(2022)
Barry Eichengreen
Ricardo Hausmann
Ugo Panizza
The essence of the article is updating the dynamics of Original Sin.
History of origin the hypothesis – Literature – Measuring –
Drivers of Original Sin – Consequences – Case Studies
Structure of
the article
X emerging markets are burdened by more serious credibility
problems than their advanced-country
X emerging markets display fear of floating
X emerging markets have currency mismatches on national balance
sheet
✓ The central cause of financial EM fragility is the inability of
countries to denominate their foreign obligations in their own
currency. And economic size is only robust correlate of a country’s
ability to borrow abroad in its own currency

Consequences

▪ The increase in the local currency share of Uruguay’s
government debt is part of an explicit strategy put in place
following the country’s 2002 debt crisis
▪ Focused on increasing the weight of peso debt policy have
been successful, but improving monetary credibility, reducing
deposit dollarization, and creating a market for long-term
fixed rate peso debt haven’t
▪ Key pillars of Peru’s approach is sound macroeconomic policies
and de-dollarizing the economy with creating a fixed-income
Case
Studies
market in domestic-currency obligations
▪ But that reserve accumulation comes at a price and “abstinence”
in external borrowing question whether it will further succeed
▪ Non-resident investors tend to hedge their local-currency
exposures using forward contracts with domestic pension
funds taking the other side of the hedge
▪ Colombia has made progress in issuing local-currency bonds,
with good fundamentals driven and aided by its inclusion in
the JPMorgan GB-EM-Global index
▪ The increased participation of foreign investors in local
currency bonds markets required the central to invest in
additional international reserves (costly)
10
▪ The World Bank and other multilateral development banks
could issue bonds denominated in a real (i.e., indexed to
inflation) emerging market currency index and use the proceeds
to extend local currency inflation indexed loans to their clients
For
Policymakers
▪ With specific reference to regional development banks, an
alternative would be to offload the currency risk to funds that
are able to achieve global diversification, for instance by TCX
(The Currency Exchange Fund) hedging
▪ Also the necessary policy response is to strengthen local debt
management capacity, so that debt managers are better
equipped to understand and evaluate the cost/risk tradeoffs of
different borrowing options
«While a forward-looking benevolent policymaker would see that
the premium, when appropriately priced, exactly compensates for
currency risk, and, in the presence of risk aversion, would opt for
the safer local currency debt, myopic policymakers who only care
about the present would disregard negative events that may
materialize when they are no longer in office»
