Then on the night of Dec 20, he introduces a financial instrument where the government offers %14 interest and guarantees to pay the any difference if it happens that the lira devalues. With a coordinated effort, government banks start selling $USD the whole day and whole night when the markets are shallow and Turks are asleep, selling off at least 7B$ of the reserves of the central bank and who knows how much of other banks, lowering the $USD from 18 the night Turks went to bed to 11 at the morning.

Then they continued to sell off the national $USD reserves, conducting a full blown media propaganda operation including advertisement that is obviously produced at least days before the event. Looking back, just the day before the stock market crashed with %10 and there are rumours of certain businessman being informed that the government will change it's stance and intervene strongly.
Then we had the Economy minister bragging how they screwed up the little guy who bought $USD at over 14 in an attempt to protect their savings, adding that no institutional investors were harmed in the process.
It's just a crypto-bros level of shake off organised and executed by the government. They claim that the orthodox economists are to be blamed for the losses, how silly they are for not accounting for the government tricking the people. Imagine FED giving guidance for interest rates decrease then out of the blue dramatically increasing the rates at midnight once the pals of the president position themselves correctly and saying that the public shouldn't have listed to the economists.
At this very moment, Erdogan is having an "interview" that is broadcasted by multiple TV channels and as expected they again started selling off $USD as he began speaking, pushing the dollar from about 12 to 10.
