Fixed Income: IR Hedging Matrix & Portfolio Analytics

Nowadays, it is common practice to utilize fixed income instruments to hedge against the unpredictable equity market. Yet fixed income instruments have their own interest rate risk that requires hedging as well.

Imagine’s interactive interest rate hedging tool, the IR Hedging Matrix, enables users to evaluate interest rate risks associated with any portfolio, book, or ledger, and returns the number of hedge contracts needed to hedge the interest rate risk.

Interest rate exposure and hedging contracts can be seen across all yield curves associated with a holding’s pricing environment. In the illustration below, we choose the Risk Curve “AUD-GOVT”  and then right click Load Risks => Default, as below.

The first row displays the Dv01 of the entire portfolio and the corresponding number of contracts needed to make the portfolio Dv01-neutral (for the respective Risk Curve).

The second column, dHtot(R), is the risk exposure per instrument that makes up the yield curve. Since AU5YT=RR is the main contributor to the yield risk (-569.11 out of -687.17), by shorting 1.41 units of the AU5YT=RR bond contract, the portfolio manager can hedge the majority of the portfolio’s AUD-GOVT Dv01 risk. The fact that the Dv01 risk primarily comes from AU5YT=RR is intuitively in line with the maturity of the treasury bond being analyzed: AUGV 2.25% 11/22.

However, considering that it’s not conventional to sell 1.41 units of the said hedging instrument, the user can override the optimal hedging units, initially calculated from the Recalc Hedge option, by directly keying in the intended hedging units in the first row for each instrument. In the example below, the unit of AU5YT=RR bond was changed to -1.00 and the hedging matrix automatically calculated the portfolio’s Dv01 risk being hedged as 522.00 (shown in dHtot(R)). The user can always return to optimal hedging scenario by right clicking and selecting Recalc Hedge.

To complement the IR hedging tool, users are able to customize calculations based on Imagine’s Fixed Income sensitivity analytics (such as Duration, Mod Duration, Convexity, Mod Convexity). Below is an illustration of a custom column built for this purpose.

In the example below, we look at a portfolio’s aggregate yield/duration/convexity calculation along with the contribution of each holding to the whole portfolio.

What’s more, Imagine is building a dedicated web portal – myImagine – to allow users access to its portfolio management solutions from any browser, smartphone, or tablet.  The same IR hedging matrix demonstrated in this article will be accessible in a portal as shown below:

Imagine’s Response to Negative Oil Prices

It was a historic moment to be remembered when crude oil plunged into negative price territory on Monday 20th April 2020. Imagine’s Data, Technical, Development and Professional Services teams stood ready to assist users in ensuring they continued to correctly calculate risk metrics across commodity trading books. While negative prices are not a new thing in financial markets, it was the first time for crude oil to exhibit such behaviour. Standard pricing models (Black Scholes) for commodity future options are not designed to handle negative underlying prices. As such, Imagine applied an ‘early roll’ of the front month contract of May crude to the June expiry as the negative settle price was confirmed.
