A plain-English guide to Astrea private equity bonds: how they work, what they pay, how to buy them, and how they stack up against T-bills, SSBs and fixed deposits.
At a glance
- What they are: retail bonds issued by Azalea, a company owned by Temasek, and backed by the cash flows of a diversified portfolio of private equity funds.
- Latest series: Astrea 9, issued in August 2025. The retail Class A-1 tranche pays a fixed 3.4% per annum in Singapore dollars, with a minimum investment of S$2,000.
- Tenor: a scheduled call at year five and a final maturity at year 15.
- Who they suit: investors who want a fixed, investment-grade coupon and understand that these bonds are not capital guaranteed and not government backed.
Astrea bonds are one of the most closely watched retail investments in Singapore. Each new series attracts strong demand, and the retail portion of Astrea 9 was increased by 37% over the previous series to meet interest from individual investors. The appeal is a fixed coupon from an unusual source: instead of lending to a single company or government, you buy bonds backed by a spread of private equity funds. This guide explains what Astrea bonds are, what they pay, how to buy them, whether they are safe, and how they compare with other low-risk options. If your wider goal is a steady payout, it also helps to understand the general case for building an income stream from bonds.
What are Astrea bonds?
Astrea bonds are retail bonds issued under the Astrea programme by Azalea. The issuer of each series is a dedicated company, such as Astrea 9 Pte. Ltd., which is an indirect subsidiary of Azalea Asset Management. Azalea is wholly owned, through Seviora Holdings, by Temasek. That Temasek link is part of why the bonds draw attention, but it is important to be precise: the bonds are issued by the Astrea entity, not by Temasek, and they do not carry a Temasek or Singapore Government guarantee.
What makes Astrea bonds unusual is where the money to pay you comes from. Most bonds are serviced by the earnings of one borrower. Astrea bonds are serviced by distributions from a large, diversified portfolio of private equity funds, an asset class normally reserved for institutions and the wealthy.
The programme has a track record. Astrea IV, launched in 2018, was the first Astrea series offered to retail investors in Singapore. It was followed by Astrea V (2019), Astrea VI (2021), Astrea 7 (2022), Astrea 8 (2024) and Astrea 9 (2025). Each series has offered a retail tranche, known as the Class A-1 bonds, denominated in Singapore dollars.
How Astrea bonds work
Behind each Astrea series sits a portfolio of private equity funds. Astrea 9, for example, is backed by 40 funds managed by 31 general partners, holding stakes in 1,086 underlying companies, with a total net asset value of about US$1.6 billion as of 31 December 2024. As those funds sell companies and return cash, the money flows up to the Astrea issuer and is used to pay bondholders and build reserves.
Because private equity cash flows are lumpy and uncertain, the Astrea structure wraps several safeguards around the retail bonds. Unlike actively managed bond funds, where a manager buys and sells holdings over time, the Astrea portfolio is largely fixed at launch and the protections are built into the deal:
- Reserves accounts. Cash is set aside over the life of the deal and accumulates to redeem the Class A bonds at their scheduled call date, rather than relying on a single payout at maturity.
- Bonus redemption premium. Class A-1 holders receive an extra payment of 0.5% of the principal if the bonds are redeemed on the scheduled call date and conditions are met.
- Sponsor sharing. Once a performance threshold is reached, half of the sponsor’s remaining cash flow is diverted into the reserves accounts until a cap is met, which speeds up the build-up of cash to repay bondholders.
- Maximum loan-to-value covenant. The structure must stay at or below a set loan-to-value level, and if it rises above that, fund cash flow is redirected to reserves instead of the sponsor.
- Credit facility. A standby facility is in place to cover expenses and interest payments if cash flow is temporarily short.
These features are why the retail tranches have carried investment-grade credit ratings. They reduce risk, but they do not remove it, which matters for the safety question below.
Current Astrea bond rates
The newest series sets the current benchmark. Astrea 9, issued on 8 August 2025, priced its retail Class A-1 bonds at a fixed 3.4% per annum in Singapore dollars. If the bonds are not redeemed on the scheduled call date in 2030, the coupon steps up once to 4.4% per annum. The series also included a US dollar Class A-2 tranche at 5.7% per annum (stepping up to 6.7%), with retail subscribers paying in Singapore dollars at a fixed rate of US1.00toS1.2852. A separate Class B tranche paying 7.35% was offered only to institutional and accredited investors, not to the retail public.
Coupons differ from series to series because each is priced to the interest-rate environment of its day. Here is how the retail Class A-1 rate has moved across the programme:
| Series | Year issued | Class A-1 coupon (SGD) | Status |
|---|---|---|---|
| Astrea IV | 2018 | 4.35% | Redeemed |
| Astrea V | 2019 | 3.85% | Redeemed |
| Astrea VI | 2021 | 3.00% | Redeemed (March 2026) |
| Astrea 7 | 2022 | 4.125% | Outstanding |
| Astrea 8 | 2024 | 4.35% | Outstanding |
| Astrea 9 | 2025 | 3.40% | Outstanding (latest) |
Coupons are fixed at issue and sourced from Azalea’s series releases and product pages; rates are per annum and carry a one-time step-up if not called on schedule. Figures as of November 2026.
Two points matter. The coupon is fixed for the life of the bond, so it does not rise if interest rates climb after you buy. And once a series has closed, you can no longer get the original coupon at issue; buying on the secondary market means paying the prevailing price, which changes the yield you actually earn.
Astrea bonds minimum investment and tenor
For Astrea 9, the retail Class A-1 bonds had a minimum subscription of S2,000andtradedinboardlotsofS1,000 after listing. Minimums on earlier series were similar, which keeps the bonds accessible to ordinary investors rather than only the wealthy.
