Opposing change? The price impact of removing the penny

Marilena Angeli and Jack Meaning

Would removing the 1p and 2p coins from circulation cause inflation? Or deflation? Or neither? Our analysis, and the overwhelming weight of literature and experience, suggests it would have no significant impact on prices because price rounding would be applied at the total bill level, not on individual items and it would only affect cash transactions, which make up a low proportion of spending by value. Even if individual prices were rounded on all payments, analysis of UK price data suggests no economically significant impact on inflation.

Would a Central Bank Digital Currency disrupt monetary policy?

Ben Dyson and Jack Meaning

A “Central Bank Digital Currency” (CBDC) may sound like it’s from the future, but it’s something that many central banks are researching today, including those in Sweden, Canada, Denmark, China, and the European Central Bank and Bank of International Settlements (BIS). In a new working paper, we set aside questions about the technological, regulatory and legal aspects of central bank digital currency, and instead explore the underlying economics. Could the existence of a CBDC make it easier or harder for central banks to guide the economy through monetary policy? And could the existence of CBDC make the monetary transmission mechanism (MTM) faster or slower, stronger or weaker?

Core Design Principles for a Central Bank Digital Currency

Clare Noone and Michael Kumhof

Does the introduction of a central bank digital currency (CBDC) crowd out bank funding? Does it open the door to runs on the aggregate banking system? In a recent Staff Working Paper we provide insights on these questions. We find that some of the major risks to financial stability posed by CBDC can be addressed by a set of four core design principles for a CBDC system. Implementing these principles, however, is non-trivial and risks would remain.

Algos all go?

Francis Breedon, Louisa Chen, Angelo Ranaldo and Nicholas Vause

Most academic studies find that algorithmic trading improves the quality of financial markets in normal times by boosting market liquidity (so larger trades can be executed more quickly at lower cost) and enhancing price efficiency (so market prices better reflect all value-relevant information). But what about in times of market stress? In a recent paper looking at the removal of the Swiss franc cap, we find that algorithmic trading provided less liquidity than usual, at worse prices, and that its contribution to efficient pricing dropped to near zero. Market quality benefits from a diversity of participants pursuing different trading strategies, but it seems this was undermined in this episode by commonalities in the way algorithms responded.

Sterling weakness: FX mismatch risks in the UK corporate sector

Rajveer Berar

What could falls in sterling mean for UK firms’ ability to sustain foreign currency (FX) debt obligations? The value of sterling began falling around two years ago and dropped further after the EU referendum – remaining around these lower values ever since. There is every possibility that sterling may stay low for the foreseeable future – creating both potential winners and losers. In this piece, I investigate one particular channel for losses related to sterling weakness: whether UK firms could find meeting their FX debt obligations more challenging. By reviewing market intelligence, market prices and derivatives databases, I find limited evidence that sterling weakness has yet produced any significant changes to UK firms’ ability to manage their FX debt obligations.

A LOOPy model of inflation

Alex Tuckett

The Law of One Price (LOOP) is an old idea in economics. LOOP states that the same product should cost the same in different places, expressed in the same currency. The intuition is that arbitrage (buying a product where it is cheap and selling it where it is expensive) should bring prices back into line. Can LOOP help us understand UK inflation? Yes. I find EU prices have much higher explanatory power for UK prices than domestic cost pressures, and the effects of exchange rate changes last longer, but build more slowly than commonly assumed.

Beyond blockchain: what are the technology requirements for a Central Bank Digital Currency?

Simon Scorer

What type of technology would you use if you wanted to create a central bank digital currency (CBDC) i.e. a national currency denominated, electronic, liability of the central bank? It is often assumed that blockchain, or distributed ledger technology (DLT), would be required; but although this could have some benefits (as well as challenges), it may not be necessary. It could be sensible to approach this issue the same way you would any IT systems development problem – starting with an analysis of requirements, before thinking about the solution that best meets these.

Bitesize: The very volatile value of cryptocurrencies

John Lewis

Proponents of private cryptocurrencies argue they are a better store of value than traditional “fiat” currency. But even if a cryptocurrency’s value cannot be inflated away by large supply increases, that doesn’t automatically mean its value is stable in terms of ability to buy goods and services.
