Bundesrat releases oil reserves: 19.5 million barrels against the price shock, diesel and heating oil first

What the Bundesrat decided on 16 October

On 16 October 2026 the Bundesrat approved a regulation from Economy Minister Katherina Reiche that releases 19.5 million barrels from the national oil reserve. This is Germany’s 4.9 per cent share of a G7 decision of 2 October to bring the pledged 400 million barrels fully to market. Around 3.5 million barrels had already been delivered from the March release; the remaining 16 million now follow. In return, the statutory stockholding obligation may fall temporarily from 90 to 82 days. The trigger, according to the ministry, is the high prices caused by the ongoing Iran war. Unlike in March, the regulation names no fixed product quantities — the oil stockholding association decides according to market conditions and brings diesel and heating oil first, then crude oil. How the fuel price feeds into the heat price is shown in the guide to heat costs per kilowatt hour.

Who a heating-oil and diesel release affects

Directly affected are households and landlords with oil heating, as well as businesses with high diesel and heating-oil demand — logistics, construction, agriculture, firms with their own tank storage. Heating oil stood at around €164 per 100 litres on average at the start of the heating season, well above the previous year. Indirectly, an easing on the crude market reaches the pump, so it touches anyone running a combustion-engine fleet.

Why the release caps the peak but not the trend

A strategic reserve is emergency cover, not an instrument of price policy — and it is exactly at this line that the release’s value is decided. It can dampen a price peak while supply is tight, but it does not replace lasting supply. In heating projects I have seen since 2021 that owners wait for a falling oil price before ordering — and then buy dearer, because the dip was shorter than expected.

The real catch is that the mandatory reserve drops from 90 to 82 days: a buffer that is needed in a tense winter becomes smaller. For anyone who intends oil to remain their lasting heat source, the release is no reason to wait. The lever that truly lowers the oil bill is the comparison with the alternatives — not the next announcement from Berlin.

What to do now

1. If you are planning an oil order, compare daily prices across several suppliers and use a release-driven dip deliberately, rather than betting on a lasting decline.
2. Businesses with large diesel or heating-oil demand should stagger their purchase volumes instead of covering everything on a single date.
3. For existing oil central heating, check whether rising fuel costs and the 2027 CO₂ price make a switch worthwhile — the benchmark is the comparison of heat costs per kilowatt hour.
