When Brett King printed Bank 2.0 in 2010, loads of financial institution boardrooms dismissed as fiction his argument that banking would turn into one thing you do somewhat than someplace you go. Sixteen years and several other books later, that decision has largely performed out as he mentioned it will. His eighth banking ebook, Bank 5.0: The Rise of the Agentic Bank, makes a far larger one: the following buyer of the financial institution is probably not a human in any respect.
The Fintech Times has learn an advance assessment copy forward of the ebook’s world launch on 19 November 2026 on the Singapore FinTech Festival, the place King delivers the Banking 5.0 keynote earlier than a ebook signing along with his contributing authors. Wiley publishes the worldwide English version and Marshall Cavendish Business the Asia version.
The argument in a single line
King states his thesis early and returns to it usually: “By the middle of this century, half of all economic activity will be initiated, negotiated and executed by machines.” If he’s proper, the AI brokers doing that work will want monetary infrastructure constructed round them. Identity, settlement, credit score decisioning and compliance had been all designed for a human who indicators a kind, goes to sleep and waits for a reply. The again cowl places it plainly: “Those agents will need banks engineered for them. Not for us.”
Readers of the sequence will recognise the construction. Bank 2.0 was about self-service, Bank 3.0 about cellular and Bank 4.0 about banking in all places. In the closing chapter King describes Bank 5.0 as one thing bigger: “the transition from financial intermediation to economic orchestration.”
Part I: why King thinks that is inevitable
The opening 5 chapters make the case that AI is, in King’s phrases, “not overhyped; if anything, it is under-hyped”. He strikes shortly from the historical past of automata to China’s darkish factories, the labour market debate and the tempo of frontier mannequin releases, and argues that banks don’t want to attend for synthetic normal intelligence to be disrupted. Today’s agentic instruments are already sufficient to automate most banking workflows.
The banking expertise chapter strips merchandise again to the three utilities beneath them: storing cash, transferring cash and accessing credit score. Everything else, King argues, is a historic wrapper that generative interfaces will dissolve. “In agentic banking, the interface is the agent.”
The chapter on how fintechs “ate the banks’ lunch” is King at his most combative. He walks by means of every incumbent dismissal of neobanks over the previous decade and makes use of the expansion of Nubank, Revolut, WeBank and Barq to indicate how every one aged. On Barq, the Saudi neobank whose board he sits on, he discloses his curiosity. Anyone nonetheless satisfied that being a strong conventional financial institution is sufficient, he warns, “will probably choke on your iced matcha latte.”
The part closes with a line that may divide bankers and regulators: “Humans will only slow down the operation of the 21st century banking industry”, King writes. A number of pages later he units out the governance mannequin the remainder of the ebook relies on: “humans govern objectives, boundaries and accountability; AI executes within constraints.”
A ebook of many voices
Bank 5.0 just isn’t a solo effort. Nine contributing authors write or co-write chapters, and several other of them are among the many strongest within the ebook.
Dr Efi Pylarinou opens Part II by calling agentic commerce “the third rupture”, after the Silk Road and e-commerce. Her most helpful statement is a blind spot she finds throughout the trade: “the banking industry is building infrastructure for agents as employees or co-workers. Almost nobody is building infrastructure for agents as customers.” Her account of six agent cost protocols arriving in 18 months, from Stripe and OpenAI to Visa, Mastercard, Klarna and PayPal, is a useful map of a requirements race that modifications month to month.
King’s personal chapters on the orchestration layer and on knowledge give the ebook its central technical declare: “a bank will be able to compete without a classic core banking system, but not without a data lake and foundation model strategy.” His shortlist of the primary agent varieties (engagement, transaction, decision-making and operational) gives a sensible vocabulary for any financial institution drawing up an structure.
André Vellozo’s chapter on knowledge financial savings is essentially the most authentic within the ebook. Today’s agent cost stack solely seems to be outward, treating the human as a supply of funds and authority. Vellozo turns that spherical: the identification binding that makes an agent accountable can even make its proprietor a beneficiary. “A binding strong enough to assign blame is, by construction, strong enough to assign benefit.” Agent output settles into an owner-side “dWallet”, which he calls “the largest unclaimed deposit base in the history of banking.”
David G.W. Birch then makes the case for Know Your Agent along with his regular wit and directness: “Without KYA, we can’t have nice things.” His conclusion that banks ought to present the belief infrastructure for agentic commerce, as a result of “AI is not by itself a defense against AI, but real cryptography is”, is the clearest strategic opening for incumbents within the ebook.
The tech stack, from Huawei’s vantage level
Part III is written by Jason Cao, CEO of Huawei Digital Finance, and edited by King. It is essentially the most engineering-led part. It covers a resilience commonplace Cao calls the “Four Zeros” (zero downtime, zero wait, zero belief and nil contact), cloud-native cores and a real-time knowledge layer. Cao’s distinction between the AI a buyer sees and the potential the financial institution builds behind it’s sharp: “Customer AI is the expression; Bank AI is the capability. One cannot outperform the other.” So is his argument that behavioural knowledge, not the mannequin, turns into the moat: “Google trains their engines on search. TikTok trains theirs on recommendations. Amazon trains on shopping behavior. What will banks train on?”
