Cambridge IGCSE Economics · 0455 syllabus guide
Every unit in the current syllabus, exactly what Cambridge has changed for 2027, and what's simply been renamed or reorganised rather than added or cut — drawn directly from Cambridge's own syllabus documents, not a summary of a summary.
Cambridge IGCSE Economics (0455) is Cambridge International's GCSE-level economics qualification, typically taken by students aged 14–16. A revised syllabus applies to exams from 2027, 2028 and 2029, replacing the outgoing syllabus whose final exams are in 2026. It spans six units — from the basic economic problem to international trade — and is assessed by two externally marked papers.
In one sentence: the 2027 syllabus rewards secure knowledge and clean analysis more, and standalone evaluation less, while weaving sustainability and globalisation through the entire course.
Cambridge publishes the two syllabuses as entirely separate documents — a standalone syllabus for 2026 exams, and a separate one covering 2027, 2028 and 2029. The reliable way to check which one applies is by when a student started covering IGCSE content, not by year-group label, since schools structure the two-year IGCSE differently.
| Student situation | Syllabus | Exam series |
|---|---|---|
| Already sat, or resitting, exams from 2025 or earlier | Outgoing (legacy) | 2023–2025 |
| Currently completing IGCSE Economics content, exam in 2026 | Outgoing — final sitting | 2026 (June / November) |
| Started IGCSE Economics content from August 2025 onwards | New syllabus | 2027 onwards (March series in India; June / November elsewhere) |
If you're not certain which track your child's school has them on, check with the school directly — some move students onto new content earlier or later than this typical pattern.
The new syllabus is examined in the same series as the outgoing one — the exam calendar itself hasn't changed:
| Exam series | Where it's available | Notes |
|---|---|---|
| June series | Worldwide | The main mid-year sitting for most centres |
| November series | Worldwide | The end-of-year sitting |
| March series | India only | Additional early-year sitting for centres in India |
A before-and-after table for every unit. The left column is the outgoing 2026 syllabus, the middle is the new 2027–2029 syllabus, and the right explains the difference. Topics are aligned across the columns, so a dash means the topic exists on only one side. Each unit's summary line tells you how much moved before you open it.

|---|---|---|
| 6.1 International specialisation — specialisation at national level; advantages and disadvantages for consumers, firms and the economy | 6.1 Specialisation and free trade — explicit definitions of specialisation by country and of free trade; advantages and disadvantages | Renamed — free trade moved here from the old globalisation topic, and both terms now need defining |

Both syllabuses use the same two-paper structure — multiple choice, then structured questions — but the timing, marks and internal split of Paper 2 have all moved.
| Outgoing — 2026 | New — 2027, 2028, 2029 | |
|---|---|---|
| Paper 1 — Multiple Choice | 45 min · 30 marks · 30 questions | 1 hour · 40 marks · 40 questions |
| Paper 2 — Structured Questions | 2 h 15 min · 90 marks | 2 hours · 80 marks |
| Paper 2, Section A (compulsory) | 30 marks, unseen source material, part questions (a)–(?) | 20 marks, unseen source material, exactly six parts (a)–(f) |
| Paper 2, Section B (choice) | 3 of 4 questions, 20 marks each (60 marks) | 3 of 4 questions, 20 marks each (60 marks) — unchanged |
| Total marks | 120 | 120 — unchanged |
| Grades available | A* to G | A* to G — unchanged |
The headline change is that Section A — the compulsory data-response question everyone must answer — has shrunk from 30 to 20 marks, while keeping the same unseen-material format. Section B is untouched: still three questions chosen from four, still 20 marks each. Overall Paper 2 has 10 fewer marks and 15 fewer minutes than before.
This is the change with the biggest knock-on effect for how a student should prepare, because it moves where the marks actually sit — not just how many topics there are.
| Assessment objective | Outgoing — 2026 | New — 2027–2029 |
|---|---|---|
| AO1 — Knowledge and understanding | 40% | 43% |
| AO2 — Analysis | 40% | 47% |
| AO3 — Evaluation | 20% | 10% |
| Outgoing — 2026 | New — 2027–2029 | |||
|---|---|---|---|---|
| P1 | P2 | P1 | P2 | |
| AO1 | 50% | 35% | 50% | 40% |
| AO2 | 50% | 35% | 50% | 45% |
| AO3 | 0% | 30% | 0% | 15% |
Key takeaways
Paper 1 is unaffected — it was never an evaluation paper and stays a 50/50 knowledge-and-analysis split. All of the movement happens inside Paper 2, where evaluation's share of the marks has been exactly halved, from 30% to 15%.
