(Reuters) -Goldman Sachs is set to see its busiest week for initial public offerings since July 2021, its CEO David Solomon said in a CNBC interview on Wednesday.

His comments come after the Swedish buy-now, pay-later lender Klarna made its long-awaited New York debut earlier in the day, setting the stage for more IPOs from fintech hopefuls.

"This week, we will do more IPOs and have more IPO activity at Goldman Sachs than we've had since July 2021," he said.

Rallying equity markets and bumper first-day performances from high growth tech-focused stocks have revived investor confidence in new issues, which had plummeted in April after sweeping U.S. tariffs roiled global markets.

Design software firm Figma and crypto exchange Bullish's shares more than doubled on their first trades, while space tech firm Firefly Aerospace surged nearly 56%.

In anticipation of the long-awaited recovery in dealmaking, Wall Street banks have hired dozens of senior executives in recent months.

"M&A activity is up about 32% year over year but bigger than $10 billion (deals) activity is up 100%," said Solomon.

Despite a jam packed fall IPO window, some risks linger.

Inflation remains above the Federal Reserve's 2% target, while the U.S. labor market has begun to show cracks, sparking concerns over the perceived strength of the U.S. workforce.

"We've seen some job data that indicates that there has been some softening," Solomon said.

The impact of tariff policy remains an overhang on the markets, as companies and investors aim to gauge the hit to consumers pockets from the on-again, off-again duties.

"There's no question in my mind that it's having an impact on growth," Solomon said on the uncertainty around trade policy, while adding that its impact is hard to quantify.
