The problem isn't for rate to come down to sub 1k levels.  The popular excuse is that the cost of goods and services are high or are going higher because of the growing USD<>NGN rate but we have had instance where the rate went down to 1k levels and what happened? Price of goods and services stayed the same.

Imo, best plan would be to solve economic issues and make sure that things like inflation that makes everything super expensive is eliminated otherwise, we'd just be shooting ourselves in the foot.
