2-year realised volatility

How far the two-year yield has actually moved over the trailing month, in annualised basis points. The front end reprices on the policy path, so this rises when the market is arguing about the next few meetings. It is measured in basis points rather than as a percentage return because the two-year sat near a tenth of a per cent for years, where a percentage return on a one basis point move reads as ten per cent. Backward-looking, and a substitute for the implied volatility index this product does not licence.

QuantNow Derived Research

Root mean square of the daily change in the two-year constant maturity yield over 21 sessions, in basis points, annualised by the square root of 252. Absolute changes rather than percentage returns, because a yield near zero makes a percentage return explode and an inflation-indexed yield below zero makes it undefined.
