Private equity and venture capital deal value worldwide sank 56.1% in June to $62.63 billion from $142.73 billion in the same month a year ago, according to S&P Global Market Intelligence data.

There were 1,813 deals announced during the month, a 32.6% decline from 2,691 transactions year over year.

The U.S. and Canada accounted for most of the deals in June with 590 transactions at an aggregate valuation of $29.92 billion, Market Intelligence data showed. Asia-Pacific came in next with 567 deals totaling $10.51 billion, followed by Europe, which saw 525 transactions worth $20.26 billion.

For the second quarter, total transaction value slipped 29.4% to $220.92 billion from the same quarter the previous year, while the number of announced deals fell about 20.5% to 5,393.

The surge in volatility and slowdown in private equity transactions were driven by the onset of new risks such as inflation, increasing interest rates, geopolitical turmoil and heightened government scrutiny, professional services giant PwC said in its Deals 2022 Midyear Outlook report.

"While deal volume was still strong during the first quarter, most of the decline in the first half of the year was due to the second quarter, when volume fell precipitously," the report said.
