Before any of that matters to a Muslim investor, one question comes first: is Okeanis Eco Tankers stock Halal?
Is Okeanis Eco Tankers Shariah compliant?
No. In the October 2026 screening Okeanis Eco Tankers (ECO) does not pass AAOIFI screening: it fails the interest-bearing debt screen. Industrial businesses like Okeanis Eco Tankers usually pass the activity screen without drama. The harder test is financial: heavy assets mean heavy financing, and AAOIFI Shariah Standard No. 21 tolerates interest bearing debt and investments only below 30% of market capitalisation, ratios that shift with every move in the share price.
Does Okeanis Eco Tankers pass the business activity test?
The activity screen is only part of the picture this month: Okeanis Eco Tankers currently fails the interest-bearing debt screen, so the overall verdict is not compliant regardless of the business itself. The activity itself raises no Shariah objection; the scrutiny belongs to the financing.
Is Okeanis Eco Tankers' income Halal?
Yes, within AAOIFI's tolerance. Okeanis Eco Tankers' income from non-permissible sources stays below 5% of revenue in the October 2026 screening.
Does Okeanis Eco Tankers meet AAOIFI's debt and investment ratio requirements?
Not in full. Interest bearing debt currently exceeds the 30% cap, measured against a market capitalisation of $3.16B (market data as of 1 October 2026), while the other ratio stays within it. One breach is enough to fail the screening; the ratios are reassessed monthly under our Shariah Supervisory Board.
Why do other halal screeners show a different verdict for Okeanis Eco Tankers?
Screeners can disagree without either being wrong. AAOIFI Shariah Standard No. 21, which Tabadulat applies, measures interest bearing debt and investments against market capitalisation with a 30% ceiling. MSCI and FTSE measure them against total assets with a 33% ceiling, and S&P and Dow Jones Islamic use a multi year average of market capitalisation. Data dates differ too, because each provider reads filings and prices on its own schedule. The same company can therefore pass one standard and fail another in the same month. Tabadulat publishes one answer, the AAOIFI result as of October 2026, and re-screens it every month.
