How to change the base currency on OKX? (Display settings)

Accessing Display Settings on OKX

1. Log in to your OKX account using a verified device and active session.

2. Locate the user profile icon in the top-right corner of the trading interface.
3. Click the icon to open the dropdown menu and select “Settings”.
4. Navigate to the “Display” tab within the Settings panel.
5. Scroll down until you see the “Base Currency” section, which controls how asset values are shown across dashboards and order books.

Changing Base Currency for Portfolio View

1. In the “Base Currency” dropdown under Display settings, click the current selection (e.g., USD).

2. A list of supported fiat and stablecoin options appears — including BTC, ETH, USDT, EUR, JPY, KRW, and GBP.
3. Select your preferred base currency — the change applies instantly to portfolio valuation, profit/loss calculations, and balance summaries.
4. The total portfolio value recalculates using real-time exchange rates sourced from OKX’s internal price oracles.
5. Historical PnL charts and position valuations reflect the newly selected base without requiring page refresh.

Impact on Trading Interface Elements

1. Order book depth columns update to show bid/ask sizes and cumulative volumes denominated in the new base currency.

2. Market price tickers above each trading pair adjust to display relative value changes against the chosen base.
3. Margin and futures positions show liquidation prices and margin ratios recalculated using the updated base conversion logic.
4. Trade history entries retain original execution denominations but add a secondary column showing equivalent value in the selected base.
5. Deposit and withdrawal confirmation modals continue to display native asset amounts but append estimated base currency equivalents based on current mid-market rates.

Limitations and Constraints

1. Base currency selection does not affect settlement logic — all contracts and spot trades settle in their native quote assets.

2. Certain institutional accounts may have restricted access to non-USD bases due to regional compliance policies enforced by OKX’s KYC engine.
3. Cryptocurrency-based bases like BTC or ETH do not support fractional display below 0.00000001 units, potentially truncating precision for low-value tokens.
4. Multi-currency wallets created via OKX Wallet integration maintain independent balances and are unaffected by display-level base currency changes.
5. API users must manually configure base currency in client-side formatting layers — the REST or WebSocket endpoints return raw asset-native values only.

Frequently Asked Questions

Q: Does changing the base currency affect my actual holdings or trigger any on-chain transaction?A: No. This is purely a frontend display preference. No blockchain interaction occurs. Holdings remain unchanged in their native denominations.

Q: Why is CNY not listed as an available base currency option?A: OKX complies with regulatory restrictions in certain jurisdictions. CNY availability depends on account verification level and regional licensing status.

Q: Can I set different base currencies for spot and derivatives interfaces separately?A: Not currently. The base currency setting applies globally across all OKX product modules — spot, margin, futures, options, and earn.

Q: What happens if the selected base currency experiences extreme volatility during market gaps?A: Portfolio valuation updates in real time using OKX’s aggregated price feeds. Temporary discrepancies may appear during flash crashes or illiquid conditions, but no manual correction is required.
