Whether you're bullish or bearish on Bitcoin (BTC) or Ethereum (ETH), Shark Fin offers a structured way to generate returns in any market condition—without risking your initial investment. In this comprehensive guide, we’ll break down everything you need to know about Shark Fin, including how it works, how to maximize your earnings, and what makes it a smart choice for both new and experienced investors.

What Is Shark Fin by OKX?

Shark Fin is a capital-protected savings product that rewards users with competitive annual percentage yields (APY) when the underlying asset—such as BTC or ETH—expires within a predefined price range. It combines the safety of principal protection with the upside potential of market-based returns, making it ideal for risk-aware investors.

How Does Bullish Shark Fin Work?

Bullish Shark Fin is designed for investors who believe the price of BTC or ETH will rise or remain within a favorable range over the investment period. At the end of the term—typically 7 days—the final price of the asset determines your APY.

You earn the highest possible yield if the asset closes within the target price range. If it finishes below or above the range, you still receive a base APY, ensuring you never leave empty-handed.

Earnings Formula

Your total return is calculated using:

Subscription Amount × (1 + APY × [Term in Days / 365])

Let’s walk through a real example:

Scenario 1: Below Range (Bearish Outcome)

Settlement Price: $17,000 (below $18,000)
APY: 1% (base rate)
Earnings: 1,000 × 1% × (7/365) = 0.192 USDT

Scenario 2: Inside Range (Optimal Outcome)

Settlement Price: $19,500
APY Calculation:
Base APY + (Price Spread / Range Width) × (Max APY – Min APY)
= 1% + [(19,500 – 18,000) / (21,000 – 18,000)] × (18% – 1%)
= 1% + (1,500 / 3,000) × 17% = 9.5%
Earnings: 1,000 × 9.5% × (7/365) = 1.822 USDT

Note: Example for illustration only. Actual APY varies per product cycle.

Scenario 3: Above Range (Overperformance)

Settlement Price: $24,000 (above $21,000)
APY: 1% (base rate)
Earnings: Same as Scenario 1 — 0.192 USDT

Even when the market surges beyond expectations, your base return is preserved—perfect for cautious investors.

How Does Bearish Shark Fin Work?

Bearish Shark Fin is tailored for those anticipating a dip in BTC or ETH prices. Unlike traditional shorting, which carries unlimited risk, Bearish Shark Fin caps your downside while offering strong upside potential.

Again, your APY depends on where the asset settles at expiry:

Let’s examine an example:

Scenario 1: Below Range

Settlement Price: $17,000
APY: 2% (base rate)
Earnings: 1,000 × 2% × (7/365) = 0.384 USDT

Scenario 2: Inside Range

Settlement Price: $19,500
APY Calculation:
Max APY – [(Current Price – Lower Bound) / Range] × (Max – Min APY)
= 19% – [(19,500 – 18,000)/3,000] × (19% – 2%)
= 19% – (1,500/3,000) × 17% = 19% – 8.5% = 10.5%
Earnings: 1,000 × 10.5% × (7/365) = 2.014 USDT

Scenario 3: Above Range

Settlement Price: $24,000
APY: 2%
Earnings: Same as Scenario 1 — 0.384 USDT

This structure rewards moderate declines or sideways movement—ideal for volatile markets.
