U.S. Treasury yields have risen significantly as global bond markets react to concerns about inflation. The yield on the 10-year U.S. Treasury note increased by over 2 basis points to 4.6173%, marking its highest level in 15 months. The 30-year Treasury bond yield also reached a two-decade high at 5.1418%, following a 1 basis point increase. The 2-year Treasury note yield rose to 4.1008%.

This surge in yields follows a notable increase last week, where the 10-year yield rose by 14 basis points, driven by rising consumer prices and import costs under the new Federal Reserve chair, Kevin Warsh. The increase in U.S. borrowing costs has had a ripple effect on global markets, with German bund yields rising to 3.1827% and Japan's 10-year JGB climbing to 2.739%.

In the U.K., 10-year Gilt yields eased slightly but remain high at 5.169%, amid political uncertainty regarding Prime Minister Keir Starmer. Will Hobbs, chief investment officer at Brooks Macdonald, highlighted the challenges central banks face with inflation, calling it a "tricky, annoying problem". Additionally, oil prices have surged, with Brent crude rising 1.8% to $111.16 per barrel and U.S.

West Texas Intermediate futures increasing over 2% to $107.56 per barrel. Lizzie Galbraith, a senior political economist at Aberdeen, noted that the energy price shock and ongoing political turmoil in the U.K. could lead to increased risk premiums on U.K. gilts
