustainability and persistently elevated inflation. For gilt investors, this matters directly: UK long-end yields are anchored partly by US Treasury levels, and a sustained move higher in US 30-year yields will apply upward pressure on gilts, squeezing the BoE's rate-cut timing. The BoE has less fiscal room than the US to absorb yield curve steepening.

The Financial Times reported that FBI investigators seized the phone of a Guggenheim Partners executive as part of a broader probe into billionaire Mark Walter's business empire, extending US scrutiny beyond insurance holdings into securities and asset management.
