What Is OKX Shark Fin?
OKX Shark Fin is a structured savings product that combines principal protection with performance-based rewards. When you subscribe, your capital is safe, and you're guaranteed a minimum return—even if market conditions don’t align with your expectations.
The product rewards users when the price of the underlying asset (such as BTC or ETH) settles within a specified range at the end of the term. This makes Shark Fin ideal for traders who anticipate moderate price stability or controlled volatility.
Key Features of Shark Fin
- Principal protected: Your initial investment is fully secured.
- Guaranteed minimum APR: Earn a base return regardless of market direction.
- High potential APR: Achieve significantly higher yields when price conditions are met.
- Flexible subscription terms: Choose from 1-day, 3-day, or 7-day durations.
- Multiple asset options: Subscribe using USDT, BETH, or OKSOL—earnings are paid in the same currency.
- No hidden fees: Zero trading or processing fees on subscriptions.
- Dual market outlooks: Take bullish or bearish positions on major cryptocurrencies.
This flexibility empowers users to align their strategy with market sentiment without risking their capital.
How Does Bullish Shark Fin Work?
A bullish Shark Fin is ideal when you expect the price of an asset like BTC or ETH to rise moderately but remain within a specific upper and lower bound.
At settlement, if the asset’s price closes within the predefined range, you earn a variable APR—higher as the price approaches the top of the range. If it settles outside the range (either too low or too high), you still receive a fixed basic APR.
Earnings Formula
Your total return is calculated using this formula:
Subscribed Amount × (1 + APR × Term in Days / 365)
Let’s explore three real-world scenarios.
Bullish Shark Fin: Example Breakdown
- Subscription amount: 1,000 USDT
- APR range: 1% (basic) to 18% (maximum)
- Term: 7 days
- BTC price range: $18,000 – $21,000
Scenario 1: Price Below Range
- Expiration price: $17,000
- Since $17,000 < $18,000, the price is below the range.
- You receive the basic APR of 1%.
Earnings:
1,000 × 1% × (7 / 365) = 0.192 USDT
Scenario 2: Price Within Range
- Expiration price: $19,500
- Falls within $18,000–$21,000 → eligible for performance-based APR.
- Let’s assume the payout APR is 11% based on proximity to the upper limit.
Earnings:
1,000 × 11% × (7 / 365) = 2.110 USDT
Scenario 3: Price Above Range
- Expiration price: $24,000
- Exceeds $21,000 → outside the range.
- You receive the basic APR of 1%.
Earnings:
1,000 × 1% × (7 / 365) = 0.192 USDT
👉 Start earning with bullish Shark Fin and capitalize on upward market momentum safely.
How Does Bearish Shark Fin Work?
The bearish Shark Fin caters to users who believe the market will decline or remain stable within a downward-trending band. It functions similarly to the bullish version but rewards outcomes where prices stay within a range that reflects a bearish outlook.
If the settlement price lands within the range, your APR increases as the price moves closer to the lower boundary. Prices outside the range still yield a guaranteed base APR—typically higher than bullish versions.
Bearish Shark Fin: Example Breakdown
- Subscription amount: 1,000 USDT
- APR range: 2% (basic) to 19% (maximum)
- Term: 7 days
- BTC price range: $18,000 – $21,000
Scenario 1: Price Below Range
- Expiration price: $17,000
- Below $18,000 → outside range.
- You earn the basic APR of 2%.
Earnings:
1,000 × 2% × (7 / 365) = 0.384 USDT
Scenario 2: Price Within Range
- Expiration price: $19,500
- Inside $18,000–$21,000 → eligible for variable APR.
- Assume payout APR is 11.5% due to position in mid-to-lower range.
Earnings:
1,000 × 11.5% × (7 / 365) = 2.205 USDT
Scenario 3: Price Above Range
- Expiration price: $24,000
- Above $21,000 → outside range.
- You still earn the basic APR of 2%.
Earnings:
1,000 × 2% × (7 / 365) = 0.384 USDT

If the expiration price matches either the upper or lower boundary of the defined range, it is considered within range, making you eligible for a variable APR based on proximity to the target limit.
Can I withdraw my funds early?

How are APRs determined within the range?
The exact APR depends on where the settlement price falls within the range. The closer it is to the favorable end (top for bullish, bottom for bearish), the higher your return—up to the maximum advertised APR.
