# Liquidity Risk

**Nature of the Risk**

Liquidity risk arises when an asset cannot be bought or sold quickly without significantly impacting its market price. In the crypto space, this is exacerbated by:

* **Shallow liquidity pools, particularly among mid- and lower-cap tokens.** Many crypto assets outside the top-tier market caps have limited on-chain liquidity. Even modest trade sizes can produce significant price slippage, reducing execution efficiency, distorting index performance and eroding net asset value (NAV) precision.
* **Fragmented markets across DEXs and CEXs.** Token liquidity is often split across multiple decentralized and centralized venues, with differing pricing and depth. This complicates price discovery and increases the risk of inefficient trade execution.
* **Lack of institutional-grade market-making.** Unlike traditional finance, crypto lacks stable participation from institutional market makers. This leads to thin order books, wider spreads, and price sensitivity during normal trading activity.
* **High on-chain gas costs during volatile periods.** Network congestion during volatile events can drastically increase gas fees, delaying execution or making on-chain trades economically unviable.

If not properly accounted for, liquidity risk can lead to:

* **Misleading NAV calculations.** Price feeds that ignore slippage or fail to aggregate liquidity may produce NAV values that do not reflect real trading conditions.
* **Skewed index weights.** Illiquid tokens may be overrepresented in the index due to outdated or unfiltered market cap data, distorting true market exposure.
* **High execution costs for index entry/exit.** Users may face increased gas fees and slippage, eroding returns or reducing the efficiency of portfolio rebalancing.

**Liquidity Risk Mitigation at OLTA**

OLTA employs a proactive and data-driven approach to filter, adjust, and dynamically adapt to liquidity constraints in real time.

**1. Minimum Depth & Volume Requirements**\
Assets must meet baseline liquidity thresholds before index inclusion (e.g., $4M+ 24h volume, $100k+ order book depth at <1% spread).

**2. Multi-Venue Liquidity Aggregation**\
Liquidity is assessed across both centralized and decentralized venues to avoid skewed assessments from single-exchange anomalies.

**3. Exclusion of Friction-Prone Assets**\
Tokens with known withdrawal issues, bridge dependencies, or illiquid wrappers are excluded after review, preserving frictionless entry/exit for investors.

**4. Liquidity-Weighted Allocation Logic**\
Index construction logic may cap or downweight low-liquidity assets, even if eligible, to maintain a high overall execution score and minimize drag during rebalancing. This sits inside OLTA's broader weighting discipline, where a single asset is capped at 35 percent and a stablecoin at 15 percent, so no position can grow large enough that exiting it would itself move the market.

**5. Liquidity Buffering**\
A fund may hold a small allocation in the settlement currency to absorb routine mint and redeem flow without forcing trades into the underlying basket on every transaction. This lets day-to-day liquidity needs be met from the buffer, reserving market execution for scheduled rebalancing and larger flows where it can be timed and staged.

**6. Tiered Execution Routing**\
Liquidity is sourced first through tier-one institutional prime brokerage and major liquid venues, where depth is deepest and spreads tightest, with a decentralized exchange (DEX) fallback reserved for long-tail assets that lack centralized depth. Routing the bulk of volume through the deepest available liquidity is itself a liquidity-risk control, since it minimizes the price impact each fill carries back into NAV.

**Why This Matters**

Liquidity risk is where a well-designed index meets the friction of real markets. A basket can be diversified and correctly weighted on paper and still deliver a poor investor outcome if its constituents cannot be traded near their quoted price. By screening on depth and volume at inclusion, aggregating liquidity across venues, capping concentration and buffering flow, OLTA keeps the gap between modeled NAV and realized execution narrow, which is what allows positions to issue and redeem at NAV with confidence.
