In view of the high inflation in the US, US Treasury Secretary Janet Yellen has admitted that she was wrong in her earlier assessments.
"I think I was wrong at the time about the course of inflation," Yellen told CNN on Tuesday (local time).
She underestimated the economic shocks caused by factors such as high energy prices and international supply chain problems.
Yellen said in May last year that she did not expect inflation to become a problem.
In April, consumer prices rose by 8.3 percent compared to the same month last year.
US President Joe Biden said in a meeting with Yellen and Federal Reserve (Fed) Chairman Jerome Powell on Tuesday that fighting inflation is his top priority.
He also pledged that he would continue to respect the Fed's independence.
Powell is also concentrating on fighting inflation, just like himself. The central bank is already fighting the high inflation rate with a tighter monetary policy.
In early May, Powell said he believed the Fed was getting a "soft landing."
What is meant is that it can successfully lower inflation without triggering a recession in the United States.
US interest rate hikes
Most recently, the Fed had intensified the fight against the ever faster rising inflation in America with the highest interest rate hike in 22 years.
It raised the key interest rate by half a percentage point between 0.75 and 1 percent.
The US Senate confirmed Powell for another term as Fed chair by a large majority almost three weeks ago.
The Democrat Biden had already nominated the 69-year-old for four more years in November.
Powell has headed the central bank of the world's largest economy since February 2018. The then President Donald Trump, a Republican, had nominated him.
Powell has been a member of the Federal Reserve Board since 2012.
For the euro area, the European statistical office announced its inflation estimate for May on Tuesday.
Accordingly, the value is now more than 8 percent.
