Five-year JGBs and Japanese bank fixed-term deposits are not interchangeable, and there is no universal winner. If you need a predictable rate and a clear early-exit rule, compare a retail five-year fixed-rate JGB with a specific deposit; if you are considering a marketable five-year JGB, account for the chance that its sale price will be below what you paid. As of November 2026, a five-year market benchmark yield and one bank’s posted deposit rate are different measures—not proof of which product will pay more.
| Name | Best for | Key spec | Rate / minimum | Checked |
|---|---|---|---|---|
| Marketable five-year JGB | Investors who understand bond pricing and can hold to maturity | Fixed coupon; market sale price can rise or fall before maturity | Five-year benchmark yield: 2.209% on November 12, 2026; not a guaranteed return on a purchase | November 2026 |
| Retail five-year fixed-rate JGB | Savers seeking a fixed five-year rate with defined early-redemption terms | Interest paid semiannually; generally redeemable after one year with a deduction | ¥10,000 minimum, in ¥10,000 units; use the current issue rate, which is not established in the figures below | November 2026 |
| Five-year fixed-term deposit at Japan Post Bank | Savers who want a bank deposit with a contracted term rate | Agreed rate generally applies through the term; early withdrawal may earn less | 1.100% annual rate before tax, effective November 9, 2026 | November 2026 |
What exactly are you comparing?
“Five-year JGB” can mean two different Japanese government bonds. A marketable five-year JGB is traded as a bond, with a price that can change. A retail five-year fixed-rate JGB is a separate product for individual investors, with its own rate-setting and redemption rules. Neither should be confused with a bank’s five-year fixed-term deposit.

The distinction matters because the headline numbers often cited for these products do not measure the same thing. A bond’s yield depends on its purchase price and the payments it generates; a deposit rate is the rate set in the deposit contract; and the retail bond’s rate is set under its own issue conditions. For a fair decision, start with the exact product and issue, not just the phrase “five-year rate.”
What do the latest figures actually show?
The dated figures provide context, but they do not establish a winner. JGB Information, displaying Ministry of Finance data, reported a 2.209% five-year benchmark yield on November 12, 2026, and an average yield of 2.186% for that day’s five-year JGB auction. Japan Post Bank’s five-year fixed-term deposit rate was 1.100% per year before tax, effective November 9, 2026.

The benchmark is a market measure for a marketable bond; the auction figure is an average yield for a particular issue. Neither is the coupon or offer rate on a retail five-year JGB. The Ministry of Finance determines the retail product’s offer rate through a separate formula linked to a five-year market yield, so check the relevant monthly issue conditions rather than substituting the benchmark. JGB Information’s benchmark and auction data and the Ministry of Finance retail JGB overview describe separate measures.
These values are snapshots from November 2026, not forecasts. Market yields can change, banks can revise rates offered on new deposits, and a deposit contract’s rate is not necessarily available to every customer or for every amount. The 1.100% figure is Japan Post Bank’s posted rate, not a ranking of Japanese banks. The bank’s rate list and its November rate announcement identify the applicable date and product.

A proper comparison needs the current retail JGB issue rate, the deposit’s exact terms, the amount and investment date, tax treatment, intended holding period, and likely access needs. The figures available here do not establish all of those inputs, so they do not support a precise after-tax return comparison.
How does a marketable five-year JGB work?
A marketable JGB is a bond that can be traded before its maturity date. Its coupon is set around issuance and remains fixed to maturity; interest is generally paid every six months, with principal paid at maturity. If held to maturity, the official Ministry of Finance description says the principal amount is paid. If sold earlier, however, the market price may be higher or lower than the original purchase price. The Ministry of Finance guide to JGBs explains both the maturity payment and the possibility of a different sale price.
That price risk is the central practical difference from a bank deposit. When market interest rates move, the value at which an existing fixed-coupon bond can be sold may move too. A quoted yield is not a promise that a particular buyer will earn that rate regardless of the purchase price or the time of sale. A holder who needs cash before maturity must check the current price and any transaction costs with the intermediary; the proceeds may be less than the amount invested.

