On January 1, 2020 the International Maritime Organization (IMO) implemented new fuel standards for oil-powered vessels, except those equipped with exhaust scrubbers to remove pollutants. In the absence of a scrubber, the IMO 2020 rule stipulates that ships' bunkers contain less than 0.5% sulfur. Using a scrubber allows the vessel to burn cheaper high-sulfur fuel. Last March, a shipowner’s estimated $2.5 million scrubber investment for a 2-MMbbl Very Large Crude Carrier (VLCC) would take just over three years to recover, based on average fuel prices during the first quarter of 2019. This year, barely a month after the new regulation came into force, the payback period has shortened dramatically, to less than a year, though the coronavirus’s effect on shipping demand and fuel prices, among other factors, could again put payout timing at risk. Today, we look at changing price spreads between high-sulfur and low-sulfur bunker and the scrubber payback economics that suggest a rosier outlook for vessel owners who invested in scrubber installations, at least for now.
