Until we have independent evidence of what is really going on with Farage’s accounts, we cannot definitively rule out the possibility that the bank has closed his accounts for legitimate commercial reasons. But even if this particular account closure had nothing to do with political prejudice, there is no denying that the past couple of years have produced more than one isolated incident of banking services penalising customers for political or ideological reasons.
Of course, you might say, “If you don’t like your bank, go find another one.” And if it were just one idiosyncratic bank that decided to target customers on political or ideological grounds, you would be right: in that case, it might not be such a big deal, because you could just go to another bank, and put the whole sorry episode behind you.
Imagine a society in which outspoken conservatives, or Brexiteers, or libertarians, or socialists, were systematically locked out of banking services: those dissenting openly from the political views of the banking establishment would be condemned to live as economic pariahs: no mortgage, no credit cards, and no way to conduct a normal business. Citizens would effectively forfeit their right to buy and sell, or participate in a market economy in a normal way, just because they expressed opinions disapproved of by the banking establishment.
Banks would then become instruments of political persecution and totalitarian groupthink instead of institutions devoted to the provision of banking services to the citizenry at large. The price of political dissent would become far too high for many citizens. The public square would quickly degenerate into an echo chamber of opinions approved by the banking establishment.
Since bankers are not infallible gods, the opinions they approve may be right, wrong, or plain crazy. Either way, under a talibanised banking system, such opinions would face little opposition. After all, most citizens, if forced to choose between expressing dissenting opinions, and surviving economically, would choose economic survival. And many who cannot bear losing their political voice would probably emigrate to a country where banks still provide their services to citizens without regard to their political opinions, leaving behind them a citizenry that is like putty in the hands of its banking masters.
