Despite Ships permission to Pakistanis, Petrol and Gas problems still exist?

I want to understand how it works. On one hand, media, politicians are saying that Pakistani ships are allowed and even others ships are allowed in strait of hormuz if Pakistani flag is there but not only the petrol prices haven't come down, the LNG cylinder prices have skyrocketed and my fear is that they won't come down as significantly as is the norm in Pakistan - price ooper jaati hai hamesha, neechay nahi ati...So, what gives?
