Implications of Central banks’ negative policy rates on financial stability

Purpose: While central bankers have widely discussed the trade-offs of negative interest rates on monetary policy, the consequences of negative rates on financial stability are less well understood. The purpose of this paper is to examine the likely and possible financial stability consequences of a negative rates policy with particular focus on banks, short-term funding markets, foreign exchange markets, asset managers, pension funds and insurers. Design/methodology/approach: It draws from international experience with negative interest rates to identify financial stability threats posed to any economy by negative interest rates, and it also highlights where the US experience is likely to differ. Findings: In time, financial market threats and other logistical issues of a negative interest rate policy can be managed or overcome. Even cumulatively, these threats are likely to be small as long as the rates remain only modestly negative. However, if the rates remain negative for long periods or they become more sharply negative, the rewards of avoiding negative rates increase. Originality/value: Does the negative interest rate policy directly or through these challenges of implementation present a substantial obstacle to achieving financial stability objectives? As policy rates go negative in a greater share of the global economy, the financial stability consequences remain poorly understood and under discussed.