The tenor has two dates that often confuse first-time buyers. The scheduled call date is when the issuer intends to redeem the bonds early, funded by the reserves it has built up. For Astrea 9 that date is 8 August 2030, roughly five years after issue. The final maturity date is the long-stop date if the bonds are not called earlier. For Astrea 9 that is 8 August 2040, giving a 15-year legal maturity. In practice, every retail Class A-1 tranche so far has been redeemed at or around its scheduled call date rather than running to final maturity, though that is a track record, not a promise.
Is Astrea bonds safe?
This is the most common question, and it deserves a straight answer. Astrea 9’s retail bonds carry investment-grade credit ratings: an expected A+sf on the Class A-1 tranche and Asf on the Class A-2 tranche, both from Fitch. The structural safeguards described above, together with the diversified portfolio, are what support those ratings. The programme’s record also helps: the Class A-1 bonds of Astrea IV, V and VI have all been redeemed on their scheduled call dates, and holders received the bonus redemption premium.
That said, “investment grade” is not the same as “risk free,” and Astrea bonds are not a savings product. They are not capital guaranteed, not government backed and not covered by the Singapore deposit insurance scheme. Unlike how Singapore Treasury bills work, which are backed by the full faith and credit of the Singapore Government, Astrea bonds depend on cash flows from private equity funds, and those cash flows can slow in a weak market. The main risks to weigh are:
- Private equity and valuation risk. If the underlying funds underperform or distributions dry up, the reserves that repay you build more slowly.
- Call-timing risk. The bonds may not be redeemed on the scheduled call date. If that happens you keep earning the stepped-up coupon, but your capital is tied up for longer.
- Currency risk. The Class A-2 tranche is in US dollars, so its value in Singapore dollars moves with the exchange rate. The Class A-1 retail tranche avoids this.
- Secondary-market price risk. If you sell before redemption, you take the market price, which can be below what you paid, especially if interest rates have risen.
How to buy Astrea bonds
There are two ways in, and which one applies depends on timing.
At launch (the public offer). When a new series opens, retail investors apply during a short subscription window, usually about a week. For Astrea 9 the public offer ran from 31 July to 6 August 2025, and applications were made through the lead banks’ ATMs and digital or internet banking channels (DBS, OCBC and Standard Chartered for that series), as well as the SGX IPO process. Demand is typically high, so you may be allocated less than you apply for.
After listing (the secondary market). Once a series lists on the SGX Mainboard, the bonds trade like any other listed security. You can buy or sell them through a brokerage account that offers SGX bond trading, at the prevailing market price, which may be above or below the original par value. Between issues there is no live public offer, so the secondary market is the only way to buy an existing series. If you miss a launch, there is no need to rush: a new series has historically come every 12 to 18 months.
Astrea bonds vs fixed deposits, T-bills and Savings Bonds
Astrea bonds sit between a bank deposit and a market investment. The table below shows the trade-offs at a glance:
| Feature | Astrea Class A-1 | Fixed deposit | Singapore T-bill | Singapore Savings Bond |
|---|---|---|---|---|
| Issuer / backing | Astrea (PE fund cash flows) | Bank | Singapore Government | Singapore Government |
| Capital guarantee | No | Yes, within SDIC limits | Yes, held to maturity | Yes |
| Typical tenor | 5 years to call | A few months to a few years | 6 months or 1 year | Up to 10 years, flexible exit |
| Liquidity | Sell on SGX at market price | Locked, with penalties | Sell early at market price | Redeem any month |
| Minimum | About S$2,000 | Often S500toS20,000 | S$1,000 | S$500 |
Fixed deposits and government securities win on certainty: your capital is protected and the outcome is known. Astrea bonds offer a higher fixed coupon in exchange for taking on credit and market risk. For a detailed look at the government options, see our guide to comparing SGS and Savings Bond yields. And if your priority is a fixed return on cash with no market exposure at all, a fixed, guaranteed cash option may suit better than a bond that can move in price.
Who Astrea bonds suit, and a hands-off alternative
Astrea bonds can make sense for an investor who wants a fixed, investment-grade coupon, is comfortable locking money up for around five years, and understands that the payout depends on private equity cash flows rather than a guarantee. They are less suitable if you need guaranteed capital, might need the money at short notice, or are uneasy holding a single bond series through a market cycle.
They also take effort: watching for each new issue, applying in the window, and deciding whether to buy on the secondary market in between. If you like the idea of regular bond income but would rather not manage individual issues, an income-focused portfolio spreads your money across many bonds and pays out regularly, without you bidding at each launch or picking single names. It is a different trade-off from a single Astrea series, but it answers the same goal of steady income.

Frequently Asked Questions
They carry investment-grade credit ratings and several structural safeguards, and every retail tranche so far has been redeemed on schedule. But they are not capital guaranteed, not government backed and not covered by deposit insurance, so they carry more risk than a fixed deposit or a Treasury bill.
For the most recent series, Astrea 9, the retail minimum was S2,000, trading in S1,000 board lots after listing. Earlier series used similar minimums.
If a new series is open, apply during the public offer through the lead banks’ ATMs and digital banking. Otherwise, buy an existing series on the SGX secondary market through a brokerage that offers bond trading, at the market price.
No. The coupon is fixed, but your capital is not guaranteed. Repayment depends on the cash flows of the underlying private equity funds.
Azalea has issued a new series roughly every 12 to 18 months, but there is no fixed schedule. Check Azalea’s announcements for the next launch.
No. T-bills, SGS bonds and Savings Bonds are backed by the Singapore Government. Astrea bonds are issued by a Temasek-owned company and backed by private equity cash flows, a different risk profile.
