How CHF investing actually works
Trade Republic settles CHF-denominated ETFs and equities at competitive FX rates (typically 0.15–0.25% spread) — its brokerage is the most institutionally serious among EU neobanks. Revolut's brokerage charges FX at the user's tier rate (free within allowance, 0.5% above) plus a per-trade fee. Bunq integrates with select brokers but operates more as a multi-currency wallet than a settlement layer for CHF assets. For larger CHF investing, the all-in cost (FX + per-trade fee + settlement spread) matters more than the headline trade commission.
Watchouts and hidden costs
FX cost on CHF-asset trades adds up: a 0.5% FX spread on a €10,000 trade is €50 you didn't see in the trade confirmation. Always verify the executed FX rate against mid-market. Tax: dividends from CHF-denominated assets may incur withholding tax in Switzerland, which is partially or fully recoverable via the EU's double-taxation treaties — check the relevant treaty for your residence country.
