“Amortization Requirements May Increase Household Debt : A Simple Example,” IMF Working Paper No. 16/83, April 2016.
The idea is very simple. If you like to have a mortgage of SEK 2 million the next 10 years, you would take out an interest-only mortgage of SEK 2 million now and keep it for 10 years. However, if you learn that new amortization requirements imply that you have to pay back 2 percent of the initial mortgage every year, you would prefer to borrow SEK 2.5 million now, put the extra SEK 0.5 million in a savings account, and then use withdrawals from the savings account to amortize 2 percent of SEK 2.5 million each year, that is, SEK 50,000 each year and SEK 500,000 in 10 years. Thus, if an LTV cap is not binding you would borrow SEK 2.5 million, or as much as the LTV cap allows you to borrow. Continue reading
A simple and transparent framework for cost-benefit analysis of “leaning against the wind” (LAW), that is, tighter monetary policy for financial-stability purposes, is presented. LAW has obvious costs in the form of a weaker economy if no crisis occurs and possible benefits in the form of a lower probability and smaller magnitude of (financial) crises. A second cost—less obvious, overlooked by previous literature, but higher—is a weaker economy if a crisis occurs. For representative empirical benchmark estimates and reasonable assumptions the result is that the costs of LAW exceed the benefits by a substantial margin. The result is robust to alternative assumptions and estimates. A higher probability, larger magnitude, or longer duration of crises—typical consequences of ineffective macroprudential policy—all increase the margin of costs over benefits. To overturn the result, policy-interest-rate effects on the probability and magnitude of crises need to be more than 5–40 standard errors larger than the benchmark estimates.

Monetary policy should stick to its core mandate of price stability, and should deviate from its traditional role only if the benefits to the economy outweigh the costs, according to a new study from the International Monetary Fund, “Monetary Policy and Financial Stability.”
The question is whether monetary policy should be altered to contain financial stability risks. Should it lend a hand by temporarily raising interest rates more than warranted by price and output stability objectives?
Based on our current knowledge, and in present circumstances, the answer is generally no.

Riksbankens mandat bör förtydligas, sysselsättningen ges större vikt, den demokratiska kontrollen av Riksbanken skärpas och koordineringen av penningpolitiken och makrotillsynen förbättras. Det skriver jag i den nya underlagsrapporten Penningpolitik och full sysselsättning för LOs projekt Full sysselsättning och solidarisk lönepolitik. Continue reading
