The US Senate passed a string of fiscal measures aimed at increasing American incomes by a very small majority (51-49). Postponing the description of the main measures of this document to another time, the issues that its approval places are described. The first is the time it will take to reconcile with the proposal passed in the House of Representatives. The second is to try to anticipate (as much as possible) what the real effects will be on the real economy. The third concerns the impact it will have on the public deficit. If it is very significant, it may imply a generalized rise in yields, which will cause a profound change in the global stock market situation. The fourth, which depends a little on the others, is to know how much of the positive effects of this reform have been anticipated by the extraordinary rise of American markets in recent months.
