Hong Kong school debentures explained: the million-dollar seat

The short version

The short version

A debenture is a large capital payment to a school — historically an interest-free loan — that buys admissions priority, sometimes waives an annual levy, and may or may not ever come back. At most Hong Kong schools it is optional. Plenty of children enter every school on this list without one. What a debenture never buys, at any school that will say so in writing, is a guaranteed place.

The decision is arithmetic, not status. Compare the annual capital levy you would otherwise pay (sunk money) against the debenture’s depreciation, transfer friction and opportunity cost over your likely years in Hong Kong. For a three-year posting, levies usually win. For a ten-year stay with two children, a refundable instrument often wins. The worst outcomes come from buying depreciating instruments without reading the schedule — several Hong Kong instruments are designed to reach zero while you hold them.

The instrument

What debentures are, and why Hong Kong has them

Hong Kong’s international schools were built largely without government capital. Tuition covers running costs; it rarely covers land, buildings and expansion. Schools raised that capital the Hong Kong way: from parents and employers, upfront, interest-free, in exchange for queue priority. The debenture is the receipt for that loan. Capital certificates, foundation certificates, capital notes and nomination rights are cousins of the same idea with different fine print — and the name tells you almost nothing. Read the terms, not the label↗.

The market is no longer the Wild West. After a 2020 Ombudsman finding that the Education Bureau had been treating debentures as private arrangements its own rules did not support, EDB Circular 15/2023 brought the whole apparatus inside regulation: schools need EDB approval for debentures, capital levies and nomination-right fees, applied for at least six months before collection, with approvals typically running six school years, advance parent consultation and annual reporting on how the money was used. Parents buying today have more disclosure rights than the generation that funded the campuses↗.

The taxonomy

The taxonomy: who holds it, and what happens to the money

Two axes sort every instrument in the city. The first is who holds it: individual or family debentures nominate one child (or siblings), while corporate debentures are owned by an employer and can usually be re-nominated to another employee’s child when the first leaves — the classic expat-package perk, and a real negotiating point if your employer holds a pool of them.

The second axis is what happens to your capital, and this is where the money is lost or kept:

• Refundable at par: returned in full when the child leaves or after a holding period (GSIS’s standard HK$800,000 debenture; Kellett’s HK$120,000 individual). Your real cost is the opportunity cost of the capital.
• Redeemable on a schedule: returned only after a minimum hold — HKIS’s debentures redeem at par only after 15 years, which outlasts almost every expat posting.
• Depreciating: the refund shrinks on a schedule — Stamford American’s individual debenture reduces over eight years.
• Zeroing: designed to reach nothing — CIS’s HK$15 million Corporate Nomination Right depreciates to zero over five years; Shrewsbury’s HK$200,000–300,000 certificates zero over four. These are prepayment of priority, not loans.
• Non-refundable from day one: ESF’s HK$500,000 Individual Nomination Right buys interview priority and is simply gone.

And the structurally different cousin: the annual capital levy, a recurring non-refundable charge (HK$24,500–60,000 a year at the premium end) that many schools charge alongside debentures. Some debentures waive the levy; some famously do not. Many schools now charge both — the levy is the trend, because it converts one big reluctant payment into an easy recurring one.

The market

Real numbers by school

HKIS. Three debentures, direct from the school only: Family HK$3,000,000 (covers siblings), Standard Corporate HK$3,000,000 (one child), Comprehensive Corporate HK$5,000,000. HKIS’s own page is unusually clear: debentures are not mandatory, do not guarantee admission, place qualified applicants at the top of the wait pool, and cannot be sold — there is no secondary market. Redemption is at par after a minimum 15-year hold, and debenture applications for the next school year close 1 November. The HK$24,500 annual capital levy is charged separately; sources disagree on whether debenture holders are exempt from it — confirm with admissions in writing before you rely on either answer↗. One warning for your research: the “HK$6.5M direct, ~HK$4.3M secondary” Capital Note you will see quoted online belongs to ISF Academy, not HKIS — the two are routinely confused.

