The Fee Waiver That Wasn’t: MPF Conservative Funds Can Claw Back “Waived” Fees Within 12 Months

Every MPF scheme must offer a Conservative Fund, and it comes with a rule everyone quotes and almost nobody finishes reading: in any month the fund’s return does not beat the MPFA’s prescribed savings rate, the trustee may not charge administrative fees that month. It sounds like protection. The very next sentence on the MPFA’s website says the trustee may recoup the uncollected fees in any of the following 12 months when returns beat the prescribed savings rate. A waiver is not a waiver — it is bookkeeping. A deferral is not a discount — it is a billing schedule. This article does one thing: take the MPFA’s own words apart line by line, price “no fees charged” over 30 years of compounding, and lay out a fee discipline for choosing your “safe haven”.

X-ray: two sentences, one accounting mechanism

From the MPFA’s “Money Market Fund – MPF Conservative Fund” page, the “Subject to fee control” section, in full:

Administrative expenses can only be charged when the returns of an MPF conservative fund for a given month exceed the monthly prescribed savings rate (PSR) published by the MPFA.

If the returns of an MPF conservative fund exceed the PSR in any one of the following 12 months, trustees can recoup uncollected administrative expenses to the extent of the excess returns.

The first sentence is the protection you think you have; the second is how the protection gets settled. Line by line:

The simplest arithmetic. A conservative fund with a 1.0% FER accrues roughly 0.083% a month. One month it returns 0.0005%, below the PSR (0.0010% a month in 2026) — no fee that month, and 0.083% goes on the tab. Next month it returns 0.20%, beating the PSR by 0.199%; the trustee lawfully recoups the 0.083%. Two months, 0.1667% collected in full — not a cent less. The “waiver” merely moves the charge from “this month” to “next month”.

And the first threshold barely exists. The 2026 PSR is 0.0010% a month, about 0.012% annualised. Conservative funds’ ten-year annualised returns run 1.2–1.5% (mpf.hk fund database: BOC-Prudential 1.46%, market average around 1.30%, Principal 1.21%) — roughly 0.10–0.12% a month. Money-market monthly returns are extraordinarily smooth: triggering the waiver needs a single month at or below 0.001%. In a higher-for-longer world, the protection gate almost never opens — while the recoup right in the second sentence never closes.

X-ray (continued): the same “Conservative Fund”, a 40% fee gap

The waiver mechanism is identical for everyone; the fee rate is not. From trustees’ fund fact sheets (via the mpf.hk fund database):

Cheapest 0.77%, dearest 1.07% — the same statutory “low-risk” option, a fee gap of about 40%. Remember: these FERs already reflect waived months — meaning even after counting the “protection”, the dearest still costs 40% more. The waiver mechanism may make you feel you “saved” in no-fee months; it does not change this ranking.

The compounding toll: a 30-year bill for 0.31 percentage points

0.7678% (Hang Seng/Manulife) versus 1.0738% (AMTD Invesco): a 0.31pp gap. Illustrative calculation — HK$5,000 a month, 7% gross annual return, assumptions held constant:

• 10 years: the fee gap costs HK$13,680
• 20 years: HK$84,714
• 30 years: HK$299,262

Thirty years, HK$299,262 — about 87% of today’s average MPF balance per member (HK$343,242, MPF Ratings September data). Pick the wrong trustee for the same “safe haven”, and thirty years can erase nearly one full average balance.

Then the second toll: real returns. Ten-year nominal annualised returns of 1.2–1.5% against August 2026 underlying inflation of 1.9% (Census and Statistics Department) — a real return of roughly −0.6pp a year. The MPFA’s own words: “Even though an MPF conservative fund is considered a low-risk investment product, it is not principal-protected and the return may not beat inflation and may even be negative.” Losing to inflation, while administrative fees get collected anyway — sooner or later. That is the full picture of the “safe haven”.

The control group is more damning: the Default Investment Strategy fee cap is 0.85%, with DIS funds actually averaging about 0.77%. AMTD Invesco’s conservative fund at 1.07379%, Allianz Class B at 1.02656%, Fidelity at 0.97549% — several “conservative” funds charge more than the statutory cap for the “do-nothing” DIS. The low-risk label, at a price above the lazy-fund ceiling.

The playbook: choose the “safe haven” like the fee product it is

Rule 1: a waiver is not a waiver — it is deferred bookkeeping. Do not park cash in a conservative fund for years because “they don’t charge in bad months”. The waiver will not save you a cent over 30 years — it only decides which month you pay.

Rule 2: check the FER, not the “waiver”. Thirteen funds above; the waiver changes none of the ranking. Look up your own scheme’s conservative fund FER on the MPFA fund platform or mpf.hk — a 0.31pp gap is HK$299,262 over thirty years.

Rule 3: use the ECA once a year — move the employee mandatory contributions. Employees may transfer mandatory contributions to a cheaper scheme’s conservative fund (the 0.77% tier) once per calendar year. Transfers execute at T+1/T+2 forward prices with out-of-market risk — split large moves into batches and steer clear of FOMC weeks.

Rule 4: TVC balances can move in full, any time, no employer needed. Tax-deductible voluntary contributions are not bound by ECA limits and can be shifted wholesale to the market’s cheapest scheme — the shortest path around an expensive employer-scheme conservative fund (locked in until 65; weigh the liquidity cost yourself).

Rule 5: use 0.85% as the benchmark. Any “conservative” option charging above the DIS cap of 0.85% has to answer one question: is the word “low-risk” worth a price above the lazy fund’s statutory ceiling?

The MPFA never lied — the two sentences sit there in plain text, one on the waiver, one on the recoup. What misleads is our reading habit: we stop after the first sentence. “No fees charged” was never a discount. It was a billing schedule. What isn’t collected this month gets collected next month — or the month after — arrears and all.
