USD Time Deposit vs USD Lending: Rates, Protection, and Risks

A USD time deposit means keeping US dollars at a bank: the rate follows the bank's posted rate, and USD time deposits at domestic banks in Taiwan are covered by deposit insurance up to a limit. USD lending means lending US dollars to traders who use leverage on Bitfinex: the market rate moves with supply and demand and has swung widely over the past year, it is not covered by deposit insurance, and you take on exchange and borrower-side risks. Below, the two are compared side by side on rates, protection, liquidity, and risk.

Data as of 2026-10-20. Rates and rules change; the bank's rate board and Bitfinex's official announcements are the final word. The Bitfinex sign-up link above carries Kindo's referral code.

How do a USD time deposit and USD lending differ?

Comparison	USD time deposit	USD lending (Bitfinex)
Who you lend to	The bank	Traders using leverage on Bitfinex (borrowers must post collateral)
Rate	Follows the bank's posted rate	The market rate moves with supply and demand; it can be high or close to 0. A fixed-rate offer keeps its rate once matched; FRR-type offers keep changing after they are matched
Deposit insurance	Yes for deposits at domestic insured banks: up to NT$3 million per depositor per bank, NT dollar and foreign currency combined	No
Getting your money back early	You can terminate early, but the interest is reduced	Once lent, you wait for expiry or for the borrower to repay; you cannot recall it yourself
Term	By the bank's terms, e.g. 1 month to 1 year	2 to 120 days per offer (official explanation)
Costs	Currency exchange spread (Taiwan Cooperative Bank charges no extra fee when you deposit by converting NT dollars)	The platform takes a cut of the interest: 15% for regular offers, 18% for hidden offers (fee schedule)

What is the USD time deposit rate?

Posted annual USD time deposit rates at three banks:

Bank	1 month	3 months	6 months	1 year
Bank of Taiwan	2.00%	2.00%	2.00%	2.05%
Taiwan Cooperative Bank	2.00%	2.00%	2.05%	2.05%
Mega Bank	2.00%	2.00%	2.00%	2.05%

These are posted rates and do not include promotional rates that banks offer separately.

Two rules to know:

• Deposit insurance: according to the Central Deposit Insurance Corporation, foreign currency deposits are covered too. Each depositor's NT dollar and foreign currency deposits at the same domestic insured bank, principal plus interest, are covered up to NT$3 million in total, paid out in NT dollars. Deposits at offshore banking units (OBU) and at banks' overseas branches are not covered.
• Early termination: taking Taiwan Cooperative Bank's foreign currency time deposit rules as an example, no interest is paid if the deposit has been held for less than a month; after a month or more, interest is paid at 80% of the posted rate, as of the start date, for the term matching the time actually held, as simple interest. Rules differ by bank, so check with yours.

What is the USD lending rate?

Bitfinex lending rates are set by supply and demand between lenders and borrowers and change every day. Below are the 30-day USD borrowing rates over the past 12 months, calculated from Bitfinex's official public data (taking the last trade of each day) and annualized:

• It swings widely: about one in ten days was at or below 5.47%, and about one in ten at or above 15.25%. Monthly medians ranged from 6.02% to 13.70%.
• It can get close to 0: the lowest daily closing rate was just 0.19%, and trades close to 0 also happened intraday.
• The traded rate is not your return: this is the rate at which loans were matched in the market. Your actual return depends on the rate and term you set, how much of the time your funds are actually lent out (days without a loan earn nothing), and the platform's cut, so it will not necessarily equal this figure.

For how to read the rates and why they are sometimes especially high, see Why Bitfinex Lending Rates Are High. For a full introduction to USD lending, see What Is USD Lending.

What risks does USD lending carry that a time deposit doesn't?

• No deposit insurance: the Central Deposit Insurance Corporation states plainly that non-deposit products such as virtual assets are not covered. Funds held on an exchange have no deposit insurance to pay out if the exchange runs into trouble.
• Exchange risk: Bitfinex was hacked in 2016 and the loss was shared across all accounts. According to Bitfinex's announcement at the time, every account's assets were reduced by 36.067%, lenders included. For this and other public events, see Is Bitfinex Lending a Scam.
• Borrower-side risk: borrowers post collateral and are liquidated if they fall below maintenance margin. According to Bitfinex's official risk FAQ, if liquidation cannot keep up in extreme markets, losses may ultimately be shared by lenders.
• Rate risk: when the market is quiet, rates can be low, and your funds may not be lent out at all.
• Liquidity: according to Bitfinex's official explanation, once lent, the lender cannot recall the funds early; you wait for expiry or for the borrower to repay early — up to 120 days, depending on the term you set.

A risk both share: the exchange rate

If your money starts out in NT dollars, either option means converting to US dollars first, and when you convert back you may end up with fewer NT dollars because of exchange rate moves. Conversion also has a spread: using Bank of Taiwan's spot rate board as an example, buying US dollars with NT dollars and selling them straight back loses about 0.46%.

USD lending adds one more layer: to get US dollars onto Bitfinex, you first convert them into a dollar stablecoin such as USDT and transfer it in, or use an international wire. For what a USD stablecoin is and how it differs from a dollar deposit, see What Is a USD Stablecoin. With USDT, you also carry the risk that its price drifts from 1:1 with the dollar; see USDT vs USD Lending.

USD time deposit or USD lending: how do you choose?

Start with four questions:

• Does this money need deposit insurance? If so, USD lending is not a fit.
• Can you accept a rate that moves with the market? If you want to know the applicable rate when you deposit, a time deposit fits better.
• When will you need this money? A time deposit can be terminated early with reduced interest; a loan must run until expiry or until the borrower repays early.
• Can you bear exchange and borrower-side risk? Only lend idle funds you can afford to lose.

It doesn't have to be one or the other: some people keep the part that needs protection in a time deposit and lend out idle funds that can take the risk.
