Global Bond Rout: US 30-Year Yield Hits 2007 High as Inflation Fears Spike

The equity rally that had powered the S&P 500 to new all-time highs over the past six weeks collided with a wall of bond selling on Friday, as inflationThe rate at which prices rise across an economy. fears stemming from Iran-driven oil supply disruptions forced a reckoning on real yields across all maturities. The 30-year US Treasury yield climbed to levels last seen before the 2008 financial crisis, a move that caught many traders off guard given the persistent narrative that the Fed would remain accommodative through 2026. The selloff was truly global: yields surged from Japan to Germany to the UK, with G7 finance chiefs preparing to discuss the bond rout in emergency sessions.

The Producer Price Index hit 6%, reigniting fears that central banks would need to tighten policy just as the market was pricing in a 'Fed pivot' or at minimum a patient, data-dependent stance. Wall Street pricing in the futures market now reflects a non-trivial probability of a Fed rate hike as soon as December 2026, a jarring reversal from the rate-cut hopes that dominated sentiment in April.

The cross-asset implications are severe: stocks sold off sharply into the close as higher real rates directly reduce the net present value of future corporate earnings.

Energy stocks, paradoxically, also retreated despite higher oil prices, as the energy sector's leverage and duration-sensitive debt burdens meant higher yields were net negative.

The debate now centers on whether this is a temporary, oil-shock-driven correction or the start of a structural re-rating in the cost of capital. Sceptics point to the Iran war context: once Iran is no longer able to disrupt Hormuz traffic, oil prices may normalize and inflationThe rate at which prices rise across an economy. may moderate. Believers in the bond selloff argue that the US has entered a new regime of elevated real yields, driven by fiscal deficits, energy scarcity, and the end of quantitative easing; in that world, equities are less attractive and re-rating lower is inevitable. The outcome of next week's Fed communications and any additional oil-supply shocks will likely be decisive.
