The Weighted Average Cost of Capital (WACC) is the rate at which a company must generate returns to satisfy all of its capital providers. It's the discount rate in dividend discount models and DCF valuations, and it defines whether a management team is creating or destroying shareholder value with its capital allocation decisions.
For hard-asset investors, WACC has an additional dimension: these sectors are cyclical, leveraged, and commodity-price-sensitive. A shipping company's effective cost of capital shifts dramatically between rate supercycles and troughs. Understanding this is essential before applying standard valuation multiples.
The tax shield on debt (1 − Tax Rate) reflects the fact that interest payments are tax-deductible. This makes debt cheaper than equity on an after-tax basis — which is why leveraged capital structures lower WACC, up to the point where financial distress risk starts to dominate.
| Component | Typical value (2026) | Notes |
|---|---|---|
| Risk-Free Rate (Rf) | 4.2% – 4.5% | US 10Y Treasury yield; use local rate for non-USD companies |
| Equity Risk Premium (ERP) | 4.5% – 5.5% | Damodaran ERP estimate for developed markets; higher for EM |
| Beta (β) — Tanker shipping | 1.3 – 1.8 | High cyclicality, spot-rate exposure → elevated beta |
| Beta (β) — Diversified mining | 1.0 – 1.4 | BHP ~1.1, Glencore ~1.3 (commodity exposure + trading) |
| Beta (β) — Gold miners | 0.7 – 1.1 | Gold's safe-haven property lowers correlation to market |
| Beta (β) — Midstream pipelines | 0.6 – 0.9 | Fee-based contracts; lower rate sensitivity post-2020 |
Shipping and mining companies borrow against their physical assets. The nature of debt varies:
| Debt type | Typical spread over SOFR/EURIBOR | Notes |
|---|---|---|
| Ship mortgage (senior secured) | 150 – 275 bps | LTV 60–70% typical; asset value = collateral |
| Project finance (mine) | 200 – 350 bps | Reserve-based; higher for junior miners |
| Investment grade corp bonds (BHP, Rio) | 50 – 120 bps | Low spread reflects diversification and balance sheet strength |
| High-yield (small-cap E&P/shipping) | 400 – 700 bps | Volatile; rises sharply in downturns |
| Revolving credit (midstream) | 100 – 200 bps | Investment grade pipeline companies benefit from low spreads |
Pre-tax cost of debt = Base Rate (SOFR ~5.3% in mid-2026) + Credit Spread. After-tax cost = Pre-tax × (1 − 0.21) for US companies or applicable local rate. For most hard-asset companies, after-tax cost of debt is 4–7%.
| Sector | Typical WACC Range | Key driver |
|---|---|---|
| Product/crude tankers (spot) | 9% – 14% | High equity beta + cyclical cash flows |
| LNG/LPG shipping (chartered) | 7% – 10% | Long-term contracts reduce risk; moderate leverage |
| Diversified mining (BHP, Rio, Glencore) | 7% – 10% | Diversification + strong balance sheets |
| Precious metals miners (Newmont, Barrick) | 6% – 9% | Gold hedging function; lower beta than base metals |
| Upstream E&P (mid-major) | 9% – 12% | Oil price sensitivity + reserve depletion |
| Coal mining | 10% – 16% | ESG premium for cost of equity; limited debt availability |
| Midstream pipelines | 5% – 8% | Contracted cash flows; investment grade; low beta |
The Gordon Growth Model values a dividend-paying stock using:
The cost of equity feeds directly into the denominator. A tanker company with Re = 12% and g = 2% implies a 10% spread — meaning you divide the next dividend by 10% to get intrinsic value. If the same stock yields 11% on current price, it is priced below intrinsic value on this model. See Dividend Discount Model for the full framework.
As a company adds debt to its capital structure, two effects occur simultaneously:
The optimal capital structure minimises WACC. For shipping companies, 50–65% LTV (loan-to-value on fleet) is typically near this optimum. For mining majors with large, long-lived assets, 20–35% net debt/capital is common. For coal under ESG pressure, the optimal leverage is lower because of lender discrimination.
