Page 7  The objective is to extend the current Bank of England and FCA regulatory regimes for e-money and payment systems to cover the use ‘stablecoins’ for payments[7]. The powers in the Bill will extend not only to the systems for transferring such coins between parties to make payments, but to the issuance and storing of the coins. The Bank will have responsibility for such payment systems which are systemic or likely to become systemic. This will apply whether such systems exist to make payments for real things or for crypto assets should the latter activity become systemic in scale. We intend early next year to consult in detail the regulatory framework that will apply to such systemic payment systems and the services, like wallets, that accompany them. In doing so, we will be guided by the principle of ‘same risk, same regulatory outcome’ set out above. In the case of stablecoins used as money to make payments, the regulatory outcome has been expressed by the Financial Policy Committee of the Bank as an expectation that stablecoins used in systemic payment chains should meet standards equivalent to those expected of commercial bank money. And that's in terms of stability of value, robustness of legal claim and the ability to redeem at par in fiat[8]. Some of the likely foundational features of the regulatory regime on which we will consult are already clear.
Assuming constant returns to scale, perfect competition (so that factors of production are paid their marginal products) and Hicks-neutral technical change (so that shifts in the production function do not affect marginal rates of substitution between inputs), output growth can be expressed as a weighted sum of the growth rates of inputs and an additional term that captures shifts over time in the production technology. The weights for the input growth rates are the respective shares in total input payments – the labour and capital shares. More specifically:  where A(t) is a multiplicative factor in the production function capturing technical change.  K ,  L represent respectively the capital and labour shares of income. Charts 8 and 9 look at the proportion of labour and physical capital employed by the financial intermediation sector in the UK relative to the whole economy over the past forty years. They follow a not dissimilar path, with both labour and capital inputs rising as a share of the whole economy for much of the period. The proportion of labour employed by finance rises by around 50% between 1977 and 1990, while the proportion of capital almost trebles from 4% to 12% over the same period. Financial liberalisation over the period drew factors of production into finance, both labour and capital, on a fairly dramatic scale. Perhaps the most striking development, however, is what happens next. These trends have not persisted during this century.
