Threat of deposit exodus haunts Japan’s regional banks

This month, Japanese digital lender Sony Bank began offering customers a yen deposit account with a taster annualised interest rate of 10.52 per cent — a startling return in a country where savings have earned almost nothing for nearly two decades.

For many of Japan’s 62 regional banks, such aggressive competition from online challengers threatens to spark an exodus of deposits at a time when higher benchmark interest rates overseas and the end of negative rates at home are fuelling concerns about the quality of their assets and the viability of their weakest borrowers.

An outflow of deposits would add to the challenges facing regional banks and Japan’s 264 shinkin co-operatives, already threatened by demographic change and the loss of population to Tokyo and other big cities.

At regional lender Shizuoka Financial Group’s earnings presentation in May, chief executive Hisashi Shibata said it was losing some retail deposits to digital banks and pledged to strengthen efforts to prevent outflows.

The same month Jimoto Holdings, which operates two regional banks in northeastern Japan, was in effect brought under state control after logging its biggest loss and failing to repay funds owed to the government.

Jimoto blamed its losses on hits to its overseas bond portfolio from rates that remain much higher in the US and Europe than a few years ago and on deterioration of its Japanese borrowers’ businesses.

“There could be more cases like Jimoto,” warned the chief executive of one regional bank. “While the financial system is stable at the moment, authorities do have a sense of crisis and if they see a risk, they will nip it in the bud.”

While investors, credit rating agencies and Japanese authorities have historically paid close attention to the potential fragility of regional banks’ assets, they have not needed to worry much about deposit flight. 

But Japan’s online banks have recorded accelerating growth in deposits and account openings. So far in 2024, Rakuten Bank, for example, has opened some 800,000 accounts.

Analysts say elderly Japanese people are increasingly opening online bank accounts with help from their adult children, posing a threat to regional banks that have a relatively old customer base.

David Threadgold, Japanese banks analyst at Keefe, Bruyette & Woods, said the shift by many regional bank customers to online banking meant they had “immeasurably greater” ability to move money just as competition for deposits mounts.

“Traditional banks do want to move people on to devices because that makes it easier to close branches and ATMs. What that means, though, is that they’ve created an ecosystem that makes it extremely easy for existing customers to go elsewhere,” said Threadgold.

For the Bank of Japan, which in March raised borrowing costs for the first time since 2007, concern about the health of regional lenders is a reason to be cautious about further rate increases.

“For many banks, a rise in interest rates will have a positive impact on their financial conditions when their interest rate-related assets and liabilities come up for renewal,” the central bank said in its most recent Financial System Report.

However, in a comment widely understood to refer to the regional banks, the bank highlighted “uncertainty over the stickiness of deposits”.

Officials at Japan’s Financial Services Agency say there is no evidence yet of a serious exodus of deposits from regional banks towards online lenders or Japan’s three megabanks. They also note that the high taster rates offered by some digital banks will not be sustainable.  

Kensuke Ogawa, an analyst at Moody’s Ratings, played down any immediate risk of large outflows.

While smaller regional banks and Shinkin co-operatives had lost deposit market share to megabanks, the regional banks that Moody’s rates had large pools of loyal customers whose salaries or pensions were paid into their accounts, he said. 

“Despite competition from megabanks and new entrants, rated regional banks’ deposit market share has remained broadly steady over the past five years,” Ogawa said.

Analysts say the online banks, which are lower-cost operations than regional banks, are offering extraordinary rates in the hopes of winning a bigger future prize: the wave of inheritance that will occur over the next 10 to 15 years from Japan’s postwar baby boomer generation.

According to the BoJ, roughly half of all Japan’s financial assets are held by the over-60s, and about a quarter by the over-70s. When elderly people in the…
