Institutions have mastered methods to deal with Bitcoin price fluctuations, but the risk of market fluctuations caused by insufficient liquidity during the buying and selling process is still the core obstacle to large-scale allocation.

Funds can hedge price fluctuations through options and futures, but they cannot avoid slippage costs caused by thin order books, widening spreads, and rebalancing.

This highlights the importance of liquidity. It is not equivalent to transaction volume, but the market's ability to absorb transactions at a predictable cost. It needs to be measured from the multi-layered dimensions of spot order books, derivatives and ETFs, and stablecoin cash channels.

At the spot level, the core is transaction execution and liquidity replenishment capabilities. Although the bid-ask spread is easy to refer to, it may mask the problem of insufficient order volume. 1% market depth (the volume of tradable orders within 1% of the central price) is more valuable as a reference. Its decline will lead to greater fluctuations in the same transaction size and difficult to predict execution costs.

In addition, the speed of liquidity replenishment is the key to distinguishing market resilience, and there are time differences in liquidity. There are significant differences in depth and spread between active trading periods and conservative periods of market makers. Low depth near the integer mark will also intensify market sensitivity.

Derivatives and ETFs can transmit or alleviate spot market pressure. When spot trading volume shrinks, the concentrated leverage risk of perpetual contracts and futures becomes more prominent. The soaring financing rates and widening basis mean that positions are crowded. Subsequent forced liquidation of market orders will intensify slippage and gaps when liquidity is insufficient.

ETF provides dual liquidity markets of secondary (stock trading) and primary (subscription and redemption). Under normal circumstances, the value of the ETF can be kept consistent with the value of the position, helping investors to indirectly adjust their exposure; however, when the one-way capital flow is too large, pressure will still be transmitted to the spot market.

The cash liquidity channel dominated by stablecoins is easily overlooked, but it is a key prerequisite for institutional allocation. Institutions not only need Bitcoin liquidity, but also reliable cash and collateral channels that flow across platforms and can be integrated into the margin system. Spot and derivatives transactions mostly rely on stablecoin trading pairs and collateral.

Liquidity dominated by the regulatory system and stablecoins makes the liquidity of the crypto market partially affected by policies. There may be ample overall liquidity but insufficient liquidity available to institutions, pushing up execution costs.

To measure liquidity, you need to pay attention to the four core indicators:

(1) The 1% depth, best spread and standardized slippage of major trading venues are used to determine the expansion or contraction of liquidity.

(2) Spot financing interest rate and futures basis difference, perceived position congestion.

(3) ETF secondary market spread, trading volume and subscription and redemption data to evaluate its liquidity buffering effect.

(4) Stable currency liquidity and cross-platform concentration ensure reliable execution during market fluctuations.

If the indicators improve together, it will be easier for institutions to carry out large-scale transactions; if they worsen, institutions will be more cautious and rely on packaging tools and hedging strategies to avoid light trading periods.
