The Chancellor isn't expected to budge on cuts or raising tax, save for some tinkering round the edges and a rethink on fuel duty.
In fact today's news that inflation is rising even faster, now reaching 4.4% (or 5.5% on the RPI measure), limits Osborne's room for manoeuvre because any retreat from his hard stance might add to pressure on the the Bank of England to raise interest rates.
Due to go up by inflation plus a penny, the fuel duty escalator.
Will he forget about the 1p, or forgo the whole increase, or postpone it, staggering the hike over the rest of the year?
Duty on booze.
Will Osborne bottle on the other duty escalator?
A rise of inflation + 2% is pencilled in, which might mean 3p on a pint, or even more once suppliers add their mark-up.
One populist measure could be to forgo some of the increase.
He is likely to announce a lower rate of duty for weak beers and a higher rate for strong beers.
Lots on pensions.
More detail expected on a £140 flat-rate pension, planned for 2015.
Reaction to Hutton Report on public sector pensions.
Possible mention of giving pension savers early access to their money.
At new tax-free savings scheme has been promised for the autumn. More information is expected.

The Office for Tax Simplification said it might be a good idea, so expect a study.
The OTS also wanted a review of inheritance tax.
Air Passenger Duty
There have been rumours of a freeze, to soften the impact of fuel surcharges on holidaymakers.
And maybe there'll be an update on per flight duty to replace Air Passenger Duty (promised in the coalition agreement).
Crackdown on cheap CDs
He could close the VAT loophole for CDs, DVDs costing under £18 from the Channel Islands. Costs £130m a year.

*Personal allowance rising to £7,475 from £6,475, to £10,000 in 2015-16
*Corporation tax cut to 27% from 28%, small profits rate to 20% from 21%
*£50,000 annual limit on pension contributions.
*5% stamp duty for £1m homes
He might want to gloss over:
