Yen Gains on BOJ Rate Hike Bets; Pound Steady Amid Cooling UK Inflation

The Japanese yen strengthened on Wednesday amid growing expectations of a Bank of Japan (BOJ) rate hike, while the pound remained stable as cooling UK inflation offered some relief. Markets, however, treaded cautiously ahead of U.S. inflation data expected to influence Federal Reserve policy.

Investors await the December U.S. Consumer Price Index (CPI) report, which is anticipated to show a 0.2% rise in core prices. A higher figure could reduce chances for Fed rate cuts, intensifying the global bond sell-off and supporting the U.S. dollar.

In Japan, the yen rose 0.5% to 157.15 per dollar as BOJ Governor Kazuo Ueda signaled potential rate hikes if economic and price conditions improve. This followed Deputy Governor Ryozo Himino's remarks about debating rate adjustments at next week's meeting. Japanese two-year government bond yields hit multi-month highs, adding to yen strength.

Mizuho’s Jordan Rochester noted that strong CPI, rising wages, and higher oil prices in Japan make a rate hike more plausible. He also highlighted the market's sensitivity to next week's BOJ policy meeting and geopolitical risks, such as former U.S. President Trump's upcoming inauguration.

Meanwhile, in the UK, inflation slowed more than expected, with core measures falling sharply. This prompted speculation about a Bank of England rate cut in February. British bond yields dropped sharply, providing some support to the pound, which traded flat at $1.2205. Analysts observed that easing gilt yields helped stabilize sterling after last week's sell-off triggered economic concerns.

Other currencies, including the euro ($1.0302), Swiss franc (0.9119 per dollar), and Australian dollar ($0.6197), remained steady in quiet trading ahead of U.S. inflation data.

Traders remain focused on upcoming global events, with BOJ and Fed policies set to drive market sentiment.
