Thailand's other deposit system

Thailand’s Deposit Protection Agency is unusually direct about this: deposits in savings co-operatives, credit unions and co-operative federations are not covered by its scheme.

That matters because the Bank of Thailand’s monetary statistics recorded ฿1.613 trillion in deposits at savings co-operatives in September 2026. A passbook at one of them can look reassuringly like a bank passbook. The legal arrangement underneath is different.

The difference is not a verdict that a co-operative is unsafe. Nor does it make a co-operative an informal chae with a logo and a committee room. It tells us something narrower and important: the Deposit Protection Agency’s statutory payout is not what stands behind that balance.

A deposit does not make a bank

The Bank of Thailand places savings co-operatives and credit unions among Thailand’s deposit-taking corporations. It also describes their distinct model: people with a common bond contribute funds, which are used to support other members; members may receive interest, dividends or other benefits.

That common bond is not decorative. The Co-operatives Act allows a co-operative to receive savings or fixed deposits from members, other co-operatives and specified connected organisations, under its own rules approved by the Registrar of Co-operatives. This is not a general-purpose retail bank inviting the whole high street in for a promotional rate.

It also means that a member’s share and a member’s deposit should not be casually merged into one pot called “savings”. The Co-operative Promotion Department’s English guide describes shares as member capital which can earn a dividend, and deposits as current or fixed accounts. Its more recent data count member shares and deposits separately.

The distinction does not settle every right on exit, withdrawal or loss. Those details depend on the co-operative’s approved rules and the account’s terms. It does stop one lazy conclusion: ownership of a co-operative and being owed money by it are related, but they are not the same entry in the books.

The million-baht rule stops at the boundary

The Deposit Protection Agency currently describes protection of up to ฿1 million per depositor per financial institution for qualifying baht accounts. In the same FAQ, it lists deposits at co-operatives among the products not protected, and savings co-operatives, credit unions and co-operative federations among the institutions outside the Deposit Protection Act.

So the familiar bank calculation — add the qualifying accounts at one institution, then compare the result with ฿1 million — does not apply to a savings co-operative deposit. A member cannot make an uncovered balance covered by splitting it between a co-operative’s branches or product labels.

That is a boundary of this particular statutory fund. It does not mean that co-operatives operate without rules, audits, members’ meetings, assets, liabilities or legal obligations. Deposit insurance and supervision do different jobs. One promises a defined payout after a defined banking failure; the other tries to reduce the chance and severity of failure before that point. Neither phrase is a substitute for reading the relevant institution’s records.

What sits behind the passbook instead

Savings co-operatives are supervised under the Co-operatives Act, not the Financial Institutions Business Act that governs commercial banks. The Bank of Thailand identifies the Board of National Cooperative Development as their supervisor. The Co-operative Promotion Department publishes the practical machinery around that model: approved deposit rules, accounting controls, liquidity reporting and supervision standards.

Some of those standards are concrete. The Department says that all savings co-operatives and credit unions are subject to a 4% annual ceiling on deposit interest. It also says that larger institutions, with assets of at least ฿5 billion, must publish a monthly abbreviated asset-and-liability statement at their head office, branches and website.

The rules are not an insurance policy in another hat. A ministerial regulation on deposits and investment took effect on 27 November 2024. The Department says its purpose is to manage surplus liquidity at lower risk and to limit concentration, including a 10% cap on deposits or investments with a single juristic person in the specified cases.

That is evidence of active prudential rules, not proof that every balance sheet is equally strong or every rule is perfectly enforced. The National Economic and Social Development Council’s 2025 account of co-operative debt says important rules on lending, guarantees and data management were still incomplete, while the Department was supervising every type of co-operative. Its concern is principally borrower debt, but it is a useful warning against pretending that “supervised” ends the enquiry.

Big enough to be ordinary

Savings co-operatives are easiest to miss if you only look for shopfront banks. In 2024, the Co-operative Promotion Department counted 3.47 million members, ฿3.43 trillion in assets and ฿1.43 trillion in deposits across savings co-operatives. Its ten-year analysis says member loans were still the principal use of funds, although investment had grown to 22.3% of assets.

The Bank of Thailand’s September 2026 monetary series, a different and more current statistical frame, records ฿1.613 trillion in savings-co-operative deposits: ฿1.444 trillion in savings deposits and ฿169 billion in time deposits. The two releases should not be welded into an invented trend line. They use different dates and reporting frames. They do establish scale.

For balance, the Bank’s 2025 Financial Stability Review said the sector’s financial position remained sound in the third quarter of that year. It recorded ฿1.68 trillion in share capital and reserves, and noted that co-operatives’ senior claims on member salary deductions limited credit risk. That system-level judgement is the strongest reason not to turn this article into a siren.

It is still not a certificate for a particular co-operative. A sector can be sound while individual institutions have different loan books, liquidity, investment exposure, governance and terms. The same is true of banks, which is why deposit insurance exists in the first place.

The useful questions are smaller than “is it safe?”

For a particular account, the public record cannot deliver a universal answer. It can identify questions a member should ask of their own co-operative:

• Is the balance a share account, a deposit account, or both?
• What do the approved deposit rules say about interest, notice and withdrawal?
• What do the latest audited accounts and the annual members’ meeting disclose about assets, liabilities, loans, investments and reserves?
• If the co-operative has at least ฿5 billion in assets, where is its latest required monthly summary?
• Has anyone described this balance as Deposit Protection Agency-covered when the Agency’s own scope says otherwise?

This is a reporting checklist, not a recommendation to deposit, withdraw or retain money. The answer may differ between co-operatives and between account types at the same co-operative. A family deciding what to do with substantial savings should obtain qualified advice and the actual rules, rather than rely on a general article — however handsome the passbook.

A different promise

Thailand’s savings co-operatives are not hidden banks. They are a large member-finance system, with a different legal design, its own governance and a substantial supervisory framework.

The crucial fact is also the least theatrical one. A savings co-operative deposit is not inside the Deposit Protection Agency’s statutory scheme. In exchange, a member is relying on the co-operative’s assets, rules, management, oversight and collective governance. That can be a perfectly real structure. It is simply not the same promise as a protected bank deposit.

Common misconceptions

“A savings co-operative deposit is protected up to ฿1 million.” No. The Deposit Protection Agency explicitly excludes deposits at co-operatives. The ฿1 million limit is therefore not the relevant calculation.

“No DPA protection means the co-operative is unregulated.” No. Savings co-operatives are supervised under the Co-operatives Act and are subject to rules on matters including deposit rates, disclosures and investment. Supervision is different from statutory deposit insurance.

“Shares and deposits are the same thing.” Not necessarily. Co-operative records and guidance treat member share capital and deposits separately; the rights and terms should be checked in the co-operative’s own approved rules.

“A 4% deposit-rate ceiling guarantees the money.” No. A rate ceiling limits one term of a deposit product. It is not a guarantee of repayment or a measure of a particular co-operative’s condition.

“The sector is in collapse.” The Bank of Thailand described the sector’s financial position as sound in Q3 2025. That is a sector-level assessment, not a prediction or warranty for every co-operative.
