U.S.-Japan intervention revives yen carry trade fears for bitcoin

The U.S. and Japan's intervention in the foreign exchange market has revived fears of a yen carry trade, but bitcoin's correlation with the yen suggests that broad U.S. dollar strength may be the bigger risk.

Why it matters

The coordinated intervention by the U.S. and Japan in the foreign exchange market has significant implications for the crypto market, particularly for bitcoin.

Imagine you're playing a game where you have to guess how much money people will spend on something. If people think the yen is going to get stronger, they might sell their yen and buy something else, like bitcoin. But, if people think the U.S. dollar is going to get stronger, they might sell their yen and buy U.S. dollars instead. This can make it harder for people to buy bitcoin because they're selling their yen to buy U.S. dollars. It's like a big game of musical chairs, and the U.S. dollar is the chair that everyone wants to sit in.

Analysis

A $60B Vote of Confidence

The U.S. and Japan's coordinated intervention in the foreign exchange market has sent shockwaves through the financial markets, reviving fears of a yen carry trade. The intervention, which saw the U.S. join Japan in buying yen to weaken the currency, has sparked concerns that a stronger yen will pressure crypto. However, a closer look at the data suggests that the correlation between bitcoin and the yen is not as straightforward as it seems.

Bitcoin's 52-week rolling correlation with USD/JPY had hit -0.90, suggesting that BTC was actually falling alongside a weakening yen, which is the opposite of carry-trade logic. Analysis shows that it was more likely broad U.S. dollar strength, not the yen, that was driving the price action. Japanese bond yields are still surging regardless of the announcement, with the 30-year yield approaching 4%, while bitcoin has remained relatively flat above $63,000.

The BOJ held rates at 1% last week, while Governor Kazuo Ueda's flagged AI demand and yen weakness as the two factors pushing inflation above 2%. Different this time? However, with everyone expecting bitcoin to fall alongside a strong yen, CoinDesk analysis shows the opposite. Bitcoin's correlation with the yen suggests that broad U.S. dollar strength may be the bigger risk.

The coordinated intervention by the U.S. and Japan in the foreign exchange market has significant implications for the crypto market, particularly for bitcoin. The intervention has revived fears of a yen carry trade, but the data suggests that the correlation between bitcoin and the yen is not as straightforward as it seems. Broad U.S. dollar strength may be the bigger risk, and investors should be cautious of the potential impact on the crypto market.

Key points

  • Japanese bond yields are still surging regardless of the announcement, with the 30-year yield approaching 4%.
  • Bitcoin has remained relatively flat above $63,000 despite the intervention.
The Upside

If the coordinated intervention by the U.S. and Japan in the foreign exchange market continues to drive broad U.S. dollar strength, it could lead to a decrease in the price of bitcoin. However, if the yen continues to weaken, it could lead to an increase in the price of bitcoin.

The Downside

If the coordinated intervention by the U.S. and Japan in the foreign exchange market continues to drive a stronger yen, it could lead to a decrease in the price of bitcoin. Additionally, if the U.S. dollar continues to strengthen, it could lead to a decrease in the price of bitcoin.
