Ann: FY23 Results Investor Presentation, page-41

Thanks for sharing. On the float interest earnings I can easily get to a higher number.

For them to get to 1.84% average yield, that rate has been growing, and assuming that rates have been growing at 0.15% per month (which is 12 months to go from roughly 0% to 1.8%), and the June half average means it's measuring the rate from around March, means that the June 2023 end rate should be about 1.85% + 3months * 0.15%/month = 2.3%. On $2.6bn that's $60m already.

But rates are still going up, there's about 0.5% of raises in Europe/UK since late June which is another $13m if it holds for the year, so we're close to $75m assuming no more rate rises. And they've said previously they expect to earn about the central bank rate over time which could mean >4%.

And that's assuming no increase in dollars of float which was up 30% during FY23. Lots of potential upside here.
