Technology, Globalisation and Fintech: AI, IoT, Blockchain and Trade

Two forces are reshaping every business: technology and globalisation. Technology changes how firms make, sell, pay for and account for things. Globalisation widens the market, and the competition, far beyond a firm’s home town. For accountants, both change the work, the risks and the skills needed.

This topic covers the technologies you must understand (artificial intelligence, the Internet of Things, blockchain, cloud computing and data analytics), fintech in Nigeria, and globalisation with its benefits, risks and effect on Nigerian firms. The Institute of Chartered Accountants of Nigeria (ICAN) Business Environment paper tests all three, often in the same scenario, so you need to explain both the opportunity and the risk.

Key technologies

Artificial intelligence (AI)

Artificial intelligence is the ability of computer systems to perform tasks that normally need human intelligence, such as recognising patterns, understanding language, making predictions and generating text or images. Machine learning, the main approach, lets systems improve by learning from data instead of following fixed rules.

• Uses in business. Chatbots answer customer questions at any hour. Fraud detection spots unusual transactions. Forecasting predicts demand. Automated systems read invoices and post entries. Generative tools draft documents and summaries.
• Benefits. Speed, lower cost for routine work, round-the-clock service and better use of data.
• Risks. Errors and bias in the output, because systems learn from imperfect data. Loss of routine jobs. Privacy and data protection concerns. Over-reliance without human review. Cost and skills needed to run it well.

The Internet of Things (IoT)

The Internet of Things is a network of physical objects with sensors and software that collect data and exchange it over the internet, often with no human involved.

• Examples. Smart electricity meters that report usage. Sensors in a delivery fleet that track location and fuel. Temperature sensors in cold storage for food and vaccines. Sensors on machines that predict a breakdown before it happens.
• Benefits. Real-time information, lower waste, better maintenance, tighter stock control and new services.
• Risks. Poorly secured devices can be hacked and used to attack others. Large volumes of data raise privacy concerns. Devices need power and a reliable network, which is a challenge where either is unstable. Set-up costs are high.

Blockchain

A blockchain is a shared digital ledger. Transactions are grouped into blocks. Each block is linked to the one before it by a cryptographic code, and copies of the ledger are held by many computers in a network. Because every copy must agree, a recorded entry is very hard to change or delete.

• Uses. Cryptocurrencies. Tracing goods through a supply chain. Recording ownership. Smart contracts, which are agreements that run automatically when conditions are met.
• Benefits. A tamper-resistant record, transparency, and fewer intermediaries.
• Risks. Slow processing at scale, high energy use for some designs, unclear regulation and a lack of understanding. Entries that were wrong when made are hard to correct.

Cloud computing, big data and cyber security

• Cloud computing delivers storage, software and processing over the internet, so a firm pays for what it uses instead of buying and running its own servers. It lowers upfront cost and lets staff work from anywhere. It makes the firm dependent on the provider and on internet access.
• Big data and analytics use very large sets of data to find patterns that guide decisions, such as which customers are likely to leave.
• Cyber security protects systems and data. Common threats are phishing (fake messages that trick people into giving away details), malware, ransomware (software that locks files until a ransom is paid) and data breaches.

What technology means for accountants

• Routine bookkeeping and reconciliations are increasingly automated.
• Analytics lets accountants test whole populations of transactions, not just samples.
• More of the value lies in judgement, advice and interpretation.
• Accountants need to understand systems, controls and cyber risk.
• Records held electronically raise questions about security, backup and data protection.

Fintech in Nigeria

Fintech (financial technology) is the use of technology to deliver and improve financial services, such as payments, lending, savings and insurance.

Why fintech matters

• It brings financial services to people and small firms that banks reached poorly, which is called financial inclusion.
• It lowers the cost and time of payments and lending.
• It challenges traditional banks, which respond by investing in their own digital services.

Risks and regulation

The risks include fraud, cyber attacks, loss of customer data, poor customer protection and the failure of small providers. The Central Bank of Nigeria regulates payments and banks. The Securities and Exchange Commission regulates investment services. The Nigeria Data Protection Act 2023 governs how customer data is handled.

More from the syllabus: cloud, blockchain, fintech, statistics and IoT

Cloud computing in detail

Cloud computing means renting computing power and software over the internet instead of owning them, and paying only for what you use, much as you pay for electricity. It has four typical characteristics: elastic capacity that seems limitless, pay-per-use with no long commitment, self-service interfaces, and abstracted or virtualised resources.

Benefits: flexibility, cost cutting, automatic software and hardware upgrades, agility, scalability, elasticity and user convenience. Accounting firms can cut costs, raise productivity and work from anywhere. Challenges: data theft, data privacy, denial of service attacks, wrapping attacks and authentication attacks.

Blockchain in detail

A blockchain is a record of transactions that many computers hold and update together, so no bank or government needs to stand in the middle. Bitcoin was its first real application, solving the problem of double spending without a trusted third party.

