How to get the best fixed-deposit return in Thailand
- Compare several banks - smaller and digital banks often pay more than the big high-street names.
- Ladder your deposits across different tenures so some matures regularly and you can reinvest at new rates.
- Check how often interest compounds; more frequent compounding grows the maturity value.
- Factor in tax on the interest, and compare against short-term government bills or bonds.
