Send money to Poland from Kuwait, as a euro credit
Read this part before anything else. Grey does not convert to zloty on this corridor. What reaches Poland is a euro credit into the recipient's Polish IBAN through SEPA, at PKO Bank Polski, Bank Pekao or mBank, and their own bank handles the conversion into zloty if they want it. That suits some senders very well and others not at all.

What actually happens on this corridor
Poles in Kuwait are mostly on the construction and engineering side: site and project managers, civil and structural engineers, surveyors, specialists brought in by European contractors working on Kuwaiti infrastructure and plant. It is a real presence and a well paid one, and most people in it are sending money to a household that thinks and budgets in zloty.
Which is why the mechanics need stating plainly. Grey sends euro. The transfer travels through SEPA and lands in a Polish IBAN at PKO Bank Polski, Bank Pekao or mBank as a euro credit. If the receiving account is a zloty account, the recipient's own bank converts it on arrival at that bank's rate, which neither you nor Grey controls and which you cannot see from Kuwait. If the receiving account is a euro account, and plenty of people working with European contractors hold one, nothing converts and the money simply arrives.
On the funding side, Grey holds no Kuwaiti dinar balance. You hold US dollars provided by Lead Bank, pounds or euro. Holding euro means the money you send is euro from beginning to end.
Three steps to a Polish IBAN
Sign up
The account is free, opens in about five minutes on a phone, and asks for one valid identity document.
Fund
Hold euro, US dollars provided by Lead Bank or pounds, funded by salary, contract payments or a transfer you send in.
Send euro
Enter the Polish IBAN, check the euro amount against the fee, and confirm. The euro travels to Poland through SEPA.
What this costs, and where the cost you cannot see sits
The part to be honest about is the other side. Where the euro lands in a zloty account, the receiving bank in Poland converts it, and that bank sets its own rate and may add its own charge. That cost is real, it does not appear anywhere in the Grey app, and it is the reason this corridor suits some people and not others.
So the comparison here is not Grey against another provider on a euro to zloty rate. It is whether a euro credit plus a Polish bank's conversion works out better for your recipient than a service that converts to zloty before it arrives. For somebody with a euro account in Poland it plainly does. For a household that needs zloty in hand and banks somewhere with unforgiving conversion terms, it may well not, and you should work that out before you send rather than after.
How the rate works when there is one
Where you are converting into euro, from dollars or pounds, Grey shows the live rate before you confirm and fixes it there. The euro figure on screen is the euro figure that reaches the Polish IBAN. That part is settled and does not change afterwards.
Where you hold euro already, no rate is involved on Grey's side at all. What leaves your balance is what arrives, less the fee you saw.
Worth knowing from the Kuwaiti end: the dinar is the highest valued currency unit in the world and is managed against a dollar weighted basket, so quoted rates around Kuwait look almost unchanging. That steadiness is a property of the dinar's management, not evidence that a margin is small. And the zloty conversion, when it happens, happens after all of this and in someone else's hands.
Grey against a transfer from your Kuwaiti bank
A Kuwaiti bank sending to Poland through Gulf Bank, Boubyan Bank or National Bank of Kuwait uses SWIFT, which adds an outbound charge and the possibility of a correspondent deduction, and may convert at the bank's own rate into either euro or zloty without showing you the working. Grey's route is narrower and more honest about its limits: euro over SEPA into the IBAN, priced before you confirm, trackable to settlement, with the zloty conversion left visibly to the Polish bank rather than hidden inside the transfer.
What lands in the Polish account
Your recipient needs no Grey account. What arrives is a euro credit, and what happens next depends on the account it lands in.
Polish IBANs
PKO Bank Polski, Bank Pekao and mBank are supported, and the IBAN is the only account detail you need to enter.
A euro credit, not zloty
The money arrives as euro. A euro account holds it as euro. A zloty account converts it at the receiving bank's rate, which is set in Poland and not by Grey.
SEPA and SEPA Instant
Delivery runs on SEPA, and on SEPA Instant if the Polish bank supports it. Sent from a funded balance, the euro usually posts within minutes.
Getting money into the account
No dinar top up exists, so the balance is filled in whichever currency your contract pays, and on this corridor euro is often worth asking for.
Paid in by a contractor or client
Share your Grey account details with whoever pays you. European contractors frequently settle in euro, which lands straight in the balance you want for Poland.
A transfer you send in
Move euro, dollars or pounds in from an account you already hold, then send to the Polish IBAN once the funds have landed.
A euro balance kept ready
Holding euro between payments means the only variable left is the Polish bank's conversion, which is the one you should be watching anyway.
Each funding route shows its fee before you confirm it, so Grey's whole side of the cost is in front of you before the money moves.
What this corridor is used for
Household support during a posting
A site or project engineer sending a regular amount to a family in Poland for the length of a contract. This is the case where the receiving account's currency matters most, so it is worth asking which one they hold.
Mortgage and housing
Instalments and charges on a property in Poland that carry on while the work is in Kuwait. Fixed dates, and a good reason to hold euro so the amount leaving is predictable.
Euro denominated obligations
Payments that are already priced in euro, to a supplier, a professional or an account held in euro. These are the ones this corridor handles without any conversion question at all.
Savings held in euro
Moving earnings into a euro account in Poland to sit there as euro, rather than converting twice and back again later.
The pattern here follows construction and engineering contracts more than it follows family remittance alone.
Where Grey fits on this corridor
From Kuwait the account is free, opens in about five minutes and asks only for a valid identity document. The balances are euro, US dollars provided by Lead Bank and pounds.
Before the first transfer, ask the person in Poland which currency their account is held in. That single question decides whether this corridor is a good fit or an expensive one, and it is much easier to ask now than to explain afterwards.
FAQs
Does Grey convert my money into zloty?
No. Grey sends euro into the Polish IBAN through SEPA. If the account is held in zloty, the recipient's own bank converts it on arrival.
Who sets the rate when the euro becomes zloty?
The receiving bank in Poland does. That conversion happens after the transfer arrives, at their rate, and it is not visible in the Grey app.
Which Polish banks can receive a euro credit from Kuwait?
PKO Bank Polski, Bank Pekao and mBank are supported, and the IBAN is the only account detail Grey asks you for.
Who does this corridor actually suit?
Anyone whose recipient holds a euro account in Poland, or who is paying an obligation already priced in euro. Then nothing converts at either end.
Who should think twice before using it?
Anyone whose family needs zloty in hand and banks somewhere with poor conversion terms, since that conversion happens beyond Grey's sight and control.
Can I hold Kuwaiti dinar on Grey before sending to Poland?
No. There is no dinar balance. You hold euro, US dollars provided by Lead Bank, or pounds, and send euro from one of those.
What should I ask my family in Poland before the first transfer?
Which currency their account is held in. A euro account makes this straightforward, and a zloty account adds a conversion you cannot see.
Is there any conversion on Grey's side if I hold euro?
No. Euro leaving a euro balance arrives in the Polish IBAN as euro, so Grey applies no rate and takes no exchange margin.
Is SEPA Instant available for Polish accounts?
Yes, where the receiving bank supports it. Transfers from a funded Grey balance typically arrive within minutes over SEPA in any case.
Does my recipient in Poland need a Grey account?
No. The euro credit posts to their existing Polish account as an ordinary SEPA payment, with nothing for them to sign up to.
Why do rates quoted in Kuwait look so flat?
The dinar is managed against a dollar weighted basket rather than floating, so a steady headline says nothing about the margin underneath it.
