How to choose a parking account

  • Preferential limit: "3% a year" often applies only up to ₩5M. Compare by the effective rate on your own balance.
  • Interest payout frequency: daily or monthly payouts add a little compounding.
  • Deposit insurance: bank and savings bank deposits are protected up to ₩100M per person per institution (from September 2025). CMAs may not be protected depending on type.
