Investors start the week with markets jittery, as the ongoing Iran war injects fresh uncertainty into asset prices. Bond yields have climbed, pushing global interest rates higher and reminding traders that geopolitical flare‑ups can quickly reshape financing conditions. Equities across Europe and Asia slipped as risk appetite waned.

Rising yields have revived concerns that inflation could persist longer than central banks anticipate. Treasury traders note that the spread between 10‑year notes and inflation‑linked bonds has widened, a classic signal that markets price in higher price growth. That backdrop pressures corporate borrowers, whose debt servicing costs climb alongside the benchmark rates.

Equity sectors most exposed to financing costs—such as real estate, utilities and high‑yield issuers—registered the steepest declines on regional screens. Meanwhile, defensive staples and technology names held steadier ground, benefitting from investors' shift toward cash‑generating businesses. The bond market’s move has therefore reshaped the day’s sector rotation.

With no clear end in sight to the conflict, market participants will monitor bond spreads for clues about future rate paths. Any further tightening could tighten corporate balance sheets and test valuation multiples. For now, the heightened inflation alarm keeps risk‑off sentiment firmly in place.
