Executive Summary
GBP/JPY trades at 210.75, meaning 1 GBP buys 210.75 JPY, having declined 0.62% over the past month and 0.33% over three months after peaking at 215.01 on February 4. The pair sits at the 86th percentile of its 52-week range (184.39–215.01), with spot marginally below both the 50d SMA (210.84) and 100d SMA (211.36) but well above the 200d SMA (207.05). The dominant bilateral narrative is a tug-of-war between the UK's +300bp carry advantage — under threat from a BoE trapped in stagflation — and the BoJ's active normalisation cycle with a ~70% probability of hiking to 1.00% on April 27-28. Both currencies face acute headwinds from the Iran conflict's energy shock, but the transmission differs fundamentally: GBP weakens via terms-of-trade deterioration and fiscal stress, while JPY weakens via catastrophic import cost inflation, creating a rare environment where the energy shock is roughly neutral for this specific pair. Our tactical stance is Bearish with Conviction 2: the BoJ hike catalyst and MoF intervention risk at USD/JPY 160 create asymmetric downside for GBP/JPY over 2-4 weeks, despite the pair's substantial carry buffer.
