How this comparison works
Each currency's strength index starts at 100 and accumulates its daily change against 15 other major currencies (a geometric mean of pairwise exchange-rate moves), using European Central Bank reference rates and other official sources. The relative figures above divide CZK's index by PLN's, so they reflect the two currencies' performance against each other while accounting for the whole basket. The real variant additionally adjusts each currency for its domestic CPI inflation.
