The latest round of GST rate cuts is showing up most clearly where consumers feel it fastest—on big-ticket discretionary purchases such as cars, two-wheelers and household durables.
Prices in consumer electronics and automobiles fell sharply between September and December 2025, marking a far stronger pass-through than seen in recent years, according to an analysis of item-level Consumer Price Index (CPI) data.
Across items most directly affected by the GST reductions, average prices declined 3.6 percent over the September–December period. This is a stark contrast to the same months in 2024 and 2023, when prices in these categories barely moved, falling by just 0.3 percent on average. The data suggests that where tax cuts were deep and demand is relatively elastic, firms moved quickly to pass on the benefit to consumers.
The sharpest declines were concentrated in categories where GST rates were cut the most. Items mapped to an average GST reduction of about 7.8 percent saw prices fall 3.6 percent in 2025. In comparison, the same set of items recorded a marginal increase of 0.2 percent in 2024 and a 0.4 percent rise in 2023, underscoring how unusual the latest price adjustment has been.
Automobiles stand out most clearly. Prices of motor cars dropped 7.3 percent between September and December, while motorcycles and scooters became 4.6 percent cheaper. These are categories where GST cuts were substantial, and competition is intense, making it easier for manufacturers and dealers to reflect tax changes quickly in showroom prices.
Household durables also saw meaningful relief. Washing machines recorded a 4.2 percent fall in prices over the three months, air-conditioners and air coolers declined 3.0 percent, televisions fell by a similar margin, and refrigerators became about 2.2 percent cheaper. Together, these moves suggest that GST changes are filtering through fastest in durable goods that involve larger, infrequent purchases and clearer price tags.
The picture is very different for everyday consumables. Even where GST rates were slashed sharply—such as edible items moved to the 5 percent slab from 18 percent—the pass-through has been limited. Candy prices declined just 1.8 percent over the period, while biscuits and chocolates saw a modest 1.2 percent drop.
A similar pattern is visible in categories shifted from the 12 percent slab to 5 percent. Products such as coffee, bicycles, toilet soap, toothpaste and other toiletries recorded only small declines. On average, across 51 CPI items affected by GST changes, prices edged down by just 0.11 percent between September and December 2025. That compares with a 1 percent rise over the same months in 2024 and a 0.33 percent increase in 2023.
Even within this group, the relief has been uneven. Toilet soap prices fell 1.5 percent, while toothpaste became only 0.33 percent cheaper over three months, indicating that firms in fast-moving consumer goods may be absorbing part of the tax cut through margins rather than fully passing it on.
By contrast, items where GST rates were left unchanged showed little deviation from past trends. These categories saw prices rise 0.67 percent between September and December 2025, broadly in line with the roughly 0.6 percent increase recorded over the same period in the previous two years.
