Spot-market days measure fleet days employed in the shipping spot market rather than under longer-duration time-charter arrangements.

The metric helps investors understand how much of a fleet's near-term earnings are exposed to prevailing freight rates.

Why spot days matter

A larger share of spot-market days generally means reported earnings can respond more quickly to changes in freight rates.

That can create:

  • more upside when spot rates rise;
  • more downside when spot rates fall;
  • greater quarter-to-quarter earnings volatility; and
  • less contracted revenue visibility.

A lower spot share can indicate more time-charter coverage, but the economics still depend on the contracted charter rates.

Example

Suppose a fleet has 6,000 calendar employment days:

text
1Spot-market days = 2,100
2Time-charter days = 3,900
3
4Spot share = 2,100 ÷ 6,000
5           = 35%

The issuer's exact denominator may differ, so preserve its methodology.

Spot days versus TCE

Time Charter Equivalent Rate measures daily shipping earnings after specified voyage adjustments.

Spot-market days measure the amount of fleet time exposed to spot employment.

A company can therefore have more spot days without having a higher TCE rate if market pricing weakens.

Investor interpretation

Use spot-market days with:

  • time-charter days;
  • vessel class;
  • current freight rates;
  • charter duration;
  • fleet utilization; and
  • voyage expense.

The same spot exposure can produce very different earnings outcomes across tanker, drybulk, container, and other shipping markets.

Filing example

Imperial Petroleum reports spot-market days and time-charter days as separate fleet-employment measures. For 2025 it disclosed 1,979 spot-market days and 3,812 time-charter days, a materially different mix from the prior year.

Spot-market days are an employment-mix measure, not a freight-rate measure. They show how much fleet time is exposed to current market pricing.

Part of the Shipping Operating Model

Connect fleet scale and age, owned and chartered capacity, availability, utilization, market exposure, daily earnings, and vessel costs to understand shipping operating economics.

How the model fits together
  • Fleet capacity and utilization: Ownership days measure time-weighted fleet size, available days remove specified scheduled off-hire, operating days remove additional off-hire, and fleet utilization relates operating days to the available-day base.
  • Daily revenue and vessel cost: Time-charter-equivalent rate converts shipping earnings to a per-day revenue measure, while daily vessel operating expense converts recurring vessel-level costs to a per-day basis so investors can compare unit economics across changes in fleet size and utilization.
  • Fleet scale, availability, and market exposure: Fleet deadweight tonnage and average fleet age describe physical capacity and fleet quality, chartered-in and earnings-capacity days extend the controlled fleet beyond owned vessels, off-hire days identify lost earning time, and spot-market days show how much employed capacity remains exposed to current freight rates.
