The European Central Bank has raised interest rates again, and that could be an important warning for Britain.
The ECB increased its key deposit rate by 0.25 percentage points to 2.5% last week as inflation across the eurozone moved higher. The main concern is the renewed rise in energy prices, which is feeding directly into inflation.
That matters in Britain too. The Bank of England has kept Bank Rate at 3.75%, but the latest developments have made the prospect of further rate cuts considerably less certain. The Bank's next decision is due on 17 September.
Energy prices complicate the picture
The difficulty for central banks is that higher oil and gas prices are not caused by consumers borrowing too much or spending too freely.
They are largely an external shock.
But energy is used throughout the economy. Higher fuel costs feed into transport, manufacturing, heating and eventually the prices charged by businesses. There is also a risk that workers seek higher wages to compensate for increased living costs.
Central banks therefore have to consider whether an energy shock that might initially be temporary begins to create more persistent inflation.
That is one reason the ECB decided to raise rates rather than simply look through the latest increase in inflation.
Britain faces a different problem
The UK economy, however, is showing signs of weakness. Today's ONS figures put unemployment at 4.9%, while the number of payrolled employees has fallen by around 101,000 over the year. Vacancies have also slipped to 702,000.
The employment rate is 75.1%, while economic inactivity among people aged 16 to 64 is 20.9%.
This gives the Bank of England a difficult balancing act.
Higher interest rates can help suppress inflation, but they can also weaken an already soft labour market by making mortgages, business borrowing and investment more expensive.
So could UK rates actually rise?
For the immediate decision, a rise is not expected to be the most likely outcome. The Bank can afford to wait and see whether the latest energy-driven inflation increase proves temporary.
But the ECB decision is significant because it demonstrates how quickly the outlook can change.
Only recently the debate was largely about when interest rates might fall further.
The question is now becoming whether central banks may have to keep rates higher for longer, or even raise them again, if energy prices remain elevated.
Markets are already putting greater weight on the possibility of a UK rate increase later in the year.
For mortgage borrowers, businesses and anyone relying on savings income, this is an important change in the interest-rate outlook.
The Bank of England does not have the power to make oil cheaper. What it can do is try to stop an energy-price shock becoming a broader inflation problem.
That leaves Britain facing an awkward combination: higher energy costs, a weakening jobs market and interest rates that may not fall as quickly as many had expected.
The ECB's decision does not mean the Bank of England will automatically follow.
But it is a reminder that the next move in UK interest rates is no longer guaranteed to be down.