The syllabus names five characteristics: records are unmodifiable and unchangeable, the network is decentralised, activity is transparent and anyone can audit it, and settlement is efficient in cost, speed and risk.

In financial accounting, a firm could upload source documents to a blockchain and let smart contracts produce the ledgers and statements automatically, recording the accounting rules permanently. That would reduce measurement errors and earnings management, shorten the gap between events and reporting, make fraud easier to detect and dearer to hide, make accounting choices more comparable, and create thousands of backups.

Challenges are scalability, latency, size and storage, throughput, privacy leakage, regulatory uncertainty and lack of standards.

Fintech applications

Benefits include predictive analytics, transparency, mobile accounting applications and cheaper payment processing.

Statistical modelling

Statistical modelling builds simple mathematical models of a firm’s data to explain patterns and predict what may come next, so managers can decide on evidence. Its applications are:

• Public accounting. Auditors use statistical sampling, for example testing a sample of receivables accounts to judge whether the total is fairly stated.
• Financial analysis. Analysts use price-earnings ratios, dividend yields and market averages to judge whether a share is over- or under-priced.
• Marketing. Checkout scanner data reveals the link between sales and promotions.
• Production. Statistical quality control charts monitor output.
• Economics. Economists forecast the economy from statistical data.

For a business, it helps to locate customers, choose the most effective marketing method and forecast future capital needs.

The Internet of Things in the syllabus

The IoT links everyday objects fitted with sensors and software, so that they gather information, pass it on and respond to it largely on their own. The term was introduced by Kevin Ashton in 1999 in the context of RFID. The focus is machine-to-machine communication.

Applications include smart homes and buildings, healthcare monitoring, manufacturing and predictive maintenance, retail inventory tracking, fleet tracking and smart traffic lights, agriculture sensors, smart meters in utilities, and digital education. The benefits are operational efficiency, data-driven insight, personalised services and new business models.

Globalisation

Globalisation is the growing integration of economies and societies through the movement of goods, services, money, people, technology and ideas across borders.

What drives globalisation

• Technology. The internet and cheap communication link buyers, sellers and workers anywhere.
• Lower trade barriers. Trade agreements and organisations reduce tariffs and quotas.
• Cheaper transport of goods by sea and air.
• Multinational companies that produce and sell in many countries.
• Free movement of capital through banks and financial markets.

Benefits and drawbacks

Globalisation and Nigeria

• Trade blocs. Nigeria belongs to the Economic Community of West African States (ECOWAS). The African Continental Free Trade Area (AfCFTA) aims to create a single market for goods and services across Africa by reducing trade barriers.
• Exports. Nigeria depends heavily on crude oil exports, so world prices affect the economy and the naira.
• Imports and local firms. Imported goods compete with local products, and many firms depend on imported inputs, so the exchange rate affects their costs directly.
• Foreign investment and multinationals operate in telecoms, banking, manufacturing and consumer goods.

How a firm can go global

Worked example: technology and globalisation for a retailer

1. Technology opportunities. An online shop reaches customers across Nigeria and abroad. Payment gateways and transfers speed up payment. Cloud accounting software cuts bookkeeping time. Sales data shows which items sell, so stock can be planned better.
2. Technology risks. Cyber attacks and card fraud. Loss of customer data, which raises data protection duties. Costs of the website and staff training. Dependence on the internet and on payment providers.
3. Globalisation opportunities. Overseas buyers for Nigerian designs. AfCFTA could ease selling to other African countries. A wider choice of fabric suppliers.
4. Globalisation risks. Cheap imported clothing undercuts local prices. A weaker naira raises the cost of imported fabric. Foreign sellers can reach Tolu’s customers online.
5. Recommend. Go online, with strong security and clear data policies. Compete on design, quality and service rather than on price alone. Reduce exchange rate risk by using local fabric where possible or by agreeing prices with suppliers in advance.

Technology and globalisation in more detail

Artificial intelligence: uses and risks

Artificial intelligence is the use of computer systems to do tasks that normally need human intelligence, such as recognising patterns, understanding language and making predictions. Uses: chatbots that answer customers’ questions at any hour; fraud detection that flags unusual transactions; demand forecasting that helps set stock levels; and automation of routine accounting tasks such as invoice matching.

Risks: mistakes or bias in the system’s outputs; loss of jobs in routine roles; use of personal data that raises privacy and data protection duties; over-reliance on outputs that no one checks; and the cost and skill needed to run and secure it.

Selling online: benefits and risks for a retailer

Globalisation: effects and responses

Globalisation is the growing integration of national economies through trade, finance, technology and migration. Opportunities: bigger markets, cheaper inputs, access to technology and ideas, and the ability to sell abroad online. Threats: more competition from foreign firms, including cheap imports; exposure to exchange rate movements; dependence on foreign suppliers; and changes in global prices.

For example, if the firm imports fabric priced at $10 a metre and the exchange rate moves from ₦1,500 to ₦1,800 per dollar, the naira cost per metre rises from ₦15,000 to ₦18,000, a 20% increase. Cheap imported clothing means the firm cannot win on price alone.

