Lähtevaru

Lähtevaru is a Finnish term used to describe a reserve of essential resources kept to ensure continued access during disruptions to supply. The concept is commonly applied in energy policy, critical materials management, and resilience planning. A lähtevaru may consist of physical stockpiles of commodities such as oil, natural gas, coal, or key metals, as well as mechanisms like long-term supply contracts, diversified import sources, and capacity reserves in power systems.

Management of lähtevaru typically involves government authorities or public agencies, sometimes in partnership with industry. The size and composition are determined by risk assessments, vulnerability analyses, and strategic policy objectives; common metrics include days of consumption covered or monetary value of stock. Release triggers can include a severe disruption, a sharp price increase, or a directive to prioritize critical sectors. The aim is to dampen price volatility, reduce supply risk, and maintain essential functions.

Translations and equivalents vary; in English-language policy literature the terms most closely related are strategic reserve or buffer stock. The Finnish term highlights the idea of guarding the source of supply and is often integrated with broader resilience strategies. Critics note that reserves entail costs, potential misallocation, and limited effectiveness if underlying vulnerabilities (such as infrastructure, logistics, or demand patterns) are not addressed.
