Your account balance may rise when interest is added, but that number alone does not tell you whether the account suits your goals. Before deciding to keep a deposit, move accounts, or invest some of the money, consider interest, purchasing power, protection limits, and product risk separately.
The source video invites viewers to think about the limits of deposits and the effects of inflation. This article organizes the ideas into four checks and uses information from the Bank of Thailand and the Deposit Protection Agency (DPA) for current conditions.
1. An interest rate is quoted per year, not as the amount you receive each month
Read a quoted rate together with the account type, balance used to calculate interest, deposit period, withdrawal rules, and payment method. A readily accessible savings account and a fixed-term deposit may have different rates and conditions. Do not compare only the headline number. If you may need part of the money soon, early-withdrawal rules also matter.
The Bank of Thailand explains deposit interest formats and conditions and publishes historical commercial-bank deposit interest rates. For an account you hold, also read the rate announcement and terms from the bank directly.
2. The same balance does not always buy the same amount
Interest increases the numerical balance, while inflation changes the general prices of goods and services. If net interest over a period is lower than the increase in prices, the money's purchasing power may fall. The actual result depends on the period, tax, account terms, and each person's spending basket. This does not mean every deposit loses money or every investment beats inflation.
Instead of deciding from a headline, ask: When will I need this money? How readily must I be able to withdraw it? How does the expected return after costs fit the time I can hold it? Money for near-term expenses has different liquidity needs from money set aside for a long-term goal.
3. Deposit protection is calculated per depositor and financial institution
The DPA states a protection limit of up to 1 million baht per depositor, per financial institution, not 1 million baht per account. If you have several accounts at one institution, eligible principal and interest are combined. Protection applies only to eligible deposits and institutions covered by law, so check the official information before assuming a product is protected.
See the DPA's deposit protection limit and frequently asked questions. If your total is above the limit, do not assume that the excess automatically disappears or will be repaid immediately in full; repayment and liquidation follow the legal process.
4. Deposits and mutual funds serve different purposes and carry different risks
Moving money from an account into an investment does not increase the deposit's interest; it changes the type of risk. Investments may rise or fall in value, and you may lose money. Mutual funds are not deposits protected like bank accounts. Start with your goal, how long you can tolerate fluctuations, and when you may need the money, rather than reacting only to a low deposit rate.
If you are considering a fund, read its prospectus and Fund Fact Sheet for its policy, risks, investments, and costs. The SEC provides a guide to understanding a Fund Fact Sheet and a tool to find fund prospectuses and reports.
A checklist before deciding
- Separate money you need soon, emergency reserves, and money for longer-term goals.
- Compare interest rates with balances, withdrawal terms, and relevant taxes.
- Check the deposit protection limit and product eligibility with the DPA.
- If you move to an investment, review its risks and costs; past returns do not guarantee future performance.
The aim is not to choose one type of product for everyone. Each portion of money should fit when it will be needed and the level of risk its owner can accept.
