Saudi Arabia draws down oil stocks to maintain supply after attack

LONDON (Reuters) - Saudi Arabia will try to maintain oil supplies to its major customers by drawing down crude stored at tank farms in the kingdom and in its global network while repairing and replacing installations damaged in the recent attacks.

Saudi Arabia reported domestic crude stocks of 180 million barrels at the end of July, government data supplied to the Joint Organisations Data Initiative showed.

Saudi Aramco, the national oil company, also maintains a few tens of millions of barrels of forward storage near its customers in leased tank farms in the Netherlands, Japan and Egypt.

Aramco holds crude for strategic reasons to cover emergencies, and for operational purposes to ensure an uninterrupted flow of the right grades of oil to domestic refineries and overseas customers.

Domestic stocks were relatively low at the end of July, having fallen by 50 million barrels (22%) since July 2018 and by 150 million barrels (45%) from their post-slump swollen peak in October 2015.

The sustained drawdown over almost four years has left domestic stocks at their lowest level since 2007, numbers from JODI showed.


At the end of July, stocks were sufficient to cover 18 days’ worth of exports, domestic refinery requirements and direct crude burning in the kingdom’s power stations.

Forward cover is down from a recent peak of almost 33 days in October 2015 and is close to the lowest level for over a decade.

Stocks should enable the kingdom to maintain supplies to customers in the short term until installations at Abqaiq and Khurais can be repaired/bypassed, or alternative production and processing capacity can be brought online.

Saudi Arabia’s energy minister said on Tuesday the kingdom had already managed to recover supply to customers to its pre-attack level — by implication using stored crude.

The minister also predicted oil production would be fully restored to its previous level by the end of the month (“Saudi Arabia to restore oil output fully by end of September”, Reuters, Sept. 17).

But stocks can only cover a limited and fairly short loss of production, which underlines the importance of repairing and replacing Abqaiq and Khurais as quickly as possible.

The kingdom may also reduce its own refinery processing to prioritise crude for export and make limited crude stocks go further.

Saudi Aramco’s trading arm has reportedly been trying to buy diesel to offset reduced output from domestic refineries (“Saudi Aramco’s trading arm wants refined products after attacks”, Reuters, Sept. 17).

Saudi Arabia’s crude stocks are performing their intended role to act as a cushion against an unexpected production loss but they buy only a relatively short amount of time to get production back to pre-attack levels.

Trading and investing can be a challenging and potentially profitable opportunity for investors. However, before deciding to participate in the market, you should carefully consider your investment objectives, level of experience, and risk appetite. Most importantly, do not invest money you cannot afford to lose.

There is considerable exposure to risk in any investment transaction. Any transaction involving securities involves risks including, but not limited to, the potential for changing political and/or economic conditions that may substantially affect the price or liquidity of a currency. Investments in speculation may also be susceptible to sharp rises and falls as the relevant market values fluctuate. The leveraged possibility of trading means that any market movement will have an equally proportional effect on your deposited funds. This may work against you as well as for you. Not only may investors get back less than they invested, but in the case of higher risk strategies, investors may lose the entirety of their investment. It is for this reason that when speculating in markets it is advisable to use only risk capital.
