World Oil Chokepoints
The world’s oil dependence is facilitated by a complex delivery
system, which, if disrupted, could dramatically impair the global
economy. Oil supplies are particularly vulnerable at specific geographic
“chokepoints” en route to their final destinations.
Chokepoints are waterways or overland pipelines that transport large
quantities of oil across narrow channels or vulnerable regions.
The consequences of natural disaster, accident, or terrorist attacks
at any of these points would affect our way of life -- from the
financial markets and international trade to airline travel and
gas prices -- for months. Click to enlarge the map and read brief
descriptions of selected maritime and land-based chokepoints that
are imperative to transporting oil globally.
Bosporus Strait: The Bosporus
Straight is a 17 mile long waterway connecting the Black Sea to
the Mediterranean Sea. Each day, more than 3 million barrels are
transported along this route. This strait is one of the world’s
busiest and most difficult to navigate. Over 5,000 oil tankers traverse
the waterway every year, an average of more than 15 per day. Blockage
of this route would severely limit oil shipments to Southern and
Western Europe.
Baku-Tblisi-Ceyhan Pipeline:
The Baku-Tbilisi-Ceyhan oil pipeline stretches 1093 miles across
the countries of Azerbaijan, Georgia, and Turkey and has the capacity
to transport 1 million barrels of oil per day. In addition, Kazakhstan
and Azerbaijan recently signed an agreement to allow for the eventual
export of Kazakh oil through the BTC. The pipeline helps to lessen
OPECs influence by allowing the West direct access to sources of
oil from the Caspian region. Its disruption would reduce this valuable
diversification.
Strait of Hormuz: The Strait
of Hormuz is located between Iran and Oman and connects the Persian
Gulf to the Arabian Sea and Indian Ocean. It is by far the world’s
most important chokepoint; over 17 million barrels of oil per day
(roughly one fourth of the world’s total oil consumption)
travel out of the Persian Gulf through this strait. Closure of the
Strait of Hormuz would dramatically affect the world oil market,
sending oil prices well over $100 per barrel and restricting access
to oil products to only the wealthiest buyers.
Strait of Malacca: The Strait
of Malacca runs between islands in Malaysian and Indonesia and connects
the Indian Ocean with the Pacific Ocean. It is the shortest sea
route between the Middle East and Asian markets and allows shipment
of nearly 80% of the oil to China, Japan, and South Korea. Almost
12 million barrels per day are shipped through this route. Thus,
Asia would feel the initial and most extreme consequences of a disruption
of the Strait of Malacca’s shipping lanes, but the effects
would eventually damage economies worldwide.
Bab el-Mandeb: This strait,
meaning gate of tears in Arabic, connects the Red Sea with the Arabian
Sea, and runs between the Arabian Peninsula and Africa. It is an
important passage from the Indian Ocean to the Suez Canal complex
and the Mediterranean Sea. Three million barrels of oil per day
flow through the strait. Disruption in the waterway would force
oil shipments to Europe around the southern tip of Africa, dramatically
lengthening the shipping timeframe and raising the price of oil.
Suez Canal and Sumed Pipeline:
The Suez Canal and Sumed Pipeline complex is a 101 mile long canal
located in Egypt. It traverses the northeast corner of the country
and links the Red Sea with the Mediterranean Sea. More than 4 million
barrels of oil per day are shipped long this route. Closure of either
the canal or the pipeline would divert oil tankers around Africa
and greatly lengthen transit time.
Panama Canal and Pipeline:
The Panama Canal and Pipeline are located on the isthmus dividing
North and South America. Together, they ship slightly less than
1 million barrels per day.
