The same Mafia that is freely playing with black market rates, is not only covering up, but encouraging hike of prices, especially in household and common consumer products, since they provide through this direct mass theft, needed cashflow to keep the exchange robbery going, and at the same time, help with emptying people's bank accounts from dollars, making it easier for the banking system, and hence the thieves behind it, to get away with the stolen money from people's accounts.
That same stolen money that has already been transferred outside Lebanon, and that banks are giving back in tiny amounts, from merely part of its interests, and at an 85% discount rate.
