The return to health of the UK's state-aid banks Lloyds and RBS will be tested next week, alongside other blue-chip results from BT and BP.
Royal Bank of Scotland's quarterly figures on Friday will be dominated by attention on the outcome of a Government-commissioned report into whether the bank's "bad" assets should be hived off.
The study by investment bank Rothschild has advised Chancellor George Osborne on the merits and pitfalls of separating operations such as Ulster Bank and £40 billion of non-core loans in order to accelerate the privatisation of the remaining good parts.
Any such move could also result in the accelerated sale of its American retail bank Citizens, valued at around £8 billion.
Friday's results will be the first for new chief executive Ross McEwan, after he replaced ousted boss Stephen Hester this month.
The New Zealander, who previously ran RBS's retail banking arm, has promised to boost lending to support the economy and put customers at the heart of its strategy.
According to UBS, the 80% state-owned bank is expected to report flat profits of £1.1 billion from core operations in the three months to the end of September, helped by Britain's recovering economy.
Despite progress on repairing its balance sheet, Investec analyst Ian Gordon warned RBS is still battling a " dangerous cocktail of legal, political and regulatory obstacles".
However, fears over a damaging carve-up have largely been offset by optimism over more non-core asset sales - including its agreement to sell more than 300 surplus branches to investors including the Church of England.
Britain's buoyant housing market has also helped underpin the stock, with Mr Gordon predicting a "meaningful pick-up" in mortgage lending during the quarter.
The British Bankers' Association recently reported the strongest month for mortgage approvals since 2009.
RBS joins most of the UK's major lenders in backing the latest phase of the Government's Help to Buy scheme, which guarantees mortgages to allow people to buy a home with a 5% deposit.
Analysts at Credit Suisse predict a "weak quarter" by the bank. "We expect cost reduction will not have kept up with the pace of revenue decrease," they said.
Taxpayer-backed Lloyds Banking Group and rival Barclays will both update the City on their third quarter performance amid a period of upheaval for both businesses.
The trading update for Lloyds on Tuesday will be the first since the Treasury began the process of returning its stake in the bank to the private sector, selling a 6% chunk for £3.2 billion to institutional investors last month.
Official figures showed profit on the sale provided a half-billion pound boost to the public accounts.
The Lloyds group, which also includes Halifax Bank of Scotland (HBOS), swung out of the red with half-year profits of £2.1 billion earlier this year.
It had to be rescued by the Government during the financial crisis after swallowing up troubled HBOS and later took a multi-billion pound hit from the scandal of payment protection insurance (PPI) mis-selling.
But Lloyds, now 33% state-owned, looks to be returning to health as it continues to dispose of non-core assets including Australian insurance and corporate lending businesses.
It has also spun off more than 600 branches under the revived TSB brand, with plans to float the business on the stock market next year.
Credit Suisse analysts expect third quarter pre-tax profits of £793 million, with £300 million restructuring charges and £300 million provision for customer redress following PPI and other mis-selling claims.
Last year Lloyds recorded a £144 million pre-tax loss for the period.
Meanwhile Barclays received strong support earlier this month for a £5.8 billion rights issue offered as part of a plan to meet the City regulator's demand that it plug a £12.8 billion hole in its finances.
The issue saw 95% of shares taken up, with the remainder offered in the wider market by underwriters.
Boss Antony Jenkins is leading a crusade to overhaul the culture at the bank, with a major restructuring in the wake of last year's Libor rate-rigging scandal.
However, the bank's reputation has taken further blows after it revealed it was facing a £50 million fine over claims it acted recklessly in its multi-billion pound bail-outs from Qatar in 2008.
Hargreaves Lansdown analyst Keith Bowman said Barclays was likely to suffer from uncertainty over US financial policy that has hit other banks with significant investment arms, though better conditions for its retail bank could offset this.
BT unveils second quarter results on Thursday amid concerns that it has overestimated the size of the market for its TV sports channels as it vies with BSkyB over Premier League football coverage.
Analysts at UBS have downgraded shares in the telecoms giant, judging that it may struggle to make good its major investment in the project.
BT has paid £738 million for the rights to show 38 top-flight football games a season for three years.
It said earlier this year that it expected earnings in the second quarter to the end of September to take a £100 million hit as it starts to recognise programme content costs.
But BSkyB has shrugged off the competition, announcing earlier this month that record numbers tuned in to the start of the football season - with an average audience of 1.55 million compared with 1.29 million last year.
Figures show BT has achieved average audiences of 588,000 for Premier League matches, less than the 641,000 average achieved last season by ESPN.
But it points out that it has a higher audience share, averaging 4.95% of around nine million viewers watching TV at lunchtime when its games are shown, compared to ESPN's 2.8% of a total teatime audience that was twice the size.
The Newcastle-Liverpool clash last weekend was its strongest-rated yet, achieving a peak of 832,000, and an average audience of 724,000.
BT also argues that high numbers of people watching via tablet computers are not counted in BARB viewing data.
Its sports TV offering is bundled in free for broadband customers, while the addition of a large chunk of Virgin Media subscribers took the total equipped to watch the channels to three million by the middle of August.
Analysts at Nomura said the impact of the investment should have helped it cut the number of consumer lines being lost to 85,000 and added 100,000 broadband lines, up from 81,000 for the same period last year.
On average, City experts are pencilling in a 0.8% drop in overall revenues for the quarter to £4.44 billion and adjusted profit before tax to fall 9% to £555 million.
Oil giant BP posts third quarter figures on Tuesday in the wake of a legal victory for the group to limit compensation payouts for the 2010 Gulf of Mexico oil spill.
A US federal appeals court said the terms of a compensation agreement struck with BP last year should be reviewed to help stem bogus or inflated claims for damage by businesses from the disaster, when an explosion on its Deepwater Horizon oil platform killed 11 men and sparked the worst spill in US history.
It was seen as a crucial success for the group as its vast trust fund to cover the bill runs dry.
BP warned earlier this year that its escalating compensation bill would see the last 300 million US dollars (£185 million) in the trust fully used up in the third quarter, leaving additional amounts to be ''charged to the income statement''.
It has already set aside 9.6 billion US dollars (£5.9 billion) to cover the cost of claims, but said recently the group had paid out more than a billion dollars (£617 million) of phony claims.
A US court injunction has now been approved against payments made to businesses that have not suffered actual loss from the spill and investors will be keen for any estimation of the cost savings for the group.
Third quarter figures are expected to show profits coming under pressure, with analysts expecting a 37% plunge year-on-year to 3.17 billion dollars (£2 billion).
The group is coming up against tough comparisons after seeing profits boosted by sharply higher refining margins a year earlier.
But the quarterly profit result will mark an improvement on the 2.7 billion dollars (£1.7 billion) recorded the previous three months thanks in part to an 8% rise in oil prices.
BP may look to assure over its plans to invest in exploration as it seeks to get the business back on track following a difficult past few years.
It is stepping up capital spending to between 24 billion (£14.8 billion) and 25 billion dollars (£15.4 billion) this year - of which 3 billion dollars is going towards exploration - and has already said it expects to drill more wells in 2013 than in the last three years combined.
