Russian oil shipments have declined due to drone attacks on Baltic Sea ports.

According to Bloomberg, this is the sharpest drop in supplies since July 2024. Weekly seaborne shipments of Russian oil in the week ending mid-September averaged 3.18 million barrels per day, down almost 950,000 barrels from the previous seven days.
Russian oil shipments by sea have been curtailed by Ukrainian drone attacks on Baltic Sea ports. According to ship tracking data compiled by Bloomberg , 29 tankers loaded more than 22.26 million barrels of oil in just one week. The previous week, 38 vessels loaded approximately 28.79 million barrels of oil.
Weekly seaborne shipments of Russian oil averaged 3.18 million barrels per day in the week ending September 14, down nearly 950,000 barrels from the previous seven days. This represents the sharpest drop in shipments since July of last year.
Russian oil exports from Primorsk fell to approximately 730,000 barrels per day, and from Novorossiysk to 650,000. Shipments from Ust-Luga halved to approximately 313,000 barrels per day. Alexey Belogoryev, Research Director at the Institute of Energy and Finance, comments:
Oil and petroleum product supplies have declined repeatedly; they've been quite volatile over the past three years. But if the decline is solely due to a temporary reduction in port infrastructure capacity, then supply volumes will recover over time. This is a temporary phenomenon, and I think it should be treated as such. In terms of the sustainability of Russian production, there's a safety margin for temporarily reducing production or redirecting volumes to refining. Although refining is also challenging. Recently, Russia has virtually no strategic oil storage facilities of sufficient capacity. The need for them has long been debated. They're expensive, and there's not much space to store oil. All production must be either refining or exported. If the shutdown lasts for weeks, it will lead to a temporary decline in production, but that's not critical. Rather, it will be a reaction to the global market; a moderate price increase is possible against the backdrop of reduced exports from Russia. Our main Russian grade, Urals, is exported through the Baltic ports; it's currently going to India.
— If there are temporary problems, won't India suffer too much?
— Firstly, India has a fairly diversified structure; it can replace supplies, especially if we are talking about a short period of time. There is Iraqi oil, which is close to Russian oil in terms of both cost and characteristics, and there are also reserves at refineries.
According to Bloomberg, on average, over four weeks, export prices for Russian Urals crude from the Baltic and Black Seas fell by 30 cents per barrel, averaging $54.50 per barrel, while the price of Pacific ESPO crude, supplied via the East Siberia-Pacific Ocean pipeline, rose by 20 cents per barrel, to $63.
