Siebert Financial stated that the breakthrough of the US 10-year government bond yield above 5% fundamentally changes portfolio calculations, as investors no longer need to take high risks to achieve substantial nominal returns. Mark Malek, its Chief Information Officer, believes that the biggest market risk currently is complacency, not catastrophe, and high bond yields are both a warning and an opportunity. The US 10-year government bond yield touched 5.310% overnight, a new high since May 2002, and is currently at 5.278%. Ipek Ozkardeskaya, Senior Analyst at Swissquote, pointed out that rising long-term bond yields intensify capital competition, leading some investors to shift towards safer US Treasuries.
