Trump rules out Iran strikes before midterms, oil falls; NY Fed pins tariff inflation; bond markets ease

Donald Trump has taken a military option off the table before November's midterms, and oil markets moved immediately. Separately, researchers at the New York Federal Reserve have put a number on what tariffs actually cost American consumers, and it is bigger than most estimates. European bond yields are falling, giving markets a rare morning of relief after weeks of turbulence.

Trump rules out Iran strikes before midterms; Brent crude falls as war premium unwinds

Hormuz Oil Risk 2026EnergyConflictElections

President Trump said he will not attack Iran before the November midterm elections, removing the near-term military risk that had kept an extra premium in oil prices. Brent crude fell on the news. China also restarted fuel exports this week, adding to the supply-side relief. The USS Abraham Lincoln has returned to San Diego after a record uninterrupted deployment supporting the Iran campaign.

Why it matters

Oil prices carry a war premium, the extra price buyers pay because a conflict might disrupt supply. When that risk shrinks, the premium unwinds and prices fall. Lower Brent matters for inflation across every oil-importing economy: cheaper crude feeds through to petrol, transport and manufacturing costs within weeks. For the US midterms, gas prices above $4 a gallon are a political liability, so Trump's statement is also an economic signal to voters. China restarting fuel exports adds real supply to the market, reinforcing the price drop through a separate channel.

IB perspective

The price of oil is not just the cost of pumping it out of the ground. It includes a risk premium, the extra amount traders pay because something bad might happen to supply. When Trump appeared to rule out strikes on Iran before November, that specific risk shrank, and the premium unwound fast. This is the market doing what markets do: pricing in new information the moment it arrives. The mechanism is straightforward. Traders had priced in a chance of a strike disrupting Strait of Hormuz flows. That probability fell. So the expected future price of oil fell. Spot prices followed.

The precedent that comes to mind is the brief de-escalation in the Gulf in late 2019, when a similar verbal signal from Washington knocked several dollars off Brent within hours, only for prices to recover when the signal proved ambiguous. That parallel is useful but limited: in 2019 the underlying supply picture was looser, and OPEC had more spare capacity to absorb a shock. Today, with Brent having held above $101 for weeks and OPEC+ already running near its agreed ceiling, the market has less of a buffer. If Trump's statement is reversed after November, the premium could return faster than it left.

NY Fed: tariffs added 2.9 percentage points to US inflation across 67 goods categories

Global Bond Sell-Off 2026TradeElectionsCentral banks

Researchers at the Federal Reserve Bank of New York found that Trump's tariffs added 2.9 percentage points to inflation across 67 categories of consumer goods by February 2026. The finding suggests that importers passed almost the entire cost of the tariffs on to American shoppers rather than absorbing them in their own margins. Gas prices are separately expected to stay above $4 a gallon through Election Day, according to prediction-market traders.

Why it matters

This is the clearest official estimate yet of what tariffs cost ordinary Americans. A 2.9 percentage-point addition to inflation in affected categories is not a rounding error: it is the difference between inflation that feels manageable and inflation that changes how people vote. The finding also complicates the Fed's job. If a significant share of current inflation is tariff-driven rather than demand-driven, raising interest rates, which works by slowing spending, is a blunt tool for the wrong cause. That tension sits at the heart of every Fed decision between now and the midterms.

IB perspective

The NY Fed result is a near-perfect illustration of pass-through, the share of a cost increase that ends up in the final price paid by the consumer. A tariff is a tax on imports. The government collects it from the importer. The question is always who really pays: the importer, who absorbs it in lower profit, or the buyer, who pays a higher price. The NY Fed's finding of 2.9 percentage points across 67 categories suggests pass-through was close to complete in those goods. Importers did not absorb the cost. They passed it on.

What makes this politically and economically awkward is the timing. The Fed has been raising rates to bring inflation down, on the assumption that inflation is being driven by too much spending chasing too few goods. But if a large chunk of inflation is coming from tariffs, higher interest rates do not fix it. Rates slow borrowing and spending. They do not reduce the tax on imports. The Fed is, in effect, asking households to spend less in order to offset a price rise the government created. One month of data is not proof of a permanent shift, and the February 2026 figure may not capture how retailers have adjusted since. But the direction of the finding is hard to argue with.

European bond yields ease as ECB repo funding comes into focus amid market turbulence

Global Bond Sell-Off 2026Central banksMarkets

European bond markets steadied on Friday, with yields falling and equity markets opening higher. The European Central Bank's repo facility, a tool that lets banks borrow short-term cash against collateral, is drawing attention as a potential backstop during the recent turbulence. ECB minutes from its last meeting are also due, giving markets a read on how policymakers are thinking about the bond stress.

Why it matters

When government bond yields rise sharply, the cost of borrowing for every government in the eurozone goes up, and banks that hold those bonds as safe assets see the value of their balance sheets fall. The ECB's repo facility, where it lends cash to banks in exchange for bonds as security, is one of the tools that can prevent a liquidity squeeze, a situation where banks cannot easily turn assets into cash, from becoming a solvency crisis. Friday's easing is a one-day move, not a trend reversal, but it matters because it reduces the immediate pressure on France and other high-debt eurozone members.

IB perspective

A government bond yield is the annual return a buyer gets for lending money to a government. When investors sell bonds, the price falls and the yield rises, because the fixed interest payment is now a bigger share of the lower price. The ECB's repo facility works as a circuit-breaker: if banks are struggling to fund themselves because bond prices are falling, the ECB lends them cash and takes the bonds as temporary security. This keeps the banking system liquid, meaning banks can still meet their short-term obligations, even when the bond market is volatile. The facility does not stop yields from rising, but it stops a yield spike from becoming a bank funding crisis.

The debate worth watching is whether the ECB can keep using these tools while also raising rates to fight inflation. Raising rates pushes bond yields up, which is exactly the stress the repo facility is meant to cushion. The two policies pull in opposite directions. The ECB faced a version of this in 2022, when it launched its Transmission Protection Instrument to buy bonds in stressed markets while simultaneously hiking rates. That episode is the closest precedent, and it held, but only because the ECB acted quickly and credibly. Whether the same credibility holds today, with French debt at a new high and political uncertainty in several member states, is the question the minutes may not fully answer.

Concept of the day

Pass-through

Pass-through is the share of a cost increase that a seller passes on to the buyer as a higher price. If a tariff raises the cost of importing a good by 10% and the shop price rises by 10%, pass-through is complete. If the price rises by only 5%, pass-through is partial, because the seller absorbed the rest.

In practiceIn Story 2, the NY Fed found that tariffs added 2.9 percentage points to inflation across 67 categories of goods by February 2026, suggesting near-complete pass-through in those sectors: importers passed almost the entire tariff cost straight to American shoppers.
