In an overdue move not very surprising, Jagex has followed up on the recent loyalty points, squeal of fortune, and solomon's store with a new in-game item that connects the three and allows RuneScape players to legally acquire real world benefits with their gold. This was released September 25th, 2013.
The new item, bonds, can only enter the game by buying for $5 or equivalent currency. The bonds can then be used in-game or traded. One bond is worth 14 days of membership, Eight spins on the squeal of fortune, or 160 runecoins.
Bonds can be traded to another player or sold on the grand exchange. Although listed slightly over 12 million, the current street value is about seven to eight million coins each.
What motivates bonds to enter the game is the first really viable, legal real world trading option. RuneScape players buy bonds with real money and then sell on the grand exchange or through trade to other players. Players who tend to not be able to accumulate money in game or who are poor would be more motivated to buy the bonds and sell in-game.
What motivates bonds to leave the game is rich players now don't have to pay real money for membership, spins, or runecoins. Instead, they can purchase bonds from the grand exchange or from other players to use.
At current value, a spin is worth almost a million coins. Because almost all rewards are worth less, this option will probably be used by players trying to win special offer items.
At current value, a runecoin is worth about 50k. RuneScape players who want cosmetic rewards can pay in-game gold for them in place of real money.
At current value, a month of membership costs about 16 million coins. Rich RuneScape players will be able to purchase membership using gold coins instead of real money.
There is no limit of how many bonds that can be brought into the game, but because bonds can only be exchanged for real world value in membership and in-game benefits, RuneScape players will only need to use two bonds a month plus whatever runecoins and spins they want to buy. Other than that, there is no monetary gain for having RuneScape gold.
Thus, the demand or lack of thereof plus the supply will set the value of the bond, a balance between how little gold players are willing to get for $5 and how much gold they are willing to pay for membership and extras.
You can only buy one bond per offer on grand exchange slot, and once traded, bonds are untradable unless right clicked and made tradable. This costs 10% of their current value. Bonds do not stack in bank.
