Verdict

Interactive Brokers has the best FX pricing of any mainstream broker by a wide margin. Their FX spread is 0.08% mid-market (or ~$2 fixed minimum per conversion), which means a $10,000 INR→USD conversion costs ~$10 — vs $50-150 at Indian domestic brokers. If you're serious about investing globally and want to minimise the FX drag, IBKR is the answer. The interface is complex, but worth learning.

Frequently asked questions

Can Indian investors use Interactive Brokers?

Yes. Indian residents can open an IBKR account and invest in US stocks under the RBI's Liberalised Remittance Scheme (LRS), which allows up to $250,000/year in foreign investments. You'll need PAN card, Aadhaar, and a bank account for the LRS remittance.

What FX rate does IBKR use for INR to USD conversion?

IBKR charges approximately 0.08% above the interbank mid-market rate (minimum $2 per conversion). On $10,000 INR→USD, that's a ~$10 FX cost. Compare: Zerodha and most Indian brokers charge 0.5-1.5% for the same conversion ($50-150).

How does IBKR compare to Zerodha for US stocks?

IBKR is far cheaper on FX. Zerodha uses a bank partner for the LRS transfer which typically charges 0.5-1% FX margin. IBKR handles the FX conversion internally at 0.08%, saving $40-90 per $10,000 invested. IBKR also has direct access to US markets; Zerodha uses Vested as an intermediary.

Is there a minimum investment for IBKR?

No. IBKR removed its minimum account balance requirement. You can start with any amount. However, the $2 minimum FX conversion fee means very small conversions (under $1,000) have disproportionately high FX costs — at that scale, a fractional share platform may be more cost-effective.
