BTC Defies Yen Strength as USD/JPY Falls Below 156.50

The USD/JPY currency pair fell below 156.50 on September 30, 2026, as the Japanese yen surged in response to weak factory data.

Finance Minister Satsuki Katayama stated that a strong yen is 'a problem' and that Japan is coordinating with the US on foreign-exchange markets.

Despite high U.S. Treasury yields making the medium-term outlook bullish for USD/JPY, the short-term market picture is being driven by intervention concerns, end-of-period flows, positioning for upcoming U.S. data, and residual hawkish Bank of Japan signals.

BTC, however, is holding firm in the $83,000-$84,000 range, avoiding sharp selloffs often associated with yen strength.
