Nostro and vostro: why a USD wire takes days
A nostro account is an account a bank holds with a foreign bank in that bank's currency — "ours" from the holder's side. The same ledger is the vostro — "yours" — for the bank that holds it. These paired accounts are what actually move a SWIFT payment.
KEY FACTS
| What it is | Two names for one correspondent account between banks |
|---|---|
| Nostro | "Ours": the account your bank holds with a foreign bank |
| Vostro | "Yours": the same account on the other bank's books |
| USD from the UAE | Settles on a US correspondent's ledger; 2 to 5 business days |
| AED inside the UAE | UAEFTS, same business day |
| IWGT USD payout | 2 to 5 business days, own-name accounts only |

One account, two names
Nostro ("ours") is the account Bank A holds with Bank B, in Bank B's currency, on Bank A's books; vostro ("yours") is the same account as Bank B records it, every entry mirrored on both ledgers. SWIFT carries the instruction; the nostro-vostro pair is where value changes hands.
Why USD wires from the UAE take 2 to 5 days
Dollar settlement happens in the United States, so a UAE bank keeps a pre-funded USD nostro with a New York correspondent: the sender's bank sends an MT103, the credit posts to that nostro, and only then does the UAE bank credit the client. The message travels in seconds; the ledger entries across one to three correspondent pairs take days, because each correspondent works its own business days and cut-off and any compliance query pauses the entry. Dirhams skip this layer over the same-day UAEFTS rail. Fees on the chain are mapped in SWIFT transfers sent from the UAE.
Why it matters when selling USDT in the UAE
When you sell USDT through a licensed desk and elect dollars, the on-chain leg is as fast as for dirhams; the correspondent leg is what takes 2 to 5 business days, as of September 2026 (see selling USDT for US dollars). Choose AED and the payout lands the same business day.
Illustrative example
You sell 400,000 USDT at a 0.15% spread (published bands 0.08% to 0.40%, as of September 2026): the desk's bank wires USD 399,400. It leaves Dubai on Tuesday after the New York cut-off; Wednesday the first correspondent posts it on; Thursday your bank's nostro is credited and your account with it. Paid in AED, the dirhams would have arrived on Tuesday.
FAQ
Is a nostro account the same as a vostro account?
Yes — they are two names for one account. The bank that keeps money abroad calls it nostro ("ours"); the bank holding the money calls the same account vostro ("yours"). Every transaction posts to both ledgers as a mirror entry.
What is a loro account?
Loro is Latin for "theirs". When Bank A talks to Bank C about the account Bank A holds with Bank B, it calls that account a loro. You rarely meet the term outside correspondent-banking departments.
Can an individual or a company open a nostro account?
No. Nostro accounts exist only between regulated financial institutions. Clients meet them indirectly — through correspondent deductions and the 2–5 business day timeline on foreign-currency wires.
Do nostro accounts have anything to do with crypto?
Only at the settlement step. A USDT sale settles on-chain in minutes, but the fiat payout still travels across correspondent ledgers. Dollars mean a nostro chain and 2–5 business days; dirhams mean UAEFTS the same business day.
Sell USDT with a settlement date you can plan around
IWGT is a VARA-licensed Broker-Dealer in Dubai (licence VL/24/12/002). USD settles by SWIFT in 2–5 business days to own-name accounts; AED settles by UAEFTS the same business day. Spread 0.08–0.40% by ticket size, published openly.
