The Japanese Yen (JPY) attracts fresh buyers at the start of a new week as traders keenly await the highly-anticipated Bank of Japan (BoJ) rate decision on Friday. Market expectations for an imminent BoJ rate hike in December have risen recently amid a shift in rhetoric from Governor Kazuo Ueda. Moreover, inflation in Japan remains above the BoJ's 2% target, which, along with an improvement in the business confidence among major Japanese manufacturers, backs the case for further policy tightening. This, along with a weaker risk tone, underpins the safe-haven JPY.
However, worries about Japan's deteriorating fiscal condition, amid Prime Minister Sanae Takaichi's massive spending plan, might hold back the JPY bulls from placing fresh bets. The US Dollar (USD), on the other hand, languishes near a two-month low, touched last Thursday, in the wake of rising bets for two more rate cuts by the US Federal Reserve (Fed). This marks a significant divergence compared to hawkish BoJ expectations, which, in turn, drags the USD/JPY pair back below mid-155.00s during the Asian session and backs the case for a further depreciating move.

From a technical perspective, the USD/JPY pair has been struggling to move back above the 100-hour Simple Moving Average (SMA), and the subsequent slide favors bearish traders. However, positive oscillators on the daily chart suggest that any further decline is more likely to find decent support near the 155.00 psychological mark. A convincing break below the latter would turn spot prices vulnerable to accelerate the fall towards the monthly low, around the 154.35 area, en route to the 154.00 mark.
On the flip side, the 100-hour SMA, currently pegged at the 156.00 round figure, might continue to act as an immediate hurdle. Some follow-through buying beyond Friday's swing high, around the 156.10-156.15 region, might trigger a short-covering move and lift the USD/JPY pair to the 157.00 neighborhood. A sustained strength beyond the latter should pave the way for additional gains towards the 157.45 intermediate hurdle en route to a multi-month top, around the 158.00 neighborhood, touched in November.
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.
