Sizing the exposure honestly
Most expat families underestimate their currency exposure on school fees because they think in nominal terms. A British family in Singapore paying SGD 50,000 per term per child does not see the underlying GBP cost shift each term. Yet between February 2022 and October 2023, GBP against SGD moved 11 per cent. On a SGD 200,000 annual fee bill for two children, that move was the equivalent of GBP 22,000 in unbudgeted cost over the period.
The first step in managing the risk is sizing it. Take the annual fee bill in the invoice currency, multiply by the number of years your child will be enrolled, and convert that total to the currency you actually earn in. That is the gross exposure. A 10 per cent currency move on five years of fees is, by definition, half a year of fees. The number is not small.
Three families of fee-currency profile
Expat families fall into one of three currency profiles, and the right hedge differs for each.
The first is the natural-hedge family: salary in the same currency as the fee invoice. A US family in Singapore paid in USD will find SGD-USD relatively stable due to MAS policy. A British family in London paid in GBP and paying GBP school fees has no currency risk on the fee bill itself. This is the simplest position and rarely needs active management.
The second is the partial-hedge family: salary in a major currency, fees invoiced in a peg or pseudo-peg. The classic example is a USD-paid family in Hong Kong (HKD pegged to USD) or a CHF-paid family in Geneva (CHF correlated with EUR). The peg or correlation does not eliminate risk, but it limits range to roughly 3 to 5 per cent over multi-year horizons.
The third is the open-exposure family: salary in one major currency, fees in a different major or in a floating local currency. A euro-paid family at a Singapore school, a sterling-paid family at a Tokyo school, a yen-paid family at a London school. This group carries the full currency risk and benefits most from active management.

The practical hedging tools
The financial industry offers a long catalogue of currency tools. For school fees, only four are practical for individual families. The rest are either over-engineered, too expensive, or require minimum sizes that exceed what most parents will allocate to fee planning.
| Tool | Best for | Indicative cost |
|---|---|---|
| Multi-currency current account | Holding fee-currency cash; in-the-moment transfers | Spread 0.3 to 0.6% |
| FX broker spot conversion | Quarterly or termly term conversions | Spread 0.4 to 0.8% |
| Forward contract (3 to 12 months) | Locking in annual fee at known rate | Forward points + 0.4% |
| Currency option (rare for families) | Asymmetric protection on large balances | Premium 1.5 to 3% |
Forwards and options are most easily accessed through a non-bank FX broker rather than a high-street bank. The retail-bank FX desks are typically loaded with spreads of 1.5 to 3 per cent, which is enough to erode the hedge's value.
Multi-currency accounts: a starting point
The simplest first step for any open-exposure family is a multi-currency current account. Several providers (Wise, Revolut Premium, HSBC Expat, Standard Chartered Premium, IBKR's cash account) offer cheap currency holding and conversion. The pattern that works is to hold a balance in the fee currency equal to one academic year of fees, replenished from salary at the rate you find acceptable, paying termly invoices directly from the multi-currency balance.
This is not a hedge in the strict sense. It is a pre-funding mechanism. The hedge benefit comes from the fact that you choose when to convert salary into fee currency, rather than being forced to convert at each invoice date. Our companion piece on currency accounts for school fees covers provider mechanics and the practical pitfalls.
Forward contracts on annual fee bills
A forward contract locks in a future exchange rate today, in exchange for paying or receiving the "forward points" that reflect interest-rate differentials. For school fees, the usual structure is to lock the annual bill in three to four tranches over the academic year, with the first tranche set in the term before the next academic year begins.
An example. A British family with a child at a school in Singapore in May 2026 expects to pay SGD 220,000 across the next four terms. They book four forwards, one for each term, locking SGD purchases at today's known rate. Whatever GBP-SGD does over the next twelve months, the family's GBP cost is fixed. They lose any upside if sterling rallies, but they remove the risk of an adverse move.
Forwards are most useful when (1) the exposure is large enough that a 5 per cent move would meaningfully affect family finances, (2) the timing is predictable (school invoices are reliably termly), and (3) the family has access to a broker who will book sizes of GBP 25,000 and up without excessive minimum charges. Larger family budgets can negotiate forward facilities through private bank accounts at materially better rates than retail brokers offer.
Timing rules that beat market timing
Most parents who try to time the currency market on fee payments lose money over multi-year horizons. The temptation to wait for "a better rate" before paying a term's fees is one of the most expensive habits in expat household finance.
A simple rule beats market timing in our analysis of the last decade. Convert one-twelfth of next academic year's fees from salary into the fee currency every month, regardless of the rate. This dollar-cost-average approach captures the long-run mean exchange rate without forcing the family to forecast. It works particularly well alongside a multi-currency account where the converted balance accumulates ahead of the next term invoice.
For larger exposures, a hybrid rule works better: convert 70 per cent of next year's fees on a schedule (monthly or quarterly), and reserve 30 per cent for a "patient" rate if the local currency weakens significantly. This caps the downside (most of the bill is locked) while preserving some upside.
Treating bonus income as a hedge
For expat families compensated through annual or biennial bonus cycles, the bonus itself can function as the fee hedge. The pattern: receive bonus in salary currency, immediately convert the portion earmarked for fees into the fee currency, hold in a multi-currency account, draw down through the year. This concentrates the currency conversion event into one date per year (predictable, easy to plan around) rather than twelve.
The risk is that bonus dates and fee dates do not line up. A bonus paid in March cannot fund September fees if the family does not have the discipline to ring-fence the cash. The simplest mitigation is to move the fee portion of the bonus into a labelled fee account on the day the bonus lands, before it gets absorbed into general spending. Our expat banking guide covers the account architecture for this.
Three mistakes we see most often
The first mistake is converting at the school portal. Many international schools accept credit card payment in the invoice currency. The implicit FX rate on the card is typically 2 to 3 per cent worse than a multi-currency account spot conversion. On a USD 40,000 annual bill that is USD 1,000 to USD 1,200 lost annually to a hidden FX spread.
The second mistake is the assumption that pegged currencies eliminate risk. The Hong Kong dollar is pegged to the USD inside a 7.75 to 7.85 band. That is a 1.3 per cent maximum range against USD, low but not zero. Against any non-USD home currency, full free-float exposure applies. Many euro-paid families in Hong Kong assume they are hedged because of the peg. They are not.
The third mistake is leaving the conversion until the invoice arrives. Schools typically invoice three weeks before the term-fee deadline. Converting on the invoice date concentrates risk into a single rate-fixing moment, with no flexibility to delay if rates are temporarily adverse. A multi-month pre-funding pattern materially reduces sequence risk.
