The Current Account is the headline part of Swiss balance of payments statistics (records of cross-border money flows). The Swiss National Bank (SNB) compiles it under BPM6 (an IMF global manual), with series back to 1983.
It covers transactions between residents (people and firms in Switzerland) and non-residents during 1 quarter, not domestic trade or asset stocks (point-in-time holdings). It sums goods, services, primary income (work and investment pay) and secondary income (transfers without return). Sources are SNB surveys, Federal Customs Administration trade data and SFSO inputs under the National Bank Act.
