Why is a Bank of Japan rate hike a potential "Black Swan"? Look at the math. 🦢📉 Traders borrowed Yen to buy USD assets. When the Yen strengthens, the value of that debt in dollars explodes upward. You don't need your stocks to crash to get wiped out; you just need the currency to move against you. When the debt gets heavier than the assets, margin calls force a global sell-off. #Forex #USDJPY #MarketCrash #Investing #BankofJapan
