April 8, 2021 - Written by Ben Hughes Despite hitting its best levels in over a year this week, the British Pound to Japanese Yen (GBP/JPY) exchange rate has plummeted since then, shedding most of the gains seen over the past month in a matter of days. A combination of factors are helping the previously weak Japanese Yen to capitalise against this week’s broad Pound weakness. Unless there is a shift of market sentiment over the coming day, the Pound could remain jittery unless next week’s UK growth data impresses investors. Due to strong currency movement and market sentiment, GBP/JPY has seen huge movements in recent weeks. Last week saw GBP/JPY surge from 151.17 to 153.08 - a massive gain of almost two Yen.
