Understanding the Carry Trade: How Japan's Low Rates Drive Global Markets

The yen carry trade (borrow cheap yen, invest in higher-yielding assets) is one of the largest trades in global finance. BOJ rate at 0.5% vs Fed at 4.5% creates a 4% carry. Estimated $1T+ in carry trade positions globally. When carry trades unwind (yen strengthens), global markets destabilize. The August 2024 yen spike triggered a global selloff. As BOJ slowly normalizes rates, the unwinding risk grows. This is a systemic risk that few investors adequately hedge.
