A closer look at what is happening inside the business

A bank's statements are read with a bank's own questions: credit quality, margin, liquidity, funding.

01

Is credit clean?

Credit Quality

●

Is asset quality deteriorating?

Direct credit indicators remain incomplete, but this quarter shows a notable split: credit cost rose to 1.69% while reserve buffer also edged up to 3.52%.

Reserve buffer on gross loans is around 3.52%. LDR stands at 94.7%.

Credit reading currently relies mainly on credit cost and reserve buffer; NPL, group-2, and bad-debt coverage signals will be added next.

02

Is interest margin sustainable?

Interest Margin Quality

▼

Is spread coming under pressure?

Spread deserves closer monitoring because funding cost is already at 4.24%, even if pressure is not yet as severe as in clearer compression cases.

In the period, NIM reached 3.31%, −0.4pp YoY; asset yield was 7.56%, +0.1pp; while funding cost was 4.24%, +0.5pp. This suggests spread has become less favorable than before, though not yet in a clearly deteriorating two-sided way.

Funding cost is elevated

Funding cost is 4.24%, pressuring net interest margin.

Earnings Mix

▲▲

Is profit coming from core or supporting income sources?

Earnings remain primarily core-led, with NII contributing around 81.3% of total operating income. More broadly, the revenue mix is becoming less anchored in core income, as the share of net interest income declines without a clear enough offset from fee income.

Nii accounts for 81.3% of toi, fee income is 9.7% of toi, other income is 5.3% of toi, cir stands at 39.4%, net profit equals 14.6% of toi.

Income mix quality deteriorating

Net interest income share is declining while fee income does not offset enough or other income rises, making the revenue mix less anchored in core income.

Is liquidity safe?

Funding & Liquidity

●

Are funding and capital buffers sufficiently safe?

Funding and liquidity look more balanced, with LDR at 94.7% while customer funding share is improving.

Ldr stands at 94.7%, equity equals 7.2% of assets, customer funding accounts for 78.7% of interest-bearing funding, market funding accounts for 21.3%.

Research synthesis

What this reporting period is showing

STB bank investment takeaway — provision dominated. [Placeholder for EN translation.]

  • [Placeholder for EN evidence line 1.]
  • [Placeholder for EN evidence line 2.]
  • [Placeholder for EN conclusion.]

Questions for the next period

  1. Track whether the recent provision relief is sustainable or only a temporary favorable base before credit costs revert higher.

  2. Track whether the recent shift back toward customer funding can hold, rather than proving to be only a short-term quarterly improvement.

  3. Track whether core income can remain the main earnings anchor while fee income continues to broaden in a sustainable way.
