Tomorrow’s costs, today’s prices: why expectations matter for inflation

Boromeus Wanengkirtyo, Ivan Yotzov and Mishel Ghassibe

Can tomorrow’s costs affect firm prices today? When a temporary tariff schedule on imported inputs was announced in March 2019, many UK firms adjusted prices in anticipation – despite the potential cost change being in the future. In a recent working paper, we use firm‑level survey data to estimate ‘intertemporal pass‑through’ (IPT): how much expected future marginal costs move current prices. Consistent with modern macroeconomic theory, we find big differences across firms: those that change prices less often, and expect the shock sooner, responded the most. A model shows this variation across firms makes aggregate inflation more forward‑looking, so announcements of future policies can move inflation today.

Monitoring trade prices in the wake of trade tensions

Marco Garofalo and Thomas Prayer

The US administration raised US import tariffs in April, reigniting trade tensions. This sparked concerns about cheaper exports being diverted to other markets, potentially lowering global prices. Using detailed product-level data, we build a novel timely indicator to consistently track trade prices across countries. Chinese export prices have risen less than global ones since April and remain below March levels. Prices of other Asian exporters, Canada and Mexico have also grown more slowly than global prices, but to a more limited extent, while export prices for Europe grew faster than global patterns. UK import prices mirror those in Europe, whereas US import prices (excluding tariffs) have declined since March 2025. Our results and future updates are publicly available online.
