欧洲和日本已经维持了多年的负利率。然而，此举可能对央行保增长措施反而制造麻烦时会发生什么发出了警示。
That is the idea expressed last week by finance officials and others at the Reuters Global Investment Outlook 2020 Summit. They argue that the effects of below-zero interest rates are long-lasting and harmful.
这是上周金融官员等人士在《路透全球投资展望2020峰会》上表达的观点。他们认为，负利率的影响是持久且有害的。
Interest rates are negative when lenders – not borrowers – must pay interest.
负利率是指贷方必须支付利息，而不是借款方支付利息。
Critics say negative rates punish people who save money, cause problems for big banks and lead people to take bigger risks to get a small amount of interest.
批评人士表示，负利率会惩罚储户，给大型银行制造麻烦，并导致人们冒更大风险来获得小额利息。
About $12.5 trillion of the world's bonds, about 30 percent of the debt of countries in the developed world, pay negative interest. The Bank of Japan and the European Central Bank want economic growth and a small amount of inflation, so they have cut their interest rates to below zero.
全球约有12.5万亿美元的债券是负利率，它占到了发达国家债务的30%。日本和欧洲央行希望维持经济增长和温和通胀，因此将利率降为负利率。
However, a negative interest rate policy helps keep other interest rates, like the ones banks pay savers, low.
然而，负利率政策有助于将其它利率维持在较低水平，例如银行向储户支付的利率。
That means older people saving for retirement or in retirement are losing money, explained a recent blog post by BlackRock.

"It will be well down the list of the tools that they will use," he said.
他说：“它排在美联储会采用手段清单的下方。”
The moves by Europe and Japan's central banks have raised a question about what tools others, such as the U.S. Federal Reserve, have to fight a slowing economy.
欧洲和日本央行的举动引发了一大疑问，即诸如美联储之类的其它机构会采取什么手段应对经济放缓。
The U.S. central bank last month cut its overnight lending rate by a fourth of a percentage point to a target somewhere between 1.5 percent and 1.75 percent.
美联储上个月将隔夜借贷利率下调了1/4，降至1.5%到1.75%之间的目标水平。

"Never say never, but there is a real hesitancy here in the U.S. to take rates below (zero)," said Greg Peters. He is with the investment company, PGIM Fixed Income.

"I think the U.S. has had the benefit of seeing the (effects) of negative rates elsewhere," he added.
他还说：“我认为美国已经从观望其它地区负利率影响中受益。”
Negative interest rates do not always lead to an increase in lending and growing business investment.
负利率并不总是会导致贷款增加和商业投资增加。
Negative rates can cause financial organizations to earn less. If their profits are affected they might stop lending altogether and that would hurt the economy.
负利率会导致金融机构的收入减少。如果金融机构的利润收到影响，他们可能会完全停止放贷，这将会损害经济。
