Volatility surface calibration with diagnostics.

FerroRisk calibrates volatility surfaces as production inputs: fitted, diagnosed, and ready for Greeks, spreads, chain analytics, and scenarios.

Why this needs one shared risk path

!

Surface fits can look smooth while violating quality expectations or hiding poor quote coverage.

!

Downstream analytics are brittle when the fitted surface is not tied to diagnostics.

!

Products need a surface contract they can trust across contracts, chains, and spread analytics.

How FerroRisk handles it

01

Solve and normalize inputs

Market quotes move through IV and forward recovery before fitting.

02

Fit the model family

SVI, SSVI, and SABR workflows produce surfaces with explicit diagnostics.

03

Use the surface downstream

Calibrated surfaces feed local volatility, Greeks, spread pricing, and chain-level risk views.

What makes this FerroRisk-shaped

Public docs include surface calibration and smile panel readout workflows.

The home page names SVI, SSVI, SABR, and Dupire local-vol extraction.

Fit quality is part of the contract, not just a visualization.

Common concerns

Does FerroRisk only fit one surface model?

No. The public positioning covers SVI, SSVI, and SABR calibration workflows.

Can fitted surfaces feed spread products?

Yes. FerroSpread explicitly builds over the FerroRisk IV surface.
