(Reuters) -Intercontinental Exchange reported an increase in second-quarter profit on Thursday, as it benefited from strong trading volumes in its energy business.

The New York Stock Exchange parent reported adjusted earnings of $1 billion, or $1.81 per share, for the quarter ended June 30, compared with $876 million, or $1.52 per share, a year earlier.

Exchanges thrive during bouts of market volatility as investors frequently rebalance portfolios to seize opportunities and hedge against risks, driving up trading volumes.

U.S. President Donald Trump's sweeping tariffs triggered volatility in April, while tensions in the Middle East exacerbated in June.

The volatility index, a barometer for market uncertainty and Wall Street's most-watched gauge of investor anxiety, spiked to record levels in April before easing as optimism over potential trade deals calmed markets.

The company's revenue from trading in energy-related products jumped 27% to $595 million, while revenue from ICE's exchange business, the biggest driver of its revenue came at $1.42 billion in the quarter.

Shares of the NYSE parent were up 0.7% in premarket trading.
