My short answer is that every country that controls its own central bank is in charge of its own inflation rate, because it's a matter of supply and demand for money. The euro area has a common currency, so to some extent, they can say it's a bit of an international problem affecting the euro area, but every central bank controls the value of its own currency. We have our own central bank. We sometimes talked about adopting another currency, such as the U.S. dollar. We decided not to, because we wanted control over our own currency.
We have control over our own currency. It's up to us to determine our inflation rate.
