Pros and cons

Pros

  • Funds are available on demand and withdrawals carry no fees, and the account is listed as easy access.
  • Personal loans of TOP 15,000 at an APR of 8% to 13% can be funded the same day once documents are complete.
  • Mortgages cover purchase, buy to let and remortgage at an initial rate of 8% with a 90% maximum loan to value.
  • Support runs on email, phone and community, so phone and email both reach the bank alongside community desks.

Cons

  • The account pays a headline rate of 1%, behind 3.29% at Wise and 3.01% at bunq, and a dormancy fee follows a long period of inactivity.
  • A monthly fee of TOP 1 applies to the passbook account, and opening it needs a minimum deposit of TOP 10.
  • Lending runs a hard credit check, wants good credit plus collateral, and settles a setup charge in cash before funds are released.

Who it suits

  • Adults resident in Tonga who want a passbook account with on-demand withdrawals and no withdrawal fees.

  • Homebuyers and landlords weighing a mortgage for purchase, buy-to-let or remortgage, with 90% maximum loan to value.

Who should look elsewhere

  • Savers chasing the top rate: Wise lists 3.29% and bunq 3.01%, both ahead of what this passbook account pays.
  • Readers who want a set term rather than a variable rate, where Finteres publishes 0% to 36%.

Frequently asked questions

What rate does the Tonga Development Bank passbook account pay?+

The passbook account pays a headline rate of 1% that is variable, so it can move with the bank. The minimum deposit to open it is TOP 10, and the account is listed as easy access.

What does it cost to keep the account open?+

Keeping the passbook account open costs a monthly fee of TOP 1, and opening it needs a minimum deposit of TOP 10. Loans carry their own charge, with a setup amount settled in cash before the money is released, so that cost sits outside the repayment.

Can I get my money out whenever I want?+

Yes on access: the account is listed as easy access, and the published terms say funds are available on demand with no withdrawal fees. Watch the balance, since the bank pays no return on amounts under its stated minimum, so a small sum sitting there earns nothing.

What happens if I leave the account untouched?+

The published terms charge a dormancy fee each month after a long period without activity, which can eat into a balance paying only 1%. Anyone holding a modest sum is better off moving money in and out, or closing the passbook account, rather than letting it sit.

Is the bank regulated, and is my deposit protected?+

Tonga Development Bank is a statutory bank operating in Tonga (TO) under the Tonga Development Bank Act 1977. It has traded since 1977. Ask the bank what cover applies to your balance before depositing a large lump sum.

Can I borrow from the bank as well as save?+

Yes. The bank is a direct lender and covers personal, secured and car loans. Personal loans run to TOP 15,000 at an APR of 8% to 13% across terms of 12 to 36, and the stated funding time is the same day once the paperwork is complete.

What credit do I need for a loan?+

The bank runs a hard credit check and asks for good credit, plus sufficient collateral, so borrowers with a thin credit file will struggle. Personal loans normally go to existing bank clients, with security valued above the amount borrowed.

How do I get help, and who can open an account?+

Support runs on email, phone and community, so phone and email are both available, alongside community desks. Accounts are for residents of Tonga (TO), with a minimum age to qualify, and personal lending is aimed at existing clients.
