LONDON, United Kingdom (CMC) — The London-based Commonwealth Secretariat has warned that key industries in some Commonwealth countries, including the Caribbean, could take “massive hits” if appropriate steps are not taken following the United Kingdom’s decision to leave the European Union after 43 years.

It said the forecast over so-called Brexit comes from policy experts’ analysis in two new research papers that have now been published by the Secretariat.

 “Brexit is a journey into unknown trading arrangements, both for the UK dealing with the EU, and the UK’s trading relationship with a large number of developing countries. Many have benefited from EU trade preferences,” said Dr Mohammad Razzaque, head of the Secretariat’s international trade policy section.

The analysis is part of the Secretariat’s peer reviewed ‘Trade Hot Topics’ series.

The latest studies suggest that the uncertainties caused by Brexit may weaken the chances of world economic recovery. This in turn will have severe implications for many developing and so called least developed countries (LDCs).

The EU provides special trade deals to support these vulnerable countries, using often complex mechanisms and Razzaque warns that if equivalent provisions are not provided while the UK leaves the EU, it could mean additional annual export duties of more than £600 million for these countries.

“For 36 Commonwealth developing countries, this potential tax hike could be as high as one per cent of their total exports to the UK,” he said, adding “for the likes of Bangladesh, Mauritius, Seychelles and Swaziland this could be more than 10 per cent”.

He warned that unless similar EU trade preferences are maintained by the UK, Bangladesh for example will have to pay £220 million in tariffs to UK customs.

“That would put even more pressure on the four million, mainly women, workers facing already appalling conditions.”

The Commonwealth Secretariat noted that strong historical ties mean at least 20 Commonwealth developing countries rely on the UK for 10 per cent or more in trade. The UK is often a niche market in certain sectors.

“More than 80 per cent of St Lucia’s exports, mainly bananas, to the EU is bound for the UK. Remember that the country’s banana industry has witnessed tremendous competitive pressure,” Razzaque warned.

“Unless it secures the same level of market access provision as in the EU, post-Brexit trading could deal a further blow to the sector. Similarly, Fiji, a Pacific Island state, sources almost two-thirds of its European export from the UK alone. In 2014, 95 per cent of Fiji’s exports to the UK was raw sugar.”

The Commonwealth’s developing countries export a total of about £25 billion to the UK. A weak pound, following the Brexit referendum, will have resulted in a significant loss in export value for these countries.

“It’s not just trade Brexit will affect. The impact of a weaker pound will affect overseas aid from the UK. So imagine a 10 percent depreciation of sterling. $20 billion UK aid is only worth $18 billion.

“Think about how that extra $2 billion could have been spent. We’re talking about here, among other things, the UK’s helping 13.4 million people with emergency food assistance and supporting 11 million children with their education in the past five years,” Razzaque said.

But the organisation grouping former British colonies said however, all is not lost.

The Secretariat’s policy papers have used scenario analysis to produce four options which could help avoid the most vulnerable countries being put at risk.

According to one of the papers, the UK’s commitment to promoting trade-led development has been globally influential. It has always recognised and championed the special needs and challenges facing such vulnerable country groups as the LDCs, sub-Saharan Africa and small states.

“The UK is one of the few high-income countries which fulfils the UN target of providing 0.7% of gross national income as overseas development assistance.

“It’s in this spirit that the UK’s newfound trade policy sovereignty should result in continuity and improvements over the currently existing trade preferences for vulnerable countries,” Razzaque added.
