Interesting chart. Thanks.

Looking at the 1950 peak, I believe interest rates back then were around 0.5%. Looking at the lows and that coincided with periods of higher interest rates.

Would be interesting to see the progression for a cost to service debt, debt level x interest rate being paid. But even though that might be a smoother line, would also be nice to see how much was actual external debt, rather than for instance as of present when the BoE holds around a third of the Treasury's Gilts (debt) and returns all interest paid on those gilts back to the treasury.

Here is the corresponding interest paid as a percentage of GDP chart

and a similar graph which shows interest payments from 1980 onwards.

Of course these are for the total interest paid and don't take into account that a large part is being paid back to the treasury since QE.

Here is a spreadsheet of interest rates since 1694. After the war interest rates were at 2% until 1951.
