Hungary received approximately 7.7 billion cubic metres of gas through Serbia during the 2025/2026 gas year. The Serbian corridor maintained its dominant role as total imports increased 2% to 12.1 billion cubic metres. The Serbian route accounted for roughly 64% of inbound volumes.
Other supply sources included Romania at approximately 2 billion cubic metres, Austria at 1.45 billion cubic metres, and Croatia at 0.9 billion cubic metres. Inflows from Ukraine were about 0.14 billion cubic metres.
Storage, throughput and domestic balance
Hungary increased storage injections by 37% to 3.14 billion cubic metres. This came alongside a 3% decline in total commercial volumes handled by FGSZ, which fell to 16.7 billion cubic metres. Domestic consumption remained broadly unchanged at 8.8 billion cubic metres.
Hungarian production held near 1.51 billion cubic metres. Exports decreased 20% to 4.75 billion cubic metres. Slovakia remained the largest destination, taking about 2.6 billion cubic metres, followed by Ukraine at roughly 1.7 billion cubic metres.
Border rules and corridor concentration
FGSZ and Romania’s Transgaz have aligned gas-quality rules at their border to simplify cross-border operations . Higher storage injections strengthened Hungary’s supply buffer, while imports remained heavily concentrated in the Serbian corridor . Alternative connections provide flexibility, while the southern route continues to carry most incoming gas.
