Rolling Reserve
A percentage of a merchant's card volume that the acquirer withholds from each settlement and releases after a holding period, as cover against chargebacks.
What it means
You've cleared €500,000 through a card acquirer this month. The settlement statement shows €440,000 landing: fees came off, and €50,000 sits on a line called "reserve held". It'll come back, but not this month. That's a rolling reserve. The acquirer keeps a fixed percentage of each period's volume and releases it after a holding period, so there's always a running balance of your money on its books.
It exists because a card payment can be reversed months after it settles. If a player disputes March deposits in June and you've gone dark, the acquirer eats the chargeback. The reserve is its insurance, and gambling is one of the verticals where acquirers won't sign without it.
How it works
| Parameter | Typical range | Example |
|---|---|---|
| Reserve percentage | 5-15% of gross volume (typical) | 10% |
| Holding period | 90-180 days (typical) | 180 days |
| Basis | Gross processed card volume, before fees | €500,000 a month |
| Release | Each period's holdback returns once its period ends | Month 1's €50,000 comes back in month 7 |
| Cap | Sometimes a hard ceiling in euros, often none | None |
| Exit | Final balance released 90-180 days after the contract ends | €300,000 paid out over six months |
Worked example
A casino brand doing €500,000 a month in card deposits, 10% held for 180 days.
- Month 1: €50,000 withheld. Locked: €50,000.
- Month 2: another €50,000. Locked: €100,000.
- Month 6: locked balance reaches €300,000.
- Month 7: month 1's €50,000 returns, month 7's €50,000 goes in. Locked stays at €300,000.
At steady state the acquirer holds six months of reserve, €300,000 against €6m in annual volume. At a 12% annual cost of money, the reserve costs €36,000 a year in dead capital. That's 0.6% of volume on top of the headline processing fee. Get the same brand down to 5% for 90 days and the locked balance falls to €75,000, the hidden cost to €9,000. Model it against GGR, not against margin, because the reserve comes out of gross deposits before a single bet is placed.
Why gambling merchants get them
Card schemes code gambling as MCC 7995, and both Visa and Mastercard treat it as high-risk by default. Three reasons. Chargebacks are easy for a cardholder to win ("I didn't authorise this" against a deposit that's already been lost). Losses skew large and arrive late. And if a brand folds, every open dispute lands on the acquirer. Visa's and Mastercard's excessive-dispute programs start at dispute ratios in the 0.9% to 1.5% band, and it's the acquirer that gets fined when a merchant crosses the line. Curacao-licensed brands, crypto-adjacent flows and merchants with no history get the top of the range. MGA or UKGC licensees with twelve clean months get the bottom. The high-risk acquiring article covers how acquirers price that risk.
Negotiation levers
- Processing history: six to twelve months under 0.5% chargebacks is the strongest argument you have. Ask for a written step-down (10% to 7% to 5%) tied to that metric.
- Licence tier and audited financials move you down the range.
- 3-D Secure on every card deposit shifts fraud liability to the issuer and cuts your dispute count.
- A cap: a fixed ceiling in euros beats an uncapped percentage once volume grows.
- Fixed collateral instead: a one-off deposit can be cheaper than a 180-day rolling hold at the same risk level.
- Split volume across two or three acquirers through payment orchestration, so no single reserve grows large and you keep a fallback.
- Move deposits to push payments: PIX, Interac, iDEAL and open banking can't be charged back, so that volume carries no reserve at all. It also lifts acceptance rate, which acquirers read as a proxy for fraud pressure.
How platforms handle it
Platforms don't set reserves; acquirers do. What a platform decides is how many acquirers and local methods one cashier can route to. In the iGamingHub catalog, Softswiss lists around 200 payment methods with Visa, iDEAL, EPS, PIX and Interac among its integrations. SoftGamings shows the longest named list in the catalog: Visa, Mastercard, Skrill, Neteller, Trustly, iDEAL, Paysafe, PIX and Interac, across roughly 150 methods. Slotegrator pairs Visa and Mastercard with Bitcoin, Ethereum and USDT, the usual mix for Curacao-facing brands where card reserves run highest. iGamingHub tracks the integrations a platform declares, not the acquirer terms behind them.
Common confusions
A rolling reserve rolls: money goes in every period and comes out on a lag. A fixed (or upfront) reserve is one amount held for the life of the contract, often sized at 5-10% of expected monthly volume. A settlement delay is the gap between a transaction and payout, usually T+2 to T+7 for gambling merchants; it holds all of the money for days, not part of it for months. A chargeback fee is a per-dispute charge, €15 to €40 (typical), billed whether or not you win; it's a cost, not a hold. And if your platform acts as merchant of record, the reserve sits on its contract rather than yours.
