that’s hedgefund billionaire bill ackman sounding off on twitter tuesday blaming a timid federal reserve for not doing enough to signal to investors that it’s committed to getting inflation under control the fed must pledge to do “whatever it takes” and follow it up with a series of aggressive rate increases he argued read the whole thread for the flavor ackman’s beef is that the fed despite raising rates by an outsize 50 basis points or half a percentage point earlier this month and signaling at least two more halfpoint hikes are in store at coming meetings is set to remain well behind the curve “in the last day or so various current and former fed members have waffled and made dovish remarks proposing a modest increase in rates and a pause in the fall” he said “the fed has already lost credibility for its misread and late pivot on inflation” atlanta fed president raphael bostic on monday said a september pause in rate increases to reassess could make sense according to news reports pushing the fedfunds rate up by 300 basis points from near zero while inflation is running above 8 year over year and unemployment stands at 36 is a recipe for doubledigit inflation that can otherwise “only be forestalled by a market collapse or a massive increase in rates” ackman said ackman’s remarks came as stocks fell sharply tuesday seeing renewed pressure after a monday bounce the dow jones industrial average djia was down 330 points or 1 while the sp 500 spx slumped nearly 2 to trade just below 3900 a finish below 383725 would see the largecap benchmark officially enter a bear market the nasdaq composite comp  which entered a bear market earlier this year was down more than 3 “markets are imploding because investors are not confident that the federal reserve will stop inflation” he tweeted and as a result the market is doing the fed’s job for it
