In 1995, Fischer Black, an economist whose ground-breaking work in financial theory helped revolutionise options trading, confidently stated that “the nominal short rate cannot be negative.” Twenty years later this assumption looks questionable: one quarter of world GDP now comes from countries with negative central bank policy rates. Practitioners have been forced to update their models accordingly, in many cases introducing greater complexity. But this shift is not just academic. Models allowing for a wider distribution of future rates require market participants to hedge against greater uncertainty. We argue that this hedging contributed to the volatility in global rates in early 2015, but that derivatives can also play an important role in facilitating monetary policy transmission at negative rates.

Since QE began, banks have had a lot more liquidity to make payments. But some have argued (in a nutshell) that banks are reliant on this extra liquidity to make their CHAPS payments and it would be difficult to remove it from the system. Our analysis shows that banks don’t need a great deal of liquidity to make their payments simply because they recycle such a high proportion of them. In practical terms, banks do not rely on high reserves balances to make their CHAPS payments so unwinding QE shouldn’t have any impact on banks’ ability to do just that. We also briefly go over the potential reasons for this such as the CHAPS throughput rules, the Liquidity Savings Mechanism, and the tiered structure of CHAPS.

Over the last twenty years, the BOE has carried out a number of reforms to its operational framework which have been partly intended to reduce money market volatility. My analysis suggests that these have been successful. Overnight volatility fell by around 90% since the early 2000s and much of this can be explained by the BOE’s reforms. But I find little evidence that this affected the volatility of term rates, which are more important than overnight rates for monetary policy transmission. Therefore, central banks might consider giving less priority to money market volatility when designing their future operating frameworks.

Peer-to-peer lending platforms (P2P platforms) emerged after the financial crisis by catering for pent-up demand for unsecured borrowing from individuals and small businesses. Ten years after the conception of P2P platforms, the question is whether they may soon start to penetrate more mainstream lending markets and thereby challenge high street lenders. For example, according to the latest survey compiled by Nesta, P2P lending for the year 2015 was the equivalent of 3.9% of new loans lent to SMEs, although the outstanding stock of P2P lending is much lower. This post considers how seriously in practice to take this threat to the traditional banking model.
