The Japanese Yen (JPY) gains some positive traction during the Asian session on Thursday and stalls its modest pullback from a one-week top, touched against a broadly weaker US Dollar (USD) the previous day. Speculations that Japanese authorities would step in to stem any further weakness in the domestic currency offer some support to the JPY. Adding to this, expectations that the Bank of Japan (BoJ) could raise interest rates as soon as next month provide a modest lift to the JPY.
However, the prevalent risk-on environment, along with concerns about Japan's worsening fiscal position amid Prime Minister Sanae Takaichi’s pro-stimulus stance, acts as a headwind for the safe-haven JPY. The negative factor, to a larger extent, is offset by sustained USD selling, which continues to be undermined by bets for another interest rate cut by the US Federal Reserve (Fed) in December. This, in turn, should keep a lid on any meaningful recovery move for the USD/JPY pair.

The overnight move up faced rejection near the 100-hour Simple Moving Average (SMA), which is currently pegged near the 156.70 region and should act as a key pivotal point for the USD/JPY pair. A sustained strength beyond should allow spot prices to reclaim the 157.00 mark and climb further toward the 157.45-157.50 intermediate hurdle en route to the 158.00 neighborhood, or the highest level since mid-January, touched last week.
On the flip side, weakness below the overnight swing low, around the 155.65 region, should pave the way for deeper losses and drag the USD/JPY pair to the 155.00 psychological mark. A convincing break below the latter will be seen as a fresh trigger for bearish traders and set the stage for an extension of a one-week-old downtrend from the vicinity of the 158.00 round figure.
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.
