Fascinating stuff.
"In 2012, revelations emerged about the manipulation of the London Interbank Offered Rate (LIBOR) by various global banks. This scandal led to a significant shift in regulatory attitudes towards LIBOR, which was deeply embedded in the financial system due to its connection with approximately $300 trillion worth of loans, derivatives, and other financial instruments across multiple currencies.[3] Contributing to the concerns was the noticeable decrease in the volume of transactions underpinning the benchmark. Consequently, UK financial regulators established a deadline of 2021 for financial firms and investors to complete their transition away from the LIBOR.[3]"
The Fiat system never ceases to surprise in the many ways it fails :D
