After a closely watched meeting, the Fed’s policy committee said it would cut a further $10 billion from its monthly bond-buying, known as quantitative easing (QE), and maintain its “highly accommodative” monetary policy of record-low interest rates.
Policymakers added in an upbeat statement that US economic growth “has rebounded in recent months” from the first-quarter contraction, while household spending and business investment were both rising.
– Yellen upbeat on economy –
The committee “believes that economic activity is rebounding in the current quarter and will continue to expand at a moderate pace thereafter,” said Fed chief Janet Yellen said at a news conference.
There was no mention of an earlier hike in interest rates than mid-2015, providing dealers with at least another year of ultra-cheap money. There had been speculation that a recent run of upbeat economic data — including rising inflation — would prompt the Fed to consider bringing forward its timetable.
“The Federal Open Market Committee reiterated pulling the plug on QE in measured steps as the economic growth continues to bounce back,” said Capital Spreads analyst Jonathan Sudaria.
“At the same time the Fed stood by their previous decision to keep interest rates at record low levels for a considerable time.
“Investors took joy in those reassurances,” added Sudaria.
