If they dump the dollar for a new paper currency: it will hyperinflate
If they tie it to a basket of currencies: it will inflate, but not as much
If they tie to some sort of commodity, then it will not inflate, but it will have major disadvantages
If they raise interest rates and reduce money supply expansion, it will stabilize and not hyperinflate
There are many possibilities and they all depend on world trust in the dollar, the FED's control of the money supply, and the ability of the US to back the dollar with its economy and petro-dollar
