Barclays was the first to settle with US and UK regulators over evidence that traders had been fixing the bank’s LIBOR and EURIBOR rate submissions to the Bank of England.
Agius’ memo is the first official suggestion that the Financial Services Authority may hit up to 15 other banks being investigated harder than Barclays.
The memo said: “As other banks settle with authorities and various government's inquiries shed more light our own situation will eventually be put in perspective.”
It comes after the New York Fed published emails sent by Barclays to the US regulator accusing Lloyds Banking Group of rigging LIBOR rates in 2007.
The latest twist in the LIBOR scandal may come later today when Financial Services Authority Lord Adair Turner and acting enforcement director Tracey McDermott face the Treasury Select Committee to give evidence.
Barclays’ former chief operating officer Jerry Del Missier is also due to give evidence to MPs today.
