Ten years ago I gave a lecture on liquidity at Gresham College – “Liquidity: Finance In Motion Or Evaporation?”  – London, England (5 September 2007).  I recommend the transcript as easiest to read with the slides.  The lecture was actually scheduled back in February 2005 (yes) as I looked ahead ujneasily towards a liquidity crisis.  The timing turned out to be too good as I came back from summer break after BNP Paribas started the financial crises news and things lurched onwards to Bear Stearns, Lehman Brothers, RBS, etc.

In these days of Initial Coin Offerings (ICOs) this lecture seems to be coming back in popularity and I wonder about a reprise.  Meanwhile, I couldn’t resist ending the lecture with a little ditty of my own, based on Jonathan Swift’s construction around a flea, The Siphonaptera, that seems worth sharing again:

Big pools have little pools

which suck out their liquidity,

and little pools still lesser pools

and so on to aridity.

So, financiers observe, small pools

suck larger pools liquidity,

yet tinier pools drain other drops,

and so on to aridity.
