Good morning. Top accounting talent remains essential in the financial services industry. And a "near miss" that almost cost Citigroup trillions is a good example of why. 

The Big Bank intended to send $280 to a customer account, but instead credited the account with $81 trillion, the Financial Times reported on Friday. The mix-up occurred last April when an erroneous internal transfer was missed by a payments employee. And then, a second official, tasked with checking the transaction before it was approved to get processed at the start of business the following day, missed the error as well.

Fortunately for Citi, a third employee came to the rescue and detected a problem with the bank’s account balances. The employee caught the payment 90 minutes after it was posted. Several hours later, the payment was reversed, according to the Financial Times.

"Despite the fact that a payment of this size could not actually have been executed, our detective controls promptly identified the inputting error between two Citi ledger accounts, and we reversed the entry," a Citi spokesperson told me via email. "Our preventative controls would have also stopped any funds leaving the bank."

The mixup didn't harm the bank or Citi's client, according to the spokesperson, but the episode "underscores our continued efforts to continue eliminating manual processes and automating controls through our transformation." The firm did not confirm the dollar amount of the transaction.

Regarding Citi’s transformation, the company spent $11.8 billion on technology in 2024, CFO Mark Mason said during its Q4 2024 earnings call in January. The focus was on “digital innovation, new product development, client experience and other areas such as cybersecurity,” Mason said. 

Stacey Ritter, assistant professor of accounting at Santa Clara University’s Leavey School of Business, researches firm behaviors in financial accounting and auditing. I asked for her assessment of Citi's situation. 

“Human error is inevitable, which is why strong accounting policies and controls are essential—not just to prevent mistakes, but to detect and correct them quickly,” Ritter said. Although an error occurred at Citi, it was identified and remediated within 1.5 hours, she said.

Last year, Citi had a total of 10 "near misses" of $1 billion or greater, the Financial Times reported. Near misses are when a bank mistakenly credits a customer's account with the wrong amount but can recover the funds.  

“For CFOs and chief accounting officers, the key to minimizing these risks is maintaining robust controls and attracting top accounting talent,” Ritter said. However, the accounting profession is facing a significant pipeline problem, and companies are already feeling the impact, she said. 

“We’ve seen an increase in financial restatements, and as this case highlights, operational disruptions can occur when businesses rely on internal accounting data for critical decisions,” she explained. 

There's a growing shortage of certified public accountants as seasoned practitioners are retiring. Meanwhile, accountants with heavy workloads are experiencing burnout. At the same time, it has become a challenge to attract the next generation of accountants. 

But incorporating technology in the workplace could be a draw, Steve Zabel, the CFO of insurance benefits provider Unum Group recently told me. It’s crucial to provide employees in finance and accounting roles “an experience that feels modern,” Zabel said.
