Credit Risk & Underwriting
Concentration Risk in Shipping Portfolios
Summary
Concentration risk arises when exposure is clustered by vessel type, charterer, sponsor, fleet age, geography, bank counterparty or financing maturity.
Why this matters in ship finance
Loans that appear diversified by ship number may react similarly to the same freight or trade shock.
The concept
Diversification should be examined along economic dependencies, not just legal borrowers. Cross-guarantees, same ship managers, cargo flows and common debt maturity dates can create hidden correlations.
How it is used in practice
Aggregate exposures and stress earnings and collateral by segment, sponsor and counterparty, including correlated default and recovery outcomes.
Practical issues
Count of vessels is a poor standalone diversification measure. Portfolio risk models must document data gaps and correlations.
How ShipFinance.ai uses this concept
Provide multi-dimensional exposure matrices and portfolio stress tests.
Key takeaways
- Common drivers matter more than ship count
- Hidden sponsor links create concentration
- Correlations may rise under stress
