Gain Capital institutional volumes now rival those of smaller Forex ECNs.

Similar to what we’ve already seen at leading global FX brokers FXCM, Alpari, and GMO Click, Gain Capital (which as we reported earlier is now beginning to report its Forex.com monthly volumes) also registered solid numbers in May 2013. Retail volume came in at $161.5 billion, up 11% from April. Institutional volumes came in at an all-time record for Gain at $382.7 billion, up 21% increase from March.

Overall, FX volumes totaled $544 billion at Gain Capital across all its brands in May (mainly Forex.com and Gain GTX), up 18% from April and an all-time best for the company. Note that these figures do not yet reflect Gain’s acquisition of GFT, which is still pending. Adding in GFT should give a further $50-75 billion per month boost to Gain’s retail numbers.

We’ll see how the stock market reacts to the announcement (it should be positive!), given that Gain Capital shares rose to a 52 week high last week. At $5.81 (Firday’s close), Gain Capital (NYSE: GCAP) shares are still significantly below their December 2010 IPO price of $9 a share.
