# Market & Collateral Security
Tydro contains market and collateral risk through isolation, conservative parameters, and caps
### Isolation contains failure
Tydro launches with isolated markets. A single collateral asset backs a single loan asset, and stress in that asset stays inside the market rather than spreading across the protocol. A new asset can be listed in its own market without changing the risk profile of existing ones. See [Isolated Markets](/ii.-core-concepts/markets/isolated-markets.md).
Where markets share margin through clusters, exposure is managed at the cluster level with its own parameters and caps, so correlation is accounted for. See [Clusters and Pools](/ii.-core-concepts/markets/clusters-and-pooled-markets.md).
### Parameters as controls
Risk parameters are the protocol's first line of defense against a falling market.
* Loan-to-value and liquidation threshold set the borrowing limit and the liquidation point, with a buffer between them. Conservative values leave more room before a position is at risk.
* The liquidation engine closes unhealthy positions automatically and permissionlessly, which keeps markets backed by sufficient collateral. See [Liquidations](/ii.-core-concepts/liquidations-and-risk-management.md).
* Caps limit total supply and borrowing in a market, which contains concentration and lets exposure scale in controlled steps.
These values are set through underwriting before a market launches, and adjusted as conditions change. See [Asset Underwriting](/vi.-security/security-overview/economic-security/asset-underwriting.md) and [Risk Parameters](/ii.-core-concepts/risk-paramaters.md).
### Active adjustment
Because markets are mutable, parameters respond to conditions. If volatility rises, the Risk Steward can lower LTV or tighten caps within approved bounds to protect existing positions, without waiting for a full governance cycle. If a threat appears, the Guardian can pause the market in the same step. See [Governance](/ii.-core-concepts/protocol-governance.md).
{% hint style="info" %}
Conservative parameters and caps limit how much can go wrong in a market and how fast. They are sized through underwriting and monitored continuously.
{% endhint %}
For the residual risk these controls reduce, see [Market and Collateral Risk](/v.-risk/risk-types-and-overview/market-and-collateral-risk.md) and [Liquidation Risk](/v.-risk/risk-types-and-overview/liquidation-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/vi.-security/security-overview/technical-security/market-and-collateral-security.md?ask=&goal=
```
`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.
