Market turmoil brings a bountiful harvest season, Wall Street big banks' performance exceeds expectations.

President Donald Trump's tariff policy has stirred global markets and also helped Wall Street's major banks set new historical records. JPMorgan Chase's stock trading department achieved its strongest second quarter performance ever, while Citigroup's trading department also achieved its best performance in five years. The performance of these two banks' trading departments easily surpassed analyst expectations, and even their investment banking businesses performed better than expected, despite concerns that volatility could hinder trading. Citigroup CEO Jane Fraser told analysts on the earnings call, "In the new world order, volatility will be the norm, not the exception. We will benefit from it." Since Trump announced tariffs on many trading partners in early April, the market has experienced intense volatility. This volatility has been a catalyst for JPMorgan Chase's fixed income trading department, which generated $5.69 billion in revenue during the three months, while the stock trading department set a new historical record of $3.25 billion in the second quarter, second only to the historical record set in the first quarter of this year. As for Citigroup, its stock trading department recorded $1.61 billion in revenue, and its fixed income trading business increased by 20% year-on-year, reaching $4.27 billion, exceeding market expectations.
