Interest rate decisions are major events for FX traders, but the decision itself is only part of the story. Markets look ahead, so an expected rate change may already be reflected in the price before the meeting.
This is why the statement and press conference can have a bigger impact. In September 2026, both the Fed and BOJ raised rates as expected, but the yen still weakened and USDJPY moved higher. The key was what each central bank said about future interest rates.
What Is a Central Bank Statement and Why Does It Matter?
When a central bank announces an interest rate decision, it usually releases a statement explaining the decision and giving its latest view of the economy. The statement may discuss inflation, economic growth, employment and other risks. For FX traders, one of the most important parts is what the wording suggests about future interest rates.
The central bank governor or chair will also usually hold a press conference after the announcement. Traders therefore follow the rate decision, statement, economic forecasts, voting result and press conference together. All of these can provide clues about where interest rates could go next.
Two common words used to describe these messages are hawkish and dovish:
- Hawkish means the central bank is more concerned about inflation and more willing to keep interest rates high or raise them further. This can support the currency.
- Dovish means the central bank is more concerned about weak economic growth or believes inflation is becoming less of a problem. This can increase expectations for lower interest rates and may weaken the currency.
The important point is that hawkish and dovish are also about expectations. A central bank can sound hawkish but still see its currency fall if traders had expected an even stronger message.
Markets do not wait until the day of the meeting to form these expectations. Traders follow inflation, employment, wages, economic growth and comments from central bank officials in the weeks before the decision. If a rate increase becomes widely expected, traders can position for it beforehand, meaning the actual announcement may contain little new information.
What Happened at the Fed and BOJ Meetings?
Ahead of the September meetings, both rate increases were widely expected. The Fed raised its target range by 0.25 percentage points to 3.75%–4.00%, while two days later the BOJ increased its policy rate from 1.00% to 1.25%.
The Fed's rate increase was not a major surprise, but the message around future policy remained relatively hawkish. The Fed said economic activity continued to expand at a solid pace while inflation remained elevated. Its updated projections also showed higher expected interest rates, with the median forecast for the federal funds rate at the end of 2026 rising to 4.1% from 3.8% in June. Most policymakers expected at least one additional increase during 2026.
This suggested that the September increase might not be the Fed's final move. If traders believe US interest rates could stay high or rise further, US assets can remain attractive, which can support demand for the dollar.
The BOJ delivered the same size increase, but the market reaction was very different. Higher Japanese interest rates would normally support the yen, but the increase from 1.00% to 1.25% was already expected. Traders therefore focused on what the BOJ said about future increases.
One important detail was the 7–2 vote, with two policymakers preferring to leave rates unchanged. The BOJ also kept the possibility of further increases open without giving a clear timetable. For traders who had hoped for a stronger signal that another increase could come soon, the overall message was less hawkish than expected.
The result was yen weakness and a higher USDJPY. Traders had already prepared for the BOJ rate increase, so the decision itself gave them little new reason to buy the yen. At the same time, the Fed was giving the market more reason to believe US rates could remain high.
Why Expectations Can Matter More Than the Rate Decision
A rate increase does not automatically make a currency rise, just as a rate cut does not automatically make it fall. The market is constantly comparing what happens with what was expected to happen.
If traders expect the BOJ to raise rates and strongly suggest that another increase is coming, simply delivering the expected increase may not be enough to strengthen the yen. If the statement is more cautious than expected, the yen can actually fall.
Positioning before the meeting can make this reaction stronger. If many traders have already bought the yen in preparation for a BOJ rate increase, there may be fewer buyers left when the decision is finally announced. A disappointing statement can then encourage those traders to take profits or close their positions, adding to the yen's decline. This is sometimes described as "buy the rumour, sell the fact."
Why Central Banks Give Guidance but Avoid Promises
Central banks know their words can move markets, so they give some guidance about where interest rates may be heading. However, they avoid making firm promises because economic conditions can change.
This is why they often say future decisions will be "data dependent." For traders, small changes in the statement can give clues about whether the central bank is becoming more hawkish or dovish. The vote also matters, as a divided decision can suggest less support for further changes. This was one reason the BOJ's 7–2 vote attracted attention.
Volatility First, Trend Later
Central bank announcements can cause fast price moves because traders receive a lot of information at once. The market may first react to the rate decision, then change direction as traders read the statement and listen to the press conference.
Once the initial volatility settles, a clearer trend may develop as traders adjust their expectations for future interest rates. Traders can try to trade the first move, but waiting can reduce the risk of sudden reversals and make the direction easier to understand.
How to Trade Central Bank Statements
Trading these events becomes easier when the focus is on expectations rather than trying to predict every short-term move. A simple process is to separate the event into three stages:
- Before the meeting: Understand whether a rate change is expected, what traders expect the central bank to say about future rates, and whether the currency has already moved strongly in anticipation.
- During the announcement: Watch the rate decision, statement, vote and press conference. Expect volatility and remember that the first move may not last.
- After the initial reaction: Look at how the market has interpreted the overall message. If volatility begins to settle and price starts moving consistently in one direction, there may still be an opportunity to follow the developing trend.
Risk management is especially important around central bank meetings. Spreads can widen, stop-loss orders can suffer slippage and the first move can quickly reverse. Reducing position size or waiting for calmer conditions can make the trade easier to manage.
The aim does not have to be catching the very first move. Waiting for the market to process the statement and press conference can sometimes provide a clearer setup, particularly when the new central bank message changes expectations for the coming months.
Focus on What Changes Expectations
Central bank meetings are easier to understand when you look beyond the rate decision. The statement, vote and press conference can give clues about what may happen next, which is often more important for currencies.
In September, both the Fed and BOJ raised rates as expected, but the Fed gave a stronger signal that rates could rise again, while the BOJ was less clear about future increases. This helped USDJPY move higher and showed why understanding what the market already expects is so important.
