That said, financial system frictions limit the favorable impact from modestly negative nominal rates, but our experience with them remains limited. Given the likely need for unconventional policy tools to address the next recession, learning more about the benefits and costs of negative nominal interest rates is a high priority.
Stylized Facts. It is important to distinguish between nominal interest rates—which you can find online or in the financial press—and real interest rates, which are adjusted for inflation. For most investment decisions, the real interest rate matters.
Yet, without attracting great attention, over the past 25 years real interest rates have frequently been negative. For example, since , the German and U. We plot the ex post real interest rate. But, given the stability of inflation, ex ante real interest rates computed using inflation expectations have very similar properties.
One-year real interest rates on government debt, October Note: The real rate subtracts past month inflation from the current nominal rate. This implies that expected inflation equals actual inflation. While real interest rates have frequently been negative, virtually all the market and media attention has focused on the fact that, in recent years, nominal interest rates fell below zero. Denmark and Switzerland have set policy rates as low as Today, short-term money market rates in Denmark, Germany and much of the euro area , Japan, Sweden, and Switzerland all remain below zero see chart.
Most of these are sovereign debt issued in Europe and Japan, but some long-term, high-grade corporate liabilities are also trading at yields below zero.
For many years, nearly all economists and market participants acted as if nominal interest rates could never sink below zero, believing that households and firms would prefer cash which pays zero to any instrument offering a lower yield see the discussion here. However, the notion of a zero lower bound ZLB ignores the elevated transactions costs of using cash—including storage, transport and insurance costs—compared to instruments that trade and settle electronically.
Today, we speak of an effective lower bound ELB , which differs from the ZLB solely because of the costly frictions associated with using cash. No one knows the precise level of the ELB. What we do know is that anything that raises the transactions cost of using cash—such as eliminating the largest-denomination currency notes as the ECB did with its euro note in —tends to lower the ELB for details, see our posts here and here.
So, it surely fluctuates, albeit modestly. Importantly, if interest rates were to sink temporarily below the ELB, at least some households, businesses, and institutional investors would shift from bank deposits to holding cash, putting a floor under nominal interest rates.
Indeed, if a central bank were to push its policy rate below the ELB on a persistent basis, the switch could make the policy contractionary as depositors flee banks into paper bank notes, undermining banks as a key source of credit.
Why do some central banks wish to set interest rates modestly below zero? The answer is that it provides added room for stimulating aggregate demand and securing price stability. This makes it far more likely that central banks will run out of conventional monetary policy space the next time the economy turns down. Indeed, in several economies, inflation has languished below the central bank target even in the presence of negative rates.
In practice, most central banks that impose negative rates only impose the lowest headline rate on a fraction of bank reserves. That is, they practice tiering to diminish the impact on bank profits. For example, the Bank of Japan pays a positive rate on a base level of reserves, a zero rate on an amount that increases with the total level outstanding, and a negative rate only on the marginal reserve holdings see here.
Similarly, in September , the ECB adopted a two-tier system that exempts part of excess reserve holdings from the negative deposit facility rate which currently pays Attempting to regain growth, central banks have taken increasingly forceful monetary measures. Of these, perhaps the most controversial and least understood is negative interest rates. The central bank of Denmark was the first to go below zero, in To the surprise of many, it did not result in stress in the financial system.
Two years later, so did the Bank of Japan. Setting interest rates to below zero is often viewed as an unconventional policy, but it can actually be seen as a continuation of the perfectly normal monetary policy practice of moving the short-term interest rate in response to fluctuations in the economy.
There is a limit to how low interest rates can go, but it turns out that this limit is not zero and we have not reached it yet. Interest rate cuts below zero largely work as they do in normal times with positive interest rates, though there are some differences: the effects on banks, for instance, and the psychological impact of interest rates plunging into negative territory more on this below.
Throughout history, it was widely believed that central banks could not move short-term interest rates below zero. After all, why would anyone pay to deposit money in a bank or pay to lend someone money, when they could just keep their cash at home for free? Cash always has a zero interest rate. It was widely believed that if interest rates did dip below zero, even if by a very small amount, everyone with savings would run to the bank to change them for ready money.
The zero interest rate on cash was seen as the lowest point an interest rate could dip to, the point at which central banks would be out of ammunition. In the 19th century, Silvio Gesell proposed a tax on holding cash. In , Greg Mankiw suggested a lottery scheme for randomly picking serial numbers on bank notes and declaring them void, making it risky to hold on to cash. In , Kenneth Rogoff explained that if we could just phase out cash altogether, there would be no alternative to paying a negative rate on bank deposits and bonds.
And there are other proposals, too. When central banks started dropping interest rates to below zero without adopting any measures to make cash costly to hold, it changed the prevailing worldview. Zero was no longer the lower bound on interest rates.
It turned out that many were actually willing to pay for the convenience of not having to hold their savings in cash. The example of Switzerland suggests that interest rates can go at least as low as Views have been voiced on where the effective lower bound might be and what it depends on. But in the end, we still do not know; no country has reached this point, and it remains unknown just how much further interest rates can be cut before we see a broad shift into cash.
Central banks hold money for commercial banks. If the interest rate is cut below zero, it means that they, the central banks, can charge the commercial banks interest on that money. The commercial banks, meanwhile, can cut the interest rate that they charge their customers by the same amount and make their money back; although there are some crucial exceptions for some bank deposits, which we discuss later. Imagine a pension fund is holding a deposit with a commercial bank.
If the interest rate drops, the fund might seek to buy financial assets with a higher return, such as bonds which are like long-term loans. This increases demand for, and therefore the price of, these assets, which is how the rate cut is transmitted to the broader financial market.
To compete with cheaper capital-market financing, banks might also reduce the interest rates they charge on loans. Ultimately, the aim of the central bank is to increase economic activity and spur inflation from the low or even deflationary levels that some countries are currently in danger of.
There are at least four ways this can happen:. Some have argued that in countries with ageing populations, incentives to spend will fall on deaf ears.
Faced with negative interest rates, savers and retired people who live off their pensions could be more likely to reduce their spending, because they either have fixed savings targets or because they live off the interest from their capital.
There is no evidence that savers as a whole suddenly react in this new way to interest rate cuts into negative territory, however. The fact is that for every saver in an economy, there is someone on the other side borrowing this money. Think of new house owners with high mortgages and car loans, start-up companies — or even the government.
The increased purchasing power of borrowers due to negative interest rates might easily make up for the supposed frugality of retirees and other savers, as explained here. Have you read? Why is everyone talking about negative interest rates?
What the central bankers' central bank thinks about negative interest rates What does a central bank actually do? Inflation in this case amounts to a negative real interest rate. So the real interest rate, which really matters for the value of your savings, depends on the nominal interest rate, but also on inflation. In countries where the inflation rate is higher than nominal interest rates, real interest rates are negative, and your savings fall in value according to what you can buy for them.
In countries where inflation is lower than the nominal interest rate, on the other hand, the real value of your savings increases. Personal Finance. Your Practice. Popular Courses. Economics Macroeconomics. Key Takeaways A negative interest rate policy NIRP occurs when a central bank sets its target nominal interest rate at less than zero percent.
This extraordinary monetary policy tool is used to strongly encourage borrowing, spending, and investment rather than hoarding cash, which will lose value to negative deposit rates. Officially set negative rates have been seen in practice following the financial crisis in several jurisdictions such as in parts of Europe and in Japan. Compare Accounts.
