NtSaaS: The Next Generation of Financial Risk Management

Delivering high-performance VaR measurement and ALM capabilities on a secure Software-as-a-Service platform

OUR PROVEN SOLUTIONS, EVOLVED FOR SaaS

NtSaaS® for ALM

Modern ALM (Asset Liability Management) should inherently be a forward-looking discipline. However, many current systems rely on static models or approximations, which limit the accuracy of future projections.

Our ALM solution fundamentally breaks through these constraints. Reflecting the insights of financial practitioners, this platform can dynamically simulate future balance sheets while maintaining the integrity of double-entry bookkeeping.

In IRRBB (Interest Rate Risk in the Banking Book) management, in addition to BPV, it calculates ΔEVE (change in economic value) and ΔNII (change in net interest income), enabling consistent evaluation from short-term earnings to long-term value.

Furthermore, from an ERM perspective, it calculates future B/S and P/L (under both current accounting and fair value bases) and derives various KPIs and KRIs in line with the PDCA cycle. Through flexible integration with economic and interest rate scenarios, it supports strategic planning and risk assessment from multiple angles.

NtSaaS® for Market and Credit Risk

The greatest risk faced by financial institutions is not the individual existence of market risk or credit risk, but the fact that these risks are intricately intertwined and sometimes interact in ways that are difficult to detect.

Our integrated VaR platform enables risks to be captured from a single, unified perspective. Using a bottom-up calculation approach, it visualizes the true correlation structure inherent in a portfolio. In addition, through simulations based on multiple stress scenarios, it quantitatively assesses risk resilience under extreme market conditions.

This provides transparent and highly reliable risk information necessary for optimizing capital allocation and making strategic decisions, thereby further strengthening financial institutions’ risk management frameworks.
