One of the easier proxies to use, when determining the relative buying power of coins in Runescape 3 versus Oldschool Runescape (and thus, over time, comparing inflation-rates between the two games) is market values of bonds. This market, then, is an attempt to predict the relative inflation rates in Runescape 3 versus Oldschool Runescape, using bond-values as a proxy.

As of the time of this market's creation, the 

market value of Oldschool Runescape bonds

 is 10,698,556 coins. The ratio between these two numbers is ~8.68. I will reapply this ratio-calculation—based on the values at those same links, should the links remain live, or otherwise at the closest equivalent tracking-links I can find—based on the values on 2024-06-30 to determine what number this market ends up resolving at. If the ratio is below 6, the market will resolve to 6, and if it's above 11 the market will resolve to 11.
