The USD/JPY pair just posted a solid 0.5% jump and is now trading at 157.66. For crypto traders keeping tabs on macro movements, this kind of yen weakness matters—when the dollar strengthens against major fiat currencies, it often signals shifts in risk appetite across asset classes. The yen's depreciation tends to correlate with broader market sentiment, so watching these forex swings can give you early signals on how digital assets might react. Whether you're analyzing Bitcoin's correlation with dollar strength or tracking altcoin movements during macro volatility, understanding currency dynamics helps you stay ahead of the curve.
