Hot money.

I'd favour the spending it option rather than trying to launder it. I'm confident I could spend through quite a lot of it on various things, assuming the notes don't go out of circulation for the duration.

This is one of those things think about when I can't sleep. It's an interesting problem, I think the big issue is to turn notes into some other form of value.

I think you need to buy assets which can be purchased for cash, don't depreciate, and are easy to store. Personally I'd go to 2nd hand jewellers, watch shops, antique dealers & fairs, pawnshops, and spend £200 - £500 in each, no more. Visiting ten shops a week, it'd take a few years to build up a physically small stash of value. No internet transactions, no eBay.

Cash them in as and when you need them, the same way you bought them. Maybe in other countires, to make it harder to trace. You'll lose maybe 1/3rd of the money, but who cares?

A nice problem to have

Yup, that's exactly how I'd do it.

I'd go rallying. That would make short work of it all.

Or touring car racing. After all, it worked for Vic Lee.....

Trillions of dollars of dirty money has been cleansed worldwide this century by the Chinese, Africans and other emerging rich. They have taken over from the Europeans and Americans who ruled last century. It is surprisingly common and still fairly easy, and there are hundreds of ways to do it. £750k is pin money.

Diamonds are popular. Very easy to buy and sell and transport across borders in small packages like pill bottles.

Private yachts are popular. Sail to the Caribbean or South America or Hong Kong / Macau and deposit with a friendly bank, who will run it around the world and hide your trail.

Car washes are popular. High-cash, low-receipt business. More suited to continuous flows than one-offs, because of the logistics involved, hire staff, pay overheads, etc.
