TOMORROW COULD BE THE MOST VOLATILE DAY FOR MARKETS THIS MONTH. 2 events are happening together, and both could cause extreme movements. The first one is the BOJ interest rate decision with almost certainty of a rate hike. But what BOJ thinks of future decisions will impact the markets. If the BOJ hints at aggressive tightening, USD/JPY could dump, and the risk of the yen carry trade unwind will go up. The 2nd one is triple-witching expiration with $6.2 Trillion in options expiry. If the market stays weak ahead of this options expiry, it could add further downside volatility.
