Any chance it'll cause our credit rating to get cut?
Not directly. Our credit rating is based on us paying our bills. Since our bills are all in US Dollars, it doesn't matter how worthless they are for that purpose. If our bills were in Euros and the dollar plunged to $1000 to the Euro, we'd be in huge trouble.
Of course, if our currency crashed due to hyperinflation, we'll have all kinds of other problems which will probably lead to a loss of credit rating.
I've read some claims that this coin trick won't lead to hyper-inflation, but I just don't buy it. Maybe it's that I don't understand the complexities of the economics, but it sure seems like a bad idea from a monetary policy standpoint.
If they can make two of them today, they can just as easily make 200 next month, on a whim. I’d think that would give creditors cause for concern.
