Will the United States and Iran reach a formal nuclear agreement by the end of Q4 2026?
What moved
U.S.-Iran hostilities revived energy and inflation risks; bond yields surged across major markets with Japan and U.K. yields at multi-decade highs.
The market transmission
The channel is energy cost into inflation expectations. Rising yields reflect repricing of long-duration real returns against higher expected inflation from disrupted energy supplies. The move is broad across rate markets and not confined to one region, suggesting the market is pricing a sustained elevation in oil and gas costs and the inflation pass-through that follows.
What would change this
Multi-decade yield highs are notable, but the signal does not state the absolute levels or the day's move in basis points, so the magnitude of repricing cannot be calibrated. The move is consistent with a shift in inflation risk premium rather than a shift in growth expectations. Whether this repricing holds depends on whether the hostilities actually disrupt crude flows or whether markets retreat from the inflation signal once the near-term risk recedes.
