Summary
Bank stocks benefited from rising interest rates in the first half of 2022, but valuation losses on securities holdings and provisioning burdens cut into net profit, blocking a valuation re-rating.
According to the Financial Supervisory Service's August 2022 announcement, domestic banks' first-half net profit came to 9.9 trillion won, down 1.1 trillion won, or 9.9%, from a year earlier. What this really shows is that a wider loan-deposit spread alone is not enough to drive a re-rating of bank stocks.
What Happened
Domestic banks' interest income in the first half of 2022 came to 26.2 trillion won, up 4.1 trillion won, or 18.8%, from 22.1 trillion won a year earlier. The net interest margin (NIM) — a profitability measure that subtracts funding costs such as deposits from the yield on interest-earning assets such as loans — rose 0.12 percentage points, from 1.44% to 1.56%.
The problem lies further down the income statement. Non-interest income fell to 1.7 trillion won, down 3.2 trillion won, or 65.1%, from 5 trillion won a year earlier. When interest rates rise, the rates on new loans go up, but the prices of bonds banks already hold go down. That's why banks' securities-related gains and losses swung so sharply.
Credit loss provisions rose in tandem. Domestic banks' credit loss provisions in the first half of 2022 came to 3.1 trillion won, up 1.1 trillion won, or 54.0%, from 2 trillion won a year earlier. Rising rates lift banks' revenue per unit, but they also raise the repayment burden on borrowers. That's why the market doesn't view bank stocks simply as high-rate beneficiaries.
Structural Background
A high-rate environment has two faces for the banking industry. In the first phase, increases in the benchmark interest rate and market rates feed through into loan rates, improving the net interest margin. In the next phase, funding costs catch up, and an economic slowdown feeds through into delinquency rates and provisions.
In this data, what the market has already priced in is the rise in interest income. What it hasn't yet fully priced in is the volatility of non-interest income and the provisioning cycle. ROA fell 0.14 percentage points to 0.58% from 0.72% a year earlier, and ROE dropped 1.43 percentage points to 8.09% from 9.53% a year earlier. It's capital efficiency, more than the absolute size of profit, that has slowed.
Impact on Stocks and the Sector
- KB Financial Group: Large financial holding companies are the first to reflect NIM improvement during a rate-hike cycle, but if bond valuation losses and provisions grow, a discount to price-to-book ratio (P/B) remains a lingering headwind.
- Shinhan Financial Group: The banking unit's interest income holds up well, but group-wide net profit volatility increases when the trading-related gains and losses of non-bank affiliates such as card and securities units swing.
- Hana Financial Group: Its exposure to foreign exchange and corporate banking is an investment point, but when exchange rate and interest rate volatility rise together, the quality of non-interest income needs closer scrutiny.
- Woori Financial Group: In a structure heavily dependent on banking, NIM improvement is a direct positive catalyst. However, a thin non-bank portfolio also leaves a discount tied to limited revenue diversification.
- IBK (Industrial Bank of Korea): As a policy bank with a high share of loans to small and medium-sized enterprises, its sensitivity to provisions could stand out more sharply when the economy slows.
Bullish vs. Bearish Scenarios
The bullish scenario is one where rates stay elevated without spiking further. In that case, banks can continue to benefit from loan-rate repricing while limiting the expansion of valuation losses on bonds they hold. If the net interest margin holds and the growth rate of credit loss provisions slows, the dividend appeal of bank stocks could move back to the forefront.
The bearish scenario is one where rising rates lead to an economic slowdown and higher credit costs. The 18.8% increase in interest income has already been confirmed in the numbers. But the 65.1% drop in non-interest income and the 54.0% rise in credit loss provisions are counter-evidence that banks' earnings power can't be explained by interest rates alone.
Investor Action Points
- Check whether the net interest margin stays at 1.56% or above in banks' next-quarter earnings. If the NIM turns down, the rate-beneficiary thesis weakens.
- Watch securities-related gains and losses alongside the direction of Korean Treasury bond yields. If rates surge again, bond valuation losses could weigh on non-interest income.
- Watch whether the year-over-year growth rate of credit loss provisions slows from 54.0%. If provisions keep rising, dividend expectations will be overshadowed by shrinking earnings.
- Monitor the Monetary Policy Board's benchmark interest rate decisions together with the won-dollar exchange rate level. Exchange rate instability can simultaneously shake foreign investors' supply-demand (order flow) in bank stocks and banks' funding costs.
Frequently Asked Questions
Why did bank stocks' net profit decline?
Domestic banks increased interest income to 26.2 trillion won in the first half of 2022, but non-interest income fell 65.1% to 1.7 trillion won. Valuation losses on securities from rising rates and higher credit loss provisions offset the improvement in interest income.
Is rising interest rates a positive catalyst for bank stocks?
Early in a rate-hike cycle, an improving net interest margin acts as a positive catalyst for bank stocks. However, if rates rise further, falling bond prices, higher deposit funding costs, and increased borrower defaults follow, weighing on multiples.
What indicators should bank stock investors watch?
Bank stock investors should look at the net interest margin, non-interest income, and credit loss provisions together within the same quarter. As in the first half of 2022, even if the NIM rises to 1.56%, net profit can still decline if non-interest income and provisions worsen.