Readers ought to know that it is a vendor’s perspective. The headline metrics should not independently sourced, and the Chinese core migration case research don’t identify the banks concerned.
The half-second market
Part IV is the place the ebook is most vivid. J.Okay. Khalil, previously Division President at Mastercard, writes three chapters that flip the agentic financial institution from structure into lived expertise. Products give approach to intent: “A mortgage is not the desire. A home is.”
His “junk drawer” passage is an effective one. It inventories the worth most of us depart scattered throughout expiring air miles, pay as you go playing cards and forgotten wallets, and units it in opposition to loyalty economics: “Breakage was the silent profit line.” Once brokers route spending to wherever worth is biggest, that line disappears. The identical goes for pricing. The half-second between a buyer’s sure and the affirmation display screen turns into a reside negotiation between buyer, service provider, financial institution, lender and insurer brokers. His message to incumbents is reassuring and pointed without delay: “agents do not punish margin. They punish opacity.”
Khalil doesn’t duck the dangers. Ambient, in-context credit score, he warns, “done poorly”, turns into “the most efficient predatory lending machine ever built”. On accountability he’s blunt: “A bank cannot say, ‘The AI did it’.”
King’s chapter on monetary inclusion raises what he calls the inclusion paradox: “AI may give every citizen access to world-class financial services while simultaneously reducing the number of citizens earning sufficient income to use them.” Jonathan Holman, CEO of Nebras Open Finance, the UAE’s nationwide open finance operator, closes the part with a measured have a look at what brokers constructed on open banking rails might imply for the financial institution’s possession of the client: “The teller fronting all financial services may return, but it might not be employed by the bank at all.”
Regulation within the rail, and a few wider territory
Part V widens the lens to economics, regulation, well being and organisational design. King’s regulation chapter argues that supervision has to maneuver “into the rail”, with guidelines written as executable code and brokers supervising brokers. Some of his traces are made for convention slides (“The EU is the world’s best rule-writer and a mediocre rule-executor”). Singapore, Brazil and the UAE come out forward of the US and Australia, as a result of rulemaking, supervision and funds infrastructure sit nearer collectively in these markets.
The economics chapter, co-written with Professor Richard Petty, argues that power and grid capability, not chips, would be the binding constraint on the agentic economic system. It introduces a brand new readiness index that ranks China first, the UAE second and the US fifth. The authors say brazenly that the scores are “directional” and had been constructed with assist from AI fashions, and that the index is designed to be argued with. Dr Julia Michelin asks whether or not well being is changing into a type of capital. Ross Dawson’s Human+AI framework is essentially the most sensible steering on this half on holding human judgment significant: “An approver who rubber-stamps a recommendation has added a signature, not a judgment.”
The roadmap
For financial institution leaders, the conclusion is essentially the most helpful a part of the ebook. King argues that being a succesful digital financial institution is now desk stakes, and in addition a entice, as a result of such a financial institution is “still fundamentally architected around human latency”. He places the window to maneuver from digital-first to agentic at two to a few years: “Institutions whose AI agents are self-improving their own operations by 2029 will be uncatchable by 2035.”
He follows with a self-assessment roadmap constructed on 5 pillars: management and tradition, expertise foundations, organisational evolution, autonomous infrastructure and the agentic financial institution itself. A 3-year transformation plan then runs throughout tradition, expertise, organisational construction and AI functionality. There is a welcome dose of realism: King warns in opposition to “scorecard theater (self-scored 4s, when most banks are 1 or 2 genuinely)”.
His image of 2050 ranks the winners as AI-native banks born after 2028, then fintechs that made the leap early, with tailored incumbents mentioning the rear, which he expects to be “the smallest representative group”.
Where readers will push again
Bank 5.0 is a intentionally provocative ebook, and never each reader will settle for its certainty. King writes that “the destination is certain, but the journey is less so”, and a few of his timelines are daring. The geography leans in direction of China, Singapore and the Gulf, the place King now lives and advises authorities and trade, although he’s open about these roles. Part III carries a vendor’s perspective. The later chapters stray into power coverage, local weather, common fundamental revenue and longevity, which is able to strike some readers as a good distance from the financial institution stability sheet. And as a result of the ebook captures a subject transferring month by month, a few of its 2026 references will date shortly.
Chris Skinner, one of many ebook’s endorsers, places this greatest: “You may not agree with every forecast, but that is precisely why you should read this book.”
The verdict
King has a protracted report of being early, and Bank 5.0 is his most bold ebook but. It can also be extra of an ensemble piece than its predecessors, and the contributed chapters from Vellozo, Birch, Khalil and Holman give it depth past the writer’s personal forecasts. Bank CEOs, boards and technique groups will get essentially the most from it, and the closing roadmap alone justifies the time. Fintech founders constructing for agentic commerce will discover a helpful map of the place incumbents are weakest.
In holding with the topic, King is clear about methodology. He used AI instruments for analysis, planning and restyling the charts, however says that “all of the text that appears is human-generated.”
His closing line sums up the ambition of the entire sequence: “Banking everywhere, never with a human. Welcome to Bank 5.0.”
