Treasury Secretary Janet Yellen testified before the Senate Finance Committee on Tuesday and warned inflation will remain high.

Treasury Secretary Janet Yellen: “We currently face macroeconomic challenges, including unacceptable levels of inflation, as well as the headwinds associated with the disruptions caused by the pandemic’s effect on supply chains and the effects of supply-side disturbances to oil and food markets resulting from Russia’s war in Ukraine.”

Yellen’s comment comes as the World Bank has warned stagflation in the global economy could have potentially destabilizing consequences in some countries including the rising risk of malnutrition and even famine.

Meanwhile, U.S. Federal Reserve Chair Jerome Powell has faced some criticism after recently saying one of his goals in combating inflation was “to get wages down.”
