Bond selloff hits F & I Funds; stocks mostly steady

Thursday was mostly a bond story: Treasury yields jumped to multi-decade highs as hot economic data, oil prices and rising odds of another Fed rate hike pushed rates up. That hurt the F Fund most and weighed on international stocks, while large U.S. stocks ended nearly flat.

One-day change by fund
FundPrice1 day
G Fund$20.2399+0.01%
F Fund$20.3991-0.49%
C Fund$124.2915-0.02%
S Fund$113.6999-0.14%
I Fund$64.8394-0.82%

F Fund

-0.49%

What happened: The F Fund fell 0.49% for the day and is down 2.15% for the month.

Why it moved: Treasury yields jumped, with the 30-year reaching its highest level since 2004. Since bond prices fall when yields rise, that pressured the F Fund.

What it could mean: Bond funds can stay under pressure while yields climb, though bond prices and yields have historically moved in cycles.

Full briefing: one of these for every fund, plus the L Funds.

TSP 101

The G Fund's rate is set once a month by the U.S. Treasury, based on the average yield of about 202 Treasury securities. That's why its share price inches up almost every day instead of swinging with the markets.

Questions

Do you need my TSP login?

No, never. We don't ask for your tsp.gov username, password or account number, and we never connect to your account. The briefing uses the share prices TSP publishes publicly.

Is this investment advice?

No. Reveille Brief explains what happened in the markets and what it could mean in general terms. We never tell you to buy, sell or move money between funds. Those decisions are yours.

Are you part of the TSP or the government?

No. Reveille Brief is independent. We're not affiliated with the Federal Retirement Thrift Investment Board, the Thrift Savings Plan, or the U.S. government.

Where do the numbers come from?

Fund prices come from the official daily share prices published on tsp.gov. The explanations draw on reputable financial news and official sources, which we link in every briefing.

Who writes it?

Each briefing is researched and drafted with the help of AI, checked automatically for advice language, and reviewed by a person before it's sent.

When does it arrive?

Every weekday morning after a trading day, covering the previous day's market close. No email on weekends or market holidays.
