The PTI has borrowed more than $26.2 Billion USD since they took office in August 2018 and took the most loans of any government in a single year within the history of Pakistan borrowing approximately $16 Billion USD in their first year in office.
In FY20: Govt gets over $13b in foreign loans
At that rate Khan and the PTI will borrow over $50 Billion USD during their 5 year term well over the $38 Billion you've stated the PML-N did.
Mind you this is the guy who told us that he'd commit suicide before taking a loan from the IMF:
Then what's the difference between the PML-N, PPP and PTI?
People supported, and voted, for Khan based on his stances particularly since 2010. However he himself admits that he’s gone back on his promises and it's ok because it doesn't compromise on his "ideology".
Nothing wrong with U-turns if they don’t ‘compromise ideology’: PM
Is it an ideology of lies, manipulation and ineptitude like what was practiced by previous governments?
There are a lot of things that Khan and the PTI have done and will do that is NOT what the large majority supported or voted him in for, he can't control a treasonous anti-Pakistan judicial system infiltrated by PML-N and PPP loyalists and people are so desperate for good Muslim leadership and so deep into this mess now they’ve convinced themselves that the PTI is something they aren’t.
Why wouldn't an increase in international crude oil prices have an impact on local prices if the rupee was "capped at a fixed price"? The rupee was never fixed to the price of crude oil.
Even after you adjust for inflation what Khan demanded in 2015 equates to about Rs. 89/liter today whereas Khan has raised fuel prices to well over Rs. 100/liter now.
So what happened to the poor peoples of Pakistan that he was pleading on behalf of and campaigning for in 2015-2016 who would be overburdened by these price hikes?
There's no excuse here, Khan either lied and manipulated the public to get votes or he was simply clueless about Pakistan's economic realities which is even more frightening considering he had spent years running for PM and should have educated himself on this.
This isn't the only time he's done something like this.
For example in 2016 when Nawaz Sharif and the PML-N wanted to privatize the PIA due to the losses they were incurring it was Khan and the PTI that came out in support of protesting PIA employees desperate to keep their jobs, put food on their tables and what does Khan do now? Lays off almost 50% of its staff centralizing its office in Islamabad:
Imran Khan visits Karachi to join protesting PIA employees
PTI protesters against PIA privatisation face traders’ wrath
PIA to completely shift to Islamabad by June
He's not privatizing the airline but that's just semantics because what he's doing is pretty much what privatizing the PIA would have done anyways and what people, including PTI loyalists, were protesting against back in 2016.
So Why did the PTI never suggest a restructuring of the PIA when the PML-N were in power instead of protesting any attempts at making changes?
How much has he and his party lied about?
In terms of foreign exchange reserves Khan was in a significantly better position than Nawaz Sharif and the PML-N were when they began their government in 2013.
Just look at the SBP's own official publication regarding this:
SBP | Foreign Exchange Reserves Archive
Total liquid foreign exchange reserves in the country as of September 13, 2013 (when Zardari's term officially expired) was approximately $10.3 Billion USD by the time Nawaz Sharif was convicted and removed from office on July 28, 2017 it had risen to $20.2 Billion USD.
The country's total liquid FX reserves doubled under Nawaz Sharif by the time he was convicted of corruption in relation to the Avenfield case.
When Khan and the PTI took office, after the PML-N interim government lead by Shahid Khaqan Abbasi finished, the total liquid foreign exchange reserves in the country had dropped to $16.7 Billion USD but they were still 60% larger (inflation only accounted for a mere 5.2% of that growth) than what Nawaz Sharif and the PML-N started with in 2013.
So why are Khan and others going on about depleted foreign exchange reserves?
The PML-N did make HUGE mistakes one of them was their refusal to devalue the rupee which only widened the trade deficit by making exports less competitive and imports cheap while limiting foreign investments.
I suspect this was done to control inflation much like how Khan and the PTI government are going on an import spree of food stuffs after having lowered the nations interest rates, that were raised to reduce inflation rates, to help pay down debts he's accrued and make debts he's looking to take easier to manage:
Food-Choked Ports Are a Drag on Pakistan’s Exporters
Food import bill surges by whopping 52.16pc to $3.91b in six months
No let-up in food price hike despite massive imports
Personally I am more of a fan of Khan's approach particularly because those high interest rates, itself a sin, prevented people from taking loans to buy homes limiting new home construction that affects a host of related industries and made it difficult for businesses to borrow to expand or entrepreneurs from starting new businesses.
