Stocks tumble, bond yields jump as Iran war fuels central bank reassessment - Reuters

Global equities fell while government bond yields rose as investors reassessed the outlook for central bank policy amid the conflict involving Iran, according to Reuters. The moves suggest markets are repricing the balance between inflation risk and growth risk rather than reacting to a single headline.

Higher bond yields matter because they feed directly into the discount rates used to value stocks, pressuring longer-duration and rate-sensitive sectors most. At the same time, an energy-driven supply shock can complicate the picture for central banks: it may push up near-term inflation even as it weighs on activity, leaving policymakers with less room to cut rates quickly.

For observers, the key question is whether the shift proves temporary or durable. Watch energy prices, official commentary on inflation expectations, and upcoming policy meetings. If markets conclude that central banks must stay restrictive for longer, rate-sensitive assets could remain under pressure; if the shock fades, some of the move may reverse.
