And as if this was not blatant enough, all this occurred in a climate of malicious rumors about the RMB and the Hong Kong dollar, glorified by publications from the so-called in-house currency strategies and analysts, and by the usual “reliable information from authoritative sources”. Well, it did not quite work out the way they intended. They miscalculated on two counts. First, they did not factor in the need for the HKSAR Government funding this year’s budget deficit, unexpected at the time when the budget was drawn up, through a drawdown of foreign reserves. And so the currency board adjustment mechanism involving sharply higher BIS Review 85/1998  -4-  interest rates was not triggered. Second, they did not realize that the HKSAR Government was far from the sitting duck they thought we were. Committed to the free market as we may be, we took the view that free markets do not mean that markets can be freely manipulated. They need to be fair markets as well. We have a responsibility to tackle market manipulation and avoid serious market dislocations developing. So after much agonizing we acted on two fronts. First, we intervened in the stock and futures markets to deter market manipulation, by making sure that the manipulation did not pay off. Second, we followed this action through with various measures to strengthen our monetary and financial systems. On the monetary side, we introduced technical measures to modify our currency board arrangements of our linked exchange rate system to make it less susceptible to manipulation.

Third, the split into prices and real output and the overall outturn for the economy, depend on what else is happening at the same time: monetary policy is just one of the various forces at work shaping the pressures on output and inflation. We don’t conduct monetary policy in a scientific laboratory where everything else can be held constant. QE is often described as being a great experiment. In fact, the theory of monetary policy in the economic textbooks that I was brought up with at Bristol, and later, all considered the supply of money to be the central bank’s primary policy instrument. The use of interest rates to set monetary policy appeared to be viewed by many academic authors as something of a slightly unfortunate and uninteresting practicality8. I want to be clear about one very important point: for monetary policy to stimulate the economy, the Bank of England has to cut interest rates and/or increase the supply of money. That gives firms and households an incentive to spend rather than to save.
