I think the surprise that you are talking about is already here as USDT is now currently exchanging at #918 in the P2P market and 912 on the spot market with all time high on P2P at 920 and sport 914, eh no go take time again for Naira to reach the 1k I doubt eh go even reach month end b4 we see our Naira dy trade 1k.
I believe this naira devaluation increase should be as a result of the CBN's "expansionary policy," which they believe could have helped the increase in value of the naira, but instead their plan goes against them, as naira circulation has increased to its all-time high (I read an article about this circulation increase sometimes last week, but I can't seem to find the link), maybe as a result of pumping in more naira into the system as a result of minimum wage increases in order to meet their target. But this is working sideways for them, as we have more Naira now attached with lesser value.
In order for the government to save our currency, they should restrategize, maybe by providing more dollar liquidity on the parallel market or by any other means of being more productive and reducing the high demand for foreign currency.
