Summary
Understand the differences between primary and secondary markets with Vanguard. Learn how these markets impact your investments and trading strategies.
Trading on the primary and secondary markets

Points to know
- Vanguard Brokerage offers CDs and bonds in both primary and secondary markets.
- Buying CDs and bonds in the primary market means you're transacting with the issuer of the security.
- Buying or selling CDs and bonds in the secondary market means you're transacting with other market participants.
What are primary & secondary markets?
Primary market
When you buy a CD (certificate of deposit) or bond on the primary market, you're buying a security that's just been created, commonly referred to as a "new-issue." It's like buying a new car. You're the original owner.
Proceeds from your purchase go to the issuer of the security, such as a bank for CDs and corporation or government agency for bonds.
Secondary market
When you buy or sell a CD or bond on the secondary market, you're transacting with another market participant, not the issuing company or agency. It's like buying a used car.
If you're selling a security, you get the proceeds; if you're buying one, proceeds go to the seller.

Open or transfer accounts
All brokered CDs will fluctuate in value between purchase date and maturity date. The original face amount of the purchase is not guaranteed if the position is sold prior to maturity. CDs are subject to availability.
CDs are guaranteed (within limits) as to principal and interest by the Federal Deposit Insurance Corporation, which is an agency of the federal government.
Investments in bonds are subject to interest rate risk, which is the chance bond prices overall will decline because of rising interest rates; credit risk, which is the chance a bond issuer will fail to pay interest and principal in a timely manner or that negative perceptions of the issuer's ability to make such payments will cause the price of that bond to decline; and inflation risk, which is the possibility that increases in the cost of living will reduce or eliminate the returns on a particular investment.
All investing is subject to risk, including the possible loss of the money you invest.
