The Japanese Yen (JPY) oscillates in a narrow band against its American counterpart during the Asian session on Friday and remains close to a nine-month low, touched the previous day. Japan's Prime Minister Sanae Takaichi on Wednesday expressed her administration's preference for interest rates to stay low and asked for close coordination on policy with the Bank of Japan (BoJ). This further cooled market expectations that an interest-rate hike is coming soon and has been a key factor behind the JPY's relative underperformance.
Traders, however, still see a 24% chance of a BoJ rate hike move in December and around 46% odds for an increase by January. Furthermore, the recent decline in the JPY prompted Japan's Finance Minister Satsuki Katayama and Economy Minister Minoru Kiuchi to issue a warning on currency movements, fueling intervention fears. This, along with the risk-off impulse, might hold back the JPY bears from placing aggressive bets, which, along with the prevalent US Dollar (USD) selling bias, caps the upside for the USD/JPY pair.

This week's breakout through the 154.45-154.50 horizontal barrier was seen as a key trigger for the USD/JPY bulls. Moreover, oscillators on the daily chart are holding comfortably in positive territory and are still away from being in the overbought zone. However, repeated failures to find acceptance above the 155.00 psychological mark warrant some caution before positioning for any further appreciating move. Spot prices might then climb to the 155.60-155.65 intermediate hurdle and eventually aim to reclaim the 156.00 round figure.
On the flip side, any further weakness could be seen as a buying opportunity and find decent support near the 154.00 mark. A convincing break below the said handle, however, might prompt some technical selling and drag the USD/JPY pair to the 153.60-153.50 region en route to the 153.00 round figure. The latter should act as a key pivotal point, which, if broken, might shift the bias in favor of bearish traders and pave the way for a slide towards the 152.15-152.10 area.
The Japanese Yen (JPY) is one of the world’s most traded currencies. Its value is broadly determined by the performance of the Japanese economy, but more specifically by the Bank of Japan’s policy, the differential between Japanese and US bond yields, or risk sentiment among traders, among other factors.
One of the Bank of Japan’s mandates is currency control, so its moves are key for the Yen. The BoJ has directly intervened in currency markets sometimes, generally to lower the value of the Yen, although it refrains from doing it often due to political concerns of its main trading partners. The BoJ ultra-loose monetary policy between 2013 and 2024 caused the Yen to depreciate against its main currency peers due to an increasing policy divergence between the Bank of Japan and other main central banks. More recently, the gradually unwinding of this ultra-loose policy has given some support to the Yen.
Over the last decade, the BoJ’s stance of sticking to ultra-loose monetary policy has led to a widening policy divergence with other central banks, particularly with the US Federal Reserve. This supported a widening of the differential between the 10-year US and Japanese bonds, which favored the US Dollar against the Japanese Yen. The BoJ decision in 2024 to gradually abandon the ultra-loose policy, coupled with interest-rate cuts in other major central banks, is narrowing this differential.
The Japanese Yen is often seen as a safe-haven investment. This means that in times of market stress, investors are more likely to put their money in the Japanese currency due to its supposed reliability and stability. Turbulent times are likely to strengthen the Yen’s value against other currencies seen as more risky to invest in.
