The Bank of England is pledging to use its post-Brexit freedoms to introduce a "more British style of rule-making".
It is seeking to axe overly-expensive and onerous rules that make it hard for small banks to offer cheap home loans, following a legal overhaul that gives the institution more power to set its own agenda.
The Telegraph reports that the Government is abandoning the top-down approach to regulation that was beloved of Brussels where watchdogs were given a strict set of rules and ordered to follow them closely with no room for interpretation.
A law currently going through Parliament will give the Bank far more power to make changes to the rules without new legislation for every detail.
The aim is to produce regulations designed by experts who are focused on making the markets work properly rather than following a political agenda.
Sam Woods, head of the Prudential Regulation Authority - a part of the Bank which sets rules for the City - said in its annual business plans that the proposals "will enable us to adopt a more British style of rule-making, with less fine detail in legislation and more ability for us to maintain and develop a coherent and dynamic rulebook".
Mr Woods is expected to use these powers to reduce the amount of capital that small banks have to hold onto if they want to offer products such as mortgages.
He said:
"We are already developing a simpler regime for smaller banks, which will be good both for safety and soundness and for competition - we call this 'strong and simple' because we have no interest in a weak regime."
If the planned reforms work, they could lead to a fall in the costs that challenger banks face when issuing mortgages, cutting prices and boosting competition to the benefit of house buyers.
Ian Gordon, an analyst at Investec, told the Telegraph:
"Put simply, it is uneconomic for a challenger bank to operate in the standard 'vanilla' mortgage market.
"The only markets where challenger banks or specialist banks can potentially make a sensible living is in higher-margin products - whether that be professional buy-to-let, or high loan to value, or lending to non-standard or self-employed (customers).
The current regime forces banks into niche or higher-risk (products)."
