I have heard a few stories about those times in the 70s and 80s where people were selling their properties and putting the money in the bank which was paying 20% interest.
A bitter lesson on the difference between the nominal Vs real value of money rapidly ensued.
When we transitioned to the euro it seemed most shops straight up converted from escudo to eurocent. So if something cost 50 escudos it would cost 50 cents. I was a teen at the time so I remember having to pay double for breakfast and arcade coinop games and people blaming the inflation for the doubled price of stuff. Yet the chart doesn't represent this. I know the price of electronics for example wasn't doubled so I wasn't expect a 100% inflation rate or anything, but I still feels it should've been higher than 4%.
If I estimate the 10-ish years of 20% +/- 3% that's around 7x which I can't imagine.
1 euro = 166 PTS, 6 euro ~ 1000 PTS, the basic banknote.
Guess what happened. Exactly. Bread costing 100 PTS began to cost... 166, 1 euro.
It did go up 66%… but it took more than 15 years: https://dialnet.unirioja.es/descarga/articulo/6407661.pdf
And, of course, bars.
On the other hand, inflation affected different products in different ways. I remember how in January 1st 2002 a small bag of Ruffles Jamón costed €0.15 in a kiosk and now it's around €0.50 (or even more) in same places (and now contains less product and more air), and I doubt any other product that are nearly 300% percent inflation since 2002 (outside homes sadly)
