For centuries, control of the world's oceans was measured by the size of a navy.
Great powers built battleships, aircraft carriers and submarine fleets because whoever controlled the seas controlled trade.
But a new form of maritime power is emerging.
Today, a small number of missiles, drones or even the threat of attack can influence the movement of goods worth billions of pounds.
The result is a new reality:
The world's narrow sea lanes have become the front line of the global economy.
The recent disruption around the Strait of Hormuz and the Red Sea has demonstrated that you do not necessarily need to defeat a major naval power to create a global economic shock.
You simply need to make shipping companies, insurers and traders believe a route is no longer safe.
Why Narrow Seas Matter
Global trade depends on a handful of strategic waterways.
These are often called chokepoints because there are few realistic alternatives if they become blocked or dangerous.
Some of the most important include:
The Strait of Hormuz, linking the Persian Gulf to the wider oceans.
The Bab el-Mandeb Strait, connecting the Red Sea with the Indian Ocean.
The Suez Canal, linking Europe and Asia.
The Strait of Malacca, vital for trade with East Asia.
The Panama Canal, connecting the Atlantic and Pacific Oceans.
Millions of barrels of oil and enormous quantities of manufactured goods pass through these routes every year.
A problem in one location can quickly become a problem everywhere.
The Red Sea Lesson
The attacks on shipping in and around the Red Sea have changed perceptions.
The lesson is not simply about one conflict.
It is about vulnerability.
Modern shipping depends on confidence.
A container company does not need every ship to be attacked before it changes behaviour.
If the risk becomes too high, insurers increase premiums, crews become reluctant to sail and companies look for safer alternatives.
The result can be enormous disruption without a single ship being permanently lost.
Some vessels have taken much longer routes around Africa rather than using the Suez Canal.
That adds:
More fuel costs.
Longer delivery times.
Higher freight charges.
Greater pressure on supply chains.
Those costs eventually reach businesses and consumers.
The Power of a Small Actor
One of the biggest changes in modern conflict is that expensive military equipment is no longer the only way to influence global events.
Drones and relatively inexpensive missiles have given smaller forces a way to create problems for some of the world's largest economies.
The objective is not necessarily to defeat an opponent militarily.
The objective is to create enough uncertainty that economic behaviour changes.
That is a major shift.
In the past, controlling trade routes required controlling territory.
Today, disrupting confidence can sometimes be enough.
Could Others Copy This Strategy?
This is the question governments around the world are now considering.
If one group can affect global shipping by threatening a narrow waterway, others may look at their own geographical advantages.
The concern is not necessarily that every chokepoint will suddenly become a battlefield.
It is that strategic waterways may become targets for political pressure.
A country or organisation may try to gain influence by threatening:
shipping routes;
energy supplies;
undersea cables;
ports;
or critical infrastructure.
The world economy has become highly efficient—but efficiency has also created vulnerability.
A Return to Economic Geography
For decades, businesses focused mainly on cost.
Where can goods be produced most cheaply?
Where are labour costs lowest?
Where are supply chains most efficient?
But recent events have introduced another question:
How secure is the route between producer and customer?
A factory may be thousands of miles from a conflict zone, yet still be affected if the ships carrying its components must avoid a dangerous area.
This is why companies are now talking more about resilience.
They are considering:
holding larger stocks;
finding alternative suppliers;
shortening supply chains;
avoiding dependence on one transport route.
The cheapest option is not always the safest option.
What Does This Mean for Britain and Scotland?
At first glance, a shipping problem in the Middle East seems far removed from Scotland.
But modern trade does not work that way.
A disruption to shipping can influence:
fuel prices;
food costs;
imported machinery prices;
vehicle parts;
building materials;
business costs.
For rural areas such as Caithness, where transport distances are already significant and many households depend on imported energy supplies, these global pressures can be felt quickly.
The same principle applies to businesses.
A local company may have no connection with the Middle East, yet still face higher costs because a supplier somewhere in its chain is paying more for transport.
The Return of Strategic Thinking
The world spent many years assuming that global shipping routes were secure.
That assumption helped create the modern economy of just-in-time deliveries and highly connected supply chains.
But recent events have shown that geography still matters.
A narrow stretch of water can have an impact far beyond its size.
A drone attack thousands of miles away can influence fuel prices in Scotland.
A shipping delay can affect factory production in Europe.
A regional conflict can become a global economic event.
The Bigger Picture
The future of globalisation may not be determined only by trade agreements and tariffs.
It may also be determined by geography.
The world's narrow seas, canals and shipping lanes are becoming strategic assets once again.
The question facing governments and businesses is no longer simply:
"Can we produce goods cheaply?"
It is increasingly:
"Can we guarantee they will arrive safely?"
The answer will shape energy prices, inflation and economic security for years to come.
The next great economic battles may not be fought over factories or resources.
They may be fought over the narrow passages through which the world's economy must travel.
