The Lowest Rejection Rate in Crypto Belongs to Licensed Custody
Licensed custody providers face the least bank resistance of any crypto profile. The reason is structural: custody is passive balance management with minimal payment velocity, no chargeback exposure, and a clear regulatory perimeter. A bank looking at a custodian is reading an operational-risk profile it recognises, not a payments profile it does not.
The corollary matters commercially: a custodian that also runs an exchange, a lending book, or an on-ramp loses that advantage, because the bank now underwrites the riskiest activity in the entity rather than the safest. Separating custody into its own licensed vehicle is a banking decision as much as a regulatory one.
Client Assets Are Not the Custodian’s Assets
MiCA Article 70 requires a crypto-asset service provider holding client funds to deposit them with a central bank or credit institution by the end of the business day following receipt, held so that they are separately identifiable from the firm’s own assets.[1] For a custodian, the fiat leg of that requirement is usually small but the principle governs the whole relationship.
On the crypto leg, the segregation question is about wallet architecture rather than bank accounts: which keys control which balances, whether client assets are pooled or individually addressed, and whether the custodian can reconstruct per-client entitlement from on-chain state plus its own ledger. Banks ask about this because a custodian that cannot answer it is a custodian whose insolvency would be unresolvable.
Banks Test a Custody File as Operational Risk, Not Compliance
Key management and storage split. Documented segmentation across hot, warm, and cold storage, with multi-party computation or multi-signature arrangements, ceremony procedures, and geographic distribution of key material. This is read as operational risk: the question behind it is whether a single compromise or a single departing employee can move client assets.
Insurance. Specie cover for cold storage and crime cover for hot wallets, with the policy limits set against actual assets under custody rather than a headline figure. Banks ask for the schedule, not the certificate.
Proof of reserves and attestation. Where the custodian publishes one, banks ask about methodology and cadence. An attestation that proves assets exist without proving liabilities is read as partial, and saying so plainly is better received than presenting it as complete.
Analytics and screening. A live contract with an institutional-grade blockchain analytics provider, configured. Supervisory expectations for analytics use were set out by the New York State Department of Financial Services in an industry letter of 17 September 2025, and European institutions apply comparable expectations through the amended EBA money-laundering risk-factor guidelines, EBA/GL/2024/01.[2][3]
Four Account Layers, and Only the Client-Fiat Layer Is Slow
| Layer | Institution | Difficulty | Timeline |
|---|---|---|---|
| Operating account | Bank or EMI | Routine once licensed | 2–6 weeks |
| Client-fiat account (where held) | Credit institution (MiCA Art 70) | Moderate; smaller balances than an exchange | 6–12 weeks |
| Treasury and multi-currency | Bank or EMI | Routine | 2–6 weeks |
| Insurance premium banking | Bank | Routine | 2–4 weeks |
Costs sit at the low end of the crypto range because payment velocity is low: operating EMI maintenance of €100 to €500 a month is typical, and card acquiring is usually not required at all. Ranges are indicative across the partner network as of .
How Jagelski & Partners Helps
Custody placement is the most straightforward banking work in crypto, and the assessment reflects that: it confirms the regulatory perimeter, checks whether other activities in the same entity will drag the underwriting toward a riskier profile, and places the operating and client-fiat layers against institutions whose appetite already admits licensed custodians.
Where a custodian intends to add exchange, lending, or on-ramp activity later, we say at the assessment stage what that will do to the banking relationship, because the cheapest time to structure it into a separate vehicle is before the accounts are opened.
Frequently Asked Questions
Because custody is passive balance management: low payment velocity, no chargeback exposure, and a clear regulatory perimeter. A bank underwriting a custodian is assessing operational risk it recognises rather than a payments profile it does not.
Licensed custody providers sit at the lowest rejection-rate band of any crypto profile placed through the partner network.
Substantially, and it is worth planning around. A bank underwrites the riskiest activity in the entity, not the safest, so a custodian that also runs an exchange, a lending book, or an on-ramp is priced as that business instead.
Separating custody into its own licensed vehicle is a banking decision as much as a regulatory one, and the cheapest time to do it is before the accounts are opened.
Under MiCA Article 70, client funds must be deposited with a central bank or credit institution by the end of the business day following receipt, held so they are separately identifiable from the firm’s own assets. For a custodian the fiat leg is usually small, but the principle governs the relationship.
On the crypto leg, segregation is a wallet-architecture question: whether client assets are pooled or individually addressed, and whether per-client entitlement can be reconstructed from on-chain state plus the ledger.
Documented segmentation across hot, warm, and cold storage, multi-party computation or multi-signature arrangements, ceremony procedures, and geographic distribution of key material.
Banks read this as operational risk rather than compliance. The question behind every item is whether a single compromise, or a single departing employee, can move client assets.
Not by rule, but it is asked for, and the schedule matters more than the certificate. Specie cover for cold storage and crime cover for hot wallets, with limits set against actual assets under custody rather than a headline figure.
A policy whose limit is a small fraction of assets under custody is worse than none in the conversation, because it invites the question of what happens above the limit.
As useful but partial unless it covers liabilities. An attestation proving assets exist without proving what is owed against them does not establish solvency, and banks know that.
Saying so plainly is better received than presenting an assets-only attestation as complete. Methodology and cadence are asked about specifically.
Yes, live and configured rather than intended. Supervisory expectations for analytics use were set out by the New York State Department of Financial Services in an industry letter of 17 September 2025, and European institutions apply comparable expectations through the amended EBA money-laundering risk-factor guidelines, EBA/GL/2024/01.
Stated intention does not satisfy the requirement; institutions ask for the contract and the configuration.
At the low end of the crypto range, because payment velocity is low. Operating EMI maintenance of 100 to 500 euro a month is typical, and card acquiring is usually not required at all.
Ranges are indicative across the partner network as of June 2026 and move with balance profile and jurisdiction.
Operating and treasury accounts run 2 to 6 weeks. A client-fiat account at a credit institution, where the custodian holds one, runs 6 to 12 weeks, which is faster than the equivalent for an exchange because the balances and velocity are lower.
No. Jagelski & Partners is paid by the institution that takes the business, through a referral or revenue-share arrangement, not by a fee billed to the client. The pricing is the institutional rate, with no markup and no onboarding fee.
