What banking is, how it works, what it pays, and how to build a career in it across four countries.
A full knowledge base written from experience, not a textbook.
Five sections. Real data. Zero jargon.
Most people interact with one part of banking their whole lives and never see the full picture. I've worked across four of these divisions over 10 years, in Nigeria, London, and Toronto. Here's what each one actually does, from the inside.
Gani's perspective: Access Bank Nigeria → JPMorgan Chase London → a global bank in Toronto. 10 years. This is what I actually saw.
Retail banking is what most people think of when they hear "the bank", branches, ATMs, current accounts, savings, and basic loans. It's the front door of the financial system and the division where most banking careers begin, including mine at Access Bank Plc in Lagos.
It's operationally intensive, customer-facing, and teaches you the fundamentals of how money moves at the ground level. Every transaction, every product, every complaint, it all passes through retail.
Consumer banking goes deeper than retail, it's about individual financial products at scale. Mortgages, personal loans, credit cards, wealth products, and the risk models, data analytics and behavioural insights behind them.
This is where banks make significant revenue from individuals, and where data science meets finance. If you understand credit risk, customer segmentation and lifetime value, you understand consumer banking.
Corporate banking serves businesses, from small companies to large multinationals. The relationships happen at C-suite and board level, deal sizes run into the tens of millions, and the products are significantly more complex than anything in retail.
Cash management, trade finance, structured lending, FX hedging, corporate banking underpins how companies operate globally. Less visible than investment banking, but equally well-paid and arguably more stable.
This is where I spent most of my career, at JPMorgan Chase in London, across Regulatory Controls and Asset Servicing. Investment banking is the engine room of capital markets: M&A, IPOs, debt issuance, derivatives, and the complex infrastructure that makes global finance function.
It's demanding, technically sophisticated, and the highest-paying area of banking. It's also where the most interesting problems live, and where understanding the full system pays dividends.
Private banking is the most exclusive tier in all of finance. Clients typically hold $1M+ in investable assets, and the service they receive is entirely bespoke, from personalised investment strategies to estate planning, philanthropy and succession planning.
The relationship is everything. Private bankers manage a small number of very high-value clients, and discretion, trust and deep financial knowledge are non-negotiable. It's a long career path, but an extremely rewarding one.
What each role actually involves, not the job description version, the real version.
Real base salaries at Tier 1 banks, UK, Canada, and Nigeria. Bonuses can add 20 to 100% on top at senior levels. These figures are based on market data and industry experience across multiple Tier 1 institutions.
Bonuses vary significantly by bank, year, and performance. Generally higher at senior levels and in investment banking divisions. The figures above are base salaries only.
UK & Canada: pension contributions, health cover, gym, share schemes, and often subsidised meals. Total comp significantly exceeds base.
Most offers have some flexibility, especially for experienced hires. It's always worth having the conversation, the worst they can say is no.
Nobody prepares you for the intersection of career ambition and immigration bureaucracy. I navigated both, twice. Here's what I learned, lived, and wish someone had told me earlier.
Important disclaimer: I am not an immigration lawyer, immigration consultant, or licensed immigration adviser. Nothing on this page is legal or immigration advice. Everything here is based purely on my own personal experience navigating these systems. Immigration rules change regularly and vary by individual circumstance, so always verify current requirements with a regulated immigration professional before making any decisions.
The UK Skilled Worker visa (formerly Tier 2) is the main route for international professionals entering the UK job market. To get it, you need a job offer from a licensed sponsor, which means your employer must be approved by the Home Office to hire international talent.
In banking, large institutions like JPMorgan, Goldman Sachs, HSBC and Barclays are all licensed sponsors. Smaller firms may not be, this is something to check before accepting an offer.
After 5 continuous years on a Skilled Worker visa, you become eligible for Indefinite Leave to Remain (ILR), effectively permanent residency in the UK. This removes the employer tie and gives you the freedom to change jobs, take a career break, or start a business without visa consequences.
ILR is a significant milestone. Many people in banking reach it and stay, others, like me, use the stability it offers as a launchpad to explore other opportunities abroad.
Canada's work permit system is distinct from the UK's. Most employer-specific work permits require a Labour Market Impact Assessment (LMIA), a document proving the employer couldn't find a suitable Canadian citizen or PR for the role. Some categories are LMIA-exempt, including intra-company transfers and certain trade agreement roles.
For banking professionals moving to Canada, intra-company transfer pathways (if your employer has a Canadian office) or Express Entry can be strong routes in, depending on your situation.
Canada's Express Entry system is one of the most transparent immigration pathways in the world, it's points-based, and your score (CRS score) determines your invite to apply for PR. Factors include age, education, language scores, and Canadian work experience.
As a banking professional with an MSc and English as a first language, you're generally well-positioned for Express Entry. Provincial Nominee Programs (PNPs) can also accelerate the process, Ontario, Alberta and BC all have strong banking sectors.
"Managing a visa while changing careers and countries simultaneously is genuinely one of the hardest things to do, not because it's impossible, but because nobody documents the combination. You're figuring out immigration law, employer sponsorship, and career strategy all at once. Banking Decoded will have a full guide to this, with the real details, not the sanitised version."
