Iceland's krona: From amplifier to shock absorber
Þórarinn G. Pétursson, Deputy Governor of Monetary Policy, explained how Iceland's krona transformed from amplifying economic shocks to absorbing them. Speaking at the Reykjavik Economic Conference, he attributed this shift to post-crisis reforms and stronger fundamentals.
Krona's pre-crisis amplification
Prior to the Global Financial Crisis, Iceland's krona acted as a shock amplifier.
Following the adoption of inflation targeting in 2001, the economy saw a credit boom, widespread foreign currency borrowing, and a current account deficit reaching 25% of GDP.
This overheating culminated in a sudden stop of capital inflows, leading to a nearly 50% depreciation of the krona.
The sharp currency decline devastated domestic balance sheets and contributed to the collapse of the banking system, illustrating how exchange rate variability can amplify shocks rather than absorb them.
This experience highlighted the vulnerabilities of a small open economy with significant foreign currency exposure and weak policy frameworks.
Reforms enable shock absorption
Post-GFC, Iceland undertook comprehensive reforms to strengthen its macroeconomic fundamentals.
Key measures included significantly reducing external imbalances, limiting foreign currency balance sheet exposure, and boosting foreign exchange reserves to 20% of GDP.
Policy frameworks were enhanced with a Monetary Policy Committee and expanded tools, such as FX interventions and macroprudential measures.
These reforms transformed the krona's behavior, allowing it to consistently act as a buffer during subsequent external shocks.
Empirical evidence supports this, showing that post-GFC krona fluctuations are now predominantly driven by real demand and supply shocks, with its correlation to the output gap rising from 30% to 65%.
From vulnerability to resilience
The Icelandic experience offers a compelling case study for small open economies on managing exchange rate volatility.
It underscores that robust macroeconomic fundamentals and strong policy frameworks are crucial for a currency to act as a shock absorber, not an amplifier.
However, the inherent challenges of managing a small currency persist, demanding continuous vigilance from the central bank.
