Market value is not necessarily usable value #

Collateral eligibility depends on the permitted asset, concentration limits, valuation and pledge process. A haircut reduces the amount recognized against risk. If an eligible holding has market value V and haircut h, recognized value under the simplified calculation is V × (1 − h).

Both inputs can change. A market fall reduces V, while a higher haircut reduces the recognized fraction. Collateral correlated with the trading exposure can become less useful precisely when the position creates additional funding pressure.

Cash and non-cash meet different needs #

Clearing-member effective-deposit composition requirements and the broker’s treatment of a client’s collateral are distinct. Do not present a member-level cash proportion as an unconditional promise about what every client may finance. Obtain the provider’s current definition of cash-equivalent eligibility and collection rules.

Premium payments, settled losses and charges can require usable cash even when adequate non-cash collateral exists for a margin calculation. A total resource comparison can therefore hide a separate cash shortfall.

Keep assumptions visible in the worksheet #

The margin worksheet allows an entered cash-component percentage for the scenario rather than promising a universal client rule. It compares both total recognized resources and an assumed minimum cash need. The larger gap is a planning estimate, not an official collection determination.

Pending pledge credit, a non-eligible security or a provider-specific concentration cap is not modeled. Avoid planning on collateral that has not actually been accepted. A stress test should allow for both lower market value and a larger haircut.

Decision lab: A haircut can create a shortfall without a trade #

If fictional collateral worth ₹1,00,000 receives a 20% haircut, eligibility is ₹80,000. At 30%, it becomes ₹70,000 before any price fall. Simultaneous market declines can reduce both the collateral value and the value of the positions it supports.

Stress price, eligibility and a cash debit together. Identify what can be transferred by the due time rather than counting resources that exist elsewhere but cannot arrive. Treat cash-component assumptions as inputs to verify, not universal platform rules.

Hypothetical worked example

Enough total value, but not enough cash

A hypothetical margin requirement is ₹1,00,000. Cash is ₹20,000 and collateral market value ₹1,00,000 with a 20% haircut, giving ₹80,000 recognized collateral. Total resources appear to match the margin.

If the scenario also assumes that ₹50,000 must be in cash, the cash gap is ₹30,000 despite zero total-resource gap. A separate ₹5,000 premium payable would increase the cash need further.

The 50% scenario is an input, not a statement of every client’s policy. Check accepted collateral, actual available cash and current provider requirements before drawing any operational conclusion.

Common mistakes

Adding unapproved collateral at full market value.
Assuming sufficient total collateral eliminates the need for premium or loss-settlement cash.

Check your understanding

With value ₹1,00,000 and a 20% haircut, what is recognized value under the simple model?

Can you defend the reasoning?

Before moving on, answer the self-check in your own words and write why each alternative fails. Use the worked example to test that explanation. Then apply it in the module research task; keep the assumptions and the evidence that could change your answer.