How a business should respond

Differentiate on design, quality, fit and customer service. Control costs and buy inputs from several sources, locally where possible. Manage exchange rate risk by agreeing prices in advance, holding some foreign currency or sourcing locally. Use online sales and social media to widen the market, and build a local identity that foreign competitors cannot copy.

Exam focus: artificial intelligence, the Internet of Things and globalisation

Three recent questions came from this topic: artificial intelligence (May 2026, Question 6), globalisation (November 2025, Question 2) and the Internet of Things (November 2025, Question 6). Examiners reported that candidates were weakest on the features of artificial intelligence (AI) and on IoT, where only about 18% scored above average, so learn these lists.

Artificial intelligence: five or more key features

• Learning ability. Systems learn from data and improve without being programmed for every case, using machine learning and deep learning.
• Autonomy. Systems act without human intervention, for example self-driving vehicles.
• Adaptability. Systems adjust to new data and circumstances, for example chatbots that refine their replies.
• Problem-solving and reasoning. Systems apply logic, as expert systems do with predefined rules.
• Perception. Systems interpret images, sounds and text through computer vision and speech recognition.
• Natural language processing. Systems understand and produce human language, for translation, speech recognition and sentiment analysis.
• Predictive analytics. Systems forecast outcomes from data, for example predicting machine failure.
• Automation. Systems perform repetitive tasks, including robotic process automation for data entry and other routine work.

Sectors that use AI

• Healthcare. Diagnosis from medical images, treatment plans and drug discovery.
• Manufacturing. Robots and automation improve output, quality control and efficiency.
• Fashion technology. Design support, inventory management, personalised shopping and trend prediction.
• Education. Personalised learning that adapts to each student’s pace and gives feedback.
• Security and surveillance. Facial recognition and behaviour analysis for real-time threat detection.
• Transportation. Autonomous vehicles, traffic management and predictive maintenance.

Challenges of implementing AI

• Job displacement and unemployment, especially in routine roles.
• Malfunction and risk when systems are badly designed or misused, especially in healthcare or driving.
• Lack of human touch and emotional intelligence, which hurts empathy-based services.
• High cost of hardware, software and skills, which is a barrier for smaller firms.
• Dependency on technology, so failure or compromise can have severe results.
• Limited creativity and originality, because AI recombines existing data.

Exam focus: the Internet of Things (IoT) and globalisation answers

Internet of Things: sectors and uses

• Smart homes and buildings. Energy-saving thermostats, remote lighting and security systems.
• Healthcare. Remote patient monitoring, wearable trackers and real-time diagnostics.
• Manufacturing. Intelligent robotics, predictive maintenance and supply chain automation.
• Retail. Smart shelves, inventory tracking with radio frequency identification (RFID) and personalised in-store experiences.
• Transportation. GPS fleet tracking, smart traffic lights and connected vehicles.

Benefits of IoT to enterprises

• Operational efficiency from better tracking, predictive maintenance and resource use.
• Data-driven insight from continuous data, which improves forecasting and decisions.
• Personalised services, as devices adapt to user behaviour.
• Innovation, including new models such as smart cities and connected healthcare.

Challenges of IoT (learn at least six)

• Reliability. Device or network failure causes data loss, delays and safety risks.
• Performance. It depends on many technologies, and there is no common standard to measure it end to end.
• Interoperability. Devices from different makers use different platforms and protocols, so standards and testing are needed.
• Security and privacy. There is no universal security architecture, so data is open to unauthorised access and breaches.
• Management complexity. Configuring, monitoring and fixing billions of devices is hard.
• Manufacturing and environmental impact. Devices must be cheap to make and sustainable, with reuse and recycling.
• Lack of governance. Fragmented rules and rival identification schemes weaken standardisation and trust across borders.

Globalisation: technology changes, types and aspects

Common mistakes in the exam

• Defining a technology and stopping. Marks are usually for uses, benefits and risks tied to the business in the question.
• Giving only benefits or only risks.
• Mixing up terms: ransomware, phishing and malware are different threats.
• Describing blockchain as a bank database. It is a shared ledger held by many computers.
• Treating globalisation as only good for large firms. Small firms face both new markets and new competition.
• Writing about the world in general with no Nigerian or scenario link.

Quick revision

• AI: machines performing tasks that need human intelligence. Machine learning learns from data. Benefits are speed and cost. Risks are bias, privacy and job loss.
• IoT: connected devices with sensors that share data. Benefits are real-time information and better maintenance. Risks are security and cost.
• Blockchain: a shared ledger of linked blocks that is hard to alter. Used for cryptocurrency, traceability and smart contracts.
• Cloud, big data and cyber security. Know phishing, malware and ransomware.
• Fintech: payments, mobile banking, lending, digital currency. Regulated by the Central Bank of Nigeria, the Securities and Exchange Commission and data protection law.
• Globalisation: drivers, benefits and drawbacks, Nigeria’s trade links including ECOWAS and AfCFTA, and the five ways to go global.
