Objectives: Is the Economic and Monetary Union (EMU) truly ‘irreversible’ as stated in the treaties? (i) From the sovereign debt crises of the 2010s, and the outbreak of the COVID-19 pandemic, we draw the lesson that when exposed to large, systemic shocks the EMU faces a trilemma among...

This working paper was written by Cho-Hoi Hui (Hong Kong Monetary Authority), Andrew Wong(Hong Kong Monetary Authority) and Chi-Fai Lo (The Chinese University of Hong Kong).This note uses a target-zone model to study the bond yield movements under yield curve control. The bond yield is assumed...

This paper identifies key issues surrounding the advisability and practicality of adopting "target zones" for the exchange rates of major currencies. Pour fundamental questions concerning the definition of and the rationale for target zones are addressed: first, what is generally meant by a...

This paper is a recap of G3 exchange rate relationships since the collapse of Bretton Woods and an analysis of recent proposals for changing the way the G3 countries currently conduct exchange rate policy. We seek to understand these proposals in the context of the status quo monetary policies...

This paper develops a simple econometric procedure for estimating expected exchange rate under target zones. We employ the linear projection methodology to make predictions without relying on any prior structural or distributional assumptions, and at the same time demonstrate that such a...

In the revised monetary policy strategy of the European Central Bank (ECB), "price stability is best maintained by aiming for two per cent inflation over the medium term", with "symmetric commitment" to this target. "Symmetry means that the Governing Council considers negative and positive...

In this paper we develop an empirical model of exchange rates in a target zone. The model is general enough to nest most theoretical and empirical models in the existing literature. We find evidence of two types of jumps in exchange rates. Realignment jumps are those that are associated with the...

This paper examines the recently noted finding that the Classical gold standard represented a credible, well-behaved target zone system from the perspective of the well-documented failure of countries to play by the rules of the game in the classical period. In particular, we test an hypothesis...

With many emerging market currencies tied to the U.S. dollar either implicitly or explicitly, movements in the exchange values of the currencies of major countries have the potential to influence the competitive position of many developing countries. According to some analysts, establishing...

This paper develops a highly simplified model of exchange rate behavior within the band under a target zone regime. It shows that the expectation that authorities will defend the band exerts a stabilizing effect on exchange rate behavior within the band, even when the authorities are not...

Empirical work on exchange-rate behavior under a target-zone regime has used data produced by the European Monetary System (ENS) and has found that the data contradict important predictions made by the standard target-zone model. We argue that the contradictions reflect a misinterpretation of...

The lesson of the sovereign debt crises of the 2010s, and of the outbreak of the COVID-19 pandemic is that EMU irreversibility, if not to remain a wishful statement in the founding treaties, necessitates to be completed by carefully designed ramparts for extraordinary times beside regulations...

The target zone model of Krugman (1991) has failed empirically. In this paper, we develop a model of the exchange rate with heterogeneous agents in a free floating and a target zone regime. We show that this simple model mimics the empirical puzzles of exchange rates: excessive volatility, fat...

In this paper, we analyze the relation between interest rate targets and money supply in a (bubble-free) rational expectations equilibrium of a standard cash-in-advance model. We examine contingent monetary injections aimed to implement interest rate sequences that satisfy interest rate target...

We derive the optimal exchange rate policy for a small open economy subject to terms-of-trade shocks. Firm owners and workers are risk averse but workers more so. Wages are given or partially indexed in the short run, and capital markets are imperfect. The government sets the exchange rate to...

This paper considers what we argue was the first experiment of an exchange rate band. This experiment took place in Austria-Hungary between 1896 and 1914. The rationale for introducing this policy rested on precisely those intuitions that modern target zone literature has recently emphasized:...

We examine the expected survival time of a unilateral exchange rate target zone, when constraints on monetary policy prevent the central bank from exclusively focusing on defending the target zone. Generally, the width of the target zone has a negligible effect on the expected survival time, and...

We discuss the idea of a purely algorithmic universal world iCurrency set forth in: "https://ssrn.com/abstract=2542541" https://ssrn.com/abstract=2542541 and expanded in: "https://ssrn.com/abstract=3059330" https://ssrn.com/abstract=3059330 in light of recent developments, including Libra. Is...

From September 2011 to January 2015, the Swiss National Bank (SNB) implemented a minimum exchange rate regime (i.e. a one-sided target zone) vis-à-vis the euro to fight deflationary pressures in the aftermath of the Great Financial Crisis. During this period of unconventional monetary policy,...

After a market downturn, especially in an uncertain economic environment such as the current state, there can be a relatively long period with a sideways market, where indexes, stocks, etc., move in channels with support and resistance levels. We discuss option pricing in such scenarios, in both...

Lera and Sornette (2016) derive an analytical expression for the conditional volatility of the (unobservable) economic fundamental in Krugman (1991)'s target zone model by locally inverting the relation between the exchange rate and its fundamental value, such that it can be modelled as a...

We study optimal trading in an Almgren-Chriss model with running and terminal inventory costs and general predictive signals about price changes. As a special case, this allows to treat optimal liquidation in “target zone models”: asset prices with a reflecting boundary enforced by...

In this note we discuss - in what is intended to be a pedagogical fashion - FX option pricing in target zones with attainable boundaries. The boundaries must be reflecting. The no-arbitrage requirement implies that the differential (foreign minus domestic) short-rate is not deterministic. When...

This paper develops a new theoretical model with an asymmetric informal one-sided exchange rate target zone, with an application to the Swiss franc following the removal of the minimum exchange rate of CHF 1.20 per euro in January 2015. We extend and generalize the standard target zone model of...

Consider the problem of a central bank that wants to manage the exchange rate between its domestic currency and a foreign one. The central bank can purchase and sell the foreign currency, and each intervention on the exchange market leads to a proportional cost whose instantaneous marginal value...

Starting from the stylized fact that the Swiss franc is a safe haven currency, this paper focuses on the determinants of the Swiss franc during the lower bound regime from September 2011 to January 2015. We describe the Swiss franc as a function of global market risk fundamentals and find that...

I show that parity realignments alone do not suffice to ensure the long-run sustainability of an exchange rate target zone with imperfect credibility due to the gambler's ruin problem. However, low credibility and frequent realignments can destabilize the exchange rate

Currency target zones have been under scrutiny for the past three decades, which led to the development of two broad classes of quantitative models: Phenomenological ones that explicitly take into consideration the market's perception of the bounded exchange rate, and more mechanical ones that...
