The Globe and Mail reports in its Wednesday, May 20, edition that the recent sharp sell-off in U.S. Treasuries may continue due to persistent inflation, changing interest rate expectations and shifts in investor behaviour, which could further pressure bond prices and increase yields in the coming weeks. A Reuters dispatch to The Globe reports that on Tuesday, the benchmark 10-year yield climbed to its highest level since January last year and was last at 4.67 per cent. U.S. 30-year yields, on the other hand, jumped to a level not seen since June, 2007, and last changed hands at 5.17 per cent. For months, investors saw the 4.5-per-cent yield on the 10-year note as a good entry point for bonds. However, as yields rose beyond that level, their expectations for buyer interest shifted. AmeriVet Securities' Gregory Faranello says: "This kind of feels like the COVID era, but we weren't raising rates through COVID, we were lowering rates. So it's very tricky and there are definitely some technical things coming into play." ING's Padhraic Garvey believes that the 10-year yield is headed to 4.75 per cent. Rising benchmark yields pose a challenge for U.S. stocks, as higher borrowing costs weigh on companies and consumers.
