The British Pound has weakened against the Japanese Yen due to hawkish comments from Bank of Japan Governor Kazuo Ueda. At the time of writing, GBP/JPY is trading near a five-day low of 205.25.
Governor Ueda indicated that a December rate hike is still being considered, which increased market expectations. His comments led traders to increase the odds of a December 18-19 rate hike to 80%, up from 60% a week earlier.
Market Response To BoJ Governor’s Comments
Japan’s 10-year government bond yield surged above 1.85% following Ueda’s remarks, the highest since July 2006. Meanwhile, the UK’s Manufacturing PMI rose to 50.2 in November, the first time it surpassed 50 in over a year.
Despite this PMI increase, Sterling received limited support, showing ongoing business uncertainty. Traders are watching for upcoming remarks from a Bank of England policymaker and the Financial Stability Report.
The Bank of Japan has historically engaged in ultra-loose monetary policy to stimulate the economy. Recent decisions to unwind this policy have strengthened the Yen, reversing trends observed in previous years. This shift is partly due to rising Japanese inflation and wage expectations.
The Bank of Japan is signaling a clear shift in policy, with Governor Ueda’s comments suggesting a rate hike is likely at the December 18-19 meeting. We should now position for continued Yen strength against the Pound. This fundamentally alters the trading landscape for JPY pairs which has been dominated by a weak Yen for years.
Strategic Positioning For GBP/JPY
Given the increased probability of a sharp move, we are looking at options to position for a lower GBP/JPY. Buying put options on the pair offers a defined-risk way to profit from further Yen appreciation leading into the BoJ meeting. One-month implied volatility for GBP/JPY has surged past 14%, a level we haven’t seen since the policy shift back in the spring of 2025, reflecting market anticipation.
The broader market is already reacting to this potential shift away from the ultra-loose policies of the last decade. Looking at the latest CFTC data from last Friday, speculative net short positions on the Yen saw their most significant weekly decrease since the third quarter of 2025. This is happening as recent reports show major Japanese corporations are considering average wage increases of over 4.5% for 2026, a key factor for the BoJ.
While the UK’s manufacturing PMI finally climbing above 50 is a positive domestic sign, it is being overshadowed by the BoJ’s powerful monetary policy narrative. Sterling’s own fundamentals are taking a backseat as the interest rate differential between the UK and Japan is poised to narrow. Therefore, we see any strength in the Pound as a selling opportunity in the GBP/JPY pair for now.
This is a stark reversal from the 2022-2024 period when the wide policy divergence between the BoJ and other central banks made shorting the Yen a very crowded trade. We must now closely watch for any further guidance from either the BoJ or the Bank of England ahead of their mid-December meetings. The primary focus remains on the December 18-19 BoJ decision, which will be the main driver of this pair.
