Oil prices just did something that months of Federal Reserve jawboning couldn’t: they gave bond investors a reason to buy again.
Treasuries climbed as crude oil’s sharp decline reshaped the inflation picture in the US, with the 30-year Treasury yield retreating from a mid-May peak of 5.18% to around 5.00%. That 18-basis-point move might not sound dramatic, but in a market where every tick represents billions of dollars in portfolio value, it’s the kind of shift that gets attention.
The oil price collapse behind the rally
Brent crude fell nearly 20% over the course of May, sliding from above $118 per barrel in late April to roughly $92.05 by month’s end. The catalyst was growing optimism around a potential US-Iran ceasefire, even as tensions in the Strait of Hormuz, one of the world’s most critical oil chokepoints, continued to simmer.
When oil drops, input costs fall across the economy, reducing upward pressure on the Consumer Price Index. Economists call this the “energy pass-through effect,” and it’s one of the most reliable transmission mechanisms from commodity markets to consumer prices.
