"The social gap is widening at the moment, and even more than during the pandemic," Fratzscher told German media.
Since people with low incomes are spending a majority of their income on basic supplies such as energy and food, they are feeling the effects of inflation three times as strongly as those on high incomes. A similar trend can also be seen among German companies.
"Some of the big players are making big profits even in these times, while many medium-sized companies... are barely surviving," Fratzscher said.
A study published by the Institute of Economic and Social Research at the Hans Boeckler Foundation found that the financial gap between households below the poverty line and the median income had already grown significantly before the start of the COVID-19 pandemic.
This development was an "extremely poor starting position for the continued social stress tests" caused by the ongoing pandemic, the Russia-Ukraine conflict and record inflation, the foundation said.
Inflation in Germany climbed to 10.4 percent in October, the highest level since 1990, according to the Federal Statistical Office. The development was mainly driven by rising energy and food prices, which were up by 43 percent and 20 percent year-on-year, respectively.
