Nope, their governments are just supporting the currency and keep it at a range beneficial for their economic system. Egypt had similar system,but everything got missed when the economy dropped.
So, as long as these country economy is ok, they can support their currency. Otherwise, it will be open to trading and price will shift.
Free price is better in my opinion. These situation will surely lead to economic problem, now or later.
So, in my opinion, these currencies are very far from gold. Gold is staple while being open to trading.
