USD/JPY Under Pressure as Yen Regains Market Favor

The Japanese yen strengthened beyond the 154 level against the US dollar during Tuesday's trading (September 8), reaching its strongest position since February. This sharp appreciation extends the yen's recovery from the intense pressure that had previously driven it to its weakest level in roughly four decades back in July. Sentiment has shifted as investors ramp up expectations for policy tightening by the Bank of Japan.

The yen's rally is supported by several factors, including the unwinding of carry trades, the potential repatriation of funds by Japanese investors from abroad, and mounting political pressure on authorities to take decisive action to ensure currency stability. The yen's strengthening has prompted investors who previously borrowed the currency at low costs to consider closing out their positions.

Expectations regarding the Bank of Japan have also turned increasingly hawkish. Markets anticipate that the central bank could raise interest rates at its September meeting. An economic advisor to Prime Minister Sanae Takaichi even predicts that the BOJ might hike rates this month and implement further tightening no later than January of next year.

This shift in expectations is significant, given that Takaichi's administration was previously known to favor loose monetary policy. However, the extreme weakness of the yen and the risk of imported inflation have brought the need for tighter policy into sharper focus.

Additional support stems from Japanese wage data. Wage growth recorded its fastest pace since 1997, reinforcing the view that domestic wage pressures are becoming increasingly sustainable. Rising wages are a key factor monitored by the BOJ, as they can sustain inflation and provide the central bank with room to proceed with the normalization of monetary policy.
