tocks slid on Friday after Federal Reserve chairman Jerome Powell said he was prepared to raise interest rates further to keep inflation at bay.
European markets had been sitting pretty on Friday afternoon until the hawkish speech at the Jackson Hole central banking conference.
Wall Street unsurprisingly plunged after the opening bell following the speech, with the FTSE among indices to swing down into the red as a result.
“Powell’s decision to reiterate the central importance of combatting inflation over growth does highlight the willingness to maintain the upward trajectory for rates in the face of economic suffering,” said Joshua Mahoney, senior market analyst at IG.
“While markets have recently taken solace from the tick lower in inflation, today served to highlight the fact that we remain a long way from the position where rates can be brought under control once again.
