Three slow stories are still doing most of the heavy lifting in 2026. Engineering tools are quietly getting better. Cloud spending is being squeezed by both CFOs and risk teams. And central banks are still trying to decide whether to cut once more or just sit still. None of these are loud, but together they describe most of what is happening in banks and tech right now.

Infrastructure as code grows up

The open source infrastructure as code stack keeps moving forward in small, boring increments. Terragrunt, the popular wrapper around Terraform that many teams adopted after the 2023 Terraform license change, just landed another round of polish on its catalog scaffolding. A terminal interface for picking modules, cleaner keybindings, better form behavior. Nothing flashy.

Boring is the point. Tooling at this layer used to be invented on a whiteboard and shipped half finished. Now it goes through pull request review, documentation updates, and a methodology page that requires an issue before code. That is what mature open source looks like.

For platform engineering teams inside banks and tech firms, this matters more than it sounds. The platform team is the group that gives every other engineer a paved road for spinning up infrastructure. If the paved road is built on flaky tools, the road breaks.

The names worth following are HashiCorp Terraform, OpenTofu, Pulumi, Crossplane, and the wrapper layer of Terragrunt. Consolidation will continue. IBM owns HashiCorp now after the 2024 deal closed. OpenTofu lives under the Linux Foundation. The split between commercial and community licensing keeps shaping which tools survive at which kinds of companies.

Cloud bills meet the FinOps team

Tech and bank CFOs are spending more time on cloud bills than they used to. The trend has a name now. FinOps. It is not glamorous and the certifications are uneven, but the practice is real.

A typical mid sized bank in Europe spends somewhere between 6 and 15 percent of its IT budget on public cloud. That figure was rising steadily until late 2024. Since then, growth has slowed at most banks. Not because they stopped using cloud, but because they finished the easy migrations and started looking at the receipts. AWS, Microsoft Azure, and Google Cloud all report slowing growth in financial services accounts compared to two years ago. The dollars are still up. The growth rate is not.

Banks have specific reasons to look hard at cloud spend. Regulators in the EU, UK, and US are now asking concrete questions about third party concentration. The Digital Operational Resilience Act in the EU, in force since January 2025, requires banks to map their critical cloud dependencies and have an exit plan that is not just a slide. That work costs money. It also exposes how much money is going to a small number of vendors.

The tech firms are responding by repackaging. AWS keeps pushing managed services that lock in workloads without looking like lock in. Microsoft uses Copilot integrations to make Azure stickier for enterprise customers. Google Cloud competes on price for storage and on AI inference for new workloads.

Central banks still cannot agree

The Federal Reserve, the European Central Bank, and the Bank of England all spent the first half of 2026 sounding cautious. The Fed held its policy rate steady through the spring. The ECB has cut twice since January but signaled it is in no hurry to keep going. The Bank of England is somewhere in between.

Inflation in the eurozone is hovering close to the 2 percent target. US core inflation has stayed sticky in the high twos. UK services inflation is still uncomfortable. Bond markets have stopped pretending they know the path. Two year US Treasury yields have spent weeks oscillating in a narrow range with no clear direction. That tells you the rate cut story is no longer a one way bet.

For banks, this matters in obvious ways. Net interest margins peaked in 2023 for most large European banks and have been grinding lower since. Deposit pricing is still competitive. Loan growth is muted in commercial real estate and stronger in mid market lending. Italian and Spanish banks have been the relative winners. Romanian and Polish banks are seeing healthier consumer credit but watching cost discipline carefully.

For tech companies, the rates picture matters in a quieter way. Software valuations stopped expanding the moment real yields settled above zero. Free cash flow is the thing that matters now, not narrative growth. Companies that cannot show it are punished.

Earnings season tells the same story twice

The first quarter 2026 earnings season is essentially over. Two patterns held.

Banks reported flat to slightly lower net interest income and decent fee income from wealth management and investment banking. Trading desks had a good quarter on rate and currency volatility. Loan loss provisions ticked up but not in a way that scared anyone. JPMorgan, HSBC, BNP Paribas, UniCredit, and Santander all delivered numbers that were good enough, not exciting.

Tech splits more cleanly. The hyperscalers with AI exposure (Microsoft, Alphabet, Amazon) reported strong cloud growth and even stronger capital expenditures. Capex is the number that matters now. Microsoft alone is on track to spend around 80 billion dollars on AI infrastructure for fiscal year 2026. Meta is in a similar zone. The semiconductor names that supply this build out (Nvidia, AMD, Broadcom, TSMC, ASML) had strong quarters. Software names competing for the same engineering hours had weaker ones.

The central tension is clear. The infrastructure layer is being built at industrial scale. The application layer is still trying to figure out which AI features customers will pay for.

What this means

Platform engineering teams that build their internal paved road on stable open source IaC tools have a real edge over teams still gluing together shell scripts. The economics favor consolidation onto fewer, better tools.

Cloud cost discipline is no longer a buzzword. Banks have regulatory cover to scrutinize vendor concentration. Tech firms have margin pressure to do the same. Both effects pull in the same direction and they will keep pulling.

Central banks will probably stay cautious through the summer. Anyone betting heavily on aggressive rate cuts before autumn should look at the yield curve and ask what the bond market is actually telling them.
