What's Behind the Rare US-Japan Yen Intervention?

Summary

Bloomberg TV covers the first US-Japan joint yen intervention in 15 years. Macro strategist Andre de Silva explains that the IMF three-day accounting rule made a second round of intervention unsurprising and that Friday's action was around $53 billion. Despite the intervention, the macro backdrop of interest-rate differentials remains unfavorable for the yen, so policy is aimed at slowing depreciation rather than reversing it. He also notes that a sustained move lower in dollar-yen could pressure Japanese equities due to portfolio biases toward financials and exporters.
