A currency transaction report (CTR) is a report that U.S. financial institutions are required to file for each deposit, withdrawal, exchange of currency, or other payment or transfer, by, through, or to the financial institution which involves a transaction in currency of more than $10,000. Used in this context, currency means the coin and/or paper money of any country that is designated as legal tender by the country of issuance. Currency also includes U.S. silver certificates, U.S. notes, Federal Reserve notes and official foreign bank notes.
