How is the value of dollar determined?

For the first time in history the value of one US dollar has exceeded the 90-taka mark in informal market. The moment our economy started to recover from the coronavirus pandemic, the value of taka against the dollar started to go down.

The Daily Star's senior reporter AKM Zamir Uddin is explaining why the rate of taka is dropping in the international currency market in today's Star Explains.
