Letter 49

​​​​​Lending Limits Applicable to Credit Exposure on Derivative Transactions​

Effective January 21, 2013, Section 611 of the Dodd-Frank Act prohibits state chartered banks from engaging in derivative transactions unless "the law with respect to lending limits, of the State in which the insured State bank is chartered takes into consideration credit exposure to derivative transactions."

he Division of Banking has determined that the language in Wisconsin's lending limit statutes, by incorporating the use of the Willis "liabilities" and "extension of credit" are broad enough include derivatives.  This interpretation is consistent with the treatment of derivatives in Banking Letter 48 relating to the pledging of assets.

Under Dodd-Frank, a derivative transaction "includes any transaction that is a contract, agreement, swap, warrant, note, or option that is based, in whole or in part, on the value of any interest in, or any 
quantitative measure or the occurrence of any event relating to, one or more commodities, securities, currencies, interest or other rates, indices, or other assets."

Effective January 21, 2013, the Division of Banking will consider the credit exposure of derivative 
transactions when computing lending limits under the provisions of Wis. Stat. s. 214.54​ and Wis Stat. s. 221.0320​.

The potential future credit exposure arising from a derivative transaction shall be determined for legal lending purposes. The potential future credit exposure is calculated using the Remaining Maturity 

The Remaining Maturity Method shall equal the greater of zero or the sum of the current mark-to market value of the derivative transaction added to the product of the notional amount of the 
transaction, the remaining maturity in years of the transaction, and a fixed multiplicative factor determined by reference to Table 1, below.

A bank enters into a five year swap for $10,000,000
on LIBOR on 1/1/20xx, agreeing to pay a floating rate three month LIBOR in exchange for receipt of a  2.00%  fixed rate. On 1/1/20xx +3 years the fixed portion of the LIBOR is valued at 0.50% and the bank has a positive market value of $250,000 (the counterparty would owe the bank if the swap was terminated).

The calculation of the future credit exposure would be:

$250,000 (market value owed the bank) + ($10,000,000 (notional value) * 2 (remaining maturity in years) * 0.015 (multiplicative factor)) = $550,000 (future credit exposure)
