Best A-Levels for Investment Banking: What the Banks Actually Look For

I'm going to tell you something that most careers advisors won't: choosing the best A-levels for investment banking is less about the specific subjects and more about setting yourself up for the university that gets you in the room. The subjects matter. The university matters more. And the pathway that starts in sixth form is one that most families have never been told about.

I graduated from LSE in 2022 and have been working at a bulge bracket bank in London since. I see applications come through. I know what separates the candidates who make it to interview from those who don't. Let me be direct about what that looks like.

What Maths A-Level Actually Means to Banks

Maths is non-negotiable. Every serious investment banking graduate programme in the UK expects it. Not because investment banking is pure mathematics — it isn't — but because Maths A-Level is the closest thing to a universal signal of analytical rigour. Banks that see a finance applicant without A-Level Maths are already asking why.

The best A-levels for investment banking almost always include Maths as the anchor. For top roles, Further Maths is increasingly valued, particularly if your child is aiming at roles in structuring, quant research or derivatives. But Further Maths is not required for the generalist banking analyst pathway — Maths, a humanity, and a third strong subject is a perfectly competitive combination.

What Economics A-Level Actually Means — and Doesn't

Economics A-Level is not the signal that many families think it is. Banks do not treat it as a proxy for financial knowledge. They recruit from History, English, Politics, Philosophy and virtually every other subject from elite universities. What they look for is analytical thinking, structured communication, and the ability to construct and defend an argument under pressure.

That said, Economics is a reasonable third or fourth A-level subject if your child genuinely enjoys it. The risk is picking it strategically without really engaging with it — then struggling at A-level and underperforming in a subject that was supposed to help.

The Six Target Universities and Why They Matter

This is the part of the conversation that makes some people uncomfortable, but it is the truth of how the industry actually works. Investment banks — particularly the major US firms operating in London — have target university lists. These are the universities they send recruiters to, hold presentations at, and receive the bulk of their applications from.

The core target list is broadly: Oxford, Cambridge, LSE, Imperial, University College London, and Warwick. A second tier of semi-target schools is growing, but the first six account for a disproportionate share of graduate intake at the major banks. This doesn't mean attending a different university closes the door — but it means the door is narrower, and your child will need to be more strategic about everything else.

Getting into one of these six schools requires strong A-Level results across the board. Maths at A or A* is expected. The total profile needs to be convincing, not merely passing.

The Spring Week to Summer Internship to Graduate Scheme Pipeline

Almost no school careers advisor explains this, so let me do so clearly. The pipeline works like this:

1. Spring Week (Year 1 of university): A one-week insight programme, typically in April, where first-year students shadow analysts and attend workshops. Extremely competitive. Banks use these to identify and fast-track promising candidates.
2. Summer Internship (Year 2 of university): A 10-week paid internship, typically converting to a full graduate offer. Most major banks fill the majority of their graduate intake from summer interns. The process begins in October of second year.
3. Graduate Scheme (after university): If you don't have a return offer from your summer internship, you're applying into the open graduate pool — which is significantly harder.

This means that by the time your child is in the second term of their first year at university, the students who are going to get the best graduate jobs are already working their way through the spring week process. The students who arrive at university knowing about this pipeline — and who have the commercial awareness and confidence to navigate it — have a meaningful advantage over those who don't.

Why Starting to Think About Finance in Year 10 or 11 Isn't Too Early

Finance is not medicine. You don't need specific GCSE grades to pursue a banking career. But you do need to be strategic about A-levels (particularly Maths), you need to end up at a target university, and you need to arrive there with some commercial awareness and interview confidence.

Building that takes time. A student who starts thinking seriously about finance in Year 10 — who reads the financial press occasionally, who can talk about what a central bank does, who has a passing familiarity with how companies raise capital — is going to be a much stronger spring week candidate at 19 than one who discovers finance in freshers' week.
