Did rice tariffication lower retail prices? A regional analysis, 2019–2026

Short answer → Tariffication reduced well-milled rice prices by 8–12% in Metro Manila and Central Luzon, but the effect was smaller and slower in Visayas and Mindanao.

Abstract

Republic Act 11203 replaced quantitative limits on rice imports with tariffs in 2019. This paper estimates how much of the change reached retail prices of regular- and well-milled rice across Philippine regions, using monthly price surveys from 2019 to 2026.
