Why Compare OKX and Interactive Brokers?
If you're a non-US resident wanting to buy US stocks, these two platforms represent the two main approaches:
- OKX: Crypto exchange with stock tokens (derivatives) — the new way
- Interactive Brokers (IBKR): Traditional international broker — the established way
Both serve international investors. Both let you buy US stocks without an SSN. But the costs, features, and experience are very different.
How Do OKX and Interactive Brokers Fees Compare?
Trading Fees
| Fee Type | OKX Stock Tokens | Interactive Brokers |

| Buy $10,000 of Tesla | $5.00 | $1.00-5.00 |

| Crypto transfer | $0.50-2 network fee | Not available |
| Typical cost for $1,000 | $10-20 | $15-50 |
Winner: OKX — far more deposit options and usually cheaper, especially in developing countries where wire transfer fees are high.
Withdrawal Fees
| Method | OKX | Interactive Brokers |
|---|---|---|
| Local bank (P2P) | 0-2% | N/A |
| Wire transfer | N/A | $10 fee + bank charges |
| Crypto | $0.50-2 | N/A |
| Typical cost for $1,000 | $10-20 | $10-35 |

Other Fees
| Fee | OKX | Interactive Brokers |
|---|---|---|
| Account maintenance | $0 | $0 (removed in 2024) |
| Inactivity fee | $0 | $0 (removed) |
| Funding rate | ~0.01%/8hrs (~0.03%/day) | N/A |
| Currency conversion | Included in P2P rate | 0.002% (very cheap) |
| Dividend | N/A (no dividends) | Received (minus 20% withholding tax) |
Note: OKX's funding rate is a significant ongoing cost for long-term holders. If you hold a position for 1 year, the funding rate alone could cost 10%+. This makes OKX better for short to medium-term trades.