For the 2026 fiscal year, the Ministry of Finance issuance plan groups five-year issues into quarterly reopening periods and notes that the schedule can change with market conditions. An issuance calendar is not enough to assess a particular purchase: identify the bond’s coupon, current price, yield, maturity date, and costs. See the FY2026 interest-bearing JGB issuance plan for schedule context.

How does the retail five-year fixed-rate JGB work?
The retail five-year fixed-rate JGB is designed for individual investors and is not the same security as a five-year marketable bond. Its rate is fixed for the issue’s five-year term, and it pays interest every six months. The minimum purchase is ¥10,000, in increments of ¥10,000. Interest is taxed at 20.315% when paid unless an eligible tax-exempt arrangement applies, according to the Ministry of Finance product terms.
Its access rule is more specific than “you can get your money back anytime.” In ordinary circumstances, redemption is generally available after one year. A deduction applies: an amount equivalent to the previous two pre-tax interest payments multiplied by 0.79685 is deducted from the redemption amount. The deduction means early redemption has a cost, even though it avoids selling the bond at a fluctuating market price. The Ministry of Finance also describes exceptions to the one-year waiting period in specified disaster and death circumstances; check its current product terms for eligibility and procedure.
Because the retail product’s rate is issue-specific, the benchmark yield in the table cannot fill in its missing offer rate. Before buying, check the monthly issue conditions for the rate, dates, and redemption terms that apply to the issue you can actually purchase. Do not assume the rate will equal the current five-year benchmark.
How does a five-year bank fixed-term deposit work?
A fixed-term deposit is governed by the bank’s contract. For Japan Post Bank, the listed five-year rate was 1.100% per year before tax from November 9, 2026. The bank says the agreed rate generally applies during the term, while an automatically renewed deposit receives the rate in effect at renewal. If a customer withdraws early, a lower rate may apply, so the contract’s premature-withdrawal rules matter as much as the advertised rate.

A term deposit can suit someone who prefers a bank deposit contract over a tradable security and is prepared to leave the money in place. But “deposit” does not mean that every account has identical terms, access, or protection. Confirm the institution, account type, minimum and maximum balance, interest calculation and payment schedule, renewal instructions, early-withdrawal rate, and applicable deposit-insurance status. The current coverage rules were not verified in the source material for this comparison, so do not assume a coverage amount or eligibility without checking the relevant official rules for the institution and account.
The bank’s rate is also not a market-wide Japanese deposit rate. Other banks may offer different terms, and a posted rate can change for new bookings. Check the rate applicable on the date you place the funds and keep the contract’s terms, rather than relying on a dated comparison article.
Which option is better if you may need the money early?
For money that may be needed before five years, compare the exit mechanism—not just the advertised rate. A marketable JGB can be sold, but its price may be below your purchase cost. A retail fixed-rate JGB generally allows redemption after one year, but the specified interest deduction reduces the amount you receive. A fixed-term deposit may permit early withdrawal under the bank’s terms, but it can pay a lower rate than the contracted one.
These are different forms of early-access risk. The marketable bond exposes the sale proceeds to market pricing. The retail JGB imposes a stated deduction under its redemption formula. The deposit may reduce interest under a contract-specific rule. If you have a known cash need before maturity, compare the likely date and amount of that need against each product’s actual exit terms; money needed on demand is a poor fit for a product whose early-exit cost you cannot accept.

