Before they called the lion share what you need to give to financial exchangers in City of London the 20% about but now brics nations deal without GBP UK.
It's not dedollarisation but de-GBP SATION.
retail will buy falling UK GBP because a lot brazil Indian and other brics nation people working in UK and they exchange their currency to GBP.
Also no more emerging market countries leaders and dictators who devalue their own currency against UK GBP to buy expensive London property.
I want to see how low GBP can fall i guess after GBP falled enough UK will re-open borders for foreign capital again
So brics Nations are out of GBP i want to see what the emirates and arabs will do will they exchange their currency into GBP ?
