The savings keep coming back out. The account isn't broken.
Modern banking is optimised end to end for moving money instantly. That's a feature almost everywhere — and a problem in the one case where the person you need to slow down is you.
Everything is designed to remove friction
Transfers settle in seconds. Cards are stored in every checkout. One-tap payment is the default on both major phone platforms. Each of these is a genuine improvement, and together they mean the distance between deciding to spend and having spent has collapsed to roughly zero.
The usual advice is to reintroduce friction by hand: move savings to a different bank, delete the app, keep the card out of the wallet, give the account an aspirational nickname. These help at the margin. They also share one weakness — every one of them can be undone in under a minute by the same person who set them up, in exactly the mood where undoing them seems reasonable.
What a commitment device is
Economists call the alternative a commitment device: a choice made deliberately in a calm moment that removes an option from your future self. The classic illustration is Ulysses ordering his crew to tie him to the mast — not because he expected to resist the sirens, but because he knew he wouldn't, and arranged in advance for resistance not to be required.
The research on this is reasonably settled. In the widely cited SEED experiment run with a Philippine bank, customers offered an account that voluntarily restricted their own access until a date or goal they set ended up saving substantially more than an otherwise comparable group. The intervention didn't make anyone more motivated. It made withdrawal unavailable.
Apsis is that mechanism, with the enforcement moved out of a bank's policy and into a contract on a public blockchain. You choose an amount and a date; a ten-minute cooling-off window lets you reverse the decision while it's still a decision; after that the money is unreachable until the date arrives, at which point it returns to your bank account with the interest it earned.
The realistic options, compared
| Approach | What stops you | How it fails |
|---|---|---|
| Budgeting app | Information and alerts. | Reports the decision; can't prevent it. |
| Savings sub-account | A label and a little friction. | A transfer out takes about forty seconds. |
| Certificate of deposit | An early-withdrawal penalty. | A price you can simply choose to pay. |
| A trusted person | Having to ask them. | Strains the relationship; earns nothing. |
| Apsis | No release function exists. | Genuinely unavailable in an emergency. |
Common questions
How do you actually lock money so you can't spend it?
There are four practical options. Give it to someone you trust to hold. Buy a certificate of deposit, which imposes a penalty rather than a barrier. Use a savings account with withdrawal limits, which slows you down without stopping you. Or use a commitment device like Apsis, where the money is held in a contract with no early-release function at all — the only one of the four with no way through for anyone, including the company that built it.
Why don't budgeting apps fix this?
Because they operate on information, and the problem usually isn't information. Knowing you've overspent, seeing a category go red, or getting a notification are all inputs to a decision you're already making badly in that moment. Budgeting tools are excellent at telling you what happened. They have no ability to prevent it.
Aren't savings sub-accounts and envelopes enough?
For a lot of people, yes — and if labelled pots work for you, keep using them, they're free and insured. They fail specifically when the label is the only thing standing between you and the money, because a label is a suggestion. Moving funds out of a named sub-account takes about as long as moving them out of any other account.
How much should I lock?
Less than feels right on the first attempt. Fund an accessible emergency account first, then lock only the surplus above it, on a short term to begin with. The value of a first lock is learning how being unable to reach money actually feels — not moving a large amount before you know.
