Why Markets Shake the Day After FOMC

A lot of people in Korea wake up in the middle of the night to watch the US market the day after an FOMC meeting. Sometimes the Nasdaq drops 2% even when rates were held steady. Other times stocks fall even after a rate cut. Same meeting, but the market reacts differently every time. Let's unpack that — starting with the single sheet of paper called the dot plot.

What does the FOMC actually do?

FOMC stands for the Federal Open Market Committee. It's the top body that sets US monetary policy.

It meets eight times a year on a regular schedule — usually in January, March, May, July, September, November, and December — with occasional emergency meetings in between. Each meeting runs for two days, and the result drops on the afternoon of day two. In Korean time, that's roughly 3 a.m. the next morning.

The most important thing decided here is the federal funds rate. Because the US policy rate steers global capital flows, even a one-line announcement can shake Korean markets.

Three things come out after the meeting. First, the rate decision statement. Second, the press conference run by the chair right after. Third, the dot plot, which comes out once a quarter alongside the meeting. Markets combine all three to guess what comes next.

What is the dot plot?

The dot plot, in English, is just that — a grid chart with years on the horizontal axis and interest rate levels on the vertical axis. Dots are scattered across the grid.

Each dot is one FOMC member's personal forecast. About 19 officials place their dots at "where I think the rate should be by year-end." It's anonymous — no one tells you which dot belongs to whom.

What makes this matter is that markets look less at individual dots and more at the average and the spread. Dots clustering high means officials might see rates staying higher. Dots clustering low means cuts are coming faster.

The dot plot only comes out four times a year — at the March, June, September, and December meetings. So quarterly dot-plot meetings tend to shake markets harder than the regular ones.

Look at the March 2026 dot plot. The median year-end rate landed around 3.4%, the same number as the December 2025 plot. And yet the market still jolted. Why? The spread inside changed. Fewer dots in the "one more cut" zone, more dots in the "hold steady" zone. Median was the same, but the mood shifted.

Why does the market drop even when rates are held?

The most common question. Why does the market sometimes lose 3% on a day rates weren't even hiked?

The answer is one word: expectations. The market had already priced in a cut at the next meeting. Then the statement landed with a tone of "we're holding for a while longer." Same hold decision, but the tone was more hawkish than expected.

Hawkish means tilting toward keeping rates higher. Dovish is the opposite — tilting toward cuts. Even with the same decision, if the tone reads hawkish, markets get disappointed and sell stocks.

One word from the chair at the press conference can swing the day. If "now is a time for patience" shows up once, the market can lose 3% that day. That single phrase reads as "no cuts anytime soon."

So the same meeting and the same hold decision can send markets in opposite directions depending on one or two words from the chair.

How does a dot plot move markets?

A single dot plot moves more than just one or two assets. Here are the big arteries.

US short-term Treasury yields react fastest. The 2-year Treasury closely tracks the expected path of the policy rate, so a hawkish dot plot lifts it immediately. The 10-year follows, and then mortgage rates and corporate bond yields all get pulled along.

Next, stocks. A signal that rates will stay higher means future earnings get discounted more steeply to present value. That automatically shrinks stock prices. Growth and tech stocks — where most value sits in future earnings — get rattled the hardest.

Third, exchange rates. A signal that US rates stay higher boosts the dollar's appeal. Capital tilts further toward dollars, so the dollar strengthens against other currencies. The dollar-won rate often climbs as a result.

And last, Korean markets. When the US market falls, Korean markets typically follow the next morning. Foreign capital tends to leave alongside.

So how should you read an FOMC meeting?

Three things will do.

First, watch the tone more than the headline. If the rate decision is the first news, the chair's word choice is the second — and markets react harder to the second.

Second, dot-plot meetings shake more than regular ones. Mark the March, June, September, and December meetings on your calendar.

Third, don't draw conclusions from the first 30 minutes. Algorithms react first and push hard one way, only for things to revert the next day. Wait until after the press conference and the US closing print to see how the day actually settled.

The FOMC is just a meeting in the US, but it's a meeting that reaches Korean accounts too. If you build a habit of summarizing each dot plot's signal in a single line, your read of the broader market flow gets a lot sharper.
