McGeever: ROI-America Inc.'s productivity boom could be global.

The U.S. economic system is experiencing a productivity boom, and it may even be spreading globally.

Artificial intelligence (AI) is expected to accelerate these trends. However, there are some early signs that AI's benefits may be spreading.

The Purchasing Managers' Index (PMI), released on Friday, showed that British businesses have started the year off on a high note. Demand at home and abroad has been robust. This is the fastest growth in output since April 2024.

The pace of job loss has also increased since December. Since late 2024, the sub-indices of employment in Britain's PMI have been below that threshold which separates expansion from contraction.

The UK appears to be increasing the amount of goods produced per hour of work - the textbook definition for productivity growth.

The latest German PMI data also revealed a similar picture, albeit a little grainier. The output in January was at its highest level in three months. Employment fell at the fastest rate since November 2009 - excluding pandemic declines.

It's true that PMI data doesn't always match up with official statistics on growth and employment, but one shouldn't put too much weight in any single month's results.

The burgeoning trend should not be ignored. JP Morgan economist Allan Monks points out that the UK's ratio of output per employee - a crude proxy for productivity – is at its highest level since August 2013 - even after excluding distortions caused by pandemics.

Bruna Skarica, a Morgan Stanley analyst, agrees, writing that "a degree of skepticism is probably warranted around the PMIs, but the dynamics of resilient growth, and sluggish labor demand, merits more consideration."

LONG-TERM PATIENTISM

What's ?driving this? It's probably the AI and technology frenzy. Businesses are betting that AI can make them more innovative, productive and cost effective.

However, it remains to be determined whether the AI revolution can help the rest of?the world to narrow the gap in productivity with the United States.

This seems to be a better option in China. China's economy has already seen significant productivity increases in some sectors, such as autos, steel and high-value goods.

Goldman Sachs economists estimate that computing capacity in China will double over the next five year period.

It's another story in Europe. The continent is often viewed as a weak point in the global value-chain, with low productivity and growth potential. Economists attribute this to a lack of innovation in technology, excessive regulation, high public debt, and low private investments.

Goldman Sachs economists estimate AI will only add a "meaningful" 0.2 percentage points per year to European growth over the next few decades.

The?U.S. The U.S. is expecting to see a productivity boost of 0.4 pp per year.

PRODUCTIVITY A 'GET OUT OF JAIL FREE' CARD?

Federal Reserve Chair Jerome Powell signaled in December that productivity growth can help the central banks reduce inflation, while maintaining a policy of "dovishness" to support the economy and labor market.

Productivity gains that are faster tend to be deinflationary. Central banks could avoid making drastic interest rate changes if productivity increases accelerate and spread globally.

The flip side is that it could be more difficult to maintain full employment if AI advancements allow economies flourish with far fewer workers. Powell could have more to share on this topic when the Fed meets next week.

All of this, of course, should be taken as a pinch of salt. Even at the best times, productivity figures can be a bit shaky and difficult to measure accurately. As with the flawed data that was revealed in Britain's Office for National Statistics last year, productivity estimates are also affected by this.

Investors are betting that AI will lead to a productivity boom. This may be revealed by the earnings of U.S. megacap tech companies including Meta, Microsoft and Apple.

There are still many unknowns, but there is some evidence that the AI spending could lead to a global economic boom.
