Goldman Sachs is reportedly planning to lay off around 250 senior employees due to a slowdown in Wall Street's dealmaking and decrease in profits. This will be the third round of layoffs for the company in less than a year. Other Wall Street companies, including Morgan Stanley and JPMorgan Chase, are also planning to cut jobs in various divisions. The challenging financial conditions are affecting Wall Street's mergers and acquisitions dealmaking, leading to a sharp decline in Wall Street bonuses.
