> I'm not thinking about that. You're implying that stable means nominally equal from one year to another. So if a beer is 5$ in 2026, stability would mean it will keep being 5$ in 2027, then 5$ in 2030 and so on and so forth (at least if I get your argument right).
Correct.

How do you plan financially if prices are not stable.

They're an exception. Food, housing, transport, health are the things that matter. Just check your monthly budget.
