Long‑Dated Yields Hit Multi‑Decade Highs as Oil Risk Keeps Markets on Edge

Persistent oil risk from the U.S.–Iran war, fuelled by rising demand for AI capital, is tightening global financing conditions and raising borrowing costs worldwide.

Overview

  • The global bond sell‑off pushed U.S. 10‑year and 30‑year Treasury yields to levels not seen since the early 2000s, with long yields briefly touching multi‑decade highs on Oct. 1.
  • Oil prices have stayed elevated because of the seven‑month U.S.–Iran conflict and stalled talks over the Strait of Hormuz, which has amplified inflation fears and helped keep yields high.
  • A softer August PCE inflation reading of 3.4% reduced the odds of an immediate Fed hike but did not arrest the rise in long yields, leaving monetary policy direction uncertain ahead of U.S. jobs data.
  • Equities are split as AI and chip names rally on strong orders and Micron’s upbeat guidance while rate‑sensitive sectors and emerging‑market stocks face pressure from higher U.S. yields.
  • Higher borrowing costs are squeezing emerging markets: India has seen large foreign portfolio outflows and Pakistan has introduced a Strategic Action Plan to deepen its local currency bond market and cut external risks.
