making payments in its country's currency, usually using its own access to primary clearing arrangements (generally with the central bank in the country where the currency is considered a local currency). In some cases, the facilitator bank may not be a primary clearing member but they will have the ability to make payments in local currency, possibly through another bank in the same country. Loro accounts There is also the notion of a loro account ("theirs"), which is a record of an account held by a second bank on behalf of a third party; that is, my record of their account with you. In practice this is rarely used, the main exception being complex syndicated financing. In the same style as above: A loro is our account of their money, held by you. Accounting Conventions A bank counts a nostro account with a debit balance as a cash asset in its balance sheet. Conversely, a vostro account with a credit balance (i.e. a deposit) is a liability, and a vostro with a debit balance (a loan) is an asset. Thus in many banks a credit entry on an account ("CR") is regarded as negative movement, and a debit ("DR") is positive - the reverse of usual commercial accounting conventions. With the advent of computerized accounting, nostros and vostros just need to have opposite signs within any one bank's accounting system; that is, if a nostro in credit has a positive sign, then a vostro in credit must have a negative sign. This allows for a reconciliation by summing all accounts to zero (a trial balance) – the basic premise of double-entry bookkeeping. Typical usage Nostro accounts are mostly commonly used for currency settlement, where a bank or other financial institution needs to hold balances in a currency other than its home accounting unit. For example: First National Bank of A does some transactions (loans, foreign exchange, etc.) in USD, but banks in A will only handle payments in AUD. So FNB of A opens a USD account at foreign bank Credit Mutuel de B, and instructs all counter-parties to settle transactions in USD at "account no. 123456 in name of FNBA, at CMB, X Branch". FNBA maintains its own records of that account, for reconciliation; this is its nostro account. CMB's record of the same account is the vostro account. Now, FNBA sells AUD1,000,000 to C (a counterparty who has
