Total return swap

I listened to this WSJ podcast about recent block selling from some banks caused by a total return swap.

Apparently, it is possible to structure financial instruments into various forms as long as there are counter parities on each side.
In that particular case, a bank purchased a set of stocks and swapped the variable return (dividends and capital gains/losses) with a fixed return, and had to sell the assets when the counter party failed to pay for capital losses, causing further downward spiral.

I guess it is a sign of lockdown that I would sit in front of a refrigerator and draw this.

This is an experiment with Spark logo-maker and Fresco motion.

NFT art

Some information that I have found helpful in understanding the recent NFT art phenomena.

A good NPR podcast introducing NFT.

CNN on NFT art boom.

NFT is obviously not the first asset bubble.

Beeple’s 69-million NFT, and why the buyer thought it is worth the price.

Aaron Hertzmann’s article about the similarities and differences between traditional and NFT arts.

An NFT is essentially a URL and the block-chain does not store the artwork itself.

As expected, one of the major NFT art exchanges may have security issues, even though their system does not seem to be compromised.

The auction process may be off the blockchain but with reduced computation and energy consumption.