It's easy to assume "the weighting shifted" means "the same skills, different marks." Reading the two documents side by side, the descriptions themselves were also trimmed. The outgoing AO3 asked candidates to evaluate information, distinguish analysis from unreasoned statement, recognise uncertain outcomes, and communicate their thinking logically — four distinct expectations. The new AO3 condenses this to evaluating information, data and arguments while recognising that outcomes are uncertain — essentially the same core skill, but with two of the four expectations folded away rather than separately assessed. AO2 saw a similar tightening, from four bullet points to three. AO1's wording barely moved (swapping "show" for "demonstrate"). The pattern is consistent: evaluation was trimmed in both what it's worth and how elaborately it's described; analysis absorbed most of the difference.
Drawn directly from Cambridge's own "changes to this syllabus" appendix. None of these are dramatic alone, but together they trim a meaningful amount of content — concentrated in labour markets, firm growth, and some macroeconomic detail Cambridge judged too niche for the level.
| Unit | What's gone |
|---|---|
| 3 · Workers & firms | Trade unions as a standalone topic — its own definition, its role in the economy, and the advantages/disadvantages of union activity are no longer separately examinable. (Trade unions still appear in a reduced form, folded into wage determination.) |
| 3 · Firms | The causes and forms of firm growth — internal growth (e.g. increased market share) versus external growth (e.g. mergers) as its own topic. |
| 1 · Factors of production | Mobility of capital, enterprise and land. (Labour mobility is retained, folded into the workers unit.) |
| 4 · Government | "The role of government" as a standalone topic (previously covering government's role locally, nationally and internationally). |
| 4 · Fiscal policy | The principles of taxation — the "qualities of a good tax" (equity, certainty, convenience, and so on). |
| 4 · Employment | Changing patterns and level of employment, and the claimant count as a way of measuring unemployment (labour force survey remains). |
| 4 · Inflation | Deflation, beyond a bare definition — its causes, consequences and the policies used to tackle it are no longer taught. |
| 5 · Population | Interpreting population pyramids. (Age and gender distribution of population more broadly is still covered.) |
| 6 · Foreign exchange | Fixed foreign exchange rates, and the distinction between fixed and floating systems. |
| 2 · Market failure | "Factor immobility" as a listed cause of market failure. |
| 2 · Mixed economy | Minimum/maximum price effects specifically in labour and foreign exchange markets (product-market price controls remain), and the general discussion of "how effective is government intervention in overcoming the drawbacks of a market economy." |
| 3 · Households | The explicit comparison of household finances "between different households and over time" (income, interest rates and confidence remain as influences). |
| 4 · Growth & unemployment | Several PPC cross-references tied to recession and growth, and "changes in investment and technology" as an explicitly listed cause of growth. |
Key takeaways
The additions outweigh the removals, and cluster around two things: making the foundational resource-allocation logic explicit at the very start of the course, and threading environmental sustainability and globalisation through units that previously didn't touch them.
Key takeaways
Cambridge's own notes are explicit that beyond the additions and removals above, "the order of some content has changed and wording has been updated to improve clarity," some topics have been "reorganised and reduced in size," and every topic now opens with a short introductory explanation. A few of these are worth knowing about specifically, because they can look like content changes when they're really just relabelling:
One thing that has not changed at all: the command word glossary is identical, word for word, in both syllabuses.
| Command word | What it means |
|---|---|
| Analyse | Examine in detail to show meaning, identifying elements and the relationships between them |
| Calculate | Work out from given facts, figures or information |
| Define | Give a precise meaning |
| Describe | State the points of a topic, or give characteristics and main features |
| Discuss | Write about issues or topics in depth, in a structured way |
| Explain | Set out purposes or reasons, make relationships clear, and support with relevant evidence |
| Give | Produce an answer from a given source, recall or memory |
| Identify | Name, select or recognise |
| State | Express in clear terms |
If a student already knows these nine, nothing new needs to be learned there — the difference under the new syllabus is where each command word tends to show up (fewer high-tariff "Discuss" opportunities, since Section A has fewer marks to spread across its six parts), not what any of them individually demand.
