Trump tariffs, oil spike strain markets
- Treasury’s borrowing advisers said on May 5 that oil prices have dominated markets, surging nearly 60% since the Iran conflict began and 80% in 2026. - Mark Zandi of Moody’s Analytics said a year of Trump tariffs has caused “significant damage,” with inflation near 3% and job growth stalling. - Together, pricier energy and weaker trade flows leave the Fed and Treasury facing uglier inflation, borrowing, and growth tradeoffs.
Markets are getting squeezed from two sides at once. Oil has ripped higher after the Iran conflict, and Trump’s tariff program is now showing up in the real economy instead of just in trade-policy arguments. That matters because one shock pushes up energy and shipping costs, while the other raises import prices and scrambles supply chains. Put them together and the usual policy playbook starts to look cramped. ### What changed this week? The cleanest official signal came from the Treasury Borrowing Advisory Committee on May 5. The group told Treasury that financial markets have been “highly influenced” by oil, with prices up nearly 60% since the Iran conflict started and nearly 80% since the start of 2026. It also said the broader commodity index has moved above its pandemic-era 2022 high. (home.treasury.gov) ### Why does an oil spike hit everything so fast? Oil is not just a gas-station story. It feeds freight, aviation, petrochemicals, plastics, fertilizer, and a lot of industrial input costs. So when crude jumps this hard, the first hit lands in energy bills, but the second hit spreads through transport and goods prices. That is why Treasury’s advisers flagged global rates(home.treasury.gov)ank expectations. (home.treasury.gov) ### Where do tariffs come in? Tariffs work like a tax on imports, but the pain does not stay at the border. U.S. companies either absorb the cost in margins, pass it through to customers, or rework supply chains in a hurry — usually some mix of all three. Mark Zandi at Moody’s Analytics argued this week that the data now show “significant damage” from Trump’s tariff prog(home.treasury.gov)riff push. (independent.co.uk) ### What damage is Moody’s pointing to? The two big buckets are inflation and hiring. Zandi said inflation has been running around 3% year over year — still above the Fed’s target — while job growth outside healthcare has effectively stalled. That is the ugly version of a tariff shock: prices stay sticky, but growth does not stay strong enough to justify them. (msn.com) ### Why is this especially bad for bonds? Treasury has to finance the government no matter what markets are doing. But higher inflation pressure usually means investors demand higher yields, and higher yields make federal borrowing more expensive. The May TBAC minutes also pointed to a projected $1.3 trillion funding shortfall in (msn.com)ney into a market already nervous about inflation. (home.treasury.gov) ### Doesn’t one shock cancel the other? Not really. If tariffs were crushing demand on their own, they might cool some price pressures over time. If oil were the only problem, policymakers could hope it fades with geopolitics. But together they create the worst mix — weaker growth potential alongside higher headline inflation. That is the kind of setup that makes the Fed(home.treasury.gov)# So what are markets actually watching now? Three things. First, whether oil stays elevated or keeps climbing. Second, whether tariff-related price increases broaden beyond the most exposed import categories. Third, whether Treasury has to lean harder on issuance just as buyers demand more compensation for inflation risk. Those are all live questions now, not distant hypotheticals. (home.treasury.gov) ### Bottom line This is no longer a story about abstract policy disruption. It is a story about two real price shocks hitting the same economy at the same time — and leaving much less room for easy fixes.
