The creation of new knowledge is the bedrock of Saga. Every facet of our currency is underpinned by thorough industrial scholarship. An interdisciplinary effort, Saga’s papers are authored by leading subject-matter experts, and a rigorous and ongoing cross-pollination of economics, mathematics, and social sciences.
An Asset-Backed Currency
Participants can both buy and sell SGA directly from Saga’s smart contract - acting as a market maker. For direct purchase of SGA, Participants, registered SGA Holders, send funds to Saga’s smart contract, where they are kept as part of the variable reserve of conventional currencies, hosted by reputable banks. The primary purpose of Saga’s reserve is to ensure Participants can sell SGA; the contract will always offer to buy SGA, drawing on funds from the reserve.
Restrained Price Volatility
SGA’s price reflects market demand which would (naturally) fluctuate over time. However, price volatility is moderated by the interplay between the money supply and the reserve; when buying and selling SGA, Saga’s smart contract adjusts the money supply to meet market demand. Therefore, the reserve acts as a buffer, limiting the impact of market fluctuations. In practice, when the economy expands, the contract increases SGA supply, slowing price appreciation. Conversely, when Saga’s economy shrinks, the contract reduces the money supply, thereby curbing any large drops in SGA price. Within the range set by the contract’s bid and ask prices, Saga operates a price band. When the price in secondary markets deviates from the price band, the contract intercedes, altering the supply of SGA. The price band is designed to limit price volatility, while allowing the secondary market to freely set the price within the band. The width of the price band is designed to increase as Saga’s economy matures, allowing the secondary market to exert increased influence. In practice, when the economy expands, the contract increases SGA supply, slowing price appreciation. Conversely, when Saga’s economy shrinks, the contract reduces the money supply, thereby curbing any large drops in SGA price.
SGA price is based on two sources of value: (i) its variable reserve backing of conventional currencies (ii) inherent value The fraction of value based only on the reserve is known as the reserve ratio. The reserve ratio can also be viewed as a measure of market trust in Saga. Here we observe an inverse relationship: the higher the trust, the lower the reserve ratio. Saga’s reserve-based value is a stabilising factor. While stability is prized, the limitation is clear: in a fully backed currency there can be no price appreciation. The internal value of a currency is prone to volatility: it can both rise and fall, reflecting the strength of the economy it represents.
Stability & Growth
This delicate balance, the interplay between reserve and inherent value, should be managed to allow SGA price to grow along with its economy, while controlling volatility. When the economy is small－and the inherent value is especially volatile － Saga applies a high reserve ratio, supporting stability. As the economy grows and volatility decreases, Saga’s reserve ratio decreases in tandem, encouraging growth in SGA price. Saga’s price volatility is always restrained－a substantial cash flow is needed to dramatically alter SGA price. When the economy is small, the high reserve ratio protects it. When the economy is large and the reserve ratio is low, its sheer size ensures stability.
Counter Cyclical Measures
Should Saga’s economy shrink, the contract will deliberately increase the reserve ratio. This enhances the volatility-restraining mechanism, acting as a counter-cyclical boost to the economy. A higher reserve ratio will alleviate panic, and help stimulate a recovery.
