The impact of hard Brexit is key. The ‘experts’ don’t seem to know, so your opinion seems as good as any other.
I fear it will be quite harsh. The simplest explanation for the government’s dissembling to date is that all the smart people involved within government fear the worst.
There’s much talk of a soft Brexit being unacceptable because it is clearly worse than full membership of the EU. Less talk about how a hard Brexit will be better. Typically, vague words about freedom to trade.
For this free trade to be better than membership of the EU, Britain would have to get better than WTO terms with countries that the EU doesn’t have agreements with (mainly America and China?), and/or better than EU terms with countries like Canada and Japan, so much so that it offsets the worsening of terms with the EU, on the small proportion of the British economy devoted to tradable goods and produce. Not obvious how that will work.
The EU is happy to accept any sensible free trade deal on goods and produce. It has a large surplus after all. But it literally cannot be better than a free trade deal (and all the frictions these involve) without full compliance with the single market’s rules for trade in goods and produce, including consequential constraints on trade with third parties. This is a dilemma for Britain, not for the EU. Hence the white paper’s futile ambiguity on this.
EU companies do need sophisticated financial services. It is naive to think these can only be provided within a few hundred metres of Leadenhall market. The global financial services companies can and will be delighted to offer them wherever they are required, for the usual fee. It is naive to think that any sophisticated economy will agree to give up is rights to regulate its own financial services industry. Never going to happen. The business will move to the EU, and all of the customers, providers and regulators involved will cooperate to minimise the cost. If the City wants to sell financial services abroad to anyone, it cannot afford to play hardball with the Europeans as they ‘take back control’.
So far as I know, Brexit won’t really change UK-based financial services companies’ ability to trade internationally, so no gains there.
All in my humble opinion of course. I have been entirely unsurprised by developments to date, but from here on, I think there is lots of scope for unexpected and unpredictable developments. We, the British, unfortunately do live in the most interesting of times!
