SEABANK Why a 19% Net Interest Margin Still Isn't Enough

A Sea Group Bank Still Learning How Much to Lend

PT Bank Seabank Indonesia is the Indonesian digital-banking arm of Sea Limited - the Singapore-based internet group behind Garena and Shopee - built on a small conventional lender the group acquired and rebranded (the bank's old name, PT Bank Kesejahteraan Ekonomi, still shows up in some of its regulatory paperwork). Sea Limited holds 85% of the bank through PT Danadipa Artha Indonesia; the remaining 15% sits with PT Koin Investama Nusantara. There is no third shareholder, no free float, and no independently listed equity or debt of any kind - this filing exists purely because Indonesian banking regulation (OJK's transparency and publication rules for commercial banks) requires every licensed bank, public or private, to publish its quarterly financial position, not because SeaBank itself is traded anywhere.

The economic bet is the same one every app-based deposit gatherer makes: pull in savings and time deposits cheaply through a banking app (leaning on Sea's existing Shopee/Garena user base for distribution), then lend that money back out at a rate a traditional bank branch network couldn't easily match. This is SeaBank's filing for the quarter ended June 30, 2023 (published by the bank's own directors on August 11, 2023) - the first one available to build a Recursive Gains history from - and it shows that loop only half-working: the lending side is pricing loans at a very high yield when it does lend, but the bank is currently sitting on a lot more deposits than it's choosing to lend out, and provisioning against the loans it has made is growing faster than the income those loans generate.

The Prescription

SeaBank's own numbers already prove it can underwrite a loan book at genuinely high yield - net interest income more than doubled year-on-year and NIM^» sits above 19%, a level few conventional banks in Indonesia get anywhere near. The move that compounds from here is putting more of the bank's own cheap, growing deposit base to work in that same high-yield lending it's already proven it can price - not sitting on deposits at a 60.9% loan-to-deposit ratio^» while collecting more of them every quarter. A digital bank whose whole edge is cheap funding only turns that edge into an actual business once the money gets lent, not while it's parked.

What it should stop doing: letting loan-loss provisioning run ahead of the income it's supposed to be protecting. Impairment charges^» more than tripled year-on-year (+211.6%) against net interest income that "only" doubled - and a BOPO^» ratio still sitting at 98.93% means almost every rupiah of operating income this half was consumed by costs and provisions before it ever reached the bottom line. A 483% jump in net income looks dramatic next to a year-ago quarter that barely made money at all; it isn't yet evidence of a lending book that's actually under control.

Operating Income above is the bank's own disclosed "Laba (Rugi) Operasional" line (net interest income plus the net non-interest result). This is the bare regulatory publication format Indonesian banks are required to file quarterly, with no accompanying cash flow statement.

The deposit total above is derived, not directly stated as a single line: the filing discloses Giro, Tabungan, and Deposito individually but their sum doesn't cleanly reconcile against Total Liabilities in this particular filing's layout, so the figure here is instead backed out from the bank's own disclosed 60.88% loan-to-deposit ratio against Rp14,533,163M of loans (giving ~Rp23,870,000M for June 2023), with the December 2022 figure derived the same way from Total Liabilities less the non-deposit liability lines. Treat it as a close estimate rather than a line the filing states outright.

A bank that more than doubles net interest income and still only grows operating income to Rp41.4 billion has a provisioning problem, not a revenue problem.

Key Operational Metrics

These eight ratios answer three questions: is the bank funded well, is the loan book safe, and does the margin actually reach the bottom line.

Funding & Liquidity

• Loan-to-deposit ratio (LDR^»): 60.88% (Jun 2023), down sharply from 82.43% (Jun 2022) - a bank funded well beyond what it's currently lending, and the flip side of the loan book actually shrinking 8.6% since December.

Credit Quality

• NPL^» ratio - gross: 2.09% (Jun 2023), down slightly from 2.17% (Jun 2022).
• NPL ratio - net: 0.13% (Jun 2023), down from 0.22% (Jun 2022) - kept this low by very heavy provisioning (see below), not by an unusually clean loan book.
• CAR^» / KPMM (capital adequacy): 38.75% (Jun 2023), up from 28.62% a year earlier - more than four times the regulatory minimum, and high even by the standards of a well-capitalized Indonesian bank.

Profitability & Efficiency

• NIM^»: 19.07% (H1 2023), up from 15.72% (H1 2022) - extraordinarily high for a bank, and the clearest evidence this is a high-yield digital consumer/micro-lending book, not a traditional secured-lending franchise. For comparison, Bank Mandiri reported a 5.16% NIM the same general period and BCA doesn't get anywhere close to double digits either - SeaBank's margin sits in a different business entirely.
• ROA: 0.28% (Jun 2023), up from 0.07% (Jun 2022).
• ROE: 1.33% (Jun 2023), up from 0.48% (Jun 2022) - still thin despite the enormous NIM above, because so much of the margin is absorbed by provisioning and operating costs before it reaches shareholders.
• BOPO^»: 98.93% (Jun 2023), essentially flat from 99.66% (Jun 2022) - by this Indonesian regulatory formula (which folds provisioning into operating expense), the bank is running barely above break-even.
• Cost-to-Income Ratio^» (CIR): 18.39% (Jun 2023), down sharply from 36.21% (Jun 2022) - a real efficiency gain on a formula that excludes credit costs, which is why it tells a much better story than BOPO's near-flat 99% (the two ratios aren't measuring the same thing, and a reader comparing them directly would wrongly conclude they contradict each other).

