GBP/JPY eased on Thursday as the Yen strengthened on intervention warnings from Japanese officials, with USD/JPY trading near 160.00. GBP/JPY was around 215.27 at the time of writing, down from an intraday high of 215.74.
Japan’s Finance Minister Satsuki Katayama said past FX interventions “had an influence every time” and that Japan has “a free hand over FX intervention”. She added that deputies in the US and Japan are in close contact on foreign exchange.
Falls in GBP/JPY were limited as higher oil prices, linked to supply issues in the Strait of Hormuz, weighed on the Yen due to Japan’s reliance on imported energy. The strait is under a dual blockade by the US Navy and Iran, with tensions rising.
US President Donald Trump said he ordered the Navy to “shoot any boat putting mines in Hormuz”. The Washington Post, citing a Pentagon assessment, reported clearing mines could take up to six months.
On the daily chart, GBP/JPY remains above the 50-day, 100-day, and 200-day SMAs. RSI is 62 and MACD is above zero; support sits at 213.50, then 212.00–211.50, with the 200-day SMA at 206.25.
We’re seeing the Japanese Yen gain some ground due to fears of currency intervention, similar to the verbal warnings we saw throughout 2025 when USD/JPY last pushed toward 160. This is causing a slight dip in GBP/JPY, but the bigger picture remains tilted towards a stronger pound. This short-term pullback presents an opportunity, not a trend reversal.
The threat of intervention from Japanese authorities is real, and we have to respect it. Looking back, we saw the Ministry of Finance step in forcefully in 2022 and again in 2024 when the yen weakened past similar psychological levels. Current data shows Japan’s foreign currency reserves have been drawn down by over $50 billion in the first quarter of 2026, signaling they are prepared to act again.
However, the fundamental case against the yen is strengthening due to the unresolved tensions in the Strait of Hormuz. With those supply disruptions from last year continuing, Brent crude futures for June delivery are now trading above $95 a barrel, a 15% increase since the start of the year. As a major energy importer, this sustained high price weighs heavily on Japan’s economy and its currency.
This energy-driven inflation is forcing central banks apart, which is key for this currency pair. The latest UK Consumer Price Index came in at a stubborn 3.5%, leading markets to price in a 60% chance of a Bank of England rate hike by August. Meanwhile, Japan’s core inflation has stalled near 2.2%, giving the Bank of Japan every reason to delay further tightening.
For derivatives traders, this means buying call options on GBP/JPY on any dips could be a smart move. It allows us to capture the potential upside from the strong underlying trend while capping our risk in case of a sudden intervention. Implied volatility for one-month options has jumped to over 12%, reflecting this exact tension between fundamentals and policy threats.
The technical charts still support a bullish stance as long as we hold above key levels. The area between 212.00 and 213.50, which includes the 50-day moving average, is the first major support zone to watch. A successful test of this level would be a strong signal to add to long positions.
