Decline in the volatility of bitcoin

May 25, 2016

Bitcoin is widely considered a highly volatile asset. Both the Consumer Financial Protection Bureau and National Association of Attorneys General have cited volatility as a significant risk of holding bitcoin. One might debate the extent to which volatility is a problem for routine users, but there is no denying that volatility has declined significantly.

Eli Dourado maintains the Bitcoin Volatility Index, presented as a solid blue line in the chart above. Volatility—or the amount by which the price varies over time—is measured as the standard deviation of daily returns for the preceding 30-day window. The volatility of bitcoin has fallen from an average of 3.19% in September 2010 to 0.96% in April 2016. The dashed grey line represents the linear trend of volatility over the entire series. Volatility has decreased significantly.

Why has volatility fallen? As Jim Harper noted last September, bitcoin’s volatile price is a reflection of (1) uncertain future use and (2) thin markets. As the network of bitcoin users increases and demand becomes more stable, volatility should fall. And it has.

To be sure, the price of bitcoin remains more volatile than other major currencies. But the gap is shrinking.
