Over half of consumers think that the government's handling of the banking industry has got worse over the last five years, when the financial crisis officially started.
A survey compiled by consumer group Which? also showed that 71% of people don't think UK banks have learnt their lesson from the financial crisis, up from 61% in September 2011.
Almost half of consumers said they were worried about mortgage rates and the level of household debt.
As the parliamentary inquiry on banking standards prepares to get underway, consumers said they have low expectations that the inquiry will lead to change, with only a quarter of people confident that it will lead to positive improvements in UK banks.
Which? chief executive Peter Vicary-Smith said that scandals exposing mis-managemnet and corruption in the banking system has damaged public confidence in the banking industry.
"The parliamentary banking inquiry must produce proposals for fundamental change to the culture and practices of the banks and put the best interests of consumers back at the centre of reforms. Nothing should be off the table if the government is to rebuild consumer confidence in this essential service."
The survey also showed that 84% of people think that the banks have not done enough to change the banking industry to ensure another credit crunch does not happen again, while 80% think there is a deeper problem with the culture in banks than just a few individuals making bad decisions.
