It is a central argument of the financial repression literature that i
nterest rates should be determined by the market to reflect the true c
ost of capital. This article suggests that the notion of an 'equilibri
um interest rate' may be undefined since the rate required to balance
financial markets differs from that required to equilibrate savings an
d investment. Thus liberalisation introduces an intrinsic instability
into the financial system as a result of portfolio adjustment. The art
icle examines the Chilean and Korean experiences and concludes that a
sustainable reform requires positive but low real interest rates and b
road regulation of the financial system to ensure macroeconomic stabil
ity.
