Hormuz rates power a risky tanker windfall

01 Running thesis

A windfall with a warning label

International Seaways is getting paid very well when oil shipping routes are stressed. In Q1 2026, the company reported record net income of $286 million, helped by higher charter rates tied to the Strait of Hormuz conflict.

The bull case is not only about one hot quarter. Management added an 85% dividend payout ratio, sold 7 older vessels, and is bringing in dual-fuel ready LR1 newbuilds. The company also moved vessel-owning subsidiaries to Bermuda to fit newer global tax rules and keep more strategic flexibility.

The bear case is that this profit spike depends on a dangerous setup. The same conflict that raises rates can also raise fuel, insurance, and safety costs. If the Strait of Hormuz reopens more fully, rates may fall. If the conflict spreads, ships, crews, and schedules face bigger risks.

This makes INSW a strong performer, but not a simple safe-income stock. Investors need to watch both the dividend math and the shipping rate cycle.

May 2026Q1 2026 was exceptionally strong, with record net income of $286 million and a new 85% dividend payout ratio. The same update raised risk because the rate surge is tied to hostilities around the Strait of Hormuz.
Feb 2026The 2025 filing showed Crude Tankers moving to 52% of TCE revenues as Product Carriers weakened. It also confirmed the Bermuda redomiciliation and a lower 2025 income from vessel operations.
Nov 2025The U.S. and China suspended port fees for one year starting November 10, 2025. That delayed a major cost risk, but did not remove it.
Aug 2025The Q2 2025 filing did not add material new operating or risk information. The thesis stayed focused on tanker rates and the pending port-fee issue.
May 2025INSW disclosed a new risk from proposed U.S. fees on China-built or China-linked vessels entering U.S. ports. The company said 10 of its 14 China-built vessels fell within the scope of the proposal.
Feb 2025The complete 2024 10-K removed the prior reporting-transparency concern and shifted focus back to fundamentals. The filing showed a balanced 2024 TCE split, with Product Carriers at 53% and Crude Tankers at 47%.
Nov 2024A second incomplete 10-Q made financial transparency a key governance concern at the time. Later filings resolved that issue, but it remains part of the audit trail.
02 Business model

Ships earn by the day or by the trip

INSW owns and operates tankers that carry crude oil and refined products. Customers include major independent and state-owned oil companies, oil traders, and refinery operators.

The company uses two main ways to earn money. Some vessels take single trips at spot rates, often through commercial pools. Spot means the price changes with the market. Other vessels are fixed for a set time under time charters or bareboat charters, which gives steadier revenue.

This mix gives INSW upside when tanker rates jump. It also exposes the company to sharp drops when demand cools, too many vessels chase cargoes, or geopolitics change shipping lanes.

In 2025, shipping revenues were $843.3 million and TCE revenues were $819.6 million. TCE means time charter equivalent, a shipping measure that compares voyage and time-charter revenue on a daily basis.

03 Product portfolio

Big crude ships, smaller fuel carriers

Cash cow

VLCC crude tankers

VLCCs are very large crude carriers used for long-haul crude oil moves. They benefit when long routes and tight ship supply push daily rates higher.

Steady

Suezmax crude tankers

Suezmax ships carry crude on mid-to-long routes. They add flexibility when customers need vessels smaller than a VLCC.

Steady

Aframax crude tankers

Aframax ships often serve regional crude trades. They can be useful when port limits or shorter routes do not fit bigger tankers.

Cash cow

LR2 product carriers

LR2s move refined fuels such as diesel and jet fuel. This market was weaker in 2025, which hurt Product Carrier revenue.

Growth engine

LR1 product carriers

INSW is adding dual-fuel ready LR1 newbuilds. Two were delivered in early 2026, and the remaining two are expected in Q3 2026.

Steady

MR product carriers

MRs are medium range ships used for refined product trades. They give INSW exposure to many smaller routes and customers.

04 Business segments

Crude took the lead in 2025

Crude Tankers52%modest
Product Carriers48%declining

The segment mix is based on fiscal 2025 TCE revenues. Crude Tankers generated 52% and Product Carriers generated 48%, after weaker average daily rates in Product Carriers.

05 Risk factors

What could break the story

Strait of Hormuz conflict swing

High impact · High odds

Active hostilities in the Arabian Gulf have raised tanker rates, but also raised danger. The company disclosed attacks on merchant vessels and a near-total closure of the Strait of Hormuz as of late April 2026. A calmer region could cut rates, while a worse conflict could disrupt operations.

We watchTrack Hormuz transit status, reported vessel attacks, war-risk insurance rates, and INSW spot-rate updates.

Tanker rate cycle reversal

High impact · Medium odds

Tanker earnings can move fast because spot rates change with cargo demand and vessel supply. INSW benefits when rates jump, but income can fall when more ships compete for fewer cargoes. Income from vessel operations already fell from $455.2 million in 2024 to $345.4 million in 2025 before the Q1 2026 spike.

We watchWatch daily TCE rates by vessel class and management’s booked-rate disclosures each quarter.

Product Carrier weakness lasts

Medium impact · Medium odds

Product Carriers supplied 48% of 2025 TCE revenues, but the segment had lower average daily rates. A recovery is a listed catalyst, which also means it has not yet fully arrived. If refined-fuel shipping stays weak, the crude side must carry more of the profit load.

We watchWatch LR2, LR1, and MR rate trends, plus management comments on Product Carrier demand.

Newbuild execution risk

Medium impact · Low odds

INSW is refreshing the fleet by selling older ships and adding dual-fuel ready LR1s. Two of the four LR1 newbuilds arrived in early 2026, with two more expected in Q3 2026. Delays, cost issues, or poor deployment could weaken the fleet renewal case.

We watchWatch Q3 2026 delivery timing and the first charter rates earned by the new LR1 vessels.

U.S. and China port fees return

Medium impact · Medium odds

The U.S. and China port fee issue is suspended for one year as of November 2025, not solved. INSW had disclosed exposure to China-linked vessels under the proposed U.S. fee framework. If the fees return, certain routes may become more expensive or less attractive.

We watchWatch U.S. and China trade announcements before the November 2026 suspension deadline.
06 Quick answers

In one breath

What does International Seaways do?

International Seaways owns and operates tankers that carry crude oil and refined petroleum products. It earns money by chartering ships for single voyages at market rates or for set periods at fixed rates.

Why did INSW earnings jump in Q1 2026?

Tanker rates rose after disruption around the Strait of Hormuz. That helped INSW produce record Q1 2026 net income of $286 million, but it also tied earnings more closely to a live conflict.

Is INSW mainly a dividend stock?

The new 85% dividend payout ratio makes dividends central to the story. Still, the payout depends on shipping profits, and those profits can swing with tanker rates, fuel costs, insurance, and geopolitics.

What are the biggest things to watch next?

Watch the Strait of Hormuz conflict, Product Carrier rate recovery, the two LR1 deliveries expected in Q3 2026, and U.S.-China talks over suspended port fees. Each can change cash flow and investor sentiment.
