Gazprom UGS injection down 4% in H1 2026, storage build lags

Gazprom injected 18.9 bcm into its underground storage in H1 2026, a 4% year-on-year decline, signaling a slower refill pace ahead of winter. The reduction may reflect lower production or export constraints, but the company has not disclosed reasons. This could tighten European gas supply expectations if storage levels remain below seasonal norms.
