The Vol 6. No. 1 Issue of the Numerix Journal highlights Numerix's achievements in two areas: the ongoing quantitative research and development which extends the functionality of our products, and the innovative Python-based approach to CrossAsset templates. The issue presents papers on the following topics: multi-curve modeling for tenor basis spreads, a new arbitrage-free parametric volatility surface, and STIRs and OIS futures in the Hull-White model. This journal concludes with an article on next generation python-based templates, and introduces the concept of a CrossAsset worker process.
