Answer: Since both banks' spreads increased, the CVA on both sides of the contract will be higher.

The correct answer is C, which states that since both banks' spreads increased, the Credit Valuation Adjustment (CVA) on both sides of the contract will be higher. This is because the credit spreads for both HIP and ADB have increased due to the downgrades, indicating a higher perceived credit risk for both parties. The increase in credit spreads suggests that there is a greater likelihood of default, which in turn leads to a higher CVA. The CVA is a measure of the risk that a counterparty will default on its obligations under a financial contract. As the credit risk increases, so does the CVA, reflecting the additional cost of protecting against this risk. The other options are incorrect for the following reasons: A is incorrect because the increase in HIP's spread does not necessarily mean that HIP's Debt Valuation Adjustment (DVA) will increase. The DVA is related to the credit risk of the bank itself, not the counterparty, and is used to value the bank's own debt. B is incorrect because it incorrectly associates the increase in HIP's spread with an increase in HIP's CVA and a decrease in ADB's CVA. The increase in spreads affects both parties' CVA, not just one. D is incorrect because it suggests that the DVA on both sides will be lower, which is not supported by the information provided. The increase in credit spreads would actually lead to a higher DVA for both parties, as it reflects a higher cost of hedging against their own credit risk. The explanation is based on the principles outlined in Jon Gregory's "The xVA Challenge: Counterparty Credit Risk, Funding, Collateral, and Capital, 4th Edition" and "Stress Testing: Approaches, Methods, and Applications," edited by Akhtar Siddique and Iftekhar Hasan. These references discuss the calculation of DVA and the role of stressing DVA in stress testing credit risk.
