I believe every country, except those that have joined economic unions under certain conditions, retain the power to create money.  For instance, in the US, the Federal Reserve (which is a governmental agency that's only independent in the sense that executive discretion is extremely limited) controls the money supply, and if Congress really wanted to (and had agreement from the president or dual super-majorities), it could direct the Federal Reserve to create more money.  This is an inherent power of national governments.
