I didn't do much research so lets assume you are right but at the same time I hope you do not confuse asset prices with consumer prices. The PCI in the USA is correct and people still cry that it is manipulated.

If the government is under reporting inflation that is a problem with the government. The obvious solution is to just report correct inflation. Once the government has reported correct inflation numbers the Turkish central bank must raise interest payments and that would mean at least 52% interest. The fundamental problem doesn't change though. People are still fleeing the influence of the Turkish government, not the currency. You need to trust the government and the government must eliminate internal corruption.
