Nostro is an Italian word meaning ‘ours’. So Nostro account means – “Our account with you”
Nostro accounts are generally held by a domestic bank (our bank) in a foreign country (with a foreign bank).
The account is maintained in that foreign currency.
For example, SBI account with HSBC in U.K.
Vostro is an Italian word meaning ‘yours’. Hence, Vostro account means – “Your account with us”
Vostro accounts are generally held by a foreign bank in our country (with a domestic bank). It is generally
maintained in Indian Rupee (if we consider India)

Loro is an Italian word meaning ‘theirs’. Therefore, it means – “Their account with them”
Loro accounts are generally held by a 3rd party bank, other than the account maintaining bank or with whom
account is maintained.
