You really think that is a fair comparison?

As I recall there were two concurrent avenues for realisation of redress from the failed banks.

One was that the bank did indeed have significant assets that needed to be unwound, which one of your links (Guardian) actually states:

“A sale of assets belonging to Landsbanki, the bank that created Icesave, will provide much of the cash to reimburse the British and Dutch governments. Indeed, earlier this year an independent report estimated that the Icelandic people might be on the hook for as little as £125m”

The other was that the Icelandic government acted to protect their own depositors, but not those of other nations, despite the single Landsbanki licence being used in U.K. & Netherlands through passporting.

This is in your thisismoney link: “Iceland refused to pay compensation to foreign nationals, forcing the British and Dutch governments to step in and pay out billions of pounds in compensation to angry savers.”

That was the main beef at the time between the respective governments - that Iceland was favouring its own depositors, when by right a British/Dutch saver should have received the same ‘deal’ from the Icelandic government (as the home regulator of the passported licence)

So the U.K. government thought the Icelandic government should extend the same compensation terms to U.K. savers, and become the unsecured creditor to the bank instead. Since they didn’t, U.K. govt had to wait in line for the administration to proceed.

I assume when Leadsom was banging on about diplomacy having worked this was due to the Landsbanki in administration having been taken over effectively by the Icelandic state.

no need to be snippy :-)

that's good - I didn't know where to find high yield bond investment trusts

good 5yr TR - are there any other similar ITs?

The only way the ordinary Joe can help to moderate inflation is to cut back on consumption. Simply stop buying things. Don't put fuel in your car, walk or cycle. Don't eat out, eat at home and eat less. Turn down your heating. Only buy a new pair of shoes when the old ones fall off your feet.
And boycott shops cafes and restaurants which insist on electronic payment as opposed to accepting cash in the form of paper and coin.
One can monitor expenditure more easily using cash.
Also don't go on holiday. Have a staystation in the garden.
Also grow more of your food.
"Is anyone investing in fixed rate cash deposits again?"
My wife and I hold close to the maximum in premium bonds which can be likened to cash deposits with the chance, however miniscule, of winning a substantial amount.
Also I'm invested in NS&I index bonds which I've rolled over several times.
I like having a finger in most pies.

With regard to the point about spending less, frugality comes naturally to me so in some ways that's a no-brainer, and if it helps keep a lid on inflation, then we're increasing the real rate of return on our cash savings. But what happens if we all stop going to our favourite restaurants and local shops? Those businesses may never recover from the recession that follows. I'll be making savings where I can, but also planning a (no doubt eye-wateringly expensive) visit to a certain restaurant that I would hate to see disappear.
