Title 12Chapter VISubchapter BPart 628Subpart D → §628.37


Title 12: Banks and Banking
PART 628—CAPITAL ADEQUACY OF SYSTEM INSTITUTIONS
Subpart D—Risk-Weighted Assets—Standardized Approach


§628.37   Collateralized transactions.

(a) General. (1) To recognize the risk-mitigating effects of financial collateral, a System institution may use:

(i) The simple approach in paragraph (b) of this section for any exposure.

(ii) The collateral haircut approach in paragraph (c) of this section for repo-style transactions, eligible margin loans, collateralized derivative contracts, and single-product netting sets of such transactions.

(2) A System institution may use any approach described in this section that is valid for a particular type of exposure or transaction; however, it must use the same approach for similar exposures or transactions.

(b) The simple approach—(1) General requirements. (i) A System institution may recognize the credit risk mitigation benefits of financial collateral that secures any exposure.

(ii) To qualify for the simple approach, the financial collateral must meet the following requirements:

(A) The collateral must be subject to a collateral agreement for at least the life of the exposure;

(B) The collateral must be revalued at least every 6 months; and

(C) The collateral (other than gold) and the exposure must be denominated in the same currency.

(2) Risk-weight substitution. (i) A System institution may apply a risk weight to the portion of an exposure that is secured by the fair value of financial collateral (that meets the requirements of paragraph (b)(1) of this section) based on the risk weight assigned to the collateral under §628.32. For repurchase agreements, reverse repurchase agreements, and securities lending and borrowing transactions, the collateral is the instruments, gold, and cash the System institution has borrowed, purchased subject to resale, or taken as collateral from the counterparty under the transaction. Except as provided in paragraph (b)(3) of this section, the risk weight assigned to the collateralized portion of the exposure may not be less than 20 percent.

(ii) A System institution must apply a risk weight to the unsecured portion of the exposure based on the risk weight assigned to the exposure under this subpart.

(3) Exceptions to the 20-percent risk-weight floor and other requirements. Notwithstanding paragraph (b)(2)(i) of this section:

(i) A System institution may assign a 0-percent risk weight to an exposure to an OTC derivative contract that is marked-to-fair on a daily basis and subject to a daily margin maintenance requirement, to the extent the contract is collateralized by cash on deposit.

(ii) A System institution may assign a 10-percent risk weight to an exposure to an OTC derivative contract that is marked-to-fair value daily and subject to a daily margin maintenance requirement, to the extent that the contract is collateralized by an exposure to a sovereign that qualifies for a 0-percent risk weight under §628.32.

(iii) A System institution may assign a 0-percent risk weight to the collateralized portion of an exposure where:

(A) The financial collateral is cash on deposit; or

(B) The financial collateral is an exposure to a sovereign that qualifies for a 0-percent risk weight under §628.32, and the System institution has discounted the fair value of the collateral by 20 percent.

(c) Collateral haircut approach—(1) General. A System institution may recognize the credit risk mitigation benefits of financial collateral that secures an eligible margin loan, repo-style transaction, collateralized derivative contract, or single-product netting set of such transactions by using the standard supervisory haircuts in paragraph (c)(3) of this section.

(2) Exposure amount equation. A System institution must determine the exposure amount for an eligible margin loan, repo-style transaction, collateralized derivative contract, or a single-product netting set of such transactions by setting the exposure amount equal to max:

{0, [(∑E—∑C) + ∑(Es x Hs) + ∑(Efx x Hfx)]}

Where:

∑E = for eligible margin loans and repo-style transactions and netting sets thereof, the value of the exposure (the sum of the current fair values of all instruments, gold, and cash the System institution has lent, sold subject to repurchase, or posted as collateral to the counterparty under the transaction (or netting set)); and

∑E = for collateralized derivative contracts and netting sets thereof, the exposure amount of the OTC derivative contract (or netting set) calculated under §628.34(c) or (d).

∑C = the value of the collateral (the sum of the current fair values of all instruments, gold and cash the System institution has borrowed, purchased subject to resale, or taken as collateral from the counterparty under the transaction (or netting set));

Es = the absolute value of the net position in a given instrument or in gold (where the net position in the instrument or gold equals the sum of the current fair values of the instrument or gold the System institution has lent, sold subject to repurchase, or posted as collateral to the counterparty minus the sum of the current fair values of that same instrument or gold the System institution has borrowed, purchased subject to resale, or taken as collateral from the counterparty);

Hs = the fair value price volatility haircut appropriate to the instrument or gold referenced in Es;

Efx = the absolute value of the net position of instruments and cash in a currency that is different from the settlement currency (where the net position in a given currency equals the sum of the current fair values of any instruments or cash in the currency the System institution has lent, sold subject to repurchase, or posted as collateral to the counterparty minus the sum of the current fair values of any instruments or cash in the currency the System institution has borrowed, purchased subject to resale, or taken as collateral from the counterparty); and

Hfx = the haircut appropriate to the mismatch between the currency referenced in Efx and the settlement currency.

(3) Standard supervisory haircuts. (i) A System institution must use the haircuts for fair value price volatility (Hs) provided in Table 1 to §628.37, as adjusted in certain circumstances in accordance with the requirements of paragraphs (c)(3)(iii) and (iv) of this section:

1The market price volatility haircut in Table 1 to §628.37 are based on 10-day holding period.

2Includes a foreign PSE that receives a 0-percent risk weight.

(ii) For currency mismatches, a System institution must use a haircut for foreign exchange rate volatility (Hfx) of 8 percent, as adjusted in certain circumstances under paragraphs (c)(3)(iii) and (iv) of this section.

(iii) For repo-style transactions, a System institution may multiply the standard supervisory haircuts provided in paragraphs (c)(3)(i) and (ii) of this section by the square root of 12 (which equals 0.707107).

(iv) If the number of trades in a netting set exceeds 5,000 at any time during a quarter, a System institution must adjust the supervisory haircuts provided in paragraphs (c)(3)(i) and (ii) of this section upward on the basis of a holding period of 20 business days for the following quarter except in the calculation of the exposure amount for purposes of §628.35. If a netting set contains one or more trades involving illiquid collateral or an OTC derivative that cannot be easily replaced, a System institution must adjust the supervisory haircuts upward on the basis of a holding period of 20 business days. If over the 2 previous quarters more than two margin disputes on a netting set have occurred that lasted more than the holding period, then the System institution must adjust the supervisory haircuts upward for that netting set on the basis of a holding period that is at least two times the minimum holding period for that netting set. A System institution must adjust the standard supervisory haircuts upward using the following formula:

Where:

TM = a holding period of longer than 10 business days for eligible margin loans and derivative contracts or longer than 5 business days for repo-style transactions;

HS = the standard supervisory haircut; and

TS = 10 business days for eligible margin loans and derivative contracts or 5 business days for repo-style transactions.

(v) If the instrument a System institution has lent, sold subject to repurchase, or posted as collateral does not meet the definition of financial collateral in §628.2, the System institution must use a 25-percent haircut for fair value price volatility (HS).
