Libor - or the London interbank offered rate - is set every morning and is a key part of the relationship between borrowers and lenders around the world.
The alleged offending by Read and his co-accused is said to have taken place between August 2006 and September 2010 while one of their clients, Tom Hayes, worked at both UBS in Japan and then at Citigroup.
"Knowing or believing that UBS, through the trading activity of Tom Hayes and others, was a party to trading referenced to London Interbank Offered Rates for Japanese Yen [Yen Libor], they dishonestly agreed to procure or make submissions or rates by panel banks into the Yen Libor setting process which were false and misleading," according to documents detailing the charges in the case.
It is further alleged the defendants deliberately disregarded the proper basis for making Libor submissions and hoped to create an advantage for Hayes' trading, "thereby intending to prejudice the economic interests of others".
Although Read moved to New Zealand in 2007, he continued working for ICAP - which in 2013 was fined US$87 million by regulators on both sides of the Atlantic for its role in the Libor scandal, which has seen numerous financial institutions penalised.
Neither Read nor his co-accused in his trial, Colin Goodman and Danny Wilkinson, are still employed by the London-based firm, which called the trio and others former workers "rotten apples" when the rates-rigging allegations emerged 15 months ago.
Read did not want to discuss the case when contacted last month.
He and his co-accused are also facing wire fraud charges in the United States over their alleged attempts to manipulate the rates.
Those charges come with a maximum penalty of 30 years' jail and it is understood Read has not entered a plea to them.
The Department of Justice did not respond to Herald inquiries about the prosecution.
Hayes is also facing charges in both the US and UK.
His trial in Britain is expected to begin this May.
