Analysts believe Navios Maritime Acquisition — Angeliki Frangou's US-listed tanker arm— may have to sell more vessels to refinance a $670m bond falling due in November.

Fearnley Securities had previously believed increasingly strong tanker supply fundamentals would help the VLCC owner meet the outstanding $600m maturity.

But this has not yet been enough to drive consistently high rates levels due to the current demand crunch, the investment bank said.
