What is the HHI metric used for?

The Herfindahl-Hirschman Index (HHI) measures market concentration; a score over 2500 indicates high concentration, helping identify systemic risks in the supply chain.

What data sources does this skill use?

It uses a tiered approach starting with official sources like USGS and INSG for baselines, followed by company annual reports and financial statements for specific mine-level data.

Is this skill only for Indonesian nickel?

While it has deep structures for Indonesia due to its high market share, it can analyze any major nickel-producing country including the Philippines, Russia, Canada, and Australia.

Can it simulate specific policy changes?

Yes, the scenario engine allows you to model production cuts, quota changes (such as Indonesia's RKAB), and export rules with adjustable execution probabilities (defaulting to 50%).

How does it handle different units like wet ore versus nickel content?

The skill enforces 'Unit Enforcement' protocols, requiring all data to be converted to a standard nickel metal content (t_Ni_content) to prevent order-of-magnitude errors in analysis.

データサイエンスとML

Analyzes global nickel supply structures and quantifies market concentration risks through policy simulation and data-driven metrics.

The Nickel Concentration Risk Analyzer is a specialized tool designed for commodity analysts and researchers to evaluate the complexities of the global nickel market. By focusing on supply dominance—particularly in regions like Indonesia—the skill utilizes industry-standard metrics such as HHI and CR_n to quantify market risk. It enforces rigorous data standards, distinguishing between nickel metal content and raw ore, and enables users to simulate various policy scenarios, such as RKAB quota changes or export restrictions, to predict impacts on global supply balance and potential price volatility.