This is the change that's easy to miss from a topic list alone, because it isn't one new unit — it's the same idea reappearing in at least six different places. Environmental sustainability is now a named sixth macroeconomic aim of government, sitting alongside things like full employment and price stability, and it can conflict with economic growth in exactly the way inflation and unemployment traditionally do. It's listed as a reason governments tax, and as a reason they restrict trade. It's a cause of poverty and a factor in why countries develop at different rates. It shows up in the brand-new globalisation content as one of the effects candidates are expected to discuss.
It even shows up in how Cambridge introduces the subject. The outgoing syllabus's "why choose this syllabus" section describes IGCSE Economics in fairly generic terms — economic theory, terminology, numeracy. The new syllabus opens by describing Economics as being about how scarce resources are organised "in a world that faces many challenging economic and environmental issues" — sustainability is baked into the subject's framing before a student even reaches the content pages.
The practical effect: answers that reach for a genuine, current example — a real policy, a real country, a real industry — score better under this syllabus than answers built from textbook stock phrases, because the syllabus itself is written to reward that kind of application.
One table summarising the whole change, for quick reference. Full detail is in the sections above.
| Removed | Added | Renamed / reorganised |
|---|---|---|
| Trade unions (standalone topic) | Globalisation causes & effects (new block) | "Market structure" → "Types of markets" |
| Growth of firms (internal/external) | Reasons for buying/selling foreign currency (new block) | "International specialisation" → "Specialisation and free trade" |
| Principles of taxation ("good tax") | Environmental sustainability as a 6th macro aim | "Globalisation, free trade & protection" → "Globalisation and trade restrictions" |
| Deflation causes/consequences/policy | Scarcity named explicitly; mixed-economy arguments | "Micro vs macro" definitional topic dropped as a heading |
| Fixed exchange rates | Recession causes & consequences; seasonal unemployment | Three basic questions moved to Unit 1 (start of course) |
| Population-pyramid interpretation; claimant count | ATC diagrams for economies of scale; four extra trade-restriction reasons | Trade-union content folded into wage determination |
Assessment: Paper 1 grows to 40 questions / 1 hour; Paper 2 shortens to 80 marks / 2 hours; AO3 evaluation falls from 20% to 10% overall (30%→15% within Paper 2). Total marks stay 120; command words are unchanged.

Worth stating plainly, since the lists above can make this look like a bigger overhaul than it is:
The genuinely new content — the globalisation block and the foreign-exchange reasons block especially — has no legacy past-paper track record behind it, because it simply didn't exist in that form before. That's not a reason to worry; it's a reason to make sure these sections are taught as first-principles economics rather than assumed to be "the same as before, slightly reworded." A student revising only from pre-2027 resources on these specific topics is, in effect, revising a gap that doesn't show up until the exam itself.
The AO3 reduction is the other genuine strategic shift. With evaluation now worth 15% of Paper 2 rather than 30%, and squeezed into a Section A that's lost a third of its marks, every evaluation opportunity that remains carries more relative weight per mark, not less importance. This is exactly where a structured evaluation approach earns its keep — new content areas are where students most often fall back on vague "on the other hand" evaluation, because there's no memorised paragraph to reach for. It's a large part of why we teach evaluation at KS Academia Prep as an explicit, repeatable structure — the KSAP Evaluation Method — rather than leaving it as "discuss both sides" and hoping it clicks under exam pressure.
Studying the 2027 syllabus? KS Academia Prep teaches both the outgoing and revised Cambridge 0455 specifications, with lesson materials and Study Supervision built around the current assessment objectives.
See IGCSE Economics tuitionBoth, in different places. Some topics have simply been renamed or moved — wage determination absorbing most of the old trade-union content, for instance, or "market structure" becoming "types of markets." But the globalisation and foreign-exchange sections are genuinely new content blocks, not reshuffled versions of what came before, and topics like firm growth and the principles of taxation have been removed outright rather than moved anywhere.
As a standalone topic, yes. The definition of a trade union, its role in the economy, and the advantages/disadvantages of union activity are no longer separately examinable. Trade unions still appear in a narrower form, as one influence within wage determination.
Not as an explicit, named topic — that definitional section has been dropped from the content overview. The distinction still shapes the syllabus's structure (Units 2 and 3 are microeconomic, Unit 4 is macroeconomic), but it's no longer something a student is required to define and explain up front.
No. The same nine command words — Analyse, Calculate, Define, Describe, Discuss, Explain, Give, Identify, State — appear with identical definitions in both the 2026 and 2027–2029 syllabuses.
