• EMs cannot issue Reserve Currencies, • which forces them to painful adjustment if subject to large cut in capital inflows (Sudden Stop).
• Sudden Stops are the Damocles’ sword of EMs,
• and have become more frequent as a result of Financial GlobalizaGon.
• Crises: Tequila (1994/5), Asia/Russia (1997/8), Dotcom (2001/2), Lehman (2008) ...

Systemic Crises • These crises have been systemic and costly. • From the perspecGve of most individual EMs, these crises stem from external factors.
• The importance of external factors in LaGn America has been widely documented.
• This does not imply that EMs can do nothing to assuage the impact of these crises.
• Research and policy experience show that EMs can resort to a variety of effec6ve—but not fully effec6ve—precau6onary measures.
![Page 5: Monetary Challenges in Emerging Markets Guillermo Ca… · Monetary Challenges in Emerging Markets Guillermo Calvo Columbia University Biennial Conference 2016, South African Reserve](https://reader034.fdocuments.net/reader034/viewer/2022042406/5f208382e168df10437c31ed/html5/thumbnails/5.jpg)
Research Findings
• Systemic crises have a large random component, which is due to the existence of self-‐fulfilling prophesies. (Will Brexit give rise to systemic crisis?)
• However, we have found some robust regulariGes linking the probability of SS for individual economies condiGonal on systemic crisis.
![Page 6: Monetary Challenges in Emerging Markets Guillermo Ca… · Monetary Challenges in Emerging Markets Guillermo Calvo Columbia University Biennial Conference 2016, South African Reserve](https://reader034.fdocuments.net/reader034/viewer/2022042406/5f208382e168df10437c31ed/html5/thumbnails/6.jpg)
SS condi6onal on Systemic Crisis
Calvo, Izquierdo, Mejía (2008 revised in Calvo 2016) claims that the probability of SS for an individual country increases as a funcGon of: • Current Account Deficit • Mismatch of currency denominaGon between LiabiliGes and Assets, especially if the mismatch takes place in the domesGc banking system (labeled DLD, DomesGc Liability DollarizaGon).
![Page 7: Monetary Challenges in Emerging Markets Guillermo Ca… · Monetary Challenges in Emerging Markets Guillermo Calvo Columbia University Biennial Conference 2016, South African Reserve](https://reader034.fdocuments.net/reader034/viewer/2022042406/5f208382e168df10437c31ed/html5/thumbnails/7.jpg)
Interna6onal Reserves • DLD implies that the probability of condiGonal SS declines with the stock of InternaGonal Reserves.
• This is discussed in Calvo, Izquierdo, Loo-‐Kung (2013).
• This methodology suggests that South Africa exhibited a shorcall of InternaGonal Reserves in 2010.
• Issue seems to persist. The 2016 ArGcle IV states: “Directors encouraged authoriGes to seize opportuniGes to increase reserves.”

Floa6ng and Reserves • Why should “floaters” hold IReserves? • A key reason is that Interna6onal transac6ons must be seCled in terms of reserve-‐currency liquid instruments (USD, €, ¥).
• Absence of IReserves may exacerbate exchange rate vola6lity, and seriously interfere with financial transac6ons and trade.
• This helps to explain why Calvo et al (2013) empirical results show that “floa6ng” has no impact on op6mal IReserves holding.

• In 1998, EMs were len on their own. • No internaGonal Lender of Last of Resort, LOLR, came to their rescue.
• In contrast, in the Lehman episode the Fed, BOE, ECB, BOJ, went out in force.
• These natural experiments suggest that there is an important role for a Global LOLR in shielding EMs from Systemic Sudden Stop.

