The Russian government has recently announced it will issue nearly $1 billion equivalent in state bonds, but denominated not in US dollars as is mostly the case. Rather it will be the first sale of Russian bonds in China's yuan.
While $1 billion may not sound like much when compared with the Peoples' Bank of China total holdings of US Government debt of more than $1 trillion or to the US Federal debt today of over $20 trillion, it's significance lies beyond the nominal amount. It's a test run by both governments of the potential for state financing of infrastructure and other projects independent of dollar risk from such events as US Treasury financial sanctions.
Russian Debt and China Yuan
Since the August 1998 sovereign default triggered by the West, Russian state finances have been prudent to almost a fault. The size of the national government debt is the lowest of any major industrial country, a mere 10.6% of GDP for the current year. This has enabled Russia to withstand the US financial warfare sanctions imposed since 2014, and forced the country to turn elsewhere for their financial stability. That "elsewhere" is increasingly called the Peoples' Republic of China.
