FX rates in Nexus should keep broadly in line with rates in wider FX markets. This is because FX Providers in Nexus are likely to be active in other FX markets. If Nexus rates were significantly higher than other FX markets, FX Providers would reallocate funding towards the Nexus market, increasing supply and pushing down rates. Likewise, if Nexus rates were significantly lower than other FX markets, they would reallocate funding away from Nexus and towards other markets, reducing supply and pushing up rates.
