Summary

Description	English: This is the time in years (Y-axis) that would be necessary for the BsF to lose 90% of its value if inflation was constant, at current inflation rates. Roughly, if it costs 1 BsF to buy one US dollar in 2012, the money will have lost 90% of its value when it will cost 10 BsF to buy US dollar (Dec 2014). It will have lost 90% of its value again when it will cost 100 BsF (Sep 2016), again when it will cost 1000 BsF (Jul 2017), and again when it will cost 10,000 BsF (Oct 2017). Yearly inflation rates vary enormously over a daily basis, for instance: 1 USD = 10,390 BsF (29 Jul 2017) 1 USD = 10,390 BsF (30 Jul 2017) 1 USD = 12,198 BsF (1 Aug 2017) 1 USD = 14,760 BsF (2 Aug 2017) 1 USD = 17,980 BsF (3 Aug 2017) 30 Jul daily inflation rate = 100(10390/10390 - 1) = 0%. 30 Jul yearly inflation rate = 100[(10390/10390)^365.24 -1] = 0% Time to lose 90% of value is not a finite number. 2 Aug 2017 daily inflation rate = 100(14,760/12,198 - 1) = 21.0% per day 2 Aug 2017 yearly inflation rate = 100[(14,760/12,198)^365.24 - 1] = 1.710³²% per year Time to lose 90% of value at 2 Aug inflation rate: 12.1 days. 3 Aug 2017 daily inflation rate = 100(17,980/14,760 - 1) = 21.8% per day 3 Aug yearly inflation rate = 100[(14,760/12,198)^365.24 - 1] = 2.010³³% per year Time to lose 90% of value at 3 Aug inflation rate: 11.7 days. Therefore, to inject sanity into this graph, the daily inflation rates are averaged over 301 days. In Excel for a given day X, this is computed as: =LOG(10; 1 + AVERAGE(daily inflation on day X-150:daily inflation on day X+150)) Data from dolartoday.com
