The Japanese Yen (JPY) weakened on Tuesday, with USD/JPY trading around 157.95, up 0.49% on the day, following a sharp rebound last week that was driven by coordinated intervention from Japanese and US authorities in the foreign exchange market [1]. Japan's Ministry of Finance confirmed the intervention, with Finance Minister Satsuki Katayama stating that authorities would not hesitate to intervene again if necessary. US Treasury Secretary Scott Bessent also indicated Washington's readiness to cooperate in future interventions, and US President Donald Trump described the move as 'a signal of friendship.' Bloomberg estimates that Japan spent around $34 billion on last week's intervention [1].
Despite these efforts, market focus has shifted back to Japan's fiscal outlook, with the ruling Liberal Democratic Party (LDP) backing a proposal to temporarily reduce the food consumption tax from 8% to 1% starting in April 2027, alongside approximately ¥600 billion in annual cash transfers for low- and middle-income households. The lack of a clearly defined funding mechanism for these measures has raised investor concerns, putting renewed pressure on the Yen [1]. The Bank of Japan's recent policy rate hike to 1% in June has not closed the interest rate gap with other major economies, continuing to support carry trades and providing a tailwind for USD/JPY [1].
Market sentiment has been influenced by geopolitical developments, with hopes of peace talks between the US and Iran leading to a moderate improvement in risk appetite. However, contradictory statements persist, as US President Donald Trump called it the 'last chance' for Iran to reach a deal, while Tehran denied any talks with the US [2]. Investors are also awaiting key US labor market data, including the JOLTS report and Friday's Nonfarm Payrolls (NFP), with economists expecting the US economy to add 83K jobs in July after 57K in June, and the unemployment rate to rise to 4.3% from 4.2% [1]. Stronger-than-expected data could reinforce expectations of a Federal Reserve rate hike in September, potentially supporting the US Dollar further [1].
The US Dollar was the strongest against the Japanese Yen among major currencies on Tuesday, gaining 0.47% against JPY, while showing marginal losses against the Swiss Franc (CHF) and other majors [2]. Technical analysis from MUFG suggests that Yen support from intervention is seen as temporary, with USD/JPY downside limited and US intervention expected to remain relatively small in scale [1]. Meanwhile, UOB analysts note that the US Dollar Index has shifted to a downside bias after failing to break above the weekly Ichimoku cloud and plunging below the 55-week EMA, but expect any decline to remain contained within the 97.63/101.64 range [3].
CONCLUSION
The Japanese Yen's recent weakness follows a brief rebound from coordinated intervention, but concerns over Japan's fiscal outlook and persistent interest rate differentials continue to pressure the currency. While intervention provided temporary support, analysts and technical indicators suggest limited downside for USD/JPY, with market attention now focused on upcoming US labor data and potential Fed policy moves. The US Dollar remains strong against the Yen, but broader downside risks for the Dollar Index are noted within a defined range.
