That is a great purchase, and a bargain, I think you could make a decent profit on that domain if you ever sell it.

You could develop a nice finance website on it, like tim said above a finance news aggregator to begin with would be a good idea until you have developed it.

Good luck with it

Then I would be tempted to turn the site into a what’s going on portal, find a couple of people who are economists but are also pretty adept at translating things into simple English, University under grads 3rd years would be the cheap option secondary school economics/business teachers another. Uni lecturer depending on budget. Get them writing what does this mean for us style posts. So an article on Interest Rates etc etc.

Also look at a couple of tools, mortgage calculator, currency conversion, stock tracker.

Then I would again noting the budget do a short couple of fun videos, to promote the articles make it wacky try and get people interested in visiting the articles and build up from there.

Not original I know but a sound strategy that can be repeated over and over again. By lowering the level even though its a high brow domain name your going to increase traffic. Such a site would be perfect for affiliate marketing.

You certainly seem to have a knack for digging out decent neglected domains.
