AI and the future of work
McKinsey MGI: Agents, robots, and us — how AI reshapes work and skills in Europe (May 12)
McKinsey Global Institute surveyed Europe's labor landscape in a world of AI agents and physical robots. The central finding: most skills people use today will still be needed, but how they are used will shift as workers collaborate with intelligent machines rather than simply performing tasks independently. 1
The report maps which tasks within jobs are most exposed to automation and finds that automation will affect workers across all skill and wage levels — not just routine or low-wage roles.
Bain: The future of opex in the agent economy (May 2026)
Bain argues that enterprise operating cost structures are heading toward a fundamental split: within a few years, 20–30% of today's headcount costs could be replaced by AI token costs, shifting the dominant cost driver from people to compute. 2
Key data from early enterprise deployments:
- The top 5% of users in an organization already consume more tokens than the remaining 95% combined
- Even at 1–2% of total operating expenditure, unbudgeted token costs are showing up mid-quarter as surprises for general managers
- For a 10,000-person engineering organization, total token spend is large enough to register as an unanticipated budget line
The broader implication: organizations still thinking of AI cost as an IT line item are misreading the structural shift. Token budgets and headcount budgets will increasingly compete directly.

Deloitte: AI agents are scaling faster than their guardrails (April 24)
A Deloitte survey of 3,235 IT and business leaders across 24 countries found that agentic AI adoption is running well ahead of governance. 3
- Only 21% of respondents report mature governance in place for agentic AI
- By 2027, 74% expect their companies to use AI agents at least moderately; 23% expect extensive use
- Deloitte's conclusion: organizations that skip governance design to accelerate experimentation will face higher costs and more risk — not less — when scale problems surface
BCG: Trust Imperative 5.0 — AI governance frameworks (May 28)
BCG's annual trust report finds that most governments have built foundational principles and frameworks for AI, but organizations still struggle to apply them consistently in practice. The gap between formal policy and operational reality is widening as agentic deployments outpace compliance teams' ability to audit them. 4
Finance, banking, and wealth
McKinsey: Global Banking Annual Review 2026 — precision with speed (May 21)
McKinsey's flagship banking report for 2026 previews four interconnected shifts for the industry: continued strong financial results in 2025, a redrawn competitive map, a tipping point in customer ownership (where banks risk losing the relationship layer to tech platforms and non-banks), and AI remaking bank operations at an "unprecedented" pace. 5
The report's thesis is that the banks gaining advantage are not simply investing in AI — they are restructuring as "multispeed organizations," running stable regulated business lines at one cadence and AI-driven customer and product layers at another.
BCG: Global Wealth Report 2026 — the great reordering (May 27)
BCG's annual wealth report offers the most data-dense reading on where financial assets are accumulating globally. 6
Key figures for 2025:
- Global financial wealth rose 10.7% to $333 trillion, the highest growth rate since 2021
- Including real assets, total net wealth reached $550 trillion, up 9.3%
- Equities led gains at +13.2%; gold surged ~44%
- Hong Kong overtook Switzerland as the world's largest cross-border booking center, with cross-border wealth rising 10.7% to $2.9 trillion
- Mainland China grew financial wealth 15%, with 9% annual growth projected through 2030
The forward outlook: global financial wealth projected to grow at a 7% CAGR through 2030, contingent on geopolitical tensions easing in the second half of 2026.

BCG: The future of digital assets in finance (May 18)
BCG frames digital assets as no longer a niche phenomenon but a structural force reshaping payments, capital markets, and post-trade infrastructure. The report distinguishes three categories that leaders need to treat separately: crypto (the current largest revenue pool), stablecoins and digital money (gaining traction in treasury and settlement), and tokenized real-world assets (small today but deepest long-term relevance). 7
The strategic framing is dual: digital asset scaling threatens net interest income and legacy post-trade economics for banks, while simultaneously creating new opportunities in custody, tokenized funds, collateral mobility, and trading. BCG advises building "strategic optionality" rather than picking a single winner.
BCG: Fintech — from recovery to resurgence (June 1)
BCG's fintech report published this morning marks the sector's entry into a more demanding phase: growth and profitability are recovering, but closer public-market scrutiny and heavier compliance burdens are narrowing the margin for error. 8
The thesis: fintech has moved past its post-2022 correction, but the path to durability now runs through regulatory maturity and unit-economics discipline rather than growth-at-all-costs. The winners from here will look more like regulated financial institutions than venture-funded challengers.
Operations, manufacturing, and supply chain
McKinsey MGI: Ramping up manufacturing in America? (May 21)
MGI examines how much domestic manufacturing expansion would actually be needed to meaningfully reduce US trade dependencies. The answer: a great deal — and the scale required is larger than most policy discussions acknowledge. 9
The report uses Bureau of Labor Statistics data through March 2026 as its baseline, noting that total US employment grew only 0.1% in 2025, versus 0.9% in 2024 and 1.6% the year before — a backdrop that makes rapid industrial workforce expansion harder.
BCG: How the factory of the future is reshaping manufacturing competitiveness (May 28)
BCG finds that AI is actively narrowing the labor cost gap between high- and low-cost manufacturing countries. As the cost advantage of offshoring shrinks, companies face a decision that can no longer be deferred: upgrade or relocate? 10
BCG's framing is that getting this decision right — factoring in AI-enabled productivity at existing sites, not just current labor costs — will define competitive position for the next decade.
Consumer sentiment and healthcare
Deloitte: State of the US consumer — April–May 2026 (May 8)
Deloitte's monthly ConsumerSignals tracker for April–May 2026 shows a consumer in a tug of war between a deteriorating outlook and continued actual spending. 11
Key readings from March–April data:
- Financial well-being index retreated to 101.1 in March, giving back most of February's gains — driven by weakening future expectations rather than current financial stress
- 82% of consumers expect higher gas prices (up 35 points month-on-month, the highest in three years); 74% expect higher grocery prices
- Discretionary spending intentions partially recovered in April after a steep March drop, but remain well below January levels
The pattern: consumer behavior is diverging from consumer sentiment. People are still spending, but they are increasingly anxious about what comes next.

McKinsey: How provider-led health plans can succeed in commercial insurance (May 20)
McKinsey's analysis of provider-led health plans (health systems running their own insurance products) finds significant underrepresentation in the commercial group insurance market. The gap represents more than $20 billion in potential revenue and $700 million in operating margin left uncaptured by health systems that have the patient relationships and clinical data to compete. 12
