PTI and PMLN both same coin no difference.
PMLN forced negative interest rate PTI did the same, which lead to CAD
PMLN overvalued the currency too much PTI is doing the same REER right now is at 95 and it is undervalue and still import are increasing and export are flat no increase at all.
Hired a person who is failed banker, did a fraud in 2009 with PPP and IMF and did a fraud again with Senate, IMF, PM and NA that our CAD will be only 2.3 billion this whole FY and signed it to IMF.
PTI used 5.8 billion dollar in 4 years and 1.2 billion dollar in last 3 months to control PKR value against dollar due to Shaukat Tarin request.
Among them all the best is PPP because they increased export to 31 billion dollar in 2011 and never forced Interest rate to negative due to when PPP left the CAD in 2013 was only 2.5 billion dollar.
Externally PPP was better than PMLN and PTI.
