Treasury: oil up nearly 80%
- The Treasury’s debt advisory committee told Treasury Secretary Scott Bessent this week that oil has surged nearly 80% in 2026 and 60% since the Iran conflict began. - The warning sat inside the May 6 quarterly refunding report, which said commodities are now above their 2022 pandemic-era peak and pressuring global rates. - That matters because sticky energy inflation makes Fed cuts harder — and keeps mortgages and other borrowing costs higher.
Oil is suddenly back at the center of the inflation story. Not because a bank economist floated a scenario, but because the Treasury Borrowing Advisory Committee put the warning straight into its formal report to Treasury this week. The committee said oil prices are up nearly 60% since the Iran conflict began and nearly 80% since the start of 2026. It also said the broader commodity index has climbed above its 2022 pandemic-era high. (home.treasury.gov) ### What is this committee, exactly? The Treasury Borrowing Advisory Committee — usually shortened to TBAC — is the group that advises Treasury on how to finance the government. Most of the time, that means bond issuance, auction sizes, and investor demand. But its quarterly reports also sketch the market backdrop Treasury is borrowing into. So when TBAC flags oil and commodities this blun(home.treasury.gov)y prices are already pushing through the rates market Treasury depends on. (home.treasury.gov) ### Why does oil show up in a Treasury report? Because oil is one of the fastest ways a geopolitical shock turns into an inflation problem. Higher crude lifts gasoline, diesel, jet fuel, shipping, plastics, fertilizer, and a lot of industrial inputs. That does not hit every price tag at once, but it changes the inflation mood fast — and bond markets react before the full pass-through shows(home.treasury.gov)felt “most acutely” in global rates markets.

A conflict tied to the Gulf raises fears around production, transport routes, and sanctions spillovers. You can think of it like an insurance premium suddenly getting stapled onto every barrel. Even if physical supply has not fully disappeared, the market sta(home.treasury.gov)link explicit by measuring the oil jump from the start of the Iran conflict. (home.treasury.gov) ### What changed this week? The new thing is the venue and the wording. This was not a TV hit or a market note. It was the committee’s May 6 report to Treasury, released alongside the quarterly refunding documents. That gives the warning extra weight because it ties the oil move directly to financing conditions, inflation pressure, and interest-rate sensitivity at the same moment Treasury is managing huge borrowing needs. (home.treasury.gov) ### So what does this mean for the Fed? Basically, an oil spike makes the Fed’s job uglier. Central bankers can usually look through one-off energy moves if the shock fades quickly. But when oil drags broader commodities higher and starts lifting inflation expectations, the case for cutting rates gets weaker. That is why an energy shock can keep policy tighter even if growth is slowing. Th(home.treasury.gov) inflation fallout. TBAC’s report is a reminder that this risk is live, not theoretical. (home.treasury.gov) ### Why are mortgages part of this story? Mortgage rates do not move one-for-one with the Fed’s policy rate, but they are heavily shaped by inflation expectations and Treasury yields. If markets think oil will keep inflation hotter for longer, longer-term yields can stay elevated. CBS’s May 7 mortgage roundup put the average 30-year refinance rate at 6.43%, which is exactly the kind of borrowing-cost backdrop that gets harder to improve when energy shocks hit.

Fertilizer and transport matter for food. Manufacturing inputs matter for goods prices. One oil shock can spread through the economy in layers, which is why bond markets tend to care before consumers can name every channel. (home.treasury.gov) ### Bottom line The real news is not just that oil is up. It is that Treasury’s own market advisers are treating the jump as a live inflation and rates problem right now — one big enough to complicate Fed cuts, Treasury borrowing, and everyday financing costs all at once.
