Germany will fall into recession next year, a leading think-tank warned Monday, with Europe’s biggest economy facing soaring inflation as Russia slashes energy supplies. The Ifo institute expects the German economy to shrink 0.3 percent in 2023 — slashing its forecast by four percentage points from a previous prediction in June. Inflation is expected to hit 8.1 percent this year and 9.3 percent next year, it said. “We are heading into a winter recession,” said Timo Wollmershaeuser, Ifo’s head of forecasts. “The cuts in gas supplies from Russia over the summer and the drastic price increases they triggered are wreaking havoc on the economic recovery following the coronavirus.” Real household incomes and purchasing power will drop sharply, the think-tank warned. There is likely to be a “return to normal” in 2024 with 1.8 percent growth and 2.5 percent inflation, Wollmershaeuser said. At the start of September, Russian energy giant Gazprom halted gas deliveries to Europe via the key Nord Stream 1 pipeline saying it would be under repair for an unspecified period. The shutdown accentuates an energy crisis in Germany, long reliant on Russian gas, and across Europe, with Moscow accused of using energy as a weapon amid tensions over the Ukraine war.
