Simply put, foreign exchange business involves the issue of the basic currency for bookkeeping. China requires RMB as the bookkeeping base currency (foreign currency should also be converted into RMB when reporting). Therefore, at the time of entry, the currency is converted into RMB according to the contract or the foreign exchange rate of the day; When the account is issued, the difference is included in the "financial expenses-exchange gains and losses" according to the foreign exchange quotation or the actual settlement interest rate of the day.

For example, on May 15, the USD account received USD 65,438+million (exchange rate 6.2 194).

Debit: bank deposit-USD 62 1940

Loans: accounts received in advance, etc. 62 1940

The exchange rate (median rate) on May 3rd1day is 6. 156.

Because accounting statements are needed at the end of the period, exchange gains and losses should be adjusted.

Debit: financial expenses-exchange gains and losses 6430[65438+ million *(6.2 194-6. 156)]

Loan: Bank deposit-$6,430.

Do the rest yourself according to the above ideas.
