According to Yahoo Financethis investigation against Powell raises concerns about the independence of the FED.
Powell announced that the Department of Justice has subpoenaed the FED, threatening criminal charges for his testimony about building renovations. In a strongly worded statement, Powell said the move constitutes an escalation of President Trump’s campaign to pressure the FED to cut interest rates.
«The threat of criminal charges results from the Federal Reserve setting interest rates based on our best assessment of what will benefit the public, rather than following the president’s preferences,» Powell wrote, describing the concerns cited in the subpoenas as «pretexts.»
The responses against the accusations were immediate. «The alleged criminal investigation into Federal Reserve Chairman Jay Powell is an unprecedented attempt to use fiscal attacks to undermine (the Fed’s) independence,» says the statement signed by the former Fed chairs Janet Yellen, Ben Bernanke and Alan Greenspanas well as for four former treasury secretaries who served under Republican and Democratic presidents.
The analysts They do not expect the FED to make cuts this month after Friday’s December jobs report showed a continued cooling of the labor market without indicating a pronounced economic slowdown.
