Causes of changes in globalisation: changes in trade restrictions

Think of trade restrictions as the rules on a game board. When the rules change, the way players (countries) interact also changes. In the real world, these rules are tariffs, quotas, subsidies, and embargoes. Their evolution shapes how globalised the world is.

Trade restrictions are government policies that limit the flow of goods and services between countries. They can be protective (protecting local industries) or regulatory (ensuring safety).

• 📈 Tariffs: Taxes on imported goods.
• 🚫 Quotas: Limits on the quantity of a product that can be imported.
• 🛑 Embargoes: Total bans on trade with a country.
• 💰 Subsidies: Financial support to domestic producers.

1. 🌍 Political shifts: Elections, coups, or new alliances can lead to new trade policies.
2. 💡 Technological advances: Easier logistics reduce costs, prompting lower tariffs.
3. 📊 Economic integration: Joining trade blocs (EU, ASEAN) often means removing barriers.
4. 🛠️ Industrial strategy: Governments may protect emerging sectors with subsidies or quotas.
5. ⚖️ International pressure: WTO rulings or trade disputes can force policy changes.

In 2018, the US imposed a 25% tariff on $34 billion worth of Chinese goods, aiming to protect domestic steel and tech industries. China retaliated with tariffs on US soybeans. The back‑and‑forth changed global supply chains, making companies rethink sourcing and shipping routes.

📚 Analogy: Imagine a school where the principal suddenly bans certain books. Students (companies) must find new books (suppliers) elsewhere, which can be more expensive or harder to get.

Suppose a country imposes a 10% tariff on imported cars. If a car costs $20 000, the tariff is calculated as:

$T = 0.10 \times 20\,000 = 2\,000$

So the final price to the consumer becomes $22 000.

When answering exam questions on globalisation and trade restrictions:

1. 📌 Define the key terms (tariff, quota, embargo, subsidy).
2. 📈 Explain the cause–effect relationship (e.g., how a tariff can protect domestic industry but raise consumer prices).
3. 🗺️ Use real‑world examples (US–China trade war, EU–UK post‑Brexit tariffs).
4. 📐 Show calculations where relevant (tariff amount, price impact).
5. 🧩 Link to globalisation (how changes in restrictions alter supply chains, market access, and economic integration).

Remember: clarity, relevance, and evidence are key.
