They could destroy Turkiyes economy with relatively few sanctions, look at Trump during the pastor/halk bank scandal as an example.
The US says the move is a response to Turkey’s failure to release jailed US pastor Andrew Brunson.

The economy and its terrible performance is based on erdoeconomics and rampant corruption from top to bottom. The recovery process during the first 5 to 7 years was developed primarily by kemal dervis, a real economist with international accreditation. Once AK party left that behind the economy kept getting worse and worse and looking forward if he wins you can guarantee that Turkiye becomes a poorer and poorer country. So a vote for AK party 100% means that the average Turkish citizen will be made poorer. We have seen absolutely nothing to suggest that this man knows anything about state economics. Putting his pathetic other son in law in charge of the central bank exposed how lacking this man is as a statesman.
But on a side note the reason the Americans can't go down the line of destroying the Turkish economy outright is for several reasons. Too many western corporations make good business from Turkiye, so destroying the Turkish economy will economically cost the USA/West money.
Then their is the geopolitics, nearly the entire middle east doesn't like the Americans operating there. Outside pkk terrorists and a few lackeys dictators the americans are seen as two faced instigating trouble makers of the region and the biggest supporter of isreal, which outside Turkiye is generally despised by the rest of the middle east. Go after Turkiye's economy and the Americans will be dumped out of Turkiye and most likely their entire position in the region will come into question.
Then they lose the advantage of Turkiye geography being used to contain Russia. So they won't go after Turkiye's economy what they will do is things like feto, take the country from within and people will not even notice it.
Sanctions and embargoes can only ever be used to a degree to manipulate Turkish actions in the direction that favours US regional policy. They go too far and their entire position in the region is undermined.
But as far as this terrible economy is concerned its 90% rests on AK party and terrible performance.
