The 9 Life Capitals

Money is one type of wealth. The Wealth School counts nine, which it calls the 9 Life Capitals: nine capital kinds, each defined by the characteristic human capacity that anchors it.

  1. Financial Capital — the capacity to acquire, preserve, allocate, mobilize, and steward economic resources across time.
  2. Intellectual Capital — the capacity to acquire, generate, organize, integrate, and apply knowledge, understanding, judgment, and wisdom.
  3. Social Capital — the capacity to create, access, participate in, and benefit from networks, communities, institutions, and collective trust.
  4. Relational Capital — the capacity to form, sustain, repair, deepen, and wisely navigate meaningful interpersonal relationships.
  5. Emotional Capital — the capacity to perceive, regulate, express, recover from, and constructively employ emotional experience in oneself and others.
  6. Life Force Capital — the capacity to generate, maintain, restore, and direct vitality, energy, health, resilience, and embodied agency.
  7. Creative Capital — the capacity to imagine, create, innovate, express, and bring novel value into existence.
  8. Spiritual Capital — the capacity to experience meaning, purpose, coherence, transcendence, and alignment with values larger than immediate self-interest.
  9. Time Capital — the capacity to direct, structure, protect, allocate, and meaningfully employ one’s finite lifetime.

Other maps of wealth count five, eight, even nine kinds. The 9 Life Capitals are this set: nine capitals named by the capacity each one rests on, read together in one finite life and never summed into one number.

Stewardship Intelligence

Stewardship Intelligence: the capacity to recognise, cultivate, coordinate, and transmit multiple forms of value across time in ways that increase flourishing while preserving the vitality, adaptability, and stewardship capacity of those who follow.

A human capacity, formed in people. Financial expertise can be hired. Stewardship Intelligence cannot.

The same two words also name software for institutional investors — Root has used them since 2024, Diligent since April 2026 — for proxy-voting and engagement data. The Wealth School’s term names a human capacity, not a data product.

Wealth Stewardship

Wealth stewardship is the study and practice of holding wealth well — cultivating and renewing the many forms of wealth, and forming the people who hold them, across time and generations.

Wealth management optimises an asset. Wealth stewardship holds a life.

Existential Portfolio Theory

Existential Portfolio Theory (ExPT), developed by Ryna Mi, is the founding theory of multi-capital wealth stewardship — an account of wealth as nine interdependent capitals held in one finite life, where order matters as much as amount.
