The Treasury International Capital (TIC) system is a set of reports released by the U.S. Treasury Department that provides information on cross-border investments in U.S. securities. The TIC reports provide data on foreign purchases and sales of U.S. Treasury bonds, notes, bills, and other securities, as well as U.S. purchases and sales of foreign securities.The TIC system has two main reports: the TIC Long-Term Purchases and Sales report, which provides data on transactions in long-term securities (maturity greater than one year), and the TIC Flows report, which provides data on transactions in all securities, including short-term securities. Both reports are released on a monthly basis.The TIC reports are important indicators of the level of foreign demand for U.S. securities, and can provide insight into the level of foreign investment in the U.S. economy. The reports can also be used to track changes in the level of foreign investment in U.S. securities over time, and to identify trends in foreign investment.It is important to note that TIC data are not comprehensive, as it only covers transactions reported to the Federal Reserve Bank of New York, and it does not include transactions made by foreign central banks or sovereign wealth funds.
