Bond Korean reverses everyday price intuition

A market article says:

국채 10년물 수익률이 상승했다. 채권 가격은 하락했다.

A learner may wonder: if yield went up, is that good or bad? Bond-market language often discusses yield, price, maturity, issuance, credit rating, and spread. The grammar is not hard; the relationships are.

The key principle is:

Bond-market Korean is relationship literacy.

This article teaches language reading, not investment advice.

채권

채권

bond/debt security; also claim/right to receive payment in legal contexts, depending domain.

Bond-market context:

회사채 corporate bond

국채 government bond

채권시장 bond market

채권 가격 bond price

Learner action: in finance articles, 채권 usually means bond. In legal context, it may mean creditor claim. Domain matters.

국채

Learner action: identify issuer and maturity.

수익률

수익률

yield/return rate.

Bond news often uses:

국채 수익률 government bond yield

수익률 상승 yield rise

수익률 하락 yield fall

Bond yields and bond prices generally move inversely.

Learner action: if 수익률 rises, bond price may fall. Do not read it as generic “profit went up.”

금리

금리

interest rate.

In bond-market articles, 금리 may refer to:

• market interest rates,
• policy rates,
• yields,
• loan rates,
• benchmark rates.

Related:

기준금리 policy/base rate

시장금리 market rate

장기금리 long-term rate

Learner action: check whether 금리 is policy rate, bond yield, or loan rate.

만기

만기

maturity.

Related:

만기일 maturity date

만기 도래 maturity arrives/comes due

만기 3년 3-year maturity

만기수익률 yield to maturity

Learner action: maturity tells time horizon of repayment.

신용등급

신용등급

credit rating/credit grade.

Bond context:

회사채 신용등급 corporate bond credit rating

등급 하향 rating downgrade

등급 상향 rating upgrade

투자등급 investment grade

투기등급 speculative grade

Learner action: credit rating affects perceived default risk and yield.

스프레드

스프레드

spread.

In bond markets, spread may mean the difference between yields.

Examples:

회사채 스프레드 확대 corporate bond spread widening

국채 대비 스프레드 spread relative to government bonds

Learner action: widening spread often signals higher risk premium or market stress, depending context.

발행

발행

issuance.

Bond context:

국채 발행 government bond issuance

회사채 발행 corporate bond issuance

발행금리 issuance interest rate/yield

발행규모 issuance amount

Learner action: 발행 is supply/event language.

입찰

auction/bidding.

Bond context:

국채 입찰 government bond auction

낙찰금리 winning/accepted yield

응찰률 bid-to-cover or participation ratio, context-dependent

Learner action: 입찰 tells how bonds are sold/allocated.

• market news,
• central-bank coverage,

Bond-market reading workflow

When reading Korean bond-market news:

1. Identify issuer: government, company, bank?
2. Identify instrument: 국채, 회사채, 채권.
3. Identify maturity: 3년물, 10년물, 만기.
4. Identify metric: yield, price, spread, rating.
5. Mark direction: 상승, 하락, 확대, 축소.
6. Remember price-yield relationship.
7. Identify cause framing: 금리, 물가, 중앙은행, credit.
8. Check issuance/auction language.
9. Separate market fact from analysis.
10. Do not treat language comprehension as investment advice.

Bond relation table

Bond Korean is easiest when the financial relationships are explicit.

These are reading relationships, not investment rules.

Instrument and metric table

Never read 수익률 as generic “profit rate” without bond context.

Domain ambiguity warning

채권 can mean a bond in finance or a claim/creditor right in legal contexts. If nearby words include 국채, 회사채, 수익률, 만기, or 스프레드, finance is likely. If nearby words include 채무자, 변제, 권리, or 담보, legal-creditor language may be active.

A strong tool for this article would connect bond terms visually.

Suggested functions:

1. Issuer/maturity detector.
2. Yield/price/spread classifier.
3. Direction arrow.
4. Price-yield inverse warning.
5. Credit-rating popover.
6. Issuance/auction label.
7. Plain-language market summary.

Final rule

Bond-market Korean is about relationships.

국채 and 채권 name instruments. 만기 names time. 수익률 and 금리 name yield/rate. 스프레드 names difference. 신용등급 names risk. 발행 and 입찰 name supply process.

If you read 수익률 like ordinary profit, you will misunderstand the market sentence.
