I have no dog in this hunt but there's a problem with taking numbers at face value and not doing any deeper analysis.
1) The inflation rise under PTI is not as severe when you put it in historical context. Firstly they inherited inflation at 6% not 3% when you look at State Bank figures. In the first six months of PPP government, inflation skyrocketed from 11 to 25% while under PMLN inflation climbed from 5% to 11%.
Necessary currency devaluation and international oil price rises has also contributed to inflation.
2) The rupee was being overvalued by PMLN to fund imports and burned up your foreign exchange reserves. The rupee is now much closer to the real exchange rate.
Circular debt was Rs1.4trn when PTI took office. It has increased, but the rate of increase has slowed compared to PMLN's last year. As for slower GDP growth, one of the reasons is that foreign investment has slowed down due to CPEC transitioning from Phase 1 to Phase 2. However when you exclude China, FDI inflows have increased by nearly 20%. I don't know enough about the causes of the other issues you raise.
Well, we need to see things in perspective.
1. Inflation in March 2018 was 3.2 %. We need to see where it stands today.
We also need to see that what was inflation when PML N took over from PPP and how inflation panned out in next 5 years.
2. Devaluation of Rupee has crashed the economy with it. Hence, this proves that Dar was right. After all what you got from this massive devaluation of Rupee ? All the dips I mentioned.
PTI and it’s thinktank (if any) thought that this would curtail imports massively and would give huge kick to Exports. This theory has died its natural death. There is only a minimum decrease in import bill and Exports just rose around 1 %
3. As far as foreign exchange reserves is concerned before Panama debacle it was during PML N tenure that we raised it upto 24 Billion Dollars (Pakistan’s record). Now compare these to PPP tenure.
Still post exploitation Panama Leaks by State arms Political aswell as economic instability had its toll on foreign exchange reserves aswell. Still they were 19.4 billion Dollars when PML N left and now after borrowing of 11 billion dollars by PTI they stand at 15 billion dollars.
4. GDP
When PML N took over from PPP in 2008 Pakistan’s GDP was 3.7 %. After 5 years effort PML N government picked it upto 5.8 %
Now IMF has projected GDP to be 2.9 % in 2019, 2.7 % in 2020 and by 2023 it would barely reach 4 %
5. Lastly, FDI
Increase of FDI by 20 % in a given month does not cover up the complete picture.
Total foreign investments have decreased by a whooping 77 % since PTI has taken over reigns.