How can you compare returns fairly?
Use the same starting date, principal amount, holding period, and tax assumptions for each option. For a marketable JGB, use the specific bond’s purchase price, coupon, maturity date, expected sale price if not held to maturity, and transaction costs. For a retail JGB, use the offer rate for the exact issue, the semiannual interest schedule, tax withholding, and the early-redemption deduction if relevant. For a deposit, use the rate and contract terms available for the exact account, the interest schedule, tax treatment, renewal choice, and any early-withdrawal reduction.
Then compare the outcomes that matter to you: total amount at maturity if held for the full term, cash received at the date you might need funds, and uncertainty around that amount. Use after-tax figures when comparing what you keep, while preserving the gross rate as context. Retail JGB interest is taxed at 20.315% when paid unless an eligible exemption applies; the deposit’s actual tax handling and the reader’s circumstances must be checked rather than assumed.
A useful worksheet is:
- Product and date: write the exact bond issue or deposit account and the rate’s effective date.
- Amount: use the same yen principal and note any minimum investment or denomination.
- Full-term result: calculate the cash flows to the same five-year endpoint using the product’s stated terms.
- Early-access result: estimate proceeds at the date you could need the money, including sale price, redemption deduction, or reduced deposit interest.
- Renewal and reinvestment: identify whether money is automatically reinvested and which rate would apply afterward.
- Risk and protection: distinguish market-price risk from contractual early-withdrawal terms and verify deposit-insurance eligibility.
This process avoids the false precision of comparing a market benchmark yield with a bank’s posted annual deposit rate as if both were guaranteed five-year outcomes.
Which option fits different cash goals?
Choose a marketable five-year JGB for consideration if you understand that the bond can be sold at a loss before maturity, can evaluate its price and yield, and expect to hold it to maturity or can tolerate price changes. Its marketability is useful, but that flexibility does not preserve principal at every sale date.
Consider a retail five-year fixed-rate JGB if a fixed rate for five years and a defined redemption option after one year are more important than unrestricted access. Compare the actual issue rate after tax and account for the early-redemption deduction. Do not use the marketable benchmark yield as a substitute for its offer rate.

Consider a five-year fixed-term deposit if you want a bank contract with a rate generally fixed for the booked term and can accept the provider’s early-withdrawal rules. Compare more than one institution if you want to know the available market range; Japan Post Bank’s 1.100% rate is one dated example, not a claim that it is the highest or best offer.
If the money is an emergency reserve or may be spent soon, the five-year headline rate should not decide the question on its own. A suitable choice depends on when you need access, how much fluctuation or penalty you can tolerate, and whether the product’s exact terms match your plan.

- Name the product precisely. Confirm whether you are buying a marketable five-year JGB, a retail five-year fixed-rate JGB, or a five-year deposit. A broad label can conceal important differences.
- Check the current rate or price on the decision date. For marketable bonds, obtain the particular issue’s price, coupon, yield, maturity, and transaction costs. For retail JGBs, read the current monthly issue conditions. For deposits, confirm the bank’s rate for the specific term and booking date.
- Read the exit terms. Write down when early sale or redemption is available and how the amount you receive may differ from the original principal or expected interest.
- Confirm tax and protection. Check whether an exemption applies to you, how the product handles tax, and—if using a deposit—whether the institution and account qualify for current deposit-insurance protection.
- Review what happens at maturity. Find out whether the funds are paid out or automatically renewed, and what rate and instructions apply after the original term.
The best comparison is the one tied to the exact issue or contract you can purchase, not a generic five-year rate chart. Official terms and rates can change; revisit the relevant Ministry of Finance or bank page before acting.
Frequently Asked Questions
Does a five-year rate protect my cash from inflation?
No nominal rate guarantees that your money will retain its purchasing power. Inflation can rise faster than the interest earned, so the outcome depends on inflation over your actual holding period as well as the product’s after-tax return.
Can I use a retail five-year JGB for monthly income?
It pays interest semiannually, not monthly. If you need regular monthly cash flow, compare the payment schedule with your budget before buying rather than treating the annual rate as monthly income.
Can I buy a retail JGB in a tax-exempt account?
The Ministry of Finance terms recognize eligible tax-exempt arrangements, but eligibility and account rules depend on the investor and account. Confirm the current conditions with the official product information and the institution handling the purchase.
Does a fixed-rate deposit keep the same rate after it matures?
Not necessarily. If a deposit automatically renews, Japan Post Bank says the renewal uses the rate in effect at that time, which can differ from the rate on the original deposit.