Advanced Economies: Running out of Ammo?
• Advanced economies, AEs, are slowly and hesitantly coming out of recession.
• DeflaGon is a constant threat. • Credit Sudden Stop has been and s6ll is a major factor in AEs slump.
• But AE central banks keep pulling at the usual levers, – now with a trembling hand because QE and negaGve interest rates are “unconvenGonal”, although for me they look more of the same.
![Page 22: Monetary Challenges in Emerging Markets Guillermo Ca… · Monetary Challenges in Emerging Markets Guillermo Calvo Columbia University Biennial Conference 2016, South African Reserve](https://reader034.fdocuments.net/reader034/viewer/2022042406/5f208382e168df10437c31ed/html5/thumbnails/22.jpg)

HERE IS WHERE CENTRAL PROBLEM LIES !!
![Page 25: Monetary Challenges in Emerging Markets Guillermo Ca… · Monetary Challenges in Emerging Markets Guillermo Calvo Columbia University Biennial Conference 2016, South African Reserve](https://reader034.fdocuments.net/reader034/viewer/2022042406/5f208382e168df10437c31ed/html5/thumbnails/25.jpg)
EMs and AE Low Interest Rates
• The iniGal easy-‐money AE policy helped quick recovery in EMs.
• However, low AE interest rates are a concern, especially as the US seems on its way to keep raising the Federal Funds rate.
• The 2013 “Taper Tantrum” is a natural experiment that suggests that further hike of Fed rates may wreak chaos in EMs.
![Page 26: Monetary Challenges in Emerging Markets Guillermo Ca… · Monetary Challenges in Emerging Markets Guillermo Calvo Columbia University Biennial Conference 2016, South African Reserve](https://reader034.fdocuments.net/reader034/viewer/2022042406/5f208382e168df10437c31ed/html5/thumbnails/26.jpg)
MACROPRU • Given these condiGons, IReserves acquires further relevance.
• But, in addiGon, the government should go through “crisis drills” to ensure effec6ve use of IReserves, and not become just outlets for Capital Flight.
• Keep an eye on banks’ wholesale funding, and non-‐bank intermediaries (e.g., auto retailers). – The associated liabiliGes are much quicker to suffer a run than convenGonal bank deposits.
![Page 27: Monetary Challenges in Emerging Markets Guillermo Ca… · Monetary Challenges in Emerging Markets Guillermo Calvo Columbia University Biennial Conference 2016, South African Reserve](https://reader034.fdocuments.net/reader034/viewer/2022042406/5f208382e168df10437c31ed/html5/thumbnails/27.jpg)
EM Monetary Policy
• There are pracGcally no “pure floaters.” • Not even the US or EU are pure floaters if you take into account Currency Swaps.
• The USD is the Sun. All other currencies are satellites.
• Especially EM currencies. • Therefore, EM central banks keep a close eye to the USD exchange rate.
![Page 28: Monetary Challenges in Emerging Markets Guillermo Ca… · Monetary Challenges in Emerging Markets Guillermo Calvo Columbia University Biennial Conference 2016, South African Reserve](https://reader034.fdocuments.net/reader034/viewer/2022042406/5f208382e168df10437c31ed/html5/thumbnails/28.jpg)
• In the 1980s and 1980s, Exchange Rate Based StabilizaGon programs were in vogue, but many failed.
• Nowadays, InflaGon TargeGng is in vogue, and it may be berer because E has a weak link with the P, which is more relevant than E for wage negoGaGons.
• The instrument of choice is i. • However, i has a weak link with P if:
– domesGc capital market is shallow – credibility is low.
![Page 29: Monetary Challenges in Emerging Markets Guillermo Ca… · Monetary Challenges in Emerging Markets Guillermo Calvo Columbia University Biennial Conference 2016, South African Reserve](https://reader034.fdocuments.net/reader034/viewer/2022042406/5f208382e168df10437c31ed/html5/thumbnails/29.jpg)
• Unfortunately, the larer may give rise to unwanted effects (unemployment, appreciaGon of the real exchange rate), and undermine credibility.
• Thus, it is common for central banks to resort to exchange rate interven6on when the laCer gets off track, even in absence of terms-‐of-‐trade shocks menGoned at the start.
• Borom Line: Dirty floa6ng dominates, which, among other things, militates against trade among EMs.
