Every one is given a deadline and checked against later coverage, and the score is published on the ledger — including the ones that miss.

• Awaiting deadline 45% Short-term Stabilization

  The coordinated intervention temporarily halts the yen's decline, leading to a period of relative currency stability. Japanese and US central banks maintain open lines of communication, preventing further speculative attacks while broader economic fundamentals remain unchanged.

• Awaiting deadline 30% Trade Policy Concession

The intervention is framed by both governments as a precursor to a broader trade deal, satisfying Trump's political goals.

• Awaiting deadline 15% Market Reversal and Speculative Attack

  Hedge funds and institutional investors interpret the intervention as a sign of underlying economic weakness in Japan, leading to a renewed and stronger sell-off of the yen. Despite Japanese efforts, the currency drops to new lows, forcing the Bank of Japan to raise interest rates prematurely, causing domestic recession fears.

• Awaiting deadline 10% Diplomatic Fallout and Coordination Breakdown

  Internal disagreements surface between the US Treasury and the Federal Reserve, with the latter opposing the intervention due to inflation concerns. This public discord undermines market confidence, leading to a chaotic currency swing. Japan feels sidelined by the US, prompting Tokyo to explore independent monetary strategies or closer ties with Asian partners.

  Watch for: Federal Reserve Chair Jerome Powell explicitly states that US domestic monetary policy remains independent of foreign exchange operations. · Japanese Finance Minister Suzuki announces a review of Japan's foreign reserve management strategy to reduce US dependency. · US and Japanese officials issue conflicting statements regarding the duration and purpose of the joint intervention.
