US Treasury proposal to buy Japanese yen

Does the proposal include a projected impact on the exchange rate? A $10 billion injection seems statistically insignificant relative to daily liquidity.
Swap lines are great for the spreadsheets, but the real impact is on the supply chain. If the yen doesn't stabilize, the cost of Japanese precision parts for US manufacturers will just keep climbing.
Calling this stabilization is a reach. This is a strategic lever to force the Bank of Japan's hand on interest rates.
The suggestion that the Treasury avoids direct intervention is a bit of a misconception. While unilateral support is rare, we have a long history of coordinated interventions, such as the 1985 Plaza Accord, to manage exchange rates.
it is a carry trade insurance policy.
The proposal specifically mentions executing these purchases via currency swap lines. This distinguishes the move from a standard market operation using reserves.
The yen has seen such massive swings in the last few months... it has been a total rollercoaster... this would act as a necessary circuit breaker!
