The Japanese Yen (JPY) continued its decline on Tuesday, with the USD/JPY pair reaching session highs at 162.70 during the European trading session, just below the 40-year high of 162.84, which is seen as a potential threshold for Tokyo intervention [1]. The Yen's weakness persists despite a moderately softer US Dollar, as rising oil prices and ongoing interest rate divergences between the Bank of Japan (BoJ) and other major central banks exert downward pressure on the currency [1][2]. MUFG’s Lee Hardman highlighted that the negative energy price shock, driven by rising Brent prices linked to US–Iran tensions and Houthi threats to shipping, remains a significant headwind for the Yen. Since the US-Iran conflict began in late February, only the Swedish krona and Swiss franc have weakened more than the Yen [2].
On the policy front, the Japanese government has approved an annual economic and fiscal policy plan, though it did not include a decision on Prime Minister Takaichi’s election pledge to suspend the sales tax on food. The government is expected to determine its stance by early August [2]. Additionally, the government approved a growth strategy targeting domestic investment of more than JPY370 trillion through March 2041, aiming to lift nominal GDP to nearly JPY1,100 trillion [2]. The final policy document emphasized the BoJ’s autonomy in monetary policy, stating the importance of conducting appropriate policy to achieve 'stable price increases.' This clarification has eased some investor concerns about potential government restrictions on BoJ tightening, which had previously contributed to Yen selling [2].
Despite BoJ officials reiterating their commitment to further tightening, investors remain skeptical that rates will rise much above 1.25% in the near term, as higher rates could threaten Japan’s economic growth objectives [1]. This skepticism leaves the Yen vulnerable to carry trades, where investors borrow low-yielding currencies like the Yen to invest in higher-yielding assets, further fueling JPY-short positions [1].
Looking ahead, market participants are focused on Japan’s June National Consumer Prices Index (CPI) figures, which are expected to show a mild uptick after soft readings in the previous two months. A positive surprise in inflation data could renew pressure on the BoJ to hike rates and potentially support the Yen, at least temporarily [1].
CONCLUSION
The Japanese Yen remains under significant pressure due to rising energy prices, persistent interest rate differentials, and ongoing policy uncertainty. While recent government actions have eased some concerns about BoJ autonomy, market participants are closely watching upcoming inflation data for signs of potential policy shifts. The Yen’s vulnerability is likely to persist unless there is a notable change in monetary or fiscal policy direction.
