Ken Griffin's Citadel's Indian operations reported impressive profit gains in the last financial year—a notable achievement given the regulatory headwinds in the region. India's market watchdog had tightened rules around derivatives trading, creating tighter compliance requirements for major players.

The move reflects how major financial institutions are adapting their strategies to navigate stricter regulatory frameworks across different markets. Whether this trend signals broader opportunities or just one firm's tactical advantage remains to be seen.
