Bank of England and Bank of JapanBoE

BoE and BoJ in plain words
At the Bank of England, interest-rate decisions are made by the Monetary Policy Committee (MPC).1
The Bank of Japan is Japan's central bank, and its Policy Board sets the direction of monetary policy at Monetary Policy Meetings (MPMs).2
Both are Central Bank committees: they set a policy Interest Rate and can also buy or sell bonds.
How to follow BoE and BoJ decisions
Know the calendar
Mark the MPC's eight announcements a year — about one every six weeks.1
Know the decision makers
The MPC has nine individual members; the BoJ decides at Monetary Policy Meetings (MPMs) of its Policy Board.2
Read the mandate
Know the BoJ's legal mandate: issuing banknotes and managing currency and monetary control.3
Compare with forecasts
Markets react to surprises, not to expected moves.
Read the vote split
A split MPC vote can hint at the next move.
Think about lags
Rate changes take roughly 18 to 24 months to work through fully, so central banks act on forecasts.1
Worked examples
Example 1 — Surprise hike
+100 pipsA hypothetical MPC raises rates by 0.25% when markets expected no change; GBP/USD moves from 1.2500 to 1.2600.
| Rate change | +0.25% |
| GBP/USD before | 1.2500 |
| After | 1.2600 |
The MPC makes the call, so an unexpected decision moves the pound.1
Example 2 — Vote split
Close callA hypothetical MPC votes 5–4 to hold.
| Members | 9 |
| Hold | 5 |
| Hike | 4 |
With nine individual members, a 5–4 split signals a close call and markets may price a hike at the next meeting.1
Example 3 — BoJ easing
Yen −7%A hypothetical BoJ keeps rates low while others hike; USD/JPY rises from 140 to 150.
| USD/JPY before | 140 |
| After | 150 |
| Yen | Weaker |
These decisions come from the Policy Board's meetings, and a wide interest-rate gap often weakens the yen.2
