Powerful new modeling solution improves risk management

6 x faster
Risk calculations reduced from hours to minutes

Challenges

On a daily basis, Ericsson’s central treasury calculates and tracks Value at Risk (VaR) for its portfolios of financial instruments. Until recently, Ericsson was using a proprietary overnight batch process to estimate the co-variance matrix for the VaR calculation. But the application was proving inflexible – it took seven hours to run and could not be easily re-configured and re-run if errors came to light. Technical support for the proprietary software was also lacking. Tomas Lourie, treasury risk manager at Ericsson says: “It was clearly time for a fresh start to remove all these obstacles.” So the challenge was to find a flexible and transparent solution.

The requirement was to speed up the process of extracting prices from its Wallstreet Suite treasury management system and performing the co-variance matrix estimation, giving the treasury more confidence in its ability to do financial modeling rapidly at the point of need.

Using OmniFi we can correct and re-calculate co-variance in no time. We are not dependent on overnight batch processing, which is a big advantage.

Solution

Ericsson was already a long-term satisfied user of SkySparc’s Transaction HUB solution for straight-through processing of transactions made on bank electronic dealing platforms into the firm;s treasury management system.
“We knew SkySparc for solutions that work seamlessly with our treasury management system and for quality support,” says Lourie.
“OmniFi seemed like a great fit for our new need.” OmniFi is an integration and processing platform enabling fast integration of financial systems within a client’s environment. It is a very efficient platform for developing tailored solutions without the time-scales and costs usually associated with bespoke development.

In this case, Ericsson needed to extract prices from its treasury management system into a data matrix file, run the covariance matrix estimation analysis and feed the results back to. SkySparc built the calculation module required for this and tailored OmniFi to manage the data, perform the analysis and import the calculations back to the treasury system.

Results

Today Ericsson’s treasury has a process for calculating the VaR co-variance matrix with the speed, flexibility and transparency it needs to be fully confident it can always respond to the business environment.

With OmniFi, price extraction, covariance matrix calculation for 500,000 correlations and integration back into the database now take less than ten minutes. Using the old solution took seven hours. This massive efficiency improvement gives the risk management team far greater flexibility. “We can now easily re-run the process if we find some missing or incorrect prices,” says Lourie. “Using OmniFi we can correct and re-calculate co-variance in no time. We are not dependent only on overnight batch processing, which is a big advantage.”

OmniFi also gives Ericsson’s risk management team greater visibility of what data is being used and how the calculations are performed. For example, they can adjust initial parameters before each calculation process begins, such as the date range from which the solution will fetch historic data. “We can change things very easily if required,” says Lourie. “So we now feel comfortable that we have total control of this important risk management process. And given the responsiveness we have seen from SkySparc during the implementation, we’re confident that any future modifications or modeling requirements can also be accommodated within OmniFi.”

The new application was delivered within the required timeframes and budget by SkySparc’s consultants. The strong combination of systems development, quantitative statistics and financial markets expertise in the SkySparc team proved a winning combination for this project.
