I know this is probably a question for Finance SE, but they are an intimidating bunch over there - I hope somebody here may be able to help.

With the recent turmoil, I thought I should really try to understand how the economy works, in order to make the best decisions with my money. So this morning I decided to hop to my favourite newsagent and treat myself to a copy of the Financial Times. I wasn't ready for what I found!

Puzzlers, I'm puzzled! None of those graphs make sense to me, there are pages full of tiny numbers, and I haven't even got a clue what the ads are trying to sell me!

I copied an example below. There wasn't a caption, so I have no idea what it is. I wonder if someone could explain it to me - I am sure Economics is one of those things where you only need to get started, then you can work out the rest.

    $\begingroup$ @nine9, you've already found the key - or part of it... $\endgroup$ Commented Nov 2, 2022 at 13:55

1 Answer 1


Step 1 (as solved by @nine9)

Highlighting the low values of the grid gives us "Vigenere"

enter image description here

Step 2

It's an autokeyed Vigenere cipher with an initial key of "Vigenere". Autokey meaning the full key is initialKey + plainText
