And that's basically deflation 50 percent deflation.

In the summer of 2003, public debate and market sentiment in the euro area were influenced by Japan s protracted deflation and the expectation of a possibly severe disinflationary process in America. Some observers saw a risk of sustained deflation in the euro area as well.

Deflation Doldrums?

In 2003, an IMF study raised the specter of Japan like problems around the world, and listed thirteen countries, including, China, Germany, Singapore, and Poland, with a moderate to high risk of deflation. Yet, in the face of overwhelming evidence of the importance of inflation or deflation risk, most people even in countries that have been warned generally still have not taken steps to protect themselves.

Policymakers will have to worry about a strange beast called stag deflation (a combination of economic stagnation recession and deflation) about liquidity traps (when official interest rates become so close to zero that traditional monetary policy loses effectiveness) and about debt deflation (the rise in the real value of nominal debts, increasing the risk of bankruptcy for distressed households, firms, financial institutions, and governments).

The Deflation Bogeyman

Deflation and Democracy

Inflation or Deflation?

Deflation fears were mistakenly raised in 2001 2003, when the strong response of the US housing market and consumer spending to lower interest rates should have made the debate redundant. Influenced by a misreading of the Japanese experience, this led to excessive protection against the tail risk of deflation.

Can China Beat Deflation?

Can China Avoid Deflation?

Southern Europe could enforce deflation.

Deflation in many advanced economies.

Has Global Stag Deflation Arrived?

That's a 50 percent deflation rate.

In 2010, when it began raising its policy rate to contain financial excesses, it put price stability at risk. Before long, Sweden had succumbed to deflation, from which it is still struggling to recover.

Why Deflation is Good News for Europe

Similarly, the risk of deflation worldwide has been contained via exotic and unconventional monetary policies near zero interest rates, quantitative easing, credit easing, and forward guidance. And the risk of a war between Israel and Iran has been reduced by the interim agreement on Iran s nuclear program concluded last November.

The renminbi has appreciated sharply over the past several years, exports are sagging, and the risk of deflation is growing. Under these circumstances, many suggest that a reversal in Chinese currency policy to weaken the renminbi is the most logical course.

In fact, those who advance this view which is the most powerful obstacle to radical ECB action have their analysis upside down. Under current conditions, with the inflation rate dangerously close to zero, governments are reluctant to do anything that increases the risk of deflation.

BRUSSELS The International Monetary Fund now estimates a 30 risk of deflation in the eurozone, and growth figures within the monetary union continue to disappoint. But policymakers seem trapped in a cat s cradle of economic, political, and legal constraints that is preventing effective action.

Indeed, the risk for the world economy is actually tilted toward deflation for the 23 advanced economies in the sample, even eight years after the onset of the global financial crisis. For this group, the median inflation rate is 0.2 the lowest since 1933.

In terms of price performance, that's a 40 to 50 percent deflation rate.

Jens Weidmann, the president of the German Bundesbank, remains openly skeptical. Though Weidmann does not deny the risk of deflation, he argues that the consequences of recent price data may be less serious than believed, while those of full fledged QE could be more serious than assumed.

Deflationary pressures eased in Japan but firm evidence that deflation has ended is still awaited.

Ironically, although central banks are now focused on the problem of deflation, the more serious risk for the longer term is that inflation will rise rapidly as their economies recover and banks use the large volumes of recently accumulated reserves to create loans that expand spending and demand.

Price deflation is far more likely in the near term. But temporary deflation need not be the terror that central bankers fear, at least if the banking system is recapitalized and if interest rates in the industrial countries fall sharply.

Indeed, the ECB already has been driven onto the defensive by the International Monetary Fund, the OECD, financial market analysts, and Anglo Saxon economists in the wake of feverish discussion of the risk of deflation in the eurozone. But what is the appropriate eurozone inflation rate, given de facto economic stagnation?

Early in that terrible decade, deflation became a reality for nearly all countries and for all of the advanced economies. In the last two years, at least six of the advanced economies and as many as eight have been coping with deflation.

The Commission is supposed to have the last word, thereby ensuring the rules credibility and consistency and it seems to have lost this fight in the first round. One could, of course, argue that the SGP should be scrapped, because austerity makes no sense when the eurozone faces the risk of deflation.

The Fed seems poised to make a similar and possibly even more serious misstep in the current environment. For starters, given ongoing concerns about post crisis vulnerabilities and deflation risk, today s Fed seems likely to find any excuse to prolong its incremental normalization, taking a slower pace than it adopted a decade ago.

The inability of unconventional monetary policies to prevent outright deflation partly reflects the fact that such policies seek to weaken the currency, thereby improving net exports and increasing inflation. This, however, is a zero sum game that merely exports deflation and recession to other economies.

Japan provides good lessons about where the true risks are, as it has been suffering from deflation or near deflation for 14 years. Since 1991, Japan has been mired in what Harvard economist Alvin Hansen, a contemporary of Keynes, once described as secular stagnation.

A five year cumulative 30 deflation in prices and wages in Greece, for example which would mean five years of deepening and socially unacceptable depression even if feasible, this amount of deflation would exacerbate insolvency, given a 30 increase in the real value of debt.

Deflation increases the real (inflation adjusted) debt burden, as well as the real interest rate. Though there is little evidence of the importance of small changes in real interest rates, the effect of even mild deflation on real debt, year after year, can be significant.

The main lesson of the Asian financial crisis or, for that matter, of any financial crisis is that deflation is the ultimate threat to recovery. Because the 1997 crisis was confined to East Asia, China was able to escape deflation after it joined the World Trade Organization.

But now the eurozone seems incapable of escaping near deflation, with little economic growth and prices barely moving upwards.

But that is logically flawed even with deflation, real purchasing power would fall, and the real value of debts would rise (debt deflation), as the real depreciation occurs. More importantly, the exit path would restore growth right away, via nominal and real depreciation, avoiding a decade long depression.

Financial investors soon recognized that risk had been underestimated in some countries, causing interest rates to rise, sometimes to unsustainable levels, as in Greece, Portugal, and Ireland. While the decline in aggregate demand led to reduced imports, the combination of higher interest rates, lower public expenditure, tax increases, and wage deflation boosted unemployment and triggered recession.

For example, a central bank might announce that circumstances during, say, the next two years warrant a doubling of the inflation target from the usual that is, almost never varied annual rate of 2 . Such an approach would reduce the risk of debt deflation, while capping inflation expectations to prevent a damaging surge in prices as recovery takes hold.

The chief will be responsible for risk control of the Fund's investments as a whole in terms of portfolio risk, operational risk and compliance risk, and will plan and perform the oversight of performance measurement, investment risk analysis and operational risk analysis, including risk arising from sub adviser and service provider relationships.

If you have 50 percent deflation, people may increase their volume 30, 40 percent, but they won't keep up with it.

A public debt crisis in Japan (as the combination of recession, deflation, and high deficits drove up the debt GDP ratio).

The main reason for the new dose of transatlantic drift is that the crisis is being experienced differently. America fears deflation
