Is maintaing forex reserves enough?

February 18, 2010

Joshua Aizenman of UCSD has written a useful paper on Korean economy’s experience in this crisis. 

In this paper we explore lessons from the current global liquidity crisis pertaining to the prudential supervision role of central bank in an open economy. The crisis validates the need for external debt management policy in emerging markets. Hoarding international reserves (IR) is a potent self-insurance mechanism. However, it is associated with relatively high costs and is also less efficient in absence of assertive external debt management policies. In the presence of firesale externalities associated with deleveraging, optimal external borrowing-tax-cum-IRhoarding-subsidy reduces the cost as well as the scale of hoarding IR.

 In nut shell he says despite having large forex reserves, Korean economy could not prevent exchange rate pressures. Why? Because it had large short term external debt.

Less than ten years after the 1997-8 East Asian crisis, Korea’s IR/GDP ratio seemed more than adequate by conventional yardsticks. Indeed, observers have been raising questions about the growing costs of stockpiling these reserves. It was asserted that the level of IR in EMs, including Korea, potentially exceed the social optimum [see Jeanne and Ranciere (2005)].

 Having said this, the sense of blissful abundance of IR in Korea evaporated following the sizable increase in Korea’s external debt during 2005-2008. The Korean external short term debt/GDP ratio increased from 7.5% in 2004 to 20% in 2008, while the overall external debt/GDP ratio increased during that period from 23% to 50%, without any significant change in IR/GDP. ‘

 This drastic increase has been attributed to several factors, including exposure to short term inflows of Less than ten years after the 1997-8 East Asian crisis, Korea’s IR/GDP ratio seemed more than adequate by conventional yardsticks. Indeed, observers have been raising questions about the growing costs of stockpiling these reserves. It was asserted that the level of IR in EMs, including Korea, potentially exceed the social optimum [see Jeanne and Ranciere (2005)].

 The forex reserves which were seen as insurance mechanism were considered inadequate. Moreover, emerging economies central banks were scared not to let the reserves slip below a certain %. They were afraid that markets would take that as a negative signal and lead to further speculation. In Korea’s case till swap line with Fed was not set., things looked bad.

 

Interesting lessons for emerging economies. You need to watch everything and be on toes. The external debt indicators should always be looked at.

Spot the fiscal deficit peacock!

February 18, 2010

Paul Krugman points to a Martin Wolf article. Wolf basically says that deficit hysteria is overblown and US is not Greece. Wolf in turn bases his article on Niall Ferguson who has been raising deficit concerns for a while.

In the end Wolf says:

So, yes, high-income countries face huge fiscal challenges. And yes, the crisis-hit countries start from grossly unsustainable fiscal positions. But the US is not Greece. Moreover, a massive fiscal tightening today would be a grave error. There is a huge risk – in my view, a certainty – that this would tip much of the world back into recession. The private sector must heal. That, not fiscal retrenchment, is the priority.

Hmm. We will only know in future how things shape up. Who could have thought US would be in such bad shape in 2007?

Anyways, now to the title of the post. Krugman points to this excellent article by Michael Linden of American Progress.  Linden tells you how to spot a deficit peacock. Unlike a deficit hawk who is serious about cutting deficits, peacock just talks fancy and is pretends to be a deficit hawk. Krugman says most are actually deficit peacocks.

Who is a deficit peacock?

Eleven lessons from Iceland

February 18, 2010

Thorvaldur Gylfason. Professor of Economics at University of Iceland has summarised 11 lessons to be learnt from Iceland.

A number of economists have discussed the consequences of Iceland’s troubles and suggested solutions (Buiter and Sibert 2008, Danielsson 2010), but a key question remains: How could this happen?

To make a long story short (for the longer story, see Gylfason et al. 2010), the absence of checks and balances that had led to an unbalanced division of power between the strong executive branch and the much weaker legislative and judicial branches came to haunt the country when unscrupulous politicians put the new banks in the hands of reckless owners who then found themselves in a position to expand their balance sheets as if there were no tomorrow – and no supervision. Politicians who privatise banks by delivering them on a silver plate to their friends are not very likely to subject the banks to stringent supervision or other such inconveniences.

Iceland’s predicament raises old questions about collective guilt and responsibility. Many wonder how taxpayers can be held responsible for the failures of private bankers. But taxpayers are also voters – many of them voted for the politicians who sided with the bankers, having abstained or voted for the opposition is clearly not a valid excuse. Guilty or not, many feel responsible as taxpayers, but not all.

One year of of fiscal stimulus

February 18, 2010

Menzie Chinn reviews one year of fiscal stimulus. He looks at many studies and articles looking at growth, unemployment etc with and without stimulus. Majority of the studies show  stimulus worked….. barring works of John Taylor and Robert Barro.

So Chinn says:

So, in order to make their case, critics who argue that the stimulus package passed a year ago had no positive impact on GDP need to either (1) explain why the commercial forecasters are incorrect in their assessments, (2) why the CBO is similarly misguided, or (3) why their preferred models are superior to the alternative approaches in this context (demonstrating, along the way, their superior predictive power). Until that occurs, I’ll stick with the mainstream. (Caveat: I freely admit I have no access to the simulations from the Fed’s DSGEs, which would also be in what I consider “the mainstream”.)

The debate will continue for a very long time.
