The recent unwinding of the JPY carry trade has led to a global sell-off in markets such as the S&P 500, VIX, and Nasdaq. This has caused volatility in the forex market as traders adjust their positions. The Japanese yen is often used in carry trades due to its low interest rates, but when this trade unwinds, it can lead to a rush to sell off risky assets. As a result, the S&P 500, VIX, and Nasdaq have all experienced downward pressure. Investors should closely monitor these developments to navigate the current market environment.
