Dreaded disruptions to the monetary policy transmission channels as well as adverse side effects on bank profitability have so far largely failed to materialise. Thus, the evidence available today shows that the negative interest rate policy is an effective policy tool. However, systemic risks, including in the non-bank sector, should be closely monitored as negative rates are expected to remain low for longer.

The entry into negative territory raised several concerns about its effects on the transmission of monetary policy and possible side effects. • The decade-long decline in the natural rate of interest suggests that a low interest rate environment may be here to stay for a prolonged period in advanced economies. This trend may necessitate the more often usage of NIRP after significant macroeconomic shocks. • Policy rate cuts in negative territory have successfully eased financial conditions in largely similar ways as standard interest rate cuts. The interest rate channel of transmission was effective as evidenced by prevalent money market rates and a downward shift of the government bond yield curve. Market participants’ expectations of future short-term interest rates were successfully steered towards negative territory. The credit channel effectively raised credit growth to households and the non-financial sector. • Concerns of a muted policy rate pass-through towards bank clients only partly realised. Banks were expected not to charge negative rates from clients, which could disrupt policy transmission and severely impact profitability. While this did occur for deposit rates of households, it did not for non-financial corporates. Causal evidence of the negative effect on credit supply for banks most reliant on deposits and consequently most exposed to NIRP is inconclusive. • There are several systemic risks associated with NIRP: it may reduce bank profitability by eroding the interest rate income of banks, may create asset price bubbles, or hurt the yield on pension savings. In search for yield, banks can lend to riskier counterparties, invest in riskier assets, and thereby endanger financial stability. • Evidence suggests that banks prevented severe adverse effects on their profitability by modifying their business strategies and have benefited from other factors not guaranteed to persist in the long run. Empirical evidence suggests that clients did not significantly withdraw their deposits which would endanger bank funding. Further, banks realised gains on their fixed income assets, against which they could also borrow more on wholesale markets, and decrease their loan loss provisions. • While the impact of monetary policy rates on real estate prices is an important transmission channel, housing is also a crucial part of households’ wealth and consumption spending. From a consumer perspective, asset price inflation affects the decision to acquire home ownership and rental rates. International evidence suggests that a one percentage point decrease in the interest rate will cause an increase in real estate prices of 6% to 8% over the following three years. • NIRP may adversely affect non-monetary financial intermediaries (NFMI). A protracted low interest rate will hit the solvency status of NMFIs and plan sponsors depending on the extent to which they guaranteed minimum returns. NMFIs may implement riskier strategies to meet their obligations. Beneficiaries of non-guaranteed pension products will have to bear the low return on assets. Due to limited available data, there is little evidence on effects on NFMIs. • The evidence points towards cautious optimism regarding NIRP as a monetary policy instrument. So far, it cannot be associated with significant adverse effects. The empirical assessment suggests that it has delivered on its objectives and has worked similarly to standard PE 662.920 6 Low for Long: Side Effects of Negative Interest Rates nominal interest rate cuts. The main adverse effects of NIRP, i.e. the disruption of monetary policy transmission as well as financial fragility arising from low bank profitability and an excessive pressure for cash hoarding, have not yet materialised in the euro area. • Ongoing assessment is needed to understand whether market participants can continue to cope with the pressure on profitability in negative territory when policy rates decrease further and/or remain on this level for years to come.
