Asian markets tumble as US-Iran fighting lifts oil and bond yields - Reuters

Asian markets opened sharply lower as escalating military action between the United States and Iran rattled investor confidence. The immediate reaction was a flight from risk-sensitive equities, while oil prices climbed on concerns about supply disruption in the Middle East. At the same time, bond yields moved higher, signaling that markets were beginning to price in the potential inflationary impact of elevated energy costs rather than purely seeking safe-haven assets.

The move underscores how geopolitical shocks can create unusual cross-asset signals. Rising oil typically feeds into inflation expectations, which pushes long-term bond yields upward even as equities fall. For investors, that means the conflict is not just a risk-off event, but also a test of how central banks and markets balance growth concerns against price pressures. The direction of yields may be as important as the headline tension in gauging the broader economic mood.

Attention should remain on diplomatic developments and any further escalation, as well as the trajectory of crude prices. If energy costs stay elevated, bond yields could continue to reflect shifting rate outlooks, while equity volatility may persist until clarity emerges. How long these moves last depends on whether the conflict remains contained or expands further.
