In BFIs and share market, there is clean and clear record of trail of money so no one would expose black money here. Unless you are hiding prachanda's black money like prachanda's ex gharpati.
Black money is in meter byaj and cooperative. That is why corrupt politician has been promoting cooperative. 3 khambe economy

I think there are three main reason, corrupt politician like yuraj k has been promoting cooperative. Another reason is, I think, politicians and their workers are being fed/paid using cooperatives money in the name of bhatta, director's salary etc.
In share market, all payments are made through bfis. And they have been watching bfis for years now.
No physical impact of latest circulation. Mental, may be for first three hour.
And remember, for last couple of week, except for last few days, big players have been dumping share to bring down the market. So, if latest circulation, if effects, it will be on those sellers. Not buyers.
Hope there is less seller and many buyer tomorrow.
