He's at it again this morning, letting it be known that he'll use this week's trip to the US to, among many other things, tell Wall Street banks to come clean about the mortgage horrors on their books.
Well so they should, but they don't need a British Prime Minister to tell them.
Much more to the point, he apparently used his breakfast with British bank bosses yesterday (for it was he, not Chancellor Alistair Darling as we wrote on Monday, Alistair has his turn next week) to suggest that the Bank of England might accept some of their mortgage-backed securities as collateral for some of the hard cash (£50bn in all) it is threatening to pump into the markets.
In turn, he wants the banks to lend to first-time house buyers, people coming off fixed rate deals (there will be thousands of such Northern Rock customers) and go easy on repossessions.
Because the credit crunch isn't about economics any more, it's about politics.
Banks losing people's houses is one thing, banks losing votes is far more serious.
Sir Terry is upbeat at Tesco
The sceptics have been bad-mouthing Tesco for the best part of a year now, driving down its shares on fears that two decades of relentless growth in sales and profits is coming to an end.
CEO Sir Terry Leahy isn't having any of it, delivering his expected £2.8bn of profits yesterday and rebutting speculation that its Fresh & Easy convenience chain in California is stalling.
Fresh & Easy is ahead of target says Leahy, with sales per square foot ahead of average US levels, more than $20 per square foot in the best stores.
What he didn't tell us was precisely how many stores are performing this well. Tesco won't report US sales figures until September.
This could be Tesco buying time of course, although it says it is bringing forward the opening of another distribution centre in northern California, so it looks as though it's in for the long haul.
And talking of long hauls, it generated £700m of profits (25% of the total) abroad, where it is strong in Eastern Europe and Thailand.
It's also stepping up its efforts in Turkey and China, two hugely populous markets.
With new store sites harder to find in the UK (and highly contentious when it does open a new one) Tesco's strategy of expanding abroad looks the right one.
It will get bigger in the UK too, of course, but more through its online operations (it's moving into the music download market) and financial services.
UK retailers cut iPhone prices
O2 and Carphone Warehouse are cutting the price of the "entry level" 8GB iPhone by a chunky £100 to £169, suggesting either that sales are stalling or that Apple is planning to introduce a 3G phone some time soon.
It's probably a bit of both.
The 16GB handset is staying at a rather daunting £329 for now.
iPhones are ludicrously expensive in the UK, you can pick up an 8GB one for €99 (£79.50) in Germany, and it seems as though there aren't enough dedicated Apple enthusiasts around to keep sales motoring.
The story for UK retailers with a recession looming is price, price and price again (as Terry Leahy observed yesterday).
It seems that not even Apple can buck the trend.
A Diamond for Boris?
Back to politics and we learn that London Mayor favourite Boris Johnson ('Al' to his friends) has signed up Barclays Capital boss Bob Diamond as an adviser.
Diamond is a rather bumptious American (apparently he got up the noses of the regulators at last weekend's International Monetary Fund pow-wow) who trousered £21m in salary and bonuses last year, way ahead of Barclays CEO John Varley.
Quite what Diamond will bring to Boris's party is unclear (apart from the ability to stand his round of course). Fundraising for the Mayor's Fund designed to tackle youth crime and social issues is apparently on the agenda.
Earlier this year, Diamond announced he would be spending most of his time in the US, to pick up bargains in the wake of the credit crunch.
Still, Bob's certainly got a good contact book. And at least he's not being paid.
Oil powers London market rally
"It's an ill wind" as we've often remarked here. London shares powered ahead 75 points yesterday and rose again this morning, mostly thanks to oil hitting a new peak of $114 a barrel.
This isn't good news for anyone, apart from oil giants BP and Shell whose shares drove the market up.
These days, the London FTSE100 is mainly comprised of multinationals, so there are times when it gives no guidance at all to events in the dear old UK.
But the broader-based FT All Share index also rose yesterday. Does someone know something we don't?
