The Wise-to-Brubank Money Flow: Setting Up Your UK-Argentina Financial Pipeline
How to set up the standard Wise-to-Brubank monthly money flow that most British expats use: account setup, first transfer, recurring scheduling and FX optimisation.
Thomas SinclairWriter and editor · London
The Wise-to-Brubank pipeline is the financial backbone of British expat life in Argentina. Your UK income (salary, pension, savings drawdown) sits in your UK bank account in GBP. Wise converts it to ARS at the mid-market rate. Brubank receives the pesos and gives you a local debit card for Argentine daily life. Setting it up takes 30 minutes and saves you thousands in bank transfer fees over the year.
Step 1: Open both accounts
For related context, see Banking in Argentina as a UK Expat: Opening Accounts and Moving Money.
Wise: If you do not already have one, open at wise.com from the UK before you leave. Verification takes 1-2 days. Add your UK bank as a funding source (debit card or bank transfer).
Brubank: Open in Argentina once you have your CUIL. Download the app, register with passport + CUIL, and your account is live within minutes with a virtual Visa debit card. The physical card arrives by post in 5-10 days.
Step 2: Get your Brubank CBU
Your Brubank CBU (Clave Bancaria Uniforme) is a 22-digit number that identifies your specific account. Find it in the Brubank app under "Mi cuenta" or "Datos de la cuenta".
Example format: 0143-XXXX-XXXX-XXXX-XXXX-X
You also have a CVU (Clave Virtual Uniforme) which works similarly for fintech-to-fintech transfers. For Wise, you need the CBU.
Also note your CUIT/CUIL number — Wise asks for this as the recipient's tax ID.
Step 3: First transfer
In the Wise app or website:
1. Select Send money → GBP to ARS
2. Enter the amount in GBP
3. Recipient: your own name (as it appears on your Brubank account)
4. Bank: Brubank
5. Account number: your 22-digit CBU
6. CUIT/CUIL: your 11-digit tax ID number
7. Review the exchange rate and fee
8. Confirm and pay from your UK bank (debit or bank transfer)
Processing time: 1-2 working days for ARS to land in Brubank. Sometimes faster (same day for small amounts).
Typical fee: 0.5-1% of the transfer amount. On £1,000, expect £5-10 in fees. The exchange rate is mid-market. no hidden markup.
Step 4: Schedule recurring transfers
In the Wise app:
1. After completing your first transfer, Wise saves the recipient details
2. Go to Scheduled transfers (under Recipients)
3. Set frequency: monthly on a specific date
4. Set amount: your regular monthly living expenses in GBP
5. Confirm
Wise automatically converts and sends each month. You receive pesos in Brubank like clockwork.
Timing tip: Argentine inflation means the ARS you receive loses value over time. Transfer monthly (or even fortnightly) rather than quarterly to avoid holding depreciating pesos.
Step 5: Daily spending
With pesos in Brubank, you spend using:
- Brubank Visa debit card — tap at any Visa-accepting merchant
- Transfer to Mercado Pago — for QR payments at shops and restaurants
- Cash withdrawal — Brubank's free ATM withdrawal allowance covers most needs
- Bill payments — transfer to utility companies or pay through Mercado Pago
Optimisation: timing the FX
The GBP/ARS rate fluctuates. Minor optimisations:
- Avoid weekends: Wise processes weekend transfers on Monday, potentially at a different rate
- Transfer during UK business hours: the live rate is most liquid when London markets are open
- Split large amounts: if you need to move £10,000+ (flat deposit, car purchase), consider splitting into 2-3 transfers over a week to average the rate
For amounts under £2,000/month, the rate difference between days is negligible. Do not overthink it.
The alternative flows
Wise to Ualá: works via CVU. Same process, Mastercard instead of Visa.
Wise to traditional bank (Galicia, HSBC): works via CBU. Slightly slower processing (2-3 days vs 1-2 for Brubank).
Revolut card spending: does not involve Brubank at all. You spend directly from your Revolut GBP balance converted at point of sale. Good for daily spending; does not help with rent or bank transfers.
Monthly cost of the pipeline
Compare to a UK bank SWIFT transfer: £15-40 per transaction plus 3-5% FX markup = £45-90 per £1,000. Over a year: £540-1,080. The Wise-Brubank pipeline saves £400-900/year versus traditional banking.

Frequently Asked Questions
How long does a Wise transfer to Brubank take?
1-2 working days typically. Small amounts sometimes arrive same-day. Large amounts (over £5,000) may take 3-4 working days due to compliance checks.
What is the CBU and where do I find it?
The CBU is a 22-digit Argentine bank account identifier. Find it in the Brubank app under 'Mi cuenta' or 'Datos de la cuenta'. You need it for receiving transfers.
Is it better to transfer monthly or quarterly?
Monthly or fortnightly. Argentine inflation erodes the value of pesos over time. Keeping peso balances low and transferring frequently preserves your purchasing power.

Approximately £5-10 per £1,000 transferred. Over a year of monthly £1,500 transfers, total cost is £60-120 — saving hundreds versus bank SWIFT transfers.
