Belgian Inflation Accelerates to 3.97% in August, Approaching 4% Mark
Belgian inflation accelerated for the second consecutive month in August, climbing to 3.97% from 3.56% in July, according to the country’s statistics office Statbel. The consumer price index rose 0.41 points (0.40%) to 104.01 points (2025 = 100), bringing the annual inflation rate closer to the symbolic 4% threshold.
The acceleration marks a notable shift from the early months of 2026, when inflation stood well below 2%. After surging past 4% in April amid the Middle East conflict, prices moderated through June and July before the current upward trend resumed.
Energy Prices Drive the Surge
Energy inflation jumped to 16.47% in August, up sharply from 10.59% in July, contributing 1.44 percentage points to total inflation. Natural gas prices rose 24.9% year-on-year, a significant escalation from the 10.3% recorded in July, with a 9.8% monthly increase in August alone. Diesel prices climbed 33.4% year-on-year, while gasoline rose 19.9%.
According to 21news.be, the high energy prices remain a direct consequence of the conflict in the Middle East and the closure of the Strait of Hormuz. However, there may be relief on the horizon: Iran and Oman are reportedly negotiating the reopening of the critical shipping chokepoint, with a “temporary corridor” under discussion. Brent crude oil is currently trading at $88.1 per barrel, down from roughly $95 the previous week.
Core Inflation Eases Despite Headline Rise
Despite the headline acceleration, core inflation — which excludes volatile energy and food prices — declined from 3.13% in July to 2.99% in August. The health index, used for wage indexation and rent adjustments, rose to 3.44% from 3.22%, while the smoothed health index stood at 100.94 points.
The next pivot index (spilindex) for public sector wages and social benefits is set at 102.29 points. As VRT NWS previously reported, the spilindex was crossed in June 2026, triggering automatic indexation of social benefits in August and public sector wages in September.
AI Race Drives Storage Device Prices
The largest single price increase recorded in August was for external storage devices — hard drives, USB sticks, and SD cards — which rose 45.1% year-on-year. This surge is attributed to the AI boom, as data centers massively purchase storage capacity for artificial intelligence development. Package holidays rose 19.9%, while medicines increased 16.8%.
On the other end of the spectrum, fresh berries fell 15.3%, powerbanks dropped 12.2%, and smartphones declined 10.2% compared to August 2025.
Implications for Consumers and Policy
For an average household, the 3.97% inflation rate means that a shopping basket costing €100 in August 2025 now costs approximately €103.97, as HLN notes. This erosion of purchasing power is particularly acute for energy-dependent expenses.
The European Central Bank has warned that eurozone inflation in 2026 will be higher than previously expected, projecting an average of 2.6% with a temporary peak of 3.1% in the second quarter. As Nieuws365 notes, higher energy costs may also feed into food inflation over time.
Belgium’s automatic wage indexation system provides some protection, though the new “centenindex” caps indexation at €2,000 per month for social benefits and €4,000 for public sector wages. Higher-income earners will see less complete protection from automatic indexation.
What to Watch Next
The trajectory of energy prices remains the key variable. If the Strait of Hormuz negotiations succeed, energy costs could ease significantly. However, the Federal Planning Bureau’s earlier forecasts have consistently underestimated inflation, suggesting continued upward pressure may persist. The HICP flash estimate for Belgium stands at 4.2% for August, indicating the European-harmonized measure remains above the national figure. The next spilindex crossing is projected for December 2026, with another expected in August 2027.
