Nah, raising rate is just preparing for a potential financial crisis. It should start in Obama term, but Obama didn't want to end badly like Bush, so he pressured Yellen to delay until his term is over. FED is so called independent, but it is actually highly affected by politics. USA economy was strong in last a few years, but Fed was forced not to raise rates. Now, economy is slowing down, they can't raise rates. If another financial crisis comes, they have no weapon to defend financial system. Just my opinion
