Intermediation among non-residents The third set of characteristics involves the provision of intermediation among non-residents. The Eurodollar market provides efficient intermediation among non-residents. For example, it allows for Eurodollar bonds to be issued by non-US entities and bought by non-US investors. To an increasing extent, the offshore RMB market is functioning as a platform for RMB financial activities conducted by non-residents. The pool of RMB deposits in Hong Kong, being deposits of mainly non-Mainland individuals and corporates, is exceeding RMB 800 billion. Adding to that is the dim sum bond market, which has a size of RMB 260 billion at present. Offshore RMB bonds are being issued by Mainland Chinese entities as well as multinationals, and they are being bought by offshore investors. At the same time, banks in Hong Kong are extending RMB loans to customers, with the outstanding amount of such RMB loans currently stands at close to RMB90 billion. 2  BIS central bankers’ speeches  As the market deepens and a greater variety of RMB products become available offshore, we will eventually see more RMB intermediation within the offshore markets, especially as non-Chinese residents become willing borrowers of RMB. However, for that to happen, work on different fronts needs to be pursued and market efficiency furthered through innovative solutions and active participation by different market players.
But even though the zero lower bound is not absolute, the effect of further cuts will diminish as rates approach or fall below zero. The most important limitation on how far down it makes sense to go is related to the existence of an alternative to bank deposits, i.e. cash. Negative bank deposit rates can always be avoided by holding cash instead. The disadvantage is that cash is more expensive to manage than electronic deposit money. Transport, storage and security all involve costs. For a bank participating in the settlement system, where large amounts are reinvested at frequent intervals across accounts and across banks, the costs involved in switching to cash will be considerable. Central bank deposit rates can therefore be below zero. How far below, is an open question. For many retail customers, exchanging bank deposits for cash will be fairly inexpensive. A safe deposit box can be rented for less than € a year. If bank customers choose to withdraw their deposits and hold cash, banks will lose an important part of their funding. This is probably an important reason why banks in countries with negative policy rates are reluctant to set negative deposit rates, particularly for households. If banks hold back on deposit rates, lending rates can only fall to a limited extent before banks’ earnings are reduced. A lower policy rate will probably have a less-than-normal effect on lending rates, weakening the impact of monetary policy via the demand channel.
