YIELDS on government securities (GS) closed mostly lower last week as volatile oil prices and a hawkish US Federal Reserve pause kept the market defensive. Meanwhile, the 182-day tenor rose by 4.47 bps week on week to yield 5.5261%. At the long end, the 10-year bond’s yield slid by 17.51 bps week on week to 7.4299%. On Friday, longer-dated Treasury yields pushed to new multi-year highs after several Federal Reserve officials argued that further interest rate hikes are needed to combat inflation, Reuters reported. The 30-year bond yield rose 5.14 basis points to 5.2584%, the highest since mid-2007.
