As noted, we aim to run capital modelling methods that align with best practice, and can choose models that address our balance sheet risks. As a result we are focused on evolving our modelling of market, credit and operational risk, and are less concerned about liquidity elements (as we invest heavily in high-quality liquid assets).
Note that, together, these market prices imply that the five year-five year forward real interest rate is around 1 percent. The 10 year-10 year forward real interest rate is only slightly higher. Why have real interest rates fallen so much? At one level, the answer is obvious: monetary policy.
