Economia and Peerindex have drawn up a list of those who have the most sway in the financial world, and are picked up and followed by key Twitter users.
Their online influence is measured with a score of between 0 and 100 to gauge their authority across social media.
Headed by Nouriel Roubini, the respected American economist, the top accounts are those whose messages are retweeted, shared, responded to or argued with the most.
These tweeps will keep changing in the listing as they gain or fall in significance. Follow using the hashtag #Finance100.
