The Closed Loop / The dead rail
When the rail has gone

The cap survives the rail, and that is the whole problem

A closed bank account does not delete the deposit that was paid from it. The rail keeps its cap, the cap cannot be paid, and the money behind it stops moving until the operator re-routes it. The arithmetic of that wait is on this page.

Direct answerWhen the rail behind a deposit has gone, its cap remains on the account and cannot be paid. The operator can hold the money until a replacement is provided, re-route it against a signed indemnity, or let a fresh rail carry a new and much smaller cap. None of the three is instant.

Why the cap outlives the rail

The cap is a record of a completed payment, not a reference to a live account. An operator that closed its own records whenever a card expired would lose the audit trail that the loop exists to create, so the rail stays in the ledger with its cap intact and a note that it cannot be paid. What a reader sees is a withdrawal that is approved, and then does not arrive.

The expired card

The commonest case. A card that has been replaced keeps the cap of the deposits it carried, and the number attached to that cap no longer exists. The replacement card is a different rail, with a cap of its own that starts at zero.

The closed bank account

A bank account that has been closed cannot receive the return, and unlike a card there is no issuer to appeal to. The money is usually held until the reader supplies a different account in the same name, and the new account then needs its own rail.

The dead wallet or address

An e-wallet account that has been closed, or a crypto address that a reader no longer controls, is the same problem with no reversal route at all. Where the destination is an address rather than an account, the loop can only travel back to that exact address, so losing it is losing the rail.

S4, worked: 200.00 behind a card that expired 14 months agopaid in 200.00, one rail, card now expired the cap 200.00 - 0.00 = 200.00 requested = 200.00 route 1 - hold until a replacement rail reaches in the reader’s hands: nothing moves until a rail is provided capacity the replacement card opens at 0.00 until it takes a deposit route 2 - re-route against an indemnity the form 1 signed indemnity, accepting the chargeback risk a fee 15.00 = 7.5% of the 200.00 held the wait 11 working days exposure the operator takes 200.00 + a 20.00 dispute fee = 220.00 against a 200.00 payment = 110.0% of the sum route 3 - a fresh rail with a test deposit test deposit 10.00 -> cap 10.00 still stuck 200.00 - 10.00 = 190.00

The three routes are not equally open, and the second line of route 3 is the one to read twice. A fresh rail does not inherit the old one’s cap: a 10.00 test deposit on a working card opens 10.00 and leaves 190.00 behind a rail that still does not work. Re-route is the only route that actually moves the whole 200.00, and re-route is the route that requires the indemnity, carries the 15.00 fee and takes the 11 working days.

The indemnity, and why an operator wants one

Re-routing means paying a rail that never received the money. The risk the operator is accepting is specific: the card issuer can charge back the original 200.00 up to its own dispute window, which on the sample is 540 days from the transaction. If the money has already been sent to a replacement rail, the operator has paid twice and can recover once. The indemnity shifts that risk to the reader by agreement.

Read the indemnity before signing it. The document usually says that the reader will repay the amount if the original payment is reversed. What it decides is who carries a double payment, and the arithmetic above - 220.00 of exposure against a 200.00 payment, or 110.0% - is why. It is a reasonable thing for an operator to ask for and an equally reasonable thing for a reader to read twice.

Ordering the three routes

  1. Write down which rail has gone and how much cap sits on it. One rail, one figure - 200.00 on S4. Everything after this is about that figure.
  2. Check the other rails first. If any working rail has spare cap, a request does not have to touch the dead one at all, and the dead cap can be left alone - which is often the cheapest answer, because a dead rail costs nothing while it is untouched.
  3. Decide between holding and re-routing. Holding is free and slow; re-routing is fast and costs a fee plus an undertaken risk. A reader with no timeline should hold; a reader who needs the money out in a fortnight should ask what the re-route costs before deciding.
  4. Ask what the replacement rail will do. A new card is a new rail with a zero cap, and it will need its own completed deposit before it can return anything. Replacing a card does not restore a cap.
  5. Do not deposit to the dead rail. A payment attempted to a closed account or an expired card can fail after it appears in the balance, and a failed deposit removes capacity rather than adding it.
