Global Markets Await BoJ’s Interest Rate Decision December 2025

Markets are closely watching the Bank of Japan (BoJ) as it prepares to announce its interest rate decision tomorrow, Friday. This meeting is regarded as one of the most significant of the year, as Japan seems ready to change its monetary policy after years of maintaining ultra-loose measures. Investors will closely examine not only the decision itself but also the tone and language of the Bank of Japan's statement, as these could influence expectations for the months ahead, even if the central bank decides to keep interest rates steady, which is widely anticipated.

Why a Rate Hike Is Expected?

Inflation in Japan has continued to exceed the BoJ's target for longer than expected, signaling mounting pressure on the central bank to reconsider its ultra-accommodative stance. Wage growth has also shown clear improvement—a key factor in assessing whether higher inflation will persist.

Additionally, the recent weakness of the Japanese yen has raised import costs, directly affecting household purchasing power. As a result, the BoJ may view a gradual move toward a less accommodative policy as necessary to stabilize the currency and curb excessive market volatility without shocking the broader economy.

Global Significance of Japan's Monetary Policy

Japan remains the last major economy operating with an ultra-expansionary policy, making the yen a major funding currency and Japanese capital a significant driver of global liquidity. Any sign that the BoJ tolerates higher inflation or a weaker yen can trigger shifts in bond and currency markets worldwide. Therefore, tomorrow's focus extends beyond the interest rate decision to the BoJ's perceptions of inflation trends and wage growth dynamics.

Widening Interest Rate Gap with the U.S. and the Return of Carry Trades

The interest rate differential between Japan and the United States remains a critical topic. Following the Federal Reserve's recent rate cuts, Japanese rates remain far lower. The BoJ has signaled that this quarter may be its last under the current ultra-loose policy, potentially encouraging investors to borrow yen at low rates and invest in higher-yielding U.S. assets. This dynamic could increase capital outflows from Japan, exert continuous pressure on the yen, and complicate the BoJ's delicate balance between currency stability, financial conditions, and domestic growth.

What Markets Will Watch After the Announcement

Beyond the headline decision, markets will focus on forward guidance, inflation assessments, wage commentary, and any hints of Japan gradually aligning with global monetary norms. Such signals could significantly affect the yen and global bond yields. With the U.S. maintaining relatively high rates, the divergence between the two central banks remains a key factor shaping global capital flows.

Technical Outlook: USD/JPY

From a technical perspective, the USD/JPY pair on the daily chart is currently trading within a descending triangle following a strong upward trend. Successive lower highs are forming against a clear horizontal support zone between 154.50 and 155.00. A decisive break below this support could open the door to a deeper correction toward 153, then 151. Conversely, a breakout above the triangle's upper trendline and sustained trading above it could reignite bullish momentum, pushing the pair toward previous highs near 157–158. The Relative Strength Index (RSI) is hovering near neutral 50–55, indicating a lack of clear momentum at present.
