From the IMF's description:
Balance of Payments Statistics summarizes, for a specific period, the economic transactions of an economy with the rest of the world. It reports total goods, services, factor income, and current transfers an economy receives from or provides to the rest of the world as well as capital transfers and changes in each economy's external financial claims and liabilities.
The BOP database contains time series data from 1948. The Web interface allows subscribers to browse the database, select series of interest, display the selected series in a spreadsheet format, and save the selected series for transfer to other software systems such as Microsoft Excel®.
