Behavioural Finance Increasingly Mainstream, With AI As Enabler

Behavioural finance is starting to go prime time, so its advocates say.

The term, which relates to how psychological insights unpick why people make certain financial choices, has had its cheerleaders for decades. Given market gyrations and worries that far too many people reside in low-yielding cash because fears of loss put them off, behavioural finance is not merely an academic pursuit.

A problem, however, is that harnessing these ideas in real-time requires immense number-crunching capabilities that had, until a few years ago, been beyond the armoury of wealth management. But AI has changed that.
 
In September, US-based investment manager launched a Personalised Investor Engine (PIE), a behavioural-intelligence platform designed to help financial institutions convert savers into investors. It has launched PIE with Zopa, applying the technology across the digital bank’s 1.5 million mass-affluent customer base. 

Built with behavioural science expertise from , a technology and behavioural finance company, PIE uses behavioural profiling to identify individual barriers and tailor interventions at key points in the customer journey. The platform was informed by a 6,000-participant Invesco research study into why savers stay in cash. Crucially, it found that external trust in institutions and internal self-confidence are distinct barriers requiring different interventions, and that rising cash balances tend to deepen fear of loss rather than easing it.

The hope is that putting money in motion will benefit the wider industry, ease strains on public finances as citizens build capital for retirement, and will lift wealth in general. 

Using AI-driven tools to help with behavioural investing insights is a “win-win for firms, people and policymakers,” Greg Davies (pictured below), head of behavioural finance, Oxford Risk, told this publication in a recent call.

“I have been doing this ,” he said. “The financial industry is still in the foothills of what’s possible.”

The Invesco deal is significant, given that the US-headquartered firm carries plenty of investment muscle, with $2.453.5 trillion of assets under management at the end of October. 

Reluctance to invest is less of an accessibility problem; it is more about the worry of losing money. Building comfort is important to get investors to take a step forward, Sonia Bainbridge (pictured below), head of digital distribution, EMEA, Invesco, said when the product launch was announced. There is an estimated €10 trillion ($11.5 trillion) being held in cash across Europe.

“Our research suggests the challenge is no longer access, it's activation. Fear of loss, low confidence and uncertainty about making the right decision continue to prevent many people from turning intent into action,” she said. 

The field of behavioural finance continues to develop. As reported here in 2022, it is the “dominant differentiator” in the philosophy and marketing strategy of more and give them lots of numbers, then people think 'we’ve done our job and that should convince everyone they should be investing’,” he continued.  

Nudging and encouraging people to invest will not work without personalising the investment experience, Davies said. That’s where the value of AI with its ability to handle data comes in. 

“AI has dramatically reduced the cost and complexity of delivering personalised engagement at scale. But that makes the quality of the underlying behavioural science and decisioning models even more important,” Davies said. “The AI shouldn't be inventing the answer; it should be using robust, validated models to determine what support different investors need,” he said.
