How CZK lending actually works
Trade Republic and Revolut Ultra offer CZK-denominated savings yields that track the ČNB's deposit rate. Trade Republic specifically offers DGS-protected CZK deposits at policy-rate-tracking yields (currently the highest sustained CZK retail yield in Czechia). Bunq Premium offers tiered yield on CZK balances. Note that yield products on non-EUR currencies are limited at most EU neobanks — Revolut and Bunq are the main multi-currency yield providers.
Watchouts and hidden costs
Some EU neobanks present 'savings interest' that's actually a money-market fund pass-through, which is NOT covered by Garanční systém finančního trhu. Trade Republic specifically discloses whether each savings product is DGS-protected vs MMF-routed. Always check the deposit-protection footnote before parking material amounts of CZK above €100,000 (CZK equivalent).
