A recession is commonly defined as two successive quarters of contraction.
The institute forecasts economic output in 2023 will remain at roughly the same level as the year before, contracting by 0.1%.
In contrast, the German government expects growth of 0.2% this year, and another leading German economic institute, the IfW, raised its growth forecast on Wednesday to 0.5% from 0.3%, saying easing bottlenecks should contribute to an upward trend.
Both institutes predict the economy will recover in 2024, with Ifo foreseeing growth of 1.7% and IfW 1.4%, and inflation will remain stubbornly high this year before falling next year.
In 2023, inflation is expected to fall to 6.2% from last year's 6.9%, while in 2024, it will decline to 2.2%, according to Ifo.
Similarly, the IfW sees consumer prices rising by 5.4% this year and by 2.1% next year.
"We have reached the peak of inflation," said Ifo economic
researcher Timo Wollmershaeuser, citing falling energy prices
and an easing of supply chain bottlenecks. However, the strong
increase in wages is creating new price pressure, he added.
"High inflation is reducing households' disposable incomes
and leading to a decline in private consumer spending in the
current year," the IfW said. A "noticeable loss of purchasing
power" of 1.8"% is on the horizon, added the institute.
