A bank's or card issuer's quoted EUR/TRY rate differs from the mid-market rate shown here for two reasons — their own spread, and the fact that both sides of this cross are floating, so the reference rate itself can move noticeably between checking it and completing a transaction.

Banks and exchange counters typically build in a spread of several percent above the mid-market rate on this cross, and that spread can widen further during periods when eurozone and Turkish monetary policy are moving in sharply different directions.

Card networks apply their own daily conversion rate, and card issuers often add a separate foreign transaction fee on top — commonly one to three percent — so a card purchase in lira rarely lands exactly on the mid-market EUR/TRY figure shown here.

For remittances sent from Europe to Turkey, comparing a transfer service's quoted rate against this reference rate right before sending matters more than for a pegged pair, since the lira's volatility means a rate checked even a few hours earlier may no longer hold.

The rate shown here is a frequently updated mid-market reference rate — because both the euro and the lira float independently, treat it as a benchmark for comparison rather than a rate you can lock in ahead of time.
