# Clusters and Pooled Markets

### Clusters

A cluster groups assets that move together, so one position can draw on several of them at once. Borrowing capacity reflects the combined collateral in the cluster, weighted by each asset's parameters, rather than one asset standing alone. This is cross-asset margin: post a mix of correlated collateral and borrow against the whole.

Each cluster sets its own parameters and caps, so exposure stays managed at the group level. Each asset is priced by its own oracle feed, and the cluster's combined collateral value updates as those feeds move.

Asset isolation and borrow configurations are managed using [Efficiency Mode (eMode)](/ii.-core-concepts/markets/efficiency-mode-emode.md).

### Pools

A pool widens the boundary further, sharing liquidity across a defined set of assets so suppliers and borrowers meet in one venue rather than many. Suppliers provide liquidity that any borrower in the pool can draw on, and borrowers gain access to deeper liquidity than a single market offers. Pools suit strategies where breadth of liquidity matters more than tight isolation.

### Comparison

| Dimension          | Isolated market                | Cluster                               | Pool                              |
| ------------------ | ------------------------------ | ------------------------------------- | --------------------------------- |
| Risk scope         | one collateral, one loan asset | a group of correlated assets          | a defined set sharing one venue   |
| Margin             | single-asset                   | cross-asset, shared                   | shared liquidity                  |
| Capital efficiency | lowest                         | higher                                | highest                           |
| Risk containment   | strongest                      | group level                           | broadest                          |
| Best suited to     | listing new or volatile assets | borrowing against correlated holdings | strategies needing deep liquidity |

### Choosing the right structure

Isolated markets keep risk inside one collateral asset. Clusters and pools relax that boundary on purpose, in exchange for capital efficiency across assets that already track each other. The cost of that efficiency is shared exposure: stress in one asset can reach the others in the same group. Tydro sizes caps and parameters per cluster to keep that exposure inside set limits.

{% hint style="info" %}
Correlated assets are not identical assets. If an asset in a cluster de-pegs or breaks from the group, shared margin can transmit that stress to other positions in the same cluster. See [Market and Collateral Risk](/v.-risk/risk-types-and-overview/market-and-collateral-risk.md).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.tydro.com/ii.-core-concepts/markets/clusters-and-pooled-markets.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
