the issue is how can they step in to help real estate when they will have to raise interest rates to prop the dollar imo
That is my thinking too. Which is at least a reason for caution. Fiscal policy is being driven by the exigencies of our large debt, considerably encumbering the FOMC. The dollar is near an historical low. It last got this low during the Reagan presidency. If it goes lower still, we will likely experience increased difficulty in financing the debt and higher rates would result. But in or favor is the vast dollar reserves held by central banks around the globe. These banks may be inclined to prop up the dollar to protect their own interests which includes not letting their currencies rise too far relative to the dollar. We shall see.
