High-Yield Savings in Korean (2026): Term & Rates
What "High-Yield Savings Account" Means in Korean
The closest translation is 고금리 예금 (go-geumni yegeum), literally "high-interest deposit" — you may also see 고수익 저축예금 ("high-return savings deposit"). Either phrase works on a bank form or in conversation.
There is no single 1:1 product in Korea. The role a US high-yield savings account (HYSA) plays is split into two things: a 파킹통장 (parking account) you can withdraw from anytime, and a 정기예금 (fixed-term deposit) locked for a set period like 12 months.
So decide what you actually want. If you just need the words, use 고금리 예금. If you want a real account you can open in Korea, you are choosing between a 파킹통장 and a 정기예금.
US High-Yield Accounts vs. Korean Equivalents
A high-yield account simply pays meaningfully above the national average, usually through online banks, and quotes an APY that reflects compounding. The trade-offs — variable rates, transfer limits, and deposit insurance — differ by country.
| Feature | US HYSA | Korean 파킹통장 | Korean 정기예금 |
|---|---|---|---|
| Typical rate (2026)* | ~3.5–5% APY | ~1.6–3.7% | ~3.5–3.7% |
| Access to cash | Anytime | Anytime | Locked for term |
| Deposit insurance | FDIC $250,000 | KDIC (verify cap) | KDIC (verify cap) |
| Tax on interest | Taxed as income | 15.4% withheld | 15.4% withheld |
*As of 2026, subject to change — confirm on the official bank page. Kakao Bank's Safebox parking account pays 1.60% (pre-tax, Aug 20, 2026) on balances up to ₩100 million. Headline promo rates like Shinhan's 9dan savings (up to 9%), Woori's up to 8.29%, and Toss Bank's 10% are installment savings (적금) with small monthly caps, not lump-sum parking accounts.
If you are moving cash between Korea and a US bank, compare after-tax returns: Korea withholds 15.4% on interest at source, while a US HYSA leaves tax to your annual filing. Match the product to your access needs first, and the rate second.

Worked example: park ₩10,000,000 in Kakao Safebox at 1.60% for 12 months. Simple interest is ₩160,000 pre-tax; daily compounding nudges it to about ₩161,290. After the 15.4% withholding, you keep roughly ₩136,400. A 1 percentage-point higher rate (2.60%) would pay ₩260,000 pre-tax — ₩100,000 more on the same balance.
Common mistake: chasing a "9%" headline. Shinhan's 9% caps deposits at ₩300,000/month, so 12 months of deposits earn about ₩175,500 pre-tax — not ₩324,000. High rates on tiny caps produce small won amounts.
Before opening, run this checklist:
- Confirm today's rate on the official page — rates move with central-bank policy.
- Check the monthly deposit cap and whether the rate is promotional.
- Subtract the 15.4% tax and factor in inflation for your real return.
- Verify current KDIC (Korea) or FDIC ($250,000, US) coverage limits.
To open one: in the US, apply online with an online bank; in Korea, you typically need residency, a Korean ID or ARC, and a linked checking account (Kakao Safebox allows one per linked account).

Common Questions
How do you say "high-yield savings account" in Korean?
The usual translation is 고금리 예금 (go-geumni yegeum, "high-interest deposit") or 고수익 저축예금. Korea has no single equivalent product, so day-to-day you'd choose a 파킹통장 (parking account) or 정기예금 (fixed-term deposit).
Do Korean savings accounts really pay 8–10%?
Those headline rates are promotional installment savings (적금) with monthly deposit caps, often ₩300,000, for a fixed term. Everyday parking accounts pay far less — Kakao Safebox is 1.60% as of 2026, subject to change.
Is interest on a Korean savings account taxed?
Yes. As of 2026, interest is subject to 15.4% withholding at source (원천징수), so quoted rates are pre-tax. This is informational only; confirm current rules on an official source and consult a tax professional.
