Jakarta. Bank Indonesia has lowered the threshold for purchasing US dollars and other foreign currencies without supporting documentation from $25,000 to $10,000 per person per month, as part of efforts to support rupiah stability and strengthen oversight of foreign exchange transactions.

The new regulation will take effect on July 1, Governor Perry Warjiyo announced on Thursday following a meeting of the central bank’s Board of Governors.

“The reduction of the threshold for cash foreign exchange purchases against rupiah without underlying documents to $10,000 per customer per month will be implemented,” Perry said during a press conference in Jakarta.

Under the revised rules, individuals seeking to purchase more than $10,000 worth of foreign currency in a month must provide documentation explaining the purpose of the transaction.

Acceptable supporting documents may include requirements related to import financing, overseas travel expenses, education costs, investment activities, or other legitimate transactions that can be verified.

Bank Indonesia has also tightened regulations governing overseas transfers of foreign currency by lowering the threshold for transfers without supporting documentation from $50,000 to $25,000.

“That measure will also take effect on July 1, 2026,” Perry said.
