As we look back on the first quarter of 2022, returns across investable asset classes show some remarkably disparate results. The quarter was an unforgiving one for fixed income investors — bond markets suffered their biggest loss in more than 40 years, with Treasury markets sliding 5.6% and corporate bonds dropping almost 8%. After reaching new heights over the past two years, equity markets fell into correction territory and tech names that had shone so brightly during the early days of the pandemic dramatically pared their gains. Commodity markets, however, bucked the trend and meaningfully outperformed other asset classes — notching their best first quarter in the past 25 years. Looking across several of ICE’s benchmarks that represent some of these asset classes, the contrast is stark. The highlighted figures below also show that for some of these asset classes, the most recent results corresponded with either the best or worst first quarter returns in the past 25 years.

War, inflation and the lingering effects of the pandemic have preoccupied investors and market participants. The downturn has not been orderly, with volatility up significantly. Over the course of the quarter, we saw volatility rise meaningfully. The ICE BofA MOVE Index, which measures bond volatility, remains elevated — the index spent most of 2021 hovering in the 60s but recently jumped to highs, near 150, a level not seen since March 2020.

Against this backdrop, investors are seeking tools to help them manage their risk across various asset classes. Additionally, SEC Rule 18f-4 is a pressing concern for US fund market participants, with the August 19, 2022 implementation date quickly approaching. SEC Rule 18f-4 focuses on derivative risk and exposure, measuring across all asset classes held in the fund. Funds with derivatives exposures with >10% of NAV are required to run daily VaR calculations, weekly stress tests and model back-testing. For the rule, a minimum of three years of market data must be used to calibrate the models with portfolio 20-day 99% VaR remaining under either 200% of the designated reference benchmark portfolio or 20% of NAV. As the rule is broad and incorporates all asset classes held, historical data and sophisticated stress test methodology is necessary. On a summary level, the rule seeks to modernize the derivatives risk management framework for certain U.S. SEC-registered investment companies, including mutual funds (other than money market funds), ETFs, closed-end funds and business development companies.

VaR is a statistical measure of market risk of a specific security or a portfolio and helps investors quantify the potential losses they may be exposed to. It measures the amount of potential loss a portfolio is expected to have over a given confidence level and over a designated timeframe. Among other things, VaR is often used to help determine cash reserves that might be needed to cover unexpected portfolio losses, quantify how much short positions and derivatives increase or decrease a portfolio’s leverage, and optimize hedging strategies. The primary methods of calculating VaR include: Historical, Parametric and Monte Carlo simulation.

With the first quarter’s historically poor performance for fixed income now in the rearview mirror, it can be helpful to look back at just how some bonds fared. Using the ICE BofA Global Crossover Country Corporate & Government Index as a proxy for a risk seeking mixed asset portfolio, one can see the nature of the sell-off and how it played out at the constituent level.

Despite being issued by countries and/or their agencies, Sovereign and Quasi Sovereign bonds did not hold up much better than Corporate bonds, with many double-digit price declines observed for all categories. Additionally, bonds priced at or near par at the start the year, did not offer much solace either, as quite a few saw their values cut in half during the first quarter. In retrospect, the volatility and outsized market movements during the period illuminated the importance of prudent risk management.

To help understand the exposures and how a portfolio manager or investment team might manage the risks laid out in the introduction, we used a proxy portfolio (the ICE BofA Global Crossover Country Corporate & Government Index) and assumed it was a $1 billion fund, using index weights for the holdings sizes. We opted to use an HVaR version of the value-at-risk calculation, which incorporates a historical data input length (the length of observation used for calibration). ICE’s HVaR modeling can help a risk management team understand what the potential loss might have looked like over the 45-day period ended March 31, 2022, which would have captured most of the volatility in the marketplace and key moments leading up to and during Russia’s invasion of Ukraine through April 7. The HVaR analysis, at a 99% confidence interval, for an unhedged version of the portfolio (index weighted bond constituents only) showed a potential loss of $52.4 million over the 45-day period.

However, when adding short credit and interest rate derivatives positions to hedge a portion of this risk, a portfolio manager could potentially reduce that exposure significantly. ICE has the capability to calculate the VaR for portfolios comprising these instruments, as well as foreign exchange, commodity, and equity derivatives. For a more extensive look-through of the theoretical hedges that were applied, please refer to the figure above. Over the same time period, the HVaR for a hedged version of the portfolio improved by nearly $22 million. ICE’s solution allows users to calculate the VaR on a mixed portfolio of asset classes, making it easier for users to get a fuller picture of their exposure through a single tool.

In this use case, zooming into Historical VaR, a predetermined period is defined. Using the changes in market data in that period, the movements are simulated and translated to the current marketplace and extrapolations can be made about what those movements would look like today (incorporating new instruments, changes in securities, ratings, etc.). A simulation is then run, testing the month-to-month changes in a portfolio based on previous historical market movement with a landscape that reflects today’s market. Results display the likely performance of a portfolio if previous market events were to reoccur, exposing portfolio reactions.

Most VaR models do not take such a short-term view and generally use a three-year horizon for their calculations. The exercise above was to highlight the tumult that was felt across credit and interest rate markets last quarter. Many of the regulatory frameworks also require more extensive VaR time horizons and data history. Using a three-year time period, the HVaR for the portfolio fell considerably, and for an unhedged portfolio stood at $43.7 million, while one that used the same hedges as outlined above would have approximately $40.8 million at risk. The ICE Portfolio Analytics - Derivatives (“IPA - Derivatives”) application displays summary portfolio HVaR information in addition to position level metrics with “tail” values and dates, allowing for more granular risk management analysis.

If utilized correctly, VaR calculations may be able to expose securities or positions that could act as a catalyst and significantly harm the overall health and value of a portfolio. Identifying these positions may help risk managers and portfolio managers reduce the exposure and adjust hedges of vulnerable positions. ICE’s IPA-Derivatives platform also allows for deeper attribution level analysis at the portfolio constituent level. The IPA-Derivatives tool allows users to drill into what positions in particular are driving overall portfolio VaR, helping to identify outliers or concentrations that warrant attention. ICE’s tool also provides the historical data that is required for investment and risk management teams to meet those requirements.

In this example, the results across time periods change pretty dramatically. Over the 45-day window, the securities that were most impacted differed meaningfully from those over the three-year period. Egypt, for example, constituted one of the top 10 issuer countries with highest VaR contribution in the 45-day period but had extremely low correlation to other securities, suggesting that it was much more sensitive to the market volatility witnessed during the first quarter of 2022 than some of the other securities, which intuitively could be a function of the country’s heavy reliance on wheat imports from Russia and Ukraine.
