But this overlooked a crucial feature of monetary unions free capital mobility and elimination of currency risk indispensable attributes of a currency area could be (and were) the source of asymmetric shocks. Currency unions, in other words, must worry about endogenous as much as exogenous shocks.

Conscious of the volatility of the currency exchange markets and the significant risk that unanticipated exchange rate changes have on operations, management will continue to assess and manage the risks posed by volatile currency fluctuations.

In the first scenario, a more united and homogeneous Europe emerges from the crisis, enforcing greater restrictions on member states budgets to reduce apparent risk. Accompanied by a strong, broad eurozone, risk of a future currency crisis remains.

To believe that any country issuing debt in its own currency is risk free as long as the exchange rate is flexible is astonishingly naive. For one thing, there is still inflation risk, particularly for countries with weak fiscal institutions and heavy debt burdens.

Some of the ideas discussed during the consultations include suggestions for mechanisms to mitigate regulatory risk to increase the role of the World Bank and regional development banks in risk mitigation through increasing the leverage for their guarantees and to strengthen local currency lending.

The final key risk facing the world concerns currency. Since the global economic crisis, the expansionary monetary policies that advanced economy central banks have pursued have caused large scale, volatile capital flows across emerging economy borders, generating significant instability for these countries and fueling accusations of currency wars.

Such price increases can prove particularly inflationary in countries that import commodities. And they can be disastrous to exporting economies, which risk rapid currency appreciation and thus a loss of competitiveness.

Ownership of currency is generally proven through possession of the currency.

The second condition for broad based currency depreciation is financial markets' willingness to assume and maintain risk postures that are not yet validated by the economy's fundamentals. With central banks the de facto best friend of financial markets these days pushing for increasingly large financial risk taking (as a means of stimulating productive economic risk taking), this is no easy feat.

But fiscal stimulus is constrained within the eurozone, where member countries no longer issue their own currency and sovereign debt therefore carries a default risk. Aggressive monetary expansion through quantitative easing is also far more complicated and politically contentious in a currency area with no federal debt for the central bank to buy.

Conventional wisdom also once held that dollar borrowing binges occur only in countries with fixed exchange rates, with the central bank de facto insuring borrowers against currency risk. Today, most emerging market economies have (or at least pretend to have) floating exchange rates, and yet locals continue to borrow heavily in foreign currency.

Later writers came to recognize that there are other essential criteria for a successful currency union, which are difficult to achieve without deep political integration. Peter Kenen argued in the late 1960 s that without exchange rate movements as a shock absorber, a currency union requires fiscal transfers as a way to share risk.

The fear is that neither Japan s subsequent actions nor the affected countries domestic realities will justify the risk of lost market share, especially at a time when the global economy as a whole and global policy coordination is struggling. Here the risk involves currency wars and other beggar thy neighbor disruptions.

The performance analysis will comprise an attribution analysis, to determine the driving forces behind investment performance of each manager, a returns analysis, and risk statistics related to each investment manager, sector, industry, currency and region.

A sixth option especially where a country has carried out partially sterilized intervention to prevent excessive currency appreciation is to reduce the risk of credit and asset bubbles by imposing prudential supervision of the financial system. This should be aimed at restraining excessive credit growth, which the monetary growth that follows currency intervention would otherwise cause.

By creating the European Central Bank, the member states exposed their own government bonds to the risk of default. Developed countries that issue bonds in their own currency never default, because they can always print money.

A deeper and more efficient financial sector would also reduce transaction costs and facilitate risk management. Local currency bond markets could help to develop domestic investor bases and mobilize domestic savings to support long term investments.

Jaroslaw Kaczynski is an intelligent politician who understands the link between currency stability and political success. So he will not allow government largesse to become excessive and thus risk a negative reaction in the financial markets.

In the early 1990 s, policymakers, market participants, and economists alike simply assumed that the European Community s 1992 program the legislative framework for the single market, and thus for a single capital market would create a new reality, within which the single currency would work its magic. From this followed an official obligation to treat all types of risk in the monetary union bank risk or government risk as identical.

Second, because the dollar is used as a reserve currency, a rapid rise in its value could put pressure on those who have used it imprudently. At particular risk are emerging country companies that, having borrowed overwhelmingly in dollars but generating only limited dollar earnings, might have large currency mismatches in their assets and liabilities or their incomes and expenditures.

Leaving the common currency would, of course, threaten collateral damage for the exiting country and raise the risk of contagion for other weak eurozone members. The balance sheet effects on euro debts caused by the depreciation of the new national currency would thus have to be handled through an orderly and negotiated conversion of euro liabilities into the new national currencies.

As a default would demand a change in the currency involved in private contracts, business partners from other EU countries would surely sue, legal uncertainties would drag on and on, and an exiting country s trade with its main trading partners would be impaired for years to come. So none of the countries at risk would seriously consider reintroducing a national currency.

Tensions in financial markets have hit new highs. Most telling is that Britain, which retained control of its currency, enjoys the lowest yields in its history, while the risk premium on Spanish bonds is at a new high.

China s government decides that it cannot risk further strife and announces a package of measures to boost economic growth and prevent layoffs, including direct financial support for exporters and intervention in the currency markets to weaken the renminbi.
