I get this question more than any other from people just starting to look at tanker stocks: how does this business actually work? You can look up Frontline ($FRO) or DHT Holdings ($DHT) on any stock screener and see a company with a low P/E ratio and a dividend yield that looks almost too good to be true. But before you buy anything, you need to understand exactly how these companies generate revenue, because it is genuinely different from almost every other business you have probably invested in.

This is the plain English explanation.
The Core Business: Renting Out Ships
A tanker company owns ships. Those ships carry crude oil or refined petroleum products from one place to another. The tanker company does not own the oil. It does not trade the oil. It is not an oil company. It is a shipping company, and its job is to move other people’s oil from point A to point B in exchange for a daily fee.
That daily fee is called a day rate or a charter rate. It is the single most important number in the entire business.
When you own a tanker stock, what you really own is a claim on those day rates minus the costs of running the fleet.
What Is a Day Rate and Why Does It Move Around So Much?
A day rate is what a shipper, typically an oil company or a trading firm, pays to charter one vessel for one day. It is set by supply and demand in a global market that moves continuously.
Think of it like a hotel room. When there are more travelers than rooms, prices go up. When rooms are empty, prices fall. Tanker day rates work the same way. When there is more oil to move than there are ships to move it, rates spike. When the world has more tankers than it needs, rates fall and companies start losing money on every voyage.
In a normal, balanced market, a Very Large Crude Carrier, the biggest type of crude tanker, might earn $30,000 to $60,000 per day. In a genuine supply crisis, like the Strait of Hormuz closure we are living through right now, those rates can hit $200,000, $300,000, or even higher. In late 2022 during a sanctions-driven shipping crunch, some VLCCs earned over $100,000 per day for months on end.
For a company running a fleet of 20 VLCCs, the difference between $40,000 day rates and $120,000 day rates is not incremental. It is the difference between breakeven and generating hundreds of millions of dollars in cash per quarter.
Spot Rates vs Time Charter: Two Ways to Get Paid
There are two main ways a tanker company can charter its vessels, and understanding both is important for reading any company’s earnings report.
The first is the spot market. In a spot charter, a vessel is hired for a single voyage at the current market rate. If you charter a VLCC on the spot market today to carry crude from the Arabian Gulf to South Korea, you agree on a rate for that specific voyage right now. If rates go up tomorrow, the next voyage gets the higher rate. If rates crash, the next voyage gets the lower rate. Spot exposure is volatile but captures the full upside when rates run.
The second is a time charter. In a time charter, a vessel is hired for a fixed period, often six months, one year, or even longer, at a fixed daily rate agreed upfront. If you lock in a VLCC on a one-year time charter at $60,000 per day and spot rates subsequently spike to $200,000, you miss the upside. But if rates crash to $20,000, you are still collecting $60,000 every day for the duration of the contract. Time charters provide stability and predictability.
Most tanker companies run a mix of both. When you read an earnings call, you will hear management talk about how much of the fleet is on spot versus fixed charters, and what they are booking forward. This mix tells you a lot about how much of any future rate move will flow through to earnings.
Why Tanker Dividends Are So Different From Normal Dividends
This is where new investors often get confused, and it is worth spending a minute on.
Most companies you are familiar with pay a fixed or gradually growing dividend. Apple pays a certain amount per quarter. Johnson and Johnson raises its dividend a little every year. The payout is predictable and consistent because the underlying earnings are relatively stable.
Tanker companies are completely different. Most of them pay variable dividends that are tied directly to how much cash the company generated that quarter. When day rates are high and the company is printing money, the dividend can be enormous. When rates fall, the dividend gets cut, sometimes to near zero.
This is not a sign that the company is in trouble. It is how the business model is designed to work. Tanker companies are essentially passing through their volatile earnings directly to shareholders rather than holding cash on the balance sheet.
What this means practically: if you buy a tanker stock because you saw a dividend yield of 15%, you need to understand that yield was calculated using earnings from a recent high-rate quarter and may not repeat. The next quarter could pay half as much or nothing at all if rates drop.
What Actually Moves Tanker Stocks
Once you understand the day rate is everything, the question becomes what moves day rates. Three things drive this market more than anything else.
Geopolitics and chokepoints matter enormously. The Strait of Hormuz, the Suez Canal, the Red Sea, and the Bab al-Mandeb are the arteries of global oil trade. When any of them is disrupted, rates spike instantly. The current Hormuz crisis has pushed VLCC day rates to all-time records. This is why tanker stocks and geopolitical risk are permanently linked.
Fleet supply changes slowly. A new VLCC takes roughly two years to build and costs over $100 million. When the order book is light, meaning few new ships are on order, and current vessels are aging out of service, the supply side is tight. Any demand increase hits hard because there are no new ships coming quickly. Right now the tanker fleet is aging and the order book is relatively lean, which is structurally supportive for rates.
Oil demand matters too. More crude moving globally means more ships needed. Less demand, whether from economic slowdowns or energy substitution, reduces the volume of oil moving and softens rates.
The Main Tanker Stocks Worth Knowing
If you are just starting to research this sector, these are the publicly traded names that I follow most closely at TxZen.
Frontline ($FRO) is one of the largest tanker companies in the world by fleet size, with a mix of VLCCs, Suezmax, and LR2 tankers. It is heavily exposed to spot rates and known for paying large variable dividends when rates are high.
DHT Holdings ($DHT) is a pure-play VLCC operator with around 24 vessels. It trades very closely with VLCC spot rates and has historically returned a high percentage of earnings to shareholders.
International Seaways ($INSW) operates in both crude and product tanker markets. It has a reputation for capital discipline and has been more consistent than some peers on shareholder returns.
Hafnia ($HAFN) is one of the largest product tanker operators, focusing on refined fuels rather than crude. Product tankers move gasoline, diesel, and jet fuel, and they benefit from different dynamics than crude tankers, though both react to supply disruptions.
Scorpio Tankers ($STNG) is another large product tanker operator, known for a younger fleet and significant exposure to the MR and LR2 classes.
Nordic American Tankers ($NAT) and Teekay Tankers ($TNK) are smaller operators that tend to attract investors looking for simpler, more direct exposure to the VLCC market.
The Risk You Need to Understand Before Buying
Tanker stocks are not passive, stable investments. They are leveraged bets on day rates, and day rates can fall as fast as they rise. A diplomatic resolution that reopens the Strait of Hormuz overnight could cut VLCC rates by 50% or more in a matter of weeks. Tanker stocks would follow.
These companies also carry significant debt because ships are expensive assets that most operators finance. Rising interest rates increase carrying costs. Vessel accidents, oil spills, and regulatory changes create additional risks.
The upside is real. The downside is real too. Understanding both is the starting point for investing in this sector intelligently.

To see this earnings model in action, DHT Holdings is one of the clearest examples: a pure-play fleet, no diversification games, and a dividend paid from spot earnings. The all-time earnings record post from early 2026 shows what the model produces at scale.
