Record Quarters for Foreign Banks as Korea's Crypto Exchanges Slide

Korea’s second-quarter earnings season delivered a sharply split verdict on August 14: the local units of two global banking groups reported the best quarters in their history, while the country’s two dominant cryptocurrency exchanges disclosed steep deterioration — one swinging to a loss outright. The divergence, drawn from a single day of corporate disclosures, sketches a financial sector in which regulated deposit-taking franchises are compounding gains while fee-driven digital-asset platforms absorb a sustained downturn.

Two Foreign-Owned Banks, Two All-Time Records

SC First Bank, the Korean arm of Standard Chartered, reported net profit of 319.6 billion won for the April–June quarter, a 230.5 percent jump from a year earlier and the largest quarterly profit the bank has ever recorded.

Citibank Korea followed the same script at smaller scale. The bank posted second-quarter net profit of 186.8 billion won, up 86 percent year-on-year and likewise an all-time quarterly high.

That two foreign-owned lenders — both of which have spent recent years narrowing their Korean retail footprints to concentrate on corporate and institutional banking — printed record results in the same quarter suggests the slimmed-down model is now translating directly into bottom-line leverage.

The Crypto Ledger Runs the Other Way

The day’s disclosures from Korea’s digital-asset industry told the opposite story. Bithumb reported a net loss of 21.8 billion won for the second quarter, with revenue down 35.8 percent.

Dunamu, operator of the far larger Upbit exchange, stayed profitable but not comfortably so: net profit came in at 38.9 billion won, a 60 percent drop from the 97.6 billion won it earned in the same quarter last year. For a duopoly whose earnings track trading activity almost mechanically, simultaneous declines of this depth point to a market-wide contraction in Korean crypto turnover rather than a company-specific stumble.

Dunamu paired its earnings release with a reminder of its public-facing commitments, announcing that its youth support program has helped 4,122 young people restore credit standing and work toward financial independence over the past three years — the kind of disclosure that carries added weight for an industry still negotiating its regulatory standing in Seoul.

A Small Insurer’s Inflection Point

Between those poles, Lotte Insurance offered a modest but directionally significant result: second-quarter operating profit of 3.1 billion won and net profit of 1.3 billion won, returning the insurer to quarterly profitability. The absolute figures are small, but a swing back into the black matters for a mid-tier insurer that has been working through a difficult stretch.

What the Split Implies

Read together, the August 14 disclosures describe a sector where the safest franchises are currently the most profitable ones. Banks with entrenched corporate lending books converted the quarter into record income; platforms exposed to speculative trading volumes gave back most or all of their earnings power. For investors and policymakers watching Korea’s financial industry, the second quarter offers a clean natural experiment in which business models are holding up — and the answer, for now, is emphatic.
