XVA: Other Value Adjustments (DVA, FVA, KVA, ColVA, MVA, LVA)

In my previous article, I had attempted to describe CVA (under XVA). In a derivative financial transaction, that a bank does, the value of the position is not impacted by creditworthiness of counterparty alone. There are other factors too.

Each XVA component addresses different risks and costs related to the valuation of derivatives. Together, these adjustments ensure that derivatives are priced more accurately, reflecting the true risks and costs that banks face.

Each of these factors are covered in XVA

1. DVA: Accounts for your own risk of not being able to pay your obligations.
2. FVA: Reflects the extra cost of funding a derivative position.
3. KVA: Represents the cost of holding regulatory capital for safety.
4. MVA: Captures the cost of posting collateral for a deal.
5. ColVA: Regulators ran out of letters. So that used "Col". ColVA Adjusts for the value of collateral posted or received.
6. LVA: Deals with the cost of unwinding positions in illiquid markets.

Let us attempt to describe each of the above in a language that common reader can understand (as hardcore risk professional either already knows it OR understands regulary guidelines already).

DVA: Debt Value Adjustment

DVA is about your own credit risk. If you're a bank and owe money on a derivative, DVA accounts for the fact that you might not be able to pay everything back if you run into financial trouble. This is in contrast to CVA where the counterparty may default.

Analogy:

Imagine you owe a friend money, but there's a chance you might not be able to repay the full amount. Your friend, aware of this risk, assumes that you might not pay the full amount. DVA is the "discount" on the amount you owe, reflecting the risk that you might default.

Example in Investment Banking:

In a derivative contract, a bank owes money to a counterparty. If the bank's credit risk worsens (e.g., it is downgraded), the value of the bank’s liabilities decreases because there’s a chance it might default. This is beneficial for the bank because its debt obligations are lower in value.

Regulatory Requirement:

Regulators require banks to account for their own credit risk in the valuation of liabilities to ensure that financial statements accurately reflect the likelihood of default. This is usually done through adjustments like DVA, as part of Basel III requirements on counterparty risk and own credit adjustments.

FVA: Funding Value Adjustment

FVA reflects the cost of funding a derivative position. Banks need money to cover the costs of entering into derivative contracts, and if they borrow money at a rate higher than the risk-free rate, FVA accounts for this extra cost.

Analogy:

Imagine you take out a loan with an interest rate higher than the bank’s prime rate. You end up paying more for the loan than you initially thought. FVA reflects this extra cost a bank incurs when funding derivative transactions at rates higher than the risk-free rate.

Example in Investment Banking:

When a bank enters a derivative position, it might need to borrow money to fund its side of the transaction. If the cost of borrowing is higher than the risk-free rate, the bank incurs extra funding costs, which are accounted for in the FVA.

Regulatory Requirement:

Under Basel III, regulators expect banks to consider the cost of funding derivative positions, especially when the funding is not at the risk-free rate. This helps in ensuring accurate financial reporting and capital adequacy in managing derivative exposures.

KVA: Capital Value Adjustment

KVA represents the cost of holding capital to comply with regulatory requirements. Banks are required to keep a certain amount of money aside (capital) in case things go wrong. KVA reflects the cost of setting aside this capital.

Analogy:

Think of KVA like a savings account you can't touch. You have to set aside a portion of your income as a safety net for emergencies. This capital is required but reduces your available spending money. KVA reflects the cost of setting aside this regulatory capital.

Example in Investment Banking:

Banks are required to hold capital against potential losses from derivative exposures. This capital has a cost because the bank could otherwise use it for other profitable ventures. KVA captures this opportunity cost.

Regulatory Requirement:

Basel III requires banks to hold sufficient capital against risky assets, including derivatives, to absorb potential losses. The KVA accounts for the cost of holding this capital, which banks must factor into their derivative pricing models.

MVA: Margin Value Adjustment

MVA is the cost of posting collateral (margin) to cover potential losses in a derivative deal. It’s like a deposit you give to make sure you can handle any potential losses.

Analogy:

Imagine you rent an apartment and need to put down a security deposit. You can’t use that money for anything else, and it costs you because you lose out on other opportunities. MVA is the cost of having to post collateral in derivative trades.

Example in Investment Banking:

When entering a derivative contract, banks often post collateral (initial or variation margin) to mitigate counterparty risk. The cost of tying up cash or securities as collateral is captured by MVA, representing the opportunity cost of not being able to use that collateral elsewhere.

Regulatory Requirement:

Under regulatory frameworks like EMIR or Dodd-Frank, banks must post collateral for certain derivative transactions. Regulators expect banks to account for the costs of these margin requirements in their valuation adjustments.

ColVA: Collateral Value Adjustment

ColVA takes into account the benefit or cost of collateral that’s posted or received during the derivative transaction. It reflects how collateral agreements affect the value of a derivative, depending on whether you’re giving or receiving collateral

Analogy:

It’s like having a friend borrow money from you and giving you something valuable (collateral) as a security. If they default, you can sell the collateral. ColVA reflects how the value of the collateral impacts the overall deal.

Example in Investment Banking:

Collateral agreements between counterparties impact the value of a derivative. If the collateral is high-quality and can be easily liquidated, the risk is lower, which could reduce the derivative's overall cost. Conversely, if collateral is risky, it increases the potential losses, affecting the valuation.

Regulatory Requirement:

Under Basel III and other regulations, collateral agreements need to be incorporated into the valuation of derivative contracts. The use of collateral reduces credit risk but comes with costs that need to be accounted for in ColVA.

LVA: Liquidity Value Adjustment

LVA represents the cost of liquidity risk. It accounts for how difficult or expensive it might be to trade or unwind a derivative position, especially in markets where there aren't many buyers or sellers.

Analogy:

Imagine trying to sell a rare collectible item in a small market. It’s difficult to find buyers, so you might have to accept a lower price. LVA accounts for this "liquidity risk" when trading derivatives in illiquid markets.

Example in Investment Banking:

In derivatives markets, certain positions are harder to exit because there may not be enough buyers or sellers. This is particularly true for complex or illiquid products. LVA reflects the cost or premium of unwinding these positions, as banks may need to offer a discount to find a counterparty.

Regulatory Requirement:

While LVA is not explicitly mandated by regulations, regulators expect banks to consider liquidity risk in their overall risk management. Basel III emphasises liquidity coverage ratios, and banks apply LVA to ensure the value reflects potential liquidity constraints.

Each XVA component addresses different risks and costs related to the valuation of derivatives. Together, these adjustments ensure that derivatives are priced more accurately, reflecting the true risks and costs that banks face.
