Notice
Summary
The National Securities Clearing Corporation (NSCC) wants to update its rules to collect money during the day to cover risks better, following new government standards. This change affects financial firms that use NSCC’s services and aims to keep the system safer without causing big money surprises. The new rules could start soon after public feedback, helping everyone stay on top of risk in real time.
Analyzed Economic Effects
6 provisions identified: 2 benefits, 3 costs, 1 mixed.
15‑Minute Intraday Margin Monitoring & Calls
NSCC will monitor member exposures every 15 minutes (generally between 10:00 a.m. and 4:30 p.m. Eastern Time) and may collect intraday margin payments (Intraday Mark‑to‑Market Charge and Intraday Volatility Charge) when defined risk thresholds are met.
Specified Thresholds for Intraday Charges
Intraday Mark‑to‑Market Charges may be imposed when the mark‑to‑market difference meets or exceeds 80% of a Member's start‑of‑day volatility charge. Intraday Volatility Charges may be imposed when the intraday volatility difference meets or exceeds 100% and the amount to collect would be greater than $250,000.
Authority to Lower Thresholds for Specific Members
NSCC would be able to reduce intraday margin thresholds for an individual Member or groups of Members if NSCC determines it necessary to protect itself and its Members due to market conditions or a Member's financial or operational capabilities.
Use of Baseline ETF Calculation When Inputs Are Unavailable
If data inputs for the ETF Create/Redeem Calculation are unavailable or unreliable, NSCC may use the Baseline Calculation to determine the Margin Liquidity Adjustment (MLA) charge for certain equity ETFs; NSCC describes the Baseline Calculation as its existing, conservative alternative.
Possible Waiver of Intraday Volatility Charge
NSCC may waive an Intraday Volatility Charge in exigent circumstances if it determines a waiver is necessary to protect NSCC, participants, investors, and the public interest, or if NSCC can address the risk without collecting the charge.
Documentation & Public Posting of Monitoring Frequency
NSCC will document decisions not to collect intraday margin charges and will post on its public website the timing and frequency with which it monitors and recalculates intraday exposures.
