Turn weather exposure into market advantage

Weather risk analytics serves energy traders, risk managers, and portfolio managers across the full weather derivatives workflow.

Weather risk pricing

Weather risk pricing & analytics

Weather risk can’t be captured by static climatological averages. Professional markets need the full shape of the underlying distributions. Weather risk analytics supports multi-variable indices — including temperature, precipitation, snowfall, wind, solar irradiance, and custom energy-linked parameters — to mirror physical and financial exposure.

Models are built on quality-controlled surface observations and reanalysis data. Detrending separates structural climate trends and station relocations from short-term noise. Rigorous automated and manual data cleaning pipelines segregate structural climate trends and station relocations from high-frequency noise using advanced detrending algorithms.

Monte Carlo simulations show the full range of possible outcomes, and bias-corrected ensemble forecasts sharpen the short- and medium-term view. These scenarios feed directly into derivative pricing: burn cost, Greeks such as delta, and loss exceedance curves. The result: risk priced the way it’s actually realized.

Portfolio risk intelligence

Portfolio risk intelligence

Managing a weather risk portfolio takes continuous visibility across every active position. Live deal booking and real-time P&L set the baseline, while Daily VaR, Expiry VaR and Greek sensitivities quantify exposure across every instrument.

Weather and energy events are non-linear and spatially linked, so portfolio dependencies are modeled with copulas rather than simple correlation matrices. This captures tail dependencies and cross-regional contagion during extreme events. Counterparty credit risk is tracked too: potential future exposure and current exposure are monitored against credit limits, taking collateral and netting sets into account.

Concentration risks are surfaced early, and diversification benefits can be weighed across stations, zones and energy-linked asset classes. Hedging and trading strategies are evaluated with stochastic dominance and full distribution profiling, not mean-variance metrics alone. The result: a clear basis for balancing risk, capital and return.

Settlement lifecycle

Settlement lifecycle & audit governance

From final weather observation to final cash settlement, the platform enforces an uncompromised, automated operational lifecycle. Verified observational data and settlement indices automatically trigger precise calculation pipelines. The system processes complex payout functions, generates batch invoicing, and structures multi-currency cash-flow projections to ensure seamless clearing and settlement operations.

Granular user permissions, role-based access controls, and an immutable event log record every system action, valuation override, and trade modification. This guarantees complete lifecycle traceability from initial deal capture to final payment.

Designed to meet institutional governance standards, the platform provides audit-ready reporting to support global regulatory obligations. Comprehensive system exports, multi-currency conversion engines, and flexible data structures provide total transparency for complex, cross-border portfolios.

Frequently asked questions

Weather risk analytics covers pricing, portfolio risk, and settlement for climate risk contracts, from standard HDD and CDD hedges to baskets, multi-year strips, gas quantos, and renewable PPAs. It works across temperature, rainfall, wind, solar, and other environmental variables, with commodity and power prices held alongside weather data.

The platform uses Speedwell's quality-controlled weather and renewable-energy indices to structure, price, monitor, and settle climate risk contracts. Speedwell gridded data and forecast archives feed the database directly, and deal terms exchanged in the WeatherML format load straight from weatherXchange, ready to price.

Yes. Booked trades update P&L, Daily VaR, Expiry VaR, and simulations as new weather data and forecasts arrive, with update frequency set by your data feeds and reporting schedule. Middle office teams can stress-test the book with their own models without touching live trades.

Yes. Weather risk analytics brings contracts across locations, variables, and structures into one portfolio view, scaling to tens of thousands of weather sites. PCA, Markowitz charts, and stochastic dominance show aggregate exposure, concentrations, and diversification across global operations.

The database scales to tens of thousands of weather sites, down to minute-level data. The Data Manager automates historical and forecast feeds from multiple providers, and custom variables such as commodity prices, gas curves, and power price indices sit alongside weather data.
