Lloyds Banking Group's outgoing chief executive, Eric Daniels, is to launch a major drive to improve the transparency of the lender's financial products in his last three months in charge.
Speaking to the Sunday Telegraph, Daniels argued a lot of the poor perceptions of banks were the result of excessively negative attacks on the sector.
"One of the things that we can't really prevent, which shapes customer perception, is all the negative articles about what is happening with banks and banking," he said.
"I think banker-bashing has to be about the most popular indoor sport in the UK."
Daniels said Lloyds was happy to go it alone and provide more details to customers on how much they are earning in interest on their savings.
"We are going to act unilaterally whether the rest of the sector follows or not and make changes to our transparency starting early next year, so we will have real clarity around rates and average balances so that customers can really see exactly what their current account is doing and what interest they may be forgoing by not moving money into a savings account," Mr Daniels told The Sunday Telegraph.
"We hope the rest of the industry comes along with us as we think that would be a good thing."
As part of the new Money Manager service, Lloyds customers will be provided with statements that tell them the rate of interest they are earning on their money for the first time.
The move by Lloyds comes at a time when the bank is under pressure to convince politicians its market share is not anti-competitive.
About a third of UK current accounts are held with Lloyds, giving it the largest market share of any bank in the country. It is also the biggest mortgage lender in Britain.
Daniels also said he wanted to make switching bank accounts easier for customers.
However, he said moving to a system in which people could take their account number with them to another bank would be unnecessarily expensive.
"Having a universal number is a very costly solution," he said. "There may be ways with fairly simple technology to ensure that when your BT bill comes to your old bank it gets transported across to your new bank.
"We don't think the best consumer outcomes have been achieved yet. We can offer better value and we think that [moves on] switching and transparency can be very helpful. If it is easier to switch and we can remove uncertainty then we are happy to do it. It will mean a more competitive market."