The ISF Academy. The Capital Note is HK$6,500,000 direct, but actively traded — roughly HK$4,300,000 on the secondary market, a structural discount that tells you demand has softened since the notes were issued. The note is non-refundable but transferable one year after issuance, waives the HK$40,000 annual capital levy, and confers top-tier priority including a second-chance assessment↗↗.

Chinese International School. The HK$15,000,000 Corporate Nomination Right is the city’s most expensive priority instrument — non-refundable and depreciating to zero over five years, which makes it a HK$3-million-a-year queue payment in economic substance. CIS also posts the city’s highest tuition: HK$300,300 primary and HK$359,200 senior years in 2026/27.

Kellett. The big 2025 story: from September 2025, Kellett abolished its mandatory debenture and moved to a HK$40,000 annual capital levy for all new students — a structural signal that upfront parental capital got harder to raise. The legacy ladder still exists for those who want priority: a HK$20,000,000 Golden Jubilee Debenture (non-redeemable, up to three children), a HK$10,000,000 Foundation Debenture (15-year life, redeemable at par), a HK$1,000,000 Corporate Debenture (eight-year life) and a HK$120,000 refundable individual debenture that carries no priority over corporate holders or siblings↗↗.

Harrow. No new instruments are being issued: the original HK$600,000 individual debentures sold out in 2012 and Capital Certificates (~HK$3–3.3 million) trade only through school-administered transfers. A certificate waives the HK$60,000 annual levy. The fine print is the best in the city as a warning example: transfers for 2027/28 nomination priority closed 10 October 2026, and the refund provision applies only to original direct subscribers — buy a certificate second-hand and the refund right does not come with it↗.

The rest of the map. GSIS: HK$800,000 refundable standard debenture, up to HK$6,000,000 for first-priority infrastructure debentures. CDNIS: no new issues; secondary-market Capital debentures around HK$2.2–2.8 million and Gold Corporate at HK$10 million, transfers administered by the school, levy HK$43,000. Shrewsbury: HK$200,000–300,000 certificates that waive the levy but zero over four years. French International: HK$120,000 private (refundable) / HK$250,000 corporate. Singapore International: compulsory personal debenture HK$200,000 (HK$120,000 for Singapore passport holders) plus HK$20,000 annual levy — one of the few schools where a debenture is genuinely mandatory↗↗.

The outlier

ESF: no debentures, and a subsidy going to zero

The English Schools Foundation — 22-plus schools, around 17,600 students — is the counterexample that proves the rule: the largest English-medium operator in the city requires no debenture at all. Its capital charge is a one-off non-refundable levy sliding from HK$38,000 at Year 1 down to HK$3,800 at Year 13, and its priority product is the HK$500,000 Individual Nomination Right — non-refundable, buying interview and waitlist priority only.

The reason to watch ESF is its funding cliff. The government’s recurrent subvention — HK$249.7 million a year in 2012/13 — is being phased out over 13 years from 2016/17 to 2028/29, at an average of HK$19.2 million a year, per the Legislative Council record. By 2023/24 the subvention was just 5% of ESF operating income against 80% from tuition. The 2013 terms protected already-enrolled cohorts from subvention-driven fee rises, but new families pay the new reality: secondary tuition is HK$181,100 in 2025/26 and HK$188,300 in 2026/27, and the phase-out completes in 2028/29↗. ESF remains the value anchor of the system — but “subsidised” now describes its history more than its future.

Priority vs guarantee

Does a debenture guarantee entry?

No — and the schools that sell them say so in writing. HKIS: debentures “do not guarantee admission”; holders go “to the top of the wait pool,” and all applicants must still meet admissions requirements. ESF’s nomination right buys priority for an interview, not an outcome. What priority means in practice scales with the price: at the top end (ISF’s note, GSIS’s infrastructure debenture) it includes privileges like a second-chance assessment; at the entry end (Kellett’s HK$120,000 individual) it can mean effectively nothing — that instrument explicitly carries no priority over corporate holders or siblings.

