U.S. 30-Year Treasury Yields Surge to 5.32%, Highest Since 2007
The 30-year Treasury yield rose to 5.32% at 3:15 a.m. on Aug. 18, matching levels last seen in June 2007 before the 2008 financial crisis. Investors view the spike as a signal of lingering macro‑economic stress.

July’s jobs report showed a surprise loss of 23,000 jobs, far below the 80,000 gain economists expected, while inflation slipped to 3.4% year‑over‑year, still well above the 2.4% rate before the war. These weak data points add to the pressure on Treasury yields.

The five largest U.S. hyperscalers have already issued $159 billion in bonds by mid‑2026, eclipsing the full‑year 2025 total of $121 billion as they fund AI infrastructure. The surge in corporate borrowing adds further upward pressure on yields.
The 10-year yield climbed from 4.36% on June 30 to 4.74% on Aug. 18, keeping long‑term rates under pressure. Higher 10‑year yields reinforce the narrative of rising financing costs across the economy.
ING Bank strategists said yields are “returning to more sensible levels,” pointing to pre‑2008 benchmarks as a reference point. They argue the current trajectory is a gradual reversion to normal rates rather than a sudden shock.
