What it means
When you top up a payment wallet with $200, that money does not stay in your bank account and does not become the issuer's to spend. It becomes a liability the issuer owes you, recorded as e-money outstanding, and the matching cash sits in a safeguarding account at a bank.
The distinction from a bank deposit matters more than it sounds. Deposits are usually covered by a deposit guarantee scheme and can be lent out by the bank, while e-money is not lent out and is protected instead by segregation of the underlying funds, so the protections work in completely different ways.
Regulators generally impose three requirements on issuers: hold customer funds separately from company money, hold them at 100% of the balances owed, and redeem them at face value on demand. Those rules are why a well-run e-money issuer looks unusual on paper, with a very large asset and a matching very large liability that neither belongs to shareholders nor flows through the income statement.
Issuers earn money in a few predictable ways. Interchange on card spending, foreign exchange margin, top-up or withdrawal fees, subscription tiers for business accounts, and in some regimes the interest earned on the safeguarded float, though several jurisdictions require that interest to be passed on or restrict it entirely.
The nuance to keep straight is that not every digital balance is electronic money. A gift card usable only in the issuer's own shops is normally outside the definition, and a stablecoin or a bank current account each sit in a different regulatory box, so the label depends on the legal structure rather than on the fact that a balance appears in an app.
In practice
Real-world examples.
Example
A city transport authority issues a contactless travel card that riders top up at machines. The balances are electronic money, held in a segregated account, and unspent value must be refundable when a rider hands the card back.
Example
A gig-economy platform pays 12,000 couriers into in-app wallets each week. Couriers can spend the balance with a linked card or move it to a bank account, and the platform must safeguard every dollar sitting in those wallets overnight.
Example
A corporate expense provider issues prepaid cards to 800 employees with monthly limits. Finance loads $400,000 onto the programme each month, and because the value is e-money rather than a credit line, the company's exposure is limited to what it has already loaded.
Formula
Calculation
E-money outstanding = Number of active accounts x Average balance. Safeguarded funds must equal 100% of e-money outstanding, and float income = Safeguarded funds x Interest rate.
Kestrel Pay, an e-money issuer, runs consumer wallets and reports the following at the year end.
Active wallets = 240,000
Average balance per wallet = $75
E-money outstanding = 240,000 x $75 = $18,000,000
Required safeguarded funds = 100% x $18,000,000 = $18,000,000
If the safeguarding account earns 4% a year and the regime permits the issuer to retain that interest:
Float income = $18,000,000 x 0.04 = $720,000 per year
The $18,000,000 appears on both sides of the balance sheet, as a safeguarded asset and as a liability to wallet holders, so it adds nothing to shareholder value on its own. Only the $720,000 of float income, alongside interchange and fees, reaches the income statement, and a fall in rates from 4% to 1% would cut that line to $180,000 without any change in customer numbers.Case study
Seen in the real world.
This is a fictional, illustrative scenario. Larkfield Wallet grew to 240,000 users and $18,000,000 of balances during a period of high interest rates, and float income of roughly $720,000 a year quietly covered about a third of its operating costs. Management described the business as profitable and planned hiring accordingly.
When policy rates fell, float income dropped to around $180,000 and the gap became obvious within two quarters. The underlying issue was that a temporary rate environment, not the payments product, had been carrying the business model.
Larkfield responded by introducing a $4 monthly plan for business users, negotiating better interchange terms and cutting the cost of top-ups, rebuilding earnings from customer activity rather than from rates. The illustrative point is that float income is a genuine revenue line, but it is a bet on interest rates rather than evidence that the product itself pays.
Watch out
Common mistakes.
- Treating an e-money balance as a bank deposit. The money is safeguarded rather than guaranteed by a deposit protection scheme, so the protection mechanism is different even though both feel like cash in an app.
- Counting safeguarded funds as company assets available for spending. They belong to customers, cannot be used for working capital, and using them for anything else is a serious regulatory breach.
- Assuming float income is dependable profit. It moves directly with interest rates and can shrink to almost nothing while customer numbers stay flat.
Questions
People also ask.
Is electronic money the same as cryptocurrency?
No, because e-money is denominated in an ordinary currency and redeemable at face value from a regulated issuer, while most crypto assets have neither feature.
Can an e-money issuer lend out customer balances?
Generally no, since safeguarding rules require the funds to be held in full and available for redemption on demand.
What happens to my balance if the issuer fails?
Safeguarded funds are held apart from the issuer's own money and are intended to be returned to customers ahead of general creditors, though an administration process can still take time.
