While normally "volatility is a tailwind for us," the looming chaos from Brexit kept the small and midmarket corporate customers of foreign exchange trading firm OFX out of the market, Skander Malcolm, the firm's CEO told his company's AGM yesterday. Consequently, the ASX listed company saw a 16 per cent decline in its market size in the quarter to June 2019. This ranks Brexit as a bigger near term threat to OFX profitability than blockchain systems, cryptocurrencies characterised by Malcolm as "highly volatile, highly risky and almost entirely unregulated ... [and] not for the preferred method of exchange for the types of clients that we target."
