# Bond yield surge and Iran conflict stoke inflation fears

Yields hit multiyear highs: The 30-year Treasury topped 5% and the 10-year surpassed 4.5%, raising borrowing costs and pressuring equity valuations. Geopolitical inflation risks: The Iran conflict has driven oil above $100, with fears that a prolonged Strait of Hormuz closure could embed inflation into the global economy. Earnings keep stocks afloat: First-quarter U.S. corporate profits are on track to rise 28% year-over-year, offsetting some market worries despite elevated valuations.
