Jane Street, which has been accused of market manipulation by Indian authorities, has deposited $567 million in escrow accounts which will allow the U.S. firm to resume trading, two sources with direct knowledge of the matter said on Monday.

Whether arbitrage or manipulation, the Jane Street episode highlights a critical truth: markets need more transparency, more accountability, and more human judgment.

SEBI has banned the firm from India’s securities markets. The drama has thrown a bright light on Jane Street, a company of legendary opacity even in an industry that prioritises secrecy. And it could carry political and regulatory consequences, not just for Jane Street, but for an entire, ascendant industry of marketmakers.
