The Baltic Dry Index (BDI) is the most widely followed gauge of dry bulk shipping demand in the world. Published daily by the Baltic Exchange in London, it aggregates freight rates across Capesize, Panamax, and Supramax vessels on 20+ major global trade routes.
For investors in shipping stocks — Star Bulk, Golden Ocean, Genco, Eagle Bulk, Diana Shipping — the BDI is the closest thing to a real-time earnings indicator before quarterly reports arrive.
The BDI is not a traded instrument. It is a weighted average of daily freight rates (in $/day) across three vessel classes:
| Component | Vessel Size | Main Cargoes | Weight |
|---|---|---|---|
| Capesize Index (BCI) | 100,000+ DWT | Iron ore, coal | ~40% |
| Panamax Index (BPI) | 60,000–80,000 DWT | Coal, grain, fertilizers | ~30% |
| Supramax Index (BSI) | 50,000–60,000 DWT | Grain, steel, minerals | ~30% |
The daily calculation surveys actual freight bookings from shipbrokers in multiple countries. This makes the BDI a genuine market signal — not an estimate — reflecting real supply and demand for dry bulk tonnage right now.
All-time high: 11,793 (May 2008, pre-financial crisis)
All-time low: 290 (February 2016, fleet oversupply)
2021-2022 spike: 3,500–5,600 (post-COVID demand surge + supply bottlenecks)
2023-2024 average: 1,200–1,800 (normalization, Panama Canal drought)
2026 YTD range: 1,100–2,400 (Chinese steel demand volatile; Red Sea rerouting supporting Capesize)
A BDI above 2,000 is generally profitable for most dry bulk operators. A BDI below 1,000 means many ships are losing money on voyage costs.
Dry bulk companies pay dividends directly out of charter revenue. When BDI is high, operators earn $30,000–$60,000/day per Capesize vessel. At $20,000/day, they barely cover operating costs. The connection to dividends is almost mechanical:
This is why stocks like Star Bulk (SBLK) and Golden Ocean (GOGL) show high volatility: they pass the majority of their earnings directly back to shareholders as variable dividends. When BDI doubles, their dividends can triple. When BDI halves, dividends may disappear entirely.
The BDI covers dry bulk only — coal, iron ore, grain. It does not cover tankers (crude oil, LPG, LNG, product tankers). Those markets have their own indices:
Marco's portfolio focuses heavily on tankers (CMB.Tech, Dorian LPG, TORM) rather than dry bulk — so for his positions, the TCE Rate and VLGC spot rates are more directly relevant than the BDI.
The BDI has historically been watched as a macro signal — dry bulk ships move the raw materials of economic growth. A rising BDI can suggest accelerating Chinese steel production, recovering global trade, or infrastructure expansion. A falling BDI may signal slowing industrial demand.
Caution: The predictive value has weakened since 2010 as the global fleet expanded significantly. Fleet supply now matters as much as demand. A rising BDI in 2026 may signal fewer new vessels delivered (supply constrained), not necessarily stronger demand.
Key BDI drivers in 2026:
For Marco's portfolio and the broader hard-asset investing framework: BDI monitoring is secondary to tanker markets — but a sustained BDI above 1,800 tends to correlate with positive risk appetite for shipping stocks broadly.
