Portfolio Diversification Across Vessel Segments
Summary
Diversification spreads exposure across ship types, sizes, cargoes, employment markets and residual-value drivers.
Why this matters in ship finance
A diversified fleet may stabilise income and collateral, but dependencies can intensify during a global demand shock.
The concept
Segment correlations change with cycle phase, commodity exposure, geographic disruptions and common financing conditions. Vessel counts alone do not indicate economic diversification.
How it is used in practice
Estimate cash-flow and asset-value correlations and concentration limits by vessel type, customer, route and technology; run common-shock stress cases.
Practical issues
Never assume historical low correlation persists in crises; capacity-weighted and exposure-weighted results can differ sharply.
How ShipFinance.ai uses this concept
Maintain portfolio concentration maps and scenario correlations for financing and investment decisions.
Key takeaways
- Diversification must be measured by risk, not ship count.
- Correlation varies over time and in crises.
- Concentrations can arise from common charterers or lenders.
