* CEO says spoke to regulators in Frankfurt, Paris and Amsterdam
* CEO says company does not plan to move many jobs from London
* Increase in equity volatility at the start of the year (Adds media call comments, share movement, details on quarter)
Aug 7 (Reuters) - TP ICAP has chosen Paris as its European Union hub once Britain leaves the bloc, attracted by the city's focus on banking and asset management, its new CEO said on Tuesday, as the world's largest interdealer broker posted lower first-half profit.
Nicolas Breteau, who took over as CEO last month after his predecessor was fired, told reporters on a call that TP ICAP had spoken to regulators in Frankfurt, Amsterdam and Paris before picking the French capital as its EU headquarters post-Brexit.
Paris is competing with Frankfurt, Dublin and Luxembourg to win finance jobs in the wake of Britain's departure from the EU next March.
London will remain the company's headquarters, said Breteau, a Frenchman who also holds a British passport. The company did not plan to "move many jobs out of London," he said.
Lower volatility in financial markets has hurt the company as investors reined in risk-taking and stock markets racked up a decade of gains. TP ICAP said pre-tax profit fell 52 percent to 34 million pounds ($44.03 million) in the six months ended June.
TP ICAP, however, said conditions in financial markets had been "supportive" in the first half, with an increase in equity volatility at the start of the year, helped by rises in the U.S. federal fund rate.
The company's shares were down 1.8 percent at 287.2 pence at 0828 GMT.
The company fired its previous chief executive, John Phizackerley, last month and warned rising costs related to Britain's EU exit and the EU's new rules on market transparency, MiFID II, would see profit fall short of expectations this year.
TP ICAP said on Tuesday it expects 2018 results to be in line with current market expectations.
"Today's interim results were broadly as expected and is the first stage in rebuilding confidence after the shock warning in July," Peel Hunt analyst Stuart Duncan said.
France has decided to pare back financial regulations to EU minimums and introduce new tax incentives to make Paris a more attractive finance hub.
Most of these changes are planned for the end 2018, as countries across the EU battle to attract bankers from London amid uncertainty over the impact of Brexit on the region's biggest financial center.
TP ICAP operates in Frankfurt, Paris, Amsterdam, Madrid and other locations in Europe. The company has been in Paris for over 20 years.
The company also said iSwap, a London-based electronic trading platform for over-the-counter interest rate derivatives, was expected to choose Amsterdam as its EU hub. TP ICAP is a major shareholder in iSwap.
TP ICAP was formed by Tullett Prebon's buyout of its main rival ICAP's voice broking business, and the deal reflected the growing strains on one of the City of London's trademark industries - the phone-toting brokers who acted as go-betweens for major banks and financial firms in currency, energy and interest rate markets.
