Khafee my dear,
In a nutshell a double edged sword.
Primarily FATF is part of US led Global Financial Architecture... SWIFT being one infrastructural piece of it. That's why China developed its own counter to SWIFT. So is Russia trying.
Anyhow, primarily its on the surface to stop money laundering. All banks need to be compliant, including central banks.
EU is already compliant.
Coming back to Pak... well, honestly bank banking and financial sector is complicit in the black money moving operations of the #CriminalEnterprise... all private banks are owned by the Pak elite anyways.
SBP was looking the other way when untracked/validated money was moving around. Still is too an extent. Then there is unofficial money transfer through hundi or so.
FATF on its positive end makes money trackable. So, coming out of grey list would help stopping money laundering out of Pakistan.
Zardari/Sharifs money laundering is a case in point.
On the negative end it would create intrusive impact for financial sector. A pressure tool by India and her masters.
Herein Pak State needs to have a long term Financial Security Policy.
However, the level of mess in all sectors of economic infrastructure... such a policy is going to take a bit more time.
Regarding data of individuals .... Bank of International Settlements has data of every human being on the planet.
We are going through a phase of global power flux. I suspect a parallel Financial Architecture to emerge.
UAE can play as a bridge for both worlds... can become a clearinghouse.
Hope it helped.
