The People's Bank of China Launches FIMA RMB Repo Facility: Building a Bridge on the Path to Reserve Currency Status

Background

In June 2025, the People's Bank of China announced the launch of the "Foreign Central Bank Type Institution RMB Repurchase Tool" (FIMA RMB Repo). The logic is straightforward: it allows foreign central banks (including national central banks, international financial organizations, and sovereign wealth funds) to borrow RMB from the PBOC using Chinese government bonds, central bank bills, and policy finance bonds as collateral, with terms ranging from 7 days to 3 months.

At first glance, this appears merely to be a liquidity provision tool—similar to the Federal Reserve's Dollar Swap Line. But within the global financial system, this move carries implications far beyond its surface appearance.

Why This Matters

Historical Context: The Triffin Dilemma

In 1960, Belgian economist Robert Triffin posed the famous "Triffin Dilemma": for a country to maintain reserve currency status, it must continuously supply that currency to the global economy (via trade deficits), yet this simultaneously undermines that currency's credibility (because the central bank's gold reserves are insufficient to cover all currency in circulation).

The United States has been trapped in this dilemma since 1944. Today, US dollar reserves still account for 58% of global central bank holdings—not because the dollar's commodity value remains unchanged, but because of:

1. Deep market depth: The US Treasury market is the world's largest, with continuous tradability 2. Liquidity swap networks: The Federal Reserve has standing swap agreements with major central banks worldwide, guaranteeing access to dollars on demand 3. Dollar settlement networks: SWIFT, Fedwire, and CHIPS make dollars omnipresent in global clearing systems 4. Political credibility: US national strength and institutional stability

For the RMB to become a mainstream reserve currency, it must advance across all four dimensions. The PBOC's move targets the "liquidity swap networks" component.

Technical Dimensions: The Significance of Repo Tools

The repo tool appears simple but solves a fundamental question: Why should foreign central banks hold RMB?

If you were the Bank of Japan or the Swiss National Bank, you might hold RMB for reasons such as: - Hedging China-related risk exposure - Conducting trade settlement - Diversifying reserve assets

But if you hold 10 billion RMB and one day need cash (say, for emergency liquidity), you'd ask: "Can I quickly convert RMB into dollars or other liquid assets?"

If the answer is "difficult and at a discount," the cost of holding RMB becomes prohibitively high.

The FIMA repo tool directly answers this question: Yes, you can convert RMB assets into cash within 7 days. Moreover, the rate is "7-day reverse repo rate plus a spread," meaning pricing is transparent and you won't face sudden policy changes. This fundamentally alters foreign central banks' risk assessment of RMB holdings. The liquidity risk of holding RMB has decreased.

Deeper Logic: Infrastructure Competition

The dollar's 58% share of global reserves isn't because the US is wealthier than other nations, but because America built complete currency infrastructure 80 years ago. After the Bretton Woods system collapsed, the US maintained this infrastructure, including:

1. Clearing systems: SWIFT, Fedwire (the US domestic bank clearing system) 2. Liquidity provision: The Federal Reserve's dollar swap lines spanning the globe 3. Bond markets: US Treasury market daily trading volume exceeds $800 billion 4. Banking networks: Clearing banks in New York controlling global dollar flows

For the RMB to upgrade its international status, it cannot rely solely on "economic scale" or "political influence"—it requires complete infrastructure. This infrastructure includes:

• Clearing hubs: China launched the Cross-Border Interbank Payment System (CIPS) last year, paralleling SWIFT
• Market depth: Gradual opening of the Chinese bond market
• Liquidity provision: The offshore RMB market in Hong Kong (CNH), and now the FIMA repo tool

Strategic Intent

Short-term: Attracting Foreign Capital

The immediate effect of the FIMA repo tool is providing RMB liquidity to foreign central banks. This may attract more foreign central banks to increase RMB reserves. Central banks in Japan, Switzerland, Singapore and others might increase holdings due to reduced liquidity risk.

Medium-term: De-dollarization in Regions

With increased RMB reserves, countries in Asia, Africa, and the Middle East may become more willing to conduct regional trade settlement in RMB. This weakens the dollar's monopoly in these regions.

Long-term: Diversification of Reserve Currencies

In the coming years, if RMB reserves rise to 10-15% of global central bank assets (currently around 2%), the structure of the global financial system will change. Central banks worldwide will face genuine "reserve diversification" choices rather than forced reliance on the dollar. This reduces America's ability to export inflation or deflation globally through monetary policy.

Risks and Limitations

Political Credibility

The FIMA repo tool's effectiveness depends on foreign central banks believing the RMB won't depreciate more than 5% within 3 months, and trusting that China won't suddenly change policy. This requires a long-established international reputation. Any geopolitical crisis (such as escalated military threats toward Taiwan) could destroy this trust.

Market Depth

US Treasury market average daily trading volume exceeds $800 billion. Though China's bond market opening has increased, average daily trading volume of foreign investor participation is under $20 billion. The gap in liquidity depth means large-scale RMB sales could face insufficient buyer demand.

Capital Controls

China still maintains certain controls on cross-border capital flows. This means even if foreign central banks hold RMB, they cannot freely redirect it to other uses. This reduces the RMB's "universality."

Historical Parallels

This move recalls the monetary cooperation mechanisms European central banks established in the 1960s-1970s to challenge dollar hegemony. Ultimately, the euro was born in 1999, becoming the world's second-largest reserve currency.

But the euro's success was built on something the RMB currently lacks: European political union and a common institutional framework. For the RMB to follow the euro's path, it requires not just China's efforts but also the willingness of regional countries to achieve deep financial integration—a difficult proposition in today's geopolitical environment.

Conclusion

The FIMA RMB repo tool is not an isolated policy but rather one move in China's long-term strategy to establish the RMB's international monetary status. The value of this move lies in:

1. Reducing the liquidity costs for foreign central banks holding RMB 2. Signaling globally that "RMB is liquid and convertible" 3. Forming synergy with policies like CIPS and opening of the Chinese bond market

But it will not overnight transform the global financial landscape. Reserve currency status is built over decades through infrastructure accumulation, credibility, and scale. The RMB still has a long journey ahead.
