Notes

Estimated foreign holdings of U.S. Treasury marketable and non-marketable bills, bonds, and notes reported monthly under the Treasury International Capital (TIC) reporting system. Holdings of Treasury bonds and notes are reported on TIC Fom SLT, "Aggregate Holdings of Long-Term Securities by U.S. and Foreign Residents," including preliminary SLT data for the most recent month. The data in this table are collected primarily from U.S.-based custodians. Since U.S. securities held in overseas custody accounts may not be attributed to the actual owners, the data may not provide a precise accounting of individual country ownership of Treasury securities.