Yes. The diagram-based core of the syllabus is unchanged. What's shifted is the balance of marks around it: more weight on knowledge and analysis, less on evaluation, which affects how a response should be structured more than which diagrams are examinable.
No. Cambridge IGCSE Economics (0455), Cambridge IGCSE (9–1) Economics (0987) and Cambridge O Level Economics (2281) are treated as the same subject at the same level, and a candidate can't be entered for more than one of them in the same series.
Not harder in the sense of covering more difficult theory — the conceptual core is the same. It's arguably more demanding on secure knowledge and clean analysis, since AO1 and AO2 now carry more marks, and it rewards real-world application (sustainability, globalisation) over memorised phrasing. The upside for many students: with evaluation weighted lower, there's slightly less riding on the single hardest skill. "Different emphasis" is a fairer description than "harder."
No. Most of what they've learned still applies — the core theory and the two-paper format are unchanged. The practical risks are narrow and manageable: making sure the genuinely new topics (the globalisation and foreign-exchange blocks) are actually taught, not skipped as "similar to before," and adjusting exam technique to the new paper timings and mark split. Both are straightforward to address with up-to-date materials.
Mostly, with care. Notes on the unchanged core — demand and supply, elasticity, market failure, the PPC, inflation, unemployment — transfer directly. What needs updating: remove the deleted topics (trade unions as a topic, firm growth, principles of taxation, deflation detail, fixed exchange rates) so you're not over-revising, and add the new globalisation and foreign-exchange content, which older notes won't cover. A textbook endorsed for first examination from 2027 is the safest base.
Three shifts. First, treat Paper 1 as a trainable skill, not "the easy paper" — it's now 40 questions in an hour and carries more of the analysis weighting. Second, don't over-invest in long evaluation set-pieces; with AO3 lower, secure knowledge and tight analytical chains earn more marks per minute. Third, build a bank of real, current examples for the sustainability and globalisation content, since that application is exactly what the revised syllabus rewards.
It's widely seen as one of the more accessible IGCSE subjects to start, because it assumes no prior economics and is built on intuitive ideas. The difficulty sits less in the concepts and more in exam technique — using command words correctly, labelling diagrams to the mark scheme, and structuring evaluation. That gap between "understanding it" and "scoring on it" is where most lost marks actually come from.
Cambridge treats IGCSE Economics (0455), IGCSE 9–1 Economics (0987) and O Level Economics (2281) as the same subject at the same level, and they were all revised together for 2027 with the same content changes. Differences between them are mostly in grading scale and availability by region rather than in difficulty of content.
Six units: (1) the basic economic problem, (2) the allocation of resources, (3) microeconomic decision-makers, (4) government and the macroeconomy, (5) economic development, and (6) international trade and globalisation. Each divides into sub-topics — the full map is in the "unit by unit" section above.
Calculators are permitted in both Paper 1 and Paper 2. Cambridge's syllabus doesn't mandate a specific model, but schools usually have their own approved-calculator policy, so it's worth checking with the school which model your child should bring.
Yes. Cambridge states that private candidates can enter for this syllabus; entries are made through a registered exam centre rather than directly. The Cambridge Guide to Making Entries has the detail, and a centre's exams officer can advise on the process.
There's no fixed number. Cambridge sets grade boundaries fresh for each exam series to keep standards consistent across papers of slightly varying difficulty, so the mark needed for an A* moves from session to session and isn't published in advance. Past-series boundaries are released after results and can be used as a rough guide, but never as a guaranteed threshold.
Many of Singapore's international schools following the Cambridge pathway offer IGCSE Economics, though provision varies school to school and some use a different exam board or offer the IB route instead. The most reliable way to confirm which specification (Cambridge 0455 versus another board) your child's school uses is the school's subject handbook or exams officer.
Cambridge International publishes both directly: the outgoing 2026 syllabus and the new 2027–2029 syllabus, including a full "changes to this syllabus" appendix in the new document from page 34 onwards.
We teach both the outgoing and new IGCSE Economics content at KS Academia Prep, and can tell you within one message which syllabus your child's exam falls under. Lessons run in English, Simplified Chinese and Korean at Far East Shopping Centre, Orchard Road.
Every syllabus detail in this guide is drawn directly from Cambridge International's official 0455 syllabus for 2026 (Version 2, published December 2025) and 0455 syllabus for 2027–2029 (Version 1), including the official "Changes to this syllabus" appendix. Last checked 21 July 2026 — re-verify against Cambridge's site before relying on this for a specific exam series, as syllabus documents are occasionally amended.
