It can only cause inflation when the money actually hits the economy. The effect would be no different than raising the debt ceiling. Some special book keeping (which is what this whole mess is) will do nothing by itself.
the coin doesn't hit the economy but it enables further borrowing which does.
surprised at all the 'no this is actually quote ok' arguments. you can't print value out of thin air. you only print volume which taxes the holders of existing USD.
