# German energy price volatility and rising costs > Live situation record from CLSTR: https://clstr.news/situations/german-energy-price-volatility-and-costs > Updated: 2026-09-26T17:50:23.000Z. Sources: 33. Developments: 4. Germany continues to face significant energy cost pressures and market volatility. Electricity prices for new customers have risen approximately 28 percent since the June low, with the average cost for the cheapest available tariff increasing from 23.47 cents per kilowatt-hour to approximately 30.11 cents by late September 2026. This upward trend is largely driven by rising gas prices influenced by geopolitical tensions in Iran and the situation around the Strait of Hormuz. Due to the merit-order principle, gas-fired power plant costs often determine market prices when renewable supply is insufficient. Regional variations remain high, with rates ranging from roughly 25.54 cents per kWh in Bavaria to 41.12 cents in Baden-Württemberg. Fuel pricing remains a volatile concern. While some relief has been noted in diesel prices, gasoline and diesel have hit record highs due to rising crude oil costs. Geopolitical instability in the Middle East and potential blockades of the Strait of Hormuz continue to drive supply concerns, with the International Energy Agency noting significant drops in oil transit during peak conflict periods. Specifically, oil transit through the strait dropped to approximately eight percent of global trade in August, contributing to global oil prices occasionally exceeding 100 dollars per barrel. In Germany, record-high fuel prices are driving inflation, with economists predicting it could rise to 3.2 percent in September, the highest level in nearly three years. To mitigate this, the German government has approved a temporary fuel tax reduction of approximately 17 cents per liter, effective from October through the end of 2026. Meanwhile, European natural gas inventories sit at roughly 71 percent capacity, below the five-year seasonal average of 87 percent. Experts warn gas prices could exceed 100 euros per megawatt-hour this winter if supply shortages coincide with severe cold weather. ## Claims - A fuel tax reduction of approximately 17 cents per liter will be implemented from October to the end of the year.
