Jaringan tak kasat mata yang menggerakkan perekonomian global – 5 mata rantai lemah

Kabel, jaringan pipa, jalan raya, selat laut, jalur udara dan satelit membentuk jaringan rapuh yang menjadi landasan perekonomian global. Ini adalah jaringan tak terlihat yang sangat penting bagi rantai pasokan global dan kehidupan modern, namun hanya diingat ketika perang seperti yang terjadi di Ukraina atau Israel mengancam salah satu titik strategis tersebut. Studi Deutsche Bank menyoroti lima mata rantai lemah dalam perekonomian global. Artinya, infrastruktur yang tidak dapat digantikan oleh alternatif lain sehingga dapat menghambat rantai pasokan global.

There are some vulnerabilities in the global economy that are more or less known to everyone, such as Taiwan's semiconductor factories, global financial centers and the 0.5% of subway stations in London and Paris that could block the half network.

But there are also the invisible but very important networks, as was shown by the damage done to an undersea gas pipeline and telecommunications cable between Finland and Estonia on October 10, reminiscent of the sabotage of the Nord Stream pipeline a year ago. In 2010, the eruption of a volcano in Iceland "grounded" one second of Europe's air traffic for 8 days, notes Deutsche Bank.

Baik Ukraina maupun Israel terletak dekat dengan titik-titik penting bagi perekonomian global.

1. Kabel dan konduktor

– Kabel data: Up to 99% of the world's digital communications as well as 10 trillion financial transactions. dollars, pass through fiber optic cables located on the sea floor. There are approximately 550 active and planned cables, spanning 1.4 million kilometres. Many are barely thicker than a watering can, explains Deutsche Bank. These cables are vulnerable to espionage and sabotage and to accidental damage.

– Kabel listrik bawah laut: Interkonektor listrik memungkinkan negara-negara membeli tenaga angin atau surya yang lebih murah dari negara-negara tetangga mereka yang memiliki cuaca lebih baik, meningkatkan keamanan pasokan, dan mengelola permintaan dengan lebih baik. Namun, mereka dapat dihancurkan karena sabotase atau kecelakaan.

– Jaringan pipa gas alam: Eropa bergantung pada jaringan pipa untuk sebagian besar pasokan gas alamnya. Pada tahun 2020, mereka mengimpor hampir 40% gas alamnya dari Rusia, dan sejak itu, mereka harus bergantung pada jaringan pipa dari Norwegia dan mengimpor LNG. Seperti yang ditunjukkan oleh ledakan di Nord Stream, jaringan pipa ini rentan terhadap sabotase.

– Saluran pipa minyak: Most of the world's oil pipelines are located in Europe and Asia and start from Russia. A typical oil pipeline is about 50 centimeters in diameter and can carry over 1 million liters (or 6.300 barrels per hour). By comparison, a barrel can carry less than 200 barrels at a time. Pipelines are made of steel and, where possible, are buried in the ground. Like natural gas pipelines, they are vulnerable to damage, earthquakes and sabotage.

2. Jalan raya, rel kereta api, dan sungai

Some railways and roads in far-flung places carry a disproportionately large share of supplies critical to the global economy, with no alternatives. A vast area in the Congo and Zambia, for example, is Africa's largest producer of copper and accounts for two-thirds of the world's cobalt production. But there are only four roads, all bad and congested, to transport these raw materials from the mines to ports in Namibia, South Africa, Mozambique and Tanzania. Something similar is happening with Brazil's soy, which is the world's No. 1 exporter. In the last two years, drought has hit rivers that are vital waterways, showing how vulnerable these transports are.

3. Selat laut

Along with the Cape of Good Hope, there are 8 important "straits" for sea transport. As Deutsche Bank explains, these are the five "keys that unlocked the world" for the British Empire, if the Straits of Dover are removed and the Panama Canal, the Turkish Straits, the Straits of Bab el Madeb and the Straits of Hormuz are added . In oil, for example, more than 60% of supply is transported by sea, with the Straits of Hormuz being the most important point for the market, since a fifth of the world's consumption (and a third of LNG) passes through it. At its narrowest point, the Straits of Hormuz are only 33 kilometers wide.

Selat-selat ini rentan terhadap blokade, tabrakan atau kandasnya kapal, bajak laut, serangan teroris, perang dan kecelakaan seperti tumpahan minyak.

4. landasan udara

Air transport depends on an invisible network of corridors that can be disrupted by weather, wars or unusual events, such as when Spain's airspace was closed last November to allow a Chinese missile to enter Earth's atmosphere. Strikes by air traffic controllers have caused major transport problems in Europe this year, while the biggest post-war air traffic blockade occurred in 2010, when the volcano in Iceland erupted.

5. Satelit

The world is very dependent on the US Global Positioning System (GPS). This uses approximately 30 Earth-orbiting Positioning, Navigation and Timing (PNT) satellites, which send signals to over 4 billion users worldwide. But these signals are weak and prone to interference, and it has been estimated that if GPS is "cut", the cost will exceed $1 billion a day, just for the US.
