Current and savings accounts run by banks and building societies are to be regulated by the City watchdog, it has been announced.
At the moment they operate under voluntary rules known as the Banking Code.
But from 1 November the FSA will take over with a new set of rules and the ability to fine banks that do not comply.
We ask FSA retail managing director Jon Pain why he has decided to impose FSA rules on the banks.
Plus we speak to Eric Leenders, director of retail services at the British Bankers' Association and Adam Philips, acting chairman of the Financial Services Consumer Panel.
The Budget in detail
The government wants people to scrap their old cars and buy new ones.
Chancellor Alastair Darling has delivered his second Budget to Parliament against the backdrop of a deepening recession.
High earners will be hard hit with a new 50p tax rate for earnings over £150,000 and a restriction on the tax relief for pension contributions.
There was a boost for savers with an ISA limit rise and the amount older people can have in savings before Pension Credit is affected will also go up.
He also announced a car scrappage incentive and the withdrawing of tax relief on second homes.
Money Box examines the detail in these and other changes to find out how you will be affected.
We are joined by:
- John Whiting of tax advisers PricewaterhouseCoopers
- Adrian Lowcock, senior investment adviser at Bestinvest
- Anna Pearson, policy manager for Age Concern & Help the Aged
Lending to vulnerable customers
Bob Howard asks if more could be done to help vulnerable people
Should financial institutions dealing with vulnerable customers be doing more to encourage them to seek advice from their friends, family or advice charities?
Mental health campaigners say some people who do not seek advice are being mis-sold products.
But firms are also under a legal duty not to discriminate against customers who have a mental health problem.
Bob Howard has been investigating.
Other news: Financial compensation
The compensation limits for investments, home finance advice and deposits will be the same at £50,000 from January 2010, the FSA has said.
The Financial Services Authority hopes this will simplify the system.
Under the present system some parts of these claims are paid out at 100% and others at 90%.
