The Financial Conduct Authority has snapped up the former chief executive at Depfa ACS Bank Ireland to become head of investment banking in its supervision division.
The FCA said in a statement that she will start in early May this year and will report into Will Amos, the regulator's director of wholesale banking and investment management.
"I am delighted that Julia [Hoggett] is joining us - she has a huge amount of industry experience, with an excellent understanding of financial institutions and specific investment banking experience," said Clive Adamson, director of supervision at the FCA.
Hoggett moves immediately from Bank of America Merrill Lynch, where she worked as a managing director on the debt capital markets desk.
She also worked at JPMorgan in debt capital markets roles covering sovereign, supranational and agency and emerging markets clients.
"I am honoured to be joining the FCA and to be part of the further development of financial market supervision in the UK," said Hoggett.
"I am looking forward to working closely with colleagues and the wider market to ensure that the United Kingdom remains at the forefront of the investment banking industry and does so in a manner which places the protection of consumers, of all forms, front and centre."
Her appointment follows a number of other high profile hires for Adamson's supervision division, including Robert Taylor as the FCA's head of wealth management and private banking in January 2014 and James Kelly as an adviser in the wholesale banking and investment management division in February.
Karina McTeague was recruited from Lloyds Banking Group last year as director of retail banking.
In the policy division, Mary Starks and Deborah Jones were appointed to share the post of director of competition in September.
