Korean Banks’ Margins Seen at Four-Year Low on Rate Decline

South Korean banks may close 2013 with the lowest profitability in four years as central bank rate cuts meant to stimulate Asia’s fourth-biggest economy squeeze loan margins further.

Three rate decreases by the Bank of Korea since July 2012 have left borrowing costs near a three-year low and average net interest margin for lenders, including Shinhan Financial Group Co. (055550), at the lowest since 2009, according to Financial Supervisory Service data.

“Rate reductions since last year have slammed into the banks’ interest margins,” said Taye Shim, a Seoul-based analyst at Daewoo Securities Co. who forecasts the gauge will slip to an average 2.28 percent in 2013 from 2.51 percent last year at the nation’s seven biggest banks. “Loan margin will probably show mild growth from 2014 after hitting a bottom in the second half of this year.”

While the Bank of Korea today cut its growth forecast for next year, it still expects the expansion to accelerate. Faster growth and prospects for global rate increases may lift profitability at South Korea’s seven biggest banks including KB Financial Group Inc. by an average 10 basis points next year from 2013, according to four analysts surveyed by Bloomberg.

South Korea’s economy will expand 3.8 percent in 2014, slower than the 4 percent previously forecast, the central bank said. It left its projection for 2013’s growth at 2.8 percent. It also kept the benchmark interest rate unchanged at 2.5 percent for a fifth month to bolster the economic rebound.

Profit Drop

The nation’s lenders since 2011 have cut executive ranks and closed unprofitable branches to preserve profit amid tightening margins and sluggish credit demand.

The average net interest margin at the country’s 18 banks was 2.1 percent last year, the lowest since 2009, following the global financial crisis, FSS data show. It dropped to 1.88 percent at the end of the second quarter, resulting in a 56 percent slump in lenders’ combined net income compared with a year earlier, the data show.

Net interest margin for Southeast Asian banks averaged 4.5 percent and 2.9 percent for banks in the world’s top 20 economies, including South Korea, according to data from the companies’ latest filings compiled by Bloomberg.

Combined second-quarter interest income for Korean lenders stood at 18 trillion won, the lowest level since at least 2009, according to the regulator.

Rate Gap

The time lag between adjustments on loan rates and the rates banks pay on deposits has deepened the impact of central bank rate cuts on banks’ profitability, according to Kim Jae Woo, an analyst at Samsung Securities Co.

Interest rates on almost 80 percent of the country’s outstanding loans are variable and adjust quarterly to reflect benchmark rates. That compares with the average 12-month term for time deposits at Korean banks, he said.

The interest rate spread in August between what South Korean banks charge customers on new loans, and the amount banks pay customers on time deposits, narrowed to 1.92 percentage points from 2.03 percentage points a year earlier, according to central bank data.

“Interest margin isn’t a factor banks can control as it’s closely tied to macroeconomic conditions,” said Kim Woo Jin, a senior researcher at the Seoul-based Korea Institute of Finance. “To Korean banks, whose revenue heavily relies on interest income, the low-rate environment has brought huge negatives.”

Lending accounts for about 80 percent of the banks’ profit, he said. South Korea’s total outstanding bank loans in July rose 4.1 percent from a year earlier to 1,129 trillion won ($1,048 billion), according to Bank of Korea data. Loans rose 3.4 percent last year to 1,099 trillion won, the slowest growth since at least 1999.

‘Spring Breeze’

While earnings at Korean lenders remain under pressure, the Kospi Finance Index, a gauge of 51 financial stocks including Shinhan, the country’s biggest banking group by market value, and Woori Finance Holdings Co., has risen 2.5 percent this year. The index’s gains indicate some investor optimism for the industry’s prospects as the wider benchmark Kospi Index gained 0.2 percent this year.

The net interest margin for Korean banks is likely to get a boost as the rate gap between loans and deposits narrows and the Bank of Korea raises rates along with global peers, according the analysts surveyed by Bloomberg.

The central bank will increase its benchmark rate to 2.75 percent in the third quarter of next year, according to the median forecast in a survey of 22 economists by Bloomberg News.

Cautious Optimism

“I’m cautiously optimistic about the Korean banking industry from the second half onward,” said Im Jeong Jae, a Seoul-based fund manager at BNP Paribas Asset Management Co., which oversees about $35 billion in assets. “We seem to have left the worst behind in the second quarter as far as interest margin and credit cost. Korean banks may finally see the long-waited spring breeze next year.”

The central bank’s rate cuts have also contributed to Korean household debt rising to a record 980 trillion won in June, making the prospect of higher rates a threat to the country’s economic growth as borrowers pay more to service debt when rates rise.

Swelling Debt

Swelling household debt, the biggest risk to the nation’s financial system, according to a Bank of Korea survey of 90 experts and fund managers in January, has spurred banks to boost bad-debt provisions by 10 percent to 2.7 trillion won at the end of the second quarter, further eroding earnings.

“The three core variables for banking stocks -- net interest margin, credit costs and loan growth -- all have shown a negative picture in the past couple of years,” Im said.

Standard Chartered Plc, the London-based bank that earns about three-quarters of its profit from Asia, said in August it would take a $1 billion write down on the value of its Korean business and characterized the country as its “most difficult market.”

“South Korean banks will need to accept the structural changes of a low-growth era,” said Korea Institute of Finance’s Kim. “The country no longer has the growth potential of an emerging nation like Indonesia and Malaysia. Banks need to find a way to reduce their dependence on interest income and cut back costs, which won’t be resolved overnight.”
