Historic yield spike: The 30-year Treasury yield hit 5.18%, its highest since 2007, as inflation and fiscal worries fueled a bond market selloff. Fiscal costs rising: Higher yields could add $2 trillion to U.S. debt over the next decade, with interest payments consuming 30% of federal revenue by 2036. Equities under pressure: Stocks remain near records, but analysts warn yields near 5% on 10-year Treasuries could weigh on valuations and borrowing costs.
