FIMA Repo Backstop

179.先救日元再救长债，“救火队长”贝森特在走一条怎样的钢丝？ treats the Fed’s foreign official repo facility as a potential FIMA Repo Backstop: foreign central banks can raise dollar liquidity against Treasury collateral instead of selling Treasuries outright. In the episode, Scott Bessent / 贝森特 calls for expansion of the facility after U.S.-Japan Currency Intervention because Japan defending the yen by selling Treasuries would worsen U.S. financing pressure.

Key Claims

• FIMA Repo can separate currency-defense liquidity from forced Treasury sales.
• The tool protects Treasury-market demand as much as it helps the foreign central bank.
• Expanding the facility would make the Federal Reserve more visibly part of Treasury-market and currency-stability management.
• The backstop is useful only if foreign official holders trust access, terms, and political continuity.

Connections

• Federal Reserve, U.S. Treasury, Bank of Japan, and Japan - institutions connected by the facility in this source.
• Treasury Demand Substitution, Bessent Impossible Triangle / 贝森特不可能三角, and Policy Ambiguity As Market Tool - policy logic around the facility.
• Yen Carry Trade, Currency Risk, and Central Bank Independence - risks and governance issues the episode extends.