The honest mental model: a debenture buys you a better position in a queue whose length you cannot see. In a soft market — and the Kellett levy switch plus the ISF secondary-market discount both suggest 2026 is softer than the 2010s — plain applications succeed at schools that once needed instruments. Ask the admissions office directly: for our year group, how did last year’s non-debenture applicants fare? A straight answer is worth more than the brochure.

The secondary market

Buying on the secondary market

Where resale is allowed — ISF, Harrow, VSA, CDNIS among them — it is not a free market. Transfers are administered by the school, which charges transfer fees, controls timing (Harrow’s 10 October deadline for next-year priority) and can void the exercise if paperwork is late. Specialist brokers exist to match buyers and sellers; treat their quoted prices as indications, not a ticker.

Three structural risks before you wire anything. First, rights decay on transfer: Harrow’s refund provision dies when a certificate changes hands, so a “cheaper” second-hand instrument may be a strictly worse one. Second, you are pricing an illiquid asset: the ISF note’s HK$4.3 million secondary price against HK$6.5 million direct means sellers ate a third of face value — if your posting ends early, that discount becomes yours. Third, zeroing instruments have no floor: a CIS CNR bought part-way through its five-year life is a claim on a shrinking refund. Always get the school’s written confirmation of what transfers, what does not, and what the redemption schedule looks like from your purchase date.

The math

Buy vs levy: a break-even example

Take Harrow, the cleanest case. Without a certificate you pay the HK$60,000 annual levy — sunk money. With a secondary-market Capital Certificate at roughly HK$3.3 million, the levy is waived. Now run the comparison for a one-child family:

• Stay 4 years (typical posting): levies cost HK$240,000, gone. The certificate costs the opportunity cost of HK$3.3M — at a 4% risk-free return, about HK$528,000 over four years — plus transfer fees, plus resale risk in an illiquid market. The levy wins.
• Stay 8 years with the certificate holding value: levies cost HK$480,000; opportunity cost about HK$1.06M. The levy still wins on these numbers — the certificate only wins if you can resell at a premium, or if the levy rises steeply.

The lesson generalizes: when the debenture is a genuine loan (refundable at par), the comparison is levy-versus-opportunity-cost, and levies are usually cheaper than they look. The buy case flips when three conditions stack: a long stay, multiple children covered by one instrument, and priority that actually matters for your year group. Run the same math at HKIS (HK$24,500 levy, 15-year redemption — effectively a donation for most expats) and at Shrewsbury (a HK$250,000 certificate that zeroes in four years against HK$200,000 of levies over the same period — the certificate is only worth it for the priority, never the money). If the school will not give you the redemption schedule in writing, that is your answer.

The exit

Expiry and refund traps on departure

The debenture that felt optional on arrival becomes urgent on departure, and the traps all trigger at exit:

• Notice windows. Refunds typically require formal notice and follow the school’s schedule, not yours — some schools process redemptions once a year. Miss the window and your capital waits in Hong Kong after you have left.
• Holding periods that outlive postings. HKIS’s 15-year minimum means a redeemable-at-par promise dated 2041 for money paid today. Model it as such in your decision.
• Depreciation clocks that keep running. Zeroing instruments (CIS five years, Shrewsbury four) do not pause because your child leaves early — the refund is whatever the schedule says on exit day.
• Transfer rights that do not travel. Harrow’s refund right stays with the original subscriber; CDNIS transfers must run through the school; HKIS debentures cannot be sold at all. If your exit plan is “I’ll just sell it,” verify that selling is possible before buying.
• Deductions. Outstanding fees, damage charges and administrative fees come off the refund first.

The discipline: on day one, diarize the redemption rules for your departure year. Twelve months before leaving, write to the school asking for the exact redemption or transfer procedure, the deadline, and the expected payment date. Treat it like repatriating a pension, not returning a library book.
