For millions of pensioners, the State Pension has suddenly become part of a much bigger political argument.
The immediate message is reassuring.
The triple lock is safe for the rest of the current Parliament.
But that does not necessarily mean it will still exist in its present form after the next general election.
Andy Burnham has opened the door to a review of the triple lock as part of Labour's next manifesto, meaning that any change would come after the election expected by 2029 rather than during the current Parliament.
That distinction matters.
The triple lock currently means that the basic and new State Pension rises each April by whichever is highest of average earnings growth, inflation or 2.5%.
It has become one of the most politically sensitive promises in British politics because it directly affects millions of older people.
The Government's own guidance confirms that the triple lock remains the mechanism for increasing the State Pension.
What happens next April?
For the immediate future, pensioners should not be expecting the triple lock to disappear.
The latest earnings figures suggest that earnings growth is likely to determine the April 2027 increase, with the figure currently around 3.9%.
The Institute for Fiscal Studies says it is very likely that earnings growth will determine next year's increase.
That would mean the full new State Pension rising from its current £241.30 a week to roughly £250.70.
That is an increase of around £9.40 a week, or almost £490 over a full year.
The final figure will depend on the official calculation used by the Government.
So the immediate issue is not whether pensioners will receive their April increase.
They will.
The bigger question is what happens afterwards.
Why has the triple lock become such a problem?
The triple lock was introduced in 2011.
It was designed to prevent the State Pension falling behind either wages or prices and to guarantee a minimum annual increase of 2.5%.
It has worked.
The IFS says the policy has materially increased the generosity of the State Pension since it was introduced.
But that success comes with a cost.
State pension spending is now enormous, and the triple lock makes future spending more difficult for governments to predict because the increase depends on whichever of three measures happens to be highest.
If wages rise rapidly, pensions rise rapidly.
If inflation rises rapidly, pensions rise rapidly.
And even if both are low, there is still the 2.5% minimum.
The IFS argues that the triple lock creates high and uncertain future costs for government.
So why bring it up now?
The answer is social care.
Burnham has made reform of adult social care one of his major political ambitions.
He has said that his full plans will not be implemented during the current Parliament and that voters would be asked to consider the programme at the next general election.
That creates a potential funding problem.
A much more generous social care system could require substantial additional public spending.
And that is where the triple lock has entered the discussion.
Burnham has not announced that the triple lock will be abolished.
But reports from Labour conference suggest that reforming it could be considered as part of the next manifesto.
That means pensioners are being given something of a warning without facing an immediate cut.
What could replace it?
There are several possibilities.
One would be to retain the triple lock exactly as it is.
Another would be a double lock, removing the 2.5% minimum and increasing pensions by whichever is higher of earnings or inflation.
Another possibility would be to link the State Pension permanently to earnings.
There could also be a different formula altogether.
The important point is that none of these has been announced as the future policy.
The IFS has examined alternatives and has argued that a more predictable system could be designed without the triple lock.
The tax problem is becoming more interesting
There is another issue which could make the argument particularly complicated.
The personal tax allowance has been frozen while the State Pension has continued to rise.
That means a pensioner receiving the full State Pension and having other taxable income could increasingly find themselves paying income tax.
The Government has already said that someone receiving only the full new State Pension should not be brought into income tax simply because of the forthcoming increase.
But the interaction between frozen tax thresholds and rising pensions remains an important issue for people with other income.
This creates several possible ways of changing the overall system without simply announcing that pensioners will receive smaller increases.
The political problem
This is where the triple lock becomes a political hot potato.
There are millions of pensioners, and they vote.
But there are also millions of younger taxpayers who will ultimately have to finance the public spending commitments of an ageing population.
The argument is therefore not simply about whether pensioners deserve protection.
It is about how Britain divides its limited public resources between different generations and different priorities.
The Government already faces pressure from the NHS, social care, defence, local government, housing and debt interest.
The September 2026 UK fiscal outlook also warns that rising borrowing costs are reducing the Government's room for manoeuvre.
That makes the long-term cost of the State Pension impossible for any government to ignore.
But there is another side to the argument
The State Pension remains the basic foundation of retirement income for millions of people.
Not everyone has a large private pension, investments or substantial savings.
For people who have spent much of their working lives on modest incomes, the State Pension can be their main source of financial security.
Removing the triple lock would therefore not affect everyone in the same way.
A change which saved the Treasury money could also mean that some pensioners saw their income rise more slowly during periods of increasing wages or prices.
That is why the debate is so politically sensitive.
So what should pensioners expect?
For now, there is no reason to change household budgets on the assumption that the triple lock is about to disappear.
The April 2027 increase is still being calculated under the existing system.
The Government remains committed to the triple lock for the current Parliament.
But after the next election, the position could be different.
What Burnham has effectively done is move the argument from "Will the triple lock be abolished now?" to a much longer-term question:
"Can Britain afford to keep the triple lock indefinitely?"
That is a much more difficult question.
And it is one which will increasingly involve not just pensioners, but their children and grandchildren, because today's pension promises become tomorrow's public spending commitments.
For now, the triple lock remains.
But pensioners should probably regard 2029 as the date when the argument could become much more serious.
