Welcome back to the Trading Partner Inflation Check. Every month, we track the latest consumer price data from America’s nine largest trading partners. The goal is simple: inflation doesn’t stop at the border. What’s happening in Mexico City, Tokyo, or New Delhi flows right back into U.S. supply chains, input costs, and — eventually — your wallet.
Here’s where things stood as of June 2026.
The headline: America’s inflation problem is getting worse
The United States clocked in at 4.2% in May — the highest reading since April 2023 and the third consecutive monthly acceleration. Energy costs are driving the bus: gasoline prices soared 40.5% year-over-year, fuel oil jumped 58.9%. The Iran conflict’s energy shock isn’t fading — it’s compounding. Core inflation, which strips out food and energy, hit 2.9%, the highest since September 2025. That tells you the underlying trend isn’t just an energy story.
The average inflation rate across the nine major trading partners sits at 2.9% — lower than the U.S. headline, but the direction of travel matters more than the absolute level right now. Five of nine countries saw their rates tick higher. Two held steady. Only two — Mexico and Germany — posted genuine disinflation.
The winners: Mexico and Germany ease off the gas
Mexico dropped to 3.94% from 4.45%, sliding back inside Banxico’s tolerance band for the first time in months. The secret? Aggressive government fuel tax credits and price caps that kept energy inflation at just 3.27% — remarkably restrained given what’s happening in global oil markets. Food inflation also cooled from 6.36% to 5.13%. Mexico’s central bank has room to breathe.
Germany surprised to the downside: 2.3% in June, down from 2.6%. Energy inflation cratered from 6.6% to 3.4% — partly a temporary tax reduction, partly genuine demand softening. Services inflation held at 3.1%, though, so don’t pop the champagne yet. The ECB is watching services like a hawk.
The accelerators: South Korea, Canada, and India heat up
South Korea hit 3.2%, its fastest pace since December 2023. The culprit is a weaker won feeding through to import prices, plus raw material costs that just keep accumulating. Transport costs are up 11.1% year-over-year. The Bank of Korea’s 2% target is looking increasingly aspirational.
Canada also climbed to 3.2% — a 2.5-year high. Gasoline inflation exploded to 33.2% as the Middle East conflict disrupted energy exports from the region. Food isn’t helping either: fresh vegetables up 9%, fresh fruit up 5.3%. The silver lining: core inflation measures are holding steady around 2%, suggesting the Bank of Canada can look through the energy spike for now.
India rose to 3.93%, just below the RBI’s 4% target. Food inflation accelerated to 4.8% — the highest in 16 months — as the Middle East war drove up fertilizer and energy costs. India’s CPI basket is almost 46% food, so this matters enormously for household budgets. Personal care and miscellaneous goods hit a staggering 18.5%, though that category’s opacity makes it hard to diagnose.
Steady but sticky: UK, Japan, and China
The UK held at 2.8%, defying expectations of a jump to 3.0%. Transport surged 6.8% (motor fuels, air fares, vehicle taxes), but housing costs eased to their softest level in nearly two years and food inflation dropped to 2.2%. The net effect was a wash — but the composition matters. When transport is the only thing keeping inflation elevated, it’s usually transitory.
Japan barely budged at 1.5%, up from 1.4%. Here’s the thing about Japan: core inflation has been below the Bank of Japan’s 2% target for four straight months. Rice prices fell for the first time since 2022. Education is in outright deflation at -6.1%. The BOJ’s rate normalization narrative looks premature.
China is the outlier at 1.2% — unchanged from April, below consensus, and stuck in a low-inflation rut that’s starting to look structural. Food prices are falling (-1.7%). Transport is the only hot spot at 5.4%. The PPI is running at 3.9%, but that isn’t translating to consumer prices, which tells you demand is still weak. China exports deflation to the world.
What this means for the Fed
The global inflation picture is messy. Energy shocks from the Middle East are rippling through every economy, but the pass-through varies dramatically: Canada’s gasoline is up 33.2%, while Mexico’s energy barely budged at 3.27%. Policy matters. Subsidies, tax credits, and price caps buy time — but they don’t solve the underlying supply problem.
For the Fed, the takeaway is uncomfortable. U.S. inflation at 4.2% and rising, with core at 2.9%, makes a rate cut in July a non-starter. The June CPI print drops July 14 — if it shows another acceleration toward 4% on the headline, “higher for longer” becomes “higher, period.” The rest of the world is muddling through with a mix of luck (UK, Japan) and policy muscle (Mexico). America doesn’t have the luxury of either right now.
The next Trading Partner Inflation Check will be published the first week of August, covering June/July data. Stay tuned, stay profitable, and stay solvent.
