GBP/JPY impressive 155 pip rally hits a wall at daily resistance

• GBP/JPY off to an impressive start om the week so far.
• Bulls have met a critical resistance area, but a new catalyst may have to wait until the end o the week in UK data.

GBP/JPY has been one of the best performing crosses, with the bulls rallying some 155 pips to a previous resistance level.

At the time of writing, GBP/JPY is trading at 135.81 having rallied from 134.33 the low to a high of 135.90.

Cable has eked out a 0.75% advance on the day so far despite worsening tones withing the Brexit debacle.

However, it is worth noting that the pound is probably also benefitting from a robust euro as well.

The UK exiting the lockdown measures could also be a supportive factor.

It should be noted that the changes in consumer spending behaviour and general social distancing will prevail for a long time to come yet.
