Bank of England Questions the Economic Impact of the AI Boom

Despite billions of dollars spent on artificial intelligence, the technology has delivered only small productivity gains for British businesses. The central bank notes that this massive spending has not created the economic revolution that tech companies promised.

In its latest Monetary Policy Report, the Bank of England found that AI has increased UK productivity by an estimated 0.5 percent over the past three years. That equals just 0.1 to 0.2 percentage points of extra annual productivity growth since early 2024. Even industries expected to benefit the most, such as information and communications, have seen productivity improve but have not exceeded their pre-pandemic averages.

Instead of boosting daily work output, AI-related activity is mostly helping the economy through the building and selling of the technology itself. The bank estimates that AI development has accounted for just under a fifth of UK gross domestic product growth since early 2026. Selling AI tools is proving much more profitable than using them to make other businesses more efficient.

The bank also warns that some recent productivity increases come from companies hiring fewer workers while keeping output steady, rather than from AI. Businesses are adjusting staffing after the pandemic and responding to higher labor costs. Surveys show that AI has had almost no overall impact on employment so far, though it is making some employers less likely to hire new staff or replace departing workers.

Other studies show that businesses everywhere are still waiting for a return on their investments. A survey by the National Bureau of Economic Research involving nearly 6,000 executives across the United States, United Kingdom, Germany, and Australia found that more than 80 percent of firms saw no noticeable impact from AI on employment or productivity,. A separate survey by Gartner found that while three-quarters of corporate board members expected AI to cut costs and improve productivity, only 3 percent had reached those goals.

Financial watchdogs are starting to worry about the growing gap between spending and actual returns. The International Monetary Fund warned that heavy spending on AI could harm investors if profits fail to appear, which could drag down the broader economy. The Bank for International Settlements compared the current spending rush to the dotcom boom of the 1990s, warning that tech giants are committing huge sums based on assumptions of massive future returns.

Even so, AI is already changing prices by driving up demand for memory chips and other hardware. This surge has pushed up export prices in China and other Asian economies, which in turn raises import costs for Britain. While companies wait for an AI productivity boost, the costs of the boom are already moving through the economy.

The Bank of England has not written off the technology completely. Businesses surveyed expect AI to add about 0.9 percentage points to annual productivity growth over the next three years, split between faster output and slower hiring. For now, the AI industry's most successful trick seems to be convincing businesses to keep opening their wallets.

Summary

The Bank of England's findings show a wide gap between the massive amounts of money spent on artificial intelligence and the actual productivity gains businesses are seeing. While tech developers are profiting from selling AI tools, everyday companies are still waiting for the technology to improve their bottom lines, raising concerns among financial watchdogs about a potential market bubble.
