The U.S. 30-year Treasury yield climbed above 5.61% on Tuesday, reaching its highest level since 2002, before easing to 5.466%. The 10-year Treasury yield also declined slightly to 5.2278% after rising the previous session.
Energy price pressures linked to the ongoing U.S.-Iran conflict have contributed to expectations of further Federal Reserve interest-rate increases. Markets were pricing in more than a 72% probability of an October rate hike, according to the supplied report.
The $32 trillion Treasury market has declined 2.6% this year, compared with a 6.3% gain last year.
State Street Investment Management strategist Masahiko Loo said October could present another test for Treasuries as bond issuance increases and competition for capital intensifies.
