The Japanese Yen weakened sharply against the US Dollar, with USD/JPY climbing above 163 for the first time in nearly 40 years, according to FX Street citing Societe Generale. The pair shows support around 162.20 and faces resistance near 164.40 as it remains in breakout territory.

FX Street referencing MUFG noted that the current levels, last seen in 1986, coincide with unusually low volatility. This environment challenges the Ministry of Finance's rationale for market intervention. Meanwhile, inflationary pressures and political factors are increasing, although contagion effects in Japanese bonds remain limited.

This movement underscores ongoing challenges for Japan’s monetary policy amid a persistently weak yen, which impacts import costs and export competitiveness in the FX and equities markets.