Not available in this filing: a segment or product-level breakdown of the loan book, transacting-user or merchant counts, and any deposit-cost (funding rate) disclosure - SeaBank reports as a single banking entity with no presentation deck, press release, or call transcript located for this quarter.

Beyond the Usual

The loan book is shrinking while deposits keep growing

Loans fell 8.6% between December 2022 and June 2023 even as deposits grew roughly 10.6% over the same period, pushing the loan-to-deposit ratio down from an already-moderate 82.43% a year earlier to just 60.88%. A bank this far below 100% LDR has real room to keep lending - the question worth watching in later quarters is whether this is deliberate credit-quality discipline after a rough prior stretch, or a lender that's lost its appetite to underwrite while it works through the asset-quality issues below.

Provisioning grew more than three times faster than net interest income

Impairment losses on financial assets rose from Rp829,430M to Rp2,584,397M year-on-year - a 211.6% increase - against net interest income that "only" grew 139.0%. That's why operating income of Rp41.4 billion looks so small next to Rp3.0 trillion of net interest income: nearly all of the margin the bank is earning on its (shrinking) loan book is being set aside against expected losses, not converted into profit.

The headline capital jump - and CAR jump - is a reclassification, not fresh money

Modal disetor (paid-in share capital) rose from Rp4,478,129M to Rp6,578,129M during the half - a Rp2.1 trillion increase that, on its own, would look like a large fresh capital injection from Sea Limited this quarter. It isn't one. At December 2022, that same Rp2.1 trillion was already sitting on the balance sheet as "dana setoran modal" - a capital deposit received but not yet converted into issued shares - inside the "tambahan modal disetor" (additional paid-in capital) line, which also carried a small Rp18,704M share-premium (agio) balance that never moved. Add modal disetor and tambahan modal disetor together for each date and the combined total is exactly unchanged, to the rupiah, between December 2022 and June 2023 (Rp6,596,833M both times): the cash arrived before this filing's period began, and H1 2023 is just the formal share-issuance paperwork catching up to it. The entire Rp78,728M increase in total equity this half reconciles precisely to comprehensive income for the period (Rp34,811M net income plus Rp43,917M of other comprehensive income) - not to any new capital at all. This is also why KPMM (capital adequacy) jumped from 28.62% to 38.75% year-on-year: that ratio's real move reflects capital Sea Limited actually contributed sometime before December 2022, not a shareholder move that happened during the first half of 2023. A reader comparing this quarter's enormous capital buffer to the parent's ongoing commitment should know the underlying cash event predates the period this filing covers.

Zero commitments, contingencies, or derivative exposure of any kind

Both the commitments-and-contingencies schedule and the spot-and-derivatives schedule in this filing show a flat dash or zero across every single line item, in both the current and comparative period. SeaBank is carrying no undrawn credit facilities, no guarantees given or received, no letters of credit, and no FX or interest-rate derivative positions at all - a genuinely simple balance sheet for a bank of this size, and a sign it isn't yet doing any trade-finance or corporate-guarantee business alongside its retail deposit and lending franchise.

An unusually well-reserved loan book relative to actual defaults

The loan-loss reserve against total earning assets (CKPN) rose to 7.39% of earning assets in June 2023 from 5.10% a year earlier - more than 50 times the net NPL ratio of 0.13% for the same period. That's a bank reserving far more conservatively than its realized default rate alone would require, which flatters the net NPL number reported above but also means a meaningful chunk of this half's provisioning charge is precautionary rather than tied to loans actually going bad yet.

Target Valuation Range

No numeric valuation range is computable for SeaBank: it has no independently traded equity or debt, so no share price, market cap, or P/E/P/B multiple exists to anchor one.

SeaBank Indonesia has no independently traded equity or debt - Sea Limited (through PT Danadipa Artha Indonesia) and PT Koin Investama Nusantara are its only two shareholders, and neither has ever floated any portion of the bank on a public market. There is no share price, no market capitalization, and no P/E or P/B multiple that can honestly be built for this entity, so none is estimated here. Sea Limited itself trades on the NYSE (ticker SE), but that reflects the entire Sea Group - gaming, e-commerce, and digital financial services together - not SeaBank Indonesia's standalone economics, and folding a group-level multiple back onto one subsidiary bank would misrepresent both.

A bank can post a 19% margin and still be a work in progress: SeaBank is proving it can price risk, not yet proving it's willing to lend, and until the loan-to-deposit ratio and the provisioning line move together in the same direction, the eye-catching NIM is a capability, not a result.
