Wage growth cools

March’s payroll release showed paychecks are no longer pulling prices higher the way they did during the post‑pandemic boom: average hourly earnings rose just 0.2 percent from February to March and 3.5 percent year‑over‑year, the smallest annual gain since May 2021. (bls.gov) That cooling in nominal wage growth arrives while two other forces are nudging consumer prices the opposite way: newly large U.S. tariffs on imports, and a spike in oil and fuel costs tied to the Iran war. (nbcnews.com) Tariffs work like a hidden tax on goods sold in the United States. When an importer pays a new duty, that cost usually doesn’t disappear — most of it shows up as higher retail prices because foreign sellers and U.S. middlemen do not fully absorb the levy. Recent research and trackers of the 2025–26 tariff program find very high “pass‑through” rates, meaning tariffs translate quickly into higher consumer prices for traded goods. (nber.org) Fuel is a different channel but the same story: higher diesel, jet fuel and gasoline raise costs for trucking, shipping and airlines, and firms often pass those costs on to customers. Analysts and policy shops now call the combined effect a war‑related “tax” on U.S. households because it raises the price level even without any extra consumer demand. (cnbc.com) Those two supply‑side pressures create a classic identification problem for the Federal Reserve and other central banks. Monetary policy can lower demand — by raising interest rates to cool hiring and spending — but it cannot directly remove a tariff or force crude oil prices down. If rising prices come from supply constraints, tightening policy risks slowing growth and raising unemployment without doing much to lower the underlying cost shock. (federalreserve.gov) Markets are wrestling with this ambiguity. Ten‑year Treasury yields have moved in recent weeks around the low‑to‑mid 4 percent range as investors price both persistent inflation risk and the possibility the Fed will stand pat instead of cutting quickly. Those moves reflect shifting expectations about future inflation and real rates rather than a single clear signal about demand. (fred.stlouisfed.org) For an econometrics project that nails this question, compare regions and industries that faced larger tariff exposure or higher shipping intensity against those that did not, and test whether local price levels rose more than wage growth fell. Use the BLS wage and payroll series, the Atlanta Fed’s micro‑based Wage Growth Tracker to follow individual‑level nominal changes, product‑level import duty data from tariff trackers, and daily retail price panels such as the Harvard Business School Pricing Lab. A difference‑in‑differences design plus a structural VAR that separates a supply shock from a demand shock will give you both identification and a time‑series narrative suitable for a trading‑strategy pitch or a policy brief. (bls.gov) The concrete point to take away: wages are cooling, but headline inflation may rise anyway because of tariff and fuel shocks that act like taxes. That mixture forces the Fed to ask whether higher prices reflect too much spending or a cost shock it cannot easily neutralize — a policy puzzle markets and grad‑student projects are now racing to untangle. The Fed’s next two‑day policy meeting is scheduled for April 28–29, where officials will be parsing exactly this kind of evidence. (bls.gov)
