Jumpstarting an International Currency

This paper asks how a currency achieves international status — moving from zero to positive cross-border use — and whether deliberate central bank policy can accelerate that transition. The authors focus on the People’s Bank of China (PBoC) swap lines signed between 2009 and 2018, which extended RMB-denominated lender-of-last-resort credit to foreign central banks for the stated purpose of supporting RMB-denominated trade finance and settlement.

The empirical analysis combines two datasets. The first covers every RMB swap line agreement the PBoC signed with a foreign central bank (38 countries by 2018), compiled from PBoC news releases and validated against counterparty communications, treated as a staggered binary absorbing treatment. The second is monthly SWIFT data on cross-border payment message values (October 2010 – October 2018), disaggregated by currency and message type (payment orders MT103/MT202 and trade-finance messages MT400/MT700). The working sample, after excluding financial centre hubs, sanctioned countries, pre-sample treated countries, and small economies, covers 114 countries with 11,058 observations, of which 21 are treated during the sample period.
