INTERNATIONAL TRADE AND BALANCE OF PAYMENTS

International trade involves buying and selling goods between different countries, while domestic trade happens within a single country's borders. The main difference is that international trade faces more barriers like customs duties, exchange rates, and complex documentation. For example, when Nigeria exports crude oil to America, the transaction involves navigating shipping regulations, currency conversion, and tariffs that wouldn't apply if Lagos traders sold goods to Abuja.

Another key difference is that international trade requires more time and higher costs because goods must cross borders. Domestic traders can move products quickly within Nigeria using local transport, but international traders deal with port delays and inspections. International trade also involves greater risk from currency fluctuations and political changes between nations.

Understanding these differences helps explain why prices of imported goods are usually higher than locally produced items.

Countries trade with each other because they cannot produce everything efficiently. The basis of international trade is that some nations have advantages in producing certain goods cheaper or better than others.

Absolute cost advantage means a country can produce a good using fewer resources than another country. For example, Nigeria can grow cocoa more cheaply than Canada because of our climate. Comparative cost advantage is different—it means a country should specialize in what it produces most efficiently relative to other goods it makes.

Think of it this way: even if Nigeria could produce everything cheaper than Ghana, we still benefit by focusing on what we do best and trading for other goods. The terms of trade show the rate at which one country's exports exchange for another's imports—essentially the price of international trade.

International trade simply means buying and selling goods and services between countries. Nigeria, for example, exports crude oil to countries like the USA and imports vehicles and machinery from Japan. When we measure trade, we count the total value of exports (goods leaving) minus imports (goods entering) to get the balance of trade.

Governments use commercial policies like tariffs and quotas to protect local industries. A tariff is a tax on imported goods that makes them more expensive, encouraging people to buy local products instead. Nigeria might place high tariffs on imported rice to protect local farmers from cheap foreign competition.

Commercial policies also aim to earn foreign exchange, create jobs, and prevent dumping where foreign companies sell goods below cost to destroy local competition.

Tariffs are taxes governments place on imported goods to make foreign products more expensive and protect local industries. Nigeria uses tariffs extensively—for instance, the government imposed high import duties on rice to encourage local rice farmers and boost domestic production. There are two main types: ad valorem tariffs charge a percentage of the product's value, while specific tariffs charge a fixed amount per unit.

Direct controls work differently. These include import quotas that limit how many goods can enter the country, and outright import bans on certain items. Nigeria has banned rice importation at different periods to protect its agricultural sector. These instruments help countries control their balance of payments and shield infant industries from stronger foreign competitors.

Understanding the difference matters because tariffs generate government revenue, while direct controls create scarcity and higher prices for consumers.

External trade simply means buying and selling of goods and services between African countries and the rest of the world. When Nigeria exports crude oil to America, that's external trade. When we import vehicles from Japan, that's also external trade.

Most African countries depend heavily on exporting raw materials like cocoa, cotton, and minerals while importing manufactured goods. This creates a problem because raw materials earn less money than finished products. Nigeria exports crude oil worth billions but imports refined petroleum products at higher prices, which weakens our balance of payments.

African trade is also affected by weak infrastructure, high transportation costs, and limited manufacturing capacity. Many African countries trade more with developed nations than with each other, which limits economic growth within the continent.

Money serves as the medium through which countries exchange goods and services across borders. When Nigeria exports crude oil to America, Nigerians cannot accept dollars and use them locally—the dollars must be converted to naira through the foreign exchange market. This conversion process allows Nigerian businesses to receive payment in their own currency and spend it domestically.

Without money, international trade would collapse into complicated barter systems. Money eliminates the problem of finding trading partners whose needs exactly match yours. It also enables countries to store value and settle debts over time. For instance, when Nigeria imports machinery from Germany, payment isn't immediate—money allows credit arrangements between trading partners.

The balance of payments tracks all these monetary transactions between a country and the rest of the world, recording both money inflows and outflows.

Balance of payments is simply a record of all money transactions between a country and the rest of the world over a specific period. Think of it like your personal account book, but for the entire nation. It has two main components: the current account, which includes earnings from exports and payments for imports of goods and services, and the capital account, which tracks investments and loans moving in and out.

Nigeria's oil exports generate huge inflows, but we import many manufactured goods and vehicles, creating what we call a deficit or surplus depending on which side is larger. When a country imports more than it exports—spending more money abroad than it earns—it experiences a balance of payments disequilibrium. This can cause currency problems and affect the economy negatively.

When a country's balance of payments is in deficit, it means more money is leaving than coming in. Nigeria often faces this problem. To fix it, governments use two main tools. Exchange rate policy involves allowing the currency value to change based on market demand. When the naira weakens, Nigerian exports become cheaper for foreigners to buy, so more people purchase them. This helps reduce the deficit. Exchange control is stricter—the government limits how much foreign currency people can buy and sell. During the 2016 oil crisis, Nigeria used exchange controls to manage its naira problems. These controls protect the country's foreign reserves but can create black markets if too restrictive. Both methods aim to balance what Nigeria earns from abroad against what it spends.

When a country's balance of payments shows a deficit—meaning it's spending more foreign money than it's earning—it needs to find ways to cover this gap. Nigeria, for instance, sometimes imports more goods than it exports, creating a deficit. The government can finance this shortfall through several methods: using its foreign exchange reserves (money saved in foreign currency), borrowing from international institutions like the IMF and World Bank, or attracting foreign investment into the country.

Monetary and fiscal policies also play crucial roles. The Central Bank can adjust interest rates to encourage exports, while government can reduce spending to lower import demand. These financing strategies help stabilize the naira and keep the economy functioning smoothly during tough trading periods.

When a country needs money for development but doesn't have enough internally, it can borrow from foreign sources like the World Bank, IMF, or other countries. This is international borrowing, and Nigeria does this regularly to fund projects like road construction, power generation, and infrastructure development. The borrowed money comes with conditions and must be repaid with interest over agreed periods.

International borrowing helps countries finance large projects they cannot afford alone. However, it creates a debt burden that affects the balance of payments. When repaying loans, money flows out of the country, worsening the current account deficit. Nigeria's debt to countries like China and multilateral institutions has increased significantly in recent years, impacting our external reserves and exchange rate stability.

Countries must borrow wisely, investing in productive sectors that generate returns exceeding the loan costs.
