Inflation is general. It’s in every country on earth. Unless the country doesn’t use fiat (which isn’t possible because what then are you using as legal tender).
That's true that it's in general there but it differs per country based on the economic status of their state.
In the next couple of years, the cost of petrol would likely be more than that. And even if it isn’t, other items like food items, or clothes would cost more. How you’d know this is when you look back to how it used to be, you can see the trend of inflation.
While there were even talks about electric cars(EV) and the reduction of the use of petrol will be there. I don't think that's gonna happen 100%.
There are still a lot of people that just want to stick to what we used to have and that will still make petrol's cost that high. And when petrol's cost is too high, everything will continue to rise in prices.
