From July 1, India’s proprietary trading firms and brokers face tighter funding rules. The Reserve Bank of India has ordered that all bank guarantees used in capital markets must be fully backed by collateral, with at least half of it in cash.
This step will sharply reduce leverage available to trading houses. Earlier, firms could stretch their capital with partial backing, but now they must commit more of their own funds. As a result, borrowing will become costlier and strategies that depend on cheap leverage, such as arbitrage and market making, will lose profitability.
Industry voices say the new framework will bring greater stability by curbing risky practices. However, it also squeezes margins and may lower liquidity in the markets. Proprietary firms will need to rethink their models, shifting towards more cautious and capital-heavy operations.
The immediate impact is clear. Funding costs are set to rise, leverage will shrink, and profitability will be under pressure. While the move strengthens the financial system, it challenges the flexibility of traders who thrive on speed and leverage.
The RBI’s stricter collateral norms mark a turning point for India’s prop trading industry, reshaping strategies and forcing firms to adapt to a costlier, more disciplined environment.
