OK, Friday’s charts were perhaps a bit too fiendish. We wanted them to be challenging so that we wouldn’t have to pick a winner from a dozen correct entries, but it turned out that no one completely nailed all three.

Here are the correct answers:

This shows UBS’s quarterly net income since the 1990s. It can thank Credit Suisse for the accounting gain that produced that last spike.

This shows the share price of the Grayscale Bitcoin Trust after a judge ruled that the SEC was wrong to reject Grayscale’s application to turn it into an ETF.

And this showed the overall short interest of hedge funds in US Treasuries, going by CFTC data. Perhaps unsurprisingly, this one was the hardest chart to guess, and only one person got it right: Oliver Felix from Swiss Re.

Oliver nailed the first chart as well, and only failed to get a perfect record by guessing that the second one showed the price of bitcoin in $’000s after the GBTC ruling, rather than GBTC itself. But having discussed this within FTAV Towers, that’s still close enough to earn him the t-shirt. So congratulations to Oliver!

The next charts quiz will land around midday UK time on Friday, and we’ll try to make it (moderately) easier.
