Dutch Inflation Confirmed at 3.4% in September as Fuel Prices Push Costs Higher

Consumer prices in the Netherlands were 3.4% higher in September than a year earlier, Statistics Netherlands (CBS) confirmed on Tuesday, October 13, as sharply rising motor fuel costs lifted inflation from 3.3% in August. The final reading matched the agency’s October 2 flash estimate, but the detailed figures show how expensive fuel outweighed some relief from falling food prices.

The annual inflation rate has risen for three consecutive months, from 2.9% in June to 3.2% in July, 3.3% in August and now 3.4%. September’s figure measures the average change in consumer prices since September 2025, not the increase in household costs during September alone. It points to persistent price pressure even though different parts of the consumer basket are moving in opposite directions.

The final figures published by CBS show that prices rose 0.1% from August to September. That relatively small monthly move is distinct from the annual rate, which compares the current price level with the corresponding month a year ago. CBS cautions that monthly movements can also reflect seasonal patterns, such as temporary sales, rather than a lasting change in the inflation trend.

Motor fuel prices drive the increase

Motor fuels were 27.2% more expensive in September than in the same month of 2025, up from a 23.4% annual increase in August. CBS identified fuel as the main reason headline inflation edged higher. Diesel recorded the sharpest increase among motor fuels, underscoring the pressure on drivers and businesses that depend on road transport.

The average price of diesel reached €2.499 per liter in September, compared with €2.369 in August. Petrol averaged €2.448 per liter, up from €2.333 the previous month. Those pump-price comparisons capture the rise over a single month, whereas the 27.2% fuel inflation figure measures a full year. Keeping the two time frames separate matters when judging how quickly costs are changing.

The price increases are especially visible for motorists, although the CPI covers far more than personal travel. Transport includes other expenses, and the aggregate inflation rate reflects the spending patterns used in the national index. CBS also identified higher mobile phone charges as an upward influence on September inflation, so the acceleration was not exclusively attributable to energy.

Fuel’s influence also comes at a time when the annual CPI reading has been moving unevenly. Inflation was 3.5% in May, then fell to 2.9% by June before rising through September. The current 3.4% rate is therefore above its early-summer level but below May’s reading, rather than a new peak for the year. For households, that distinction does not remove the impact of higher prices, but it puts the latest increase in context.

Food offers relief, but housing and transport weigh heavily

Food prices moved in the opposite direction. CBS said food was 1.7% cheaper than a year earlier in September, compared with a 0.7% annual decline in August. The faster fall helped restrain overall inflation. It does not mean that every grocery item has become cheaper, only that prices across the category were lower on average than in the corresponding month last year.

In the CPI contribution breakdown, food and non-alcoholic beverages subtracted 0.21 percentage points from September’s annual inflation rate, compared with a negative 0.11-point contribution in August. These are contributions to the 3.4% overall figure, not the percentage change in food prices themselves. The distinction helps explain how headline inflation can rise despite consumers seeing lower average prices for one major category.

Housing and utilities accounted for 1.03 percentage points of September inflation, up from 0.99 points in August. Transport contributed 1.02 points, compared with 0.95 points the month before. Both categories were among the largest positive contributors to the headline rate, indicating that the pressure extended beyond the food basket, with transport’s larger contribution consistent with the sharp rise in fuel costs.

Spending by Dutch consumers abroad added 0.42 percentage points, up slightly from 0.40 points in August. Restaurants and accommodation services contributed 0.30 points, compared with 0.27 points previously. Recreation, sport and culture added 0.26 points, up from 0.20. These figures help show where price pressures are concentrated without implying that every expense rose at the same rate.

Information and communication moved from a negative contribution of 0.05 percentage points in August to a positive 0.05 points in September. That shift is consistent with CBS’s observation that mobile charges helped push inflation up. Meanwhile, the contribution from miscellaneous goods and services eased to 0.23 points from 0.27, another example of how offsetting changes can sit behind a relatively small movement in the headline number.

The Dutch rate differs from the eurozone measure

For comparisons across Europe, CBS also publishes an inflation rate using the Harmonised Index of Consumer Prices (HICP). On that basis, Dutch inflation was 3.0% in September, up from 2.8% in August. Euro area inflation rose more sharply, reaching 3.8% from 3.2%. The Dutch national CPI rate of 3.4% should not be compared directly with the euro area’s 3.8% HICP reading as though they were calculated in the same way.

One important difference is the treatment of home ownership costs. The Dutch CPI includes an estimate of those costs based on changes in housing rents, while the HICP excludes owner-occupied housing costs. The European harmonised series is designed to improve comparability between countries, so its 3.0% reading is the appropriate Dutch counterpart to the euro area’s 3.8%.

The regional comparison also reveals where Dutch prices are behaving differently. In the HICP breakdown, food, beverages and tobacco prices fell 1.2% in the Netherlands from a year earlier, while they rose 1.4% across the euro area. Energy, including motor fuels, increased 14.0% in the Netherlands against 18.8% for the euro area. Services showed the reverse pattern, rising 3.8% in the Netherlands and 3.2% across the currency bloc.

Both Dutch inflation measures have used 2025 as their index base since January 2026, replacing the previous 2015 base. That statistical reference year is separate from the published annual inflation rate, which still compares prices with the same month in the previous year. September’s final CPI figure remained at the 3.4% first reported in the flash estimate, while the fuller release identified the rising fuel bill and the offset from cheaper food behind the result.
