It's hard to determine just where this logo comes from. Google Image Search turns up at least two different Credit Unions that seem to use it as a symbol for networking between unions, such as here. The exact same logo is also used by the Kuber Group, a conglomerate based in India, both on their website and their Facebook page.
The same Google Image Search turns up a good dozen variations, as well. <shrug>
