2016 crash

There is bank run risk. Its first symptom would be lots of loan availability on secondary markets, followed by loss of liquidity on secondary markets as investors try to sell out of loans that they think are risky. Mitigation for this would be offering to sell at a lower price to encourage buyers, something that a lender might try to do if selling some of their P2P was a better plan than selling other investments that may have fallen a lot in value, like shares.

Reduced willingness to invest might be a nasty shock to any platforms that rely on initial charges to borrowers for most of their income. No defaults required, investor risk reducing will do the job.

Laws have been changed to expand the toolboxes. The current resolution process for globally important banks is a holding company that owns the debt and an operating company that owns the customer accounts. Resolution splits off the operating company to a new parent while shareholders and potentially bond holders get to bear the losses. For smaller banks there are requirements to have readily available identification of all balances so that within a few days the FSCS can pay out using this data. This may avoid the massive bailout situation, though the massive bailouts worked quite well and quite profitably overall for governments.

A revenue model that doesn't rely on ongoing new loan sales, ample operating reserves and a secondary market with pricing flexibility to reduce liquidity loss for investors, though the RateSetter and Zopa approaches might also work for this, at a potentially more considerable potential haircut due to their sale charging models.

Back in 2008 the first big symptom was evaporating liquidity in bond markets.

100% agree regarding property. I just discovered one of the new offerings on a property equity site was 20% overvalued. Please don't trust the supplied valuations and do your DD.

I'm of the belief that a large correction is coming (of course no one knows when but all the red warning flags are staring us in the face). I'm sitting about 75% cash.

I wouldn't touch the FTSE100 at all at the moment. Much safer in the US Indexes now IMO.

None that I can think of.  It may be more pertinent to ask how far away any particular platform is from being profitable and what level of loan volume / value growth that requires.

Maybe you could use it to try some of this peer to peer lending I heard about.

Quite right. Put it in Ablrate and all your eggs are in one basket with the un-lent complaining also that you have bagged the best loans. Put it in another p2p operator and you are disloyal to Ablrate and not prepared to lead by example and put your money in. The mattress should safest - but not the one in the office.

Nothing that makes it worthwhile. They have a good mix of investments though so there is probably a cash equivalent that makes sense.
