The Central Bank of the Philippines has amended Section 362 of the Manual of Regulations for Banks to expand which guarantees can qualify as effective credit risk transfer arrangements under the rules on credit exposure limits to a single borrower. In addition to guarantees from already eligible guarantors, covered banks may recognize standby letters of credit, demand guarantees, and counter-guarantees issued between a bank's head office and branches in different jurisdictions, allowing the guaranteed portion of an exposure to take the guarantor's risk weight. Recognition of these intrabank guarantees is subject to a cap. The total credit risk-weighted amount of exposures covered by head office and branch guarantees must not exceed 100 percent of the Philippine bank's outstanding total loan portfolio at the end of the preceding month. That amount must be calculated by applying the risk weight of the guaranteeing head office or branch to covered banking book exposures and or the credit equivalent amount of covered off-balance sheet exposures. The total loan portfolio comprises interbank loans receivable, loans and receivables from reverse repurchase with the central bank and other banks, and other loans and receivables, all gross of allowance for credit losses. The amendments also restate that where an exposure is covered by an eligible credit derivative, the protected portion takes the protection seller's risk weight. The circular takes effect 15 calendar days after publication in the Official Gazette or in a newspaper of general circulation.
