The Credit Valuation Adjustment is the adjustment that reflects the risk that a derivative's counterparty defaults before maturity. It reduces the value of the derivative by that expected loss and also carries its own regulatory capital charge under the Basel framework.

Why is it so costly to calculate?

Because it requires simulating the portfolio's future exposure by Monte Carlo: thousands of scenarios × multiple dates × repricing of every trade, plus sensitivities. That is millions of valuations that need HPC infrastructure to be solved within operational timeframes.

How does it relate to FRTB and Basel?

CVA risk has its own capital framework under Basel (revised in document BCBS d507) and shares calculation infrastructure with FRTB. Optimising the XVA grid usually benefits market risk computation as well.

XVA — derivatives valuation adjustments (CVA, DVA, FVA…)

XVA groups together the valuation adjustments that correct the price of an OTC derivative to reflect what the "risk-free" price ignores: counterparty credit risk, the cost of funding the position, the cost of regulatory capital and the cost of collateral. Calculating XVA on a real portfolio is one of the most demanding computational problems in investment banking.

The main adjustments

CVA (Credit Valuation Adjustment) — the risk that the counterparty defaults.
DVA (Debit VA) — the same risk seen from the institution's own perspective.
FVA (Funding VA) — the cost of funding the uncollateralised position.
KVA (Capital VA) — the cost of the regulatory capital the trade consumes.
MVA (Margin VA) — the cost of posting initial margin / collateral.

Why it is an HPC challenge

XVA requires Monte Carlo simulation of future exposure (EPE/PFE) across the entire portfolio, repricing thousands of trades in each scenario and date, plus the sensitivities needed to manage the risk. That translates into millions of valuations that are only viable on properly sized grid/HPC infrastructure (e.g. IBM Spectrum Symphony), with calculation times kept under control to support intraday operation.
