Bank Indonesia, the nation’s central bank, said it would soon appoint several domestic lenders to assist exporters and importers interested in using the new currency swap arrangement with China.

BI is preparing the criteria for lenders to become “agent banks” for transactions in which Indonesian and Chinese traders will convert rupiah directly to the yuan and vice versa, without having to use the US dollar.

“For monitoring and supervisory purposes, only a few banks will be chosen to serve as agent banks. The People’s Bank of China will also do the same [with banks in China],” BI Senior Deputy Governor Miranda Goeltom said on Wednesday.

“We hope to implement this a month from now.”

BI and the PBOC on Monday signed a swap facility agreement worth 100 billion yuan ($14.6 billion). A key part of the deal will provide BI with an emergency fund to defend the rupiah against depreciation, but the arrangement is also aimed at stimulating bilateral trade and investment.

“The swap agreement can only be used for real trade and investment, not for trading financial products,” Goeltom said.

Direct rupiah-yuan transactions are not new, but they are small relative to the overall value of trade between Indonesia and China trade, according to BI data. Indonesia last year used rupiah to pay for just $105.9 million of the $14.99 billion worth of goods it imported from China.
