Has already happened. Pakistan's biggest problems now and in the future, besides immediate cash needs:
1. Virtually no commercial loans for a long time. Only avenue will be IMF and bilateral like Saudi Arabia, UAE, China
2. Loss of business confidence. All the smaller exporters may demand advance payment before shipping to Pakistani importers
3. Loss of talent. 700,000 skilled workers left Pakistan in 2022. This will accelerate. In a few years, there won't be anyone to maintain a semblance of civilization like electricity grids, railroads, telecommunication infrastructure, water and wastewater systems etc., This is the situation Lebanon is in now. This is a dangerous place to be in. At this point, it not hard to descend down to Somalia or Sudan.
Trends indicate a loss of general confidence in the country, because of difficult economic conditions and political uncertainty.
