NCR regional inflation and Philippine commodity prices
PSA all-items Consumer Price Index for the National Capital Region. This page lists every Philippine commodity price whose monthly changes measurably track it, the delay between the two, and how much of the move carries through.
NCR regional inflation is an index or rate rather than a price, and it can sit near or cross zero. Percentage changes in a series like that are unstable, so the figures below are best read as direction and timing rather than as a “10% move produces X” rule.
The strongest link currently measured is Muskmelon* (Wholesale (PSA)), which moves with ncr regional inflation with a correlation of +0.39 at a lag of 6 months, measured over 79 overlapping months.

Correlation is measured on month-on-month percentage changes at the lag shown. Elasticity is the percentage move in the commodity per 1% move in the driver at that lag. Months is the number of overlapping monthly observations behind the estimate.
Last recomputed 2026-10-08.
How this is measured
- Both series are bucketed to monthly and converted to month-on-month percentage change, so a slow-drifting price level cannot manufacture a correlation.
- The commodity's monthly change is regressed on the driver's change at every lag from 0 to 12 months.
- The lag with the strongest correlation is kept; ties resolve toward the shorter lag.
- The link is labelled strong, moderate, weak or none from the correlation and its p-value together — strong requires a correlation of at least 0.5 at p < 0.01, moderate at least 0.3 at p < 0.05.
- Pairs with fewer than 24 overlapping monthly observations are excluded from every ranking on this site, however strong they score. With thousands of comparisons run each night, thin pairs clear a significance test on noise alone.
