This paper investigates the intraday effects of unannounced foreign exchange intervention on bid-ask exchange rate spreads using official intraday intervention data provided by the Danish central bank. Our starting point is a simple theoretical model of the bid-ask spread which we use to...

We investigate the relation between foreign exchange (FX) order flow and the forward bias. We outline a decomposition of the forward bias according to which a negative correlation between interest rate differentials and order flow creates a time-varying risk premium consistent with that bias....

This paper provides real-time evidence on the frequency, size and duration of arbitrage opportunities and deviations from the law of one price (LOP) in the foreign exchange market. We investigate deviations from the covered interest rate parity (CIP) condition ('round-trip arbitrage') and...

This paper investigates the validity of the law of one price (LOP) in international financial markets by examining the frequency, size and duration of inter-market price differentials for borrowing and lending services (`one-way arbitrage'). Using a unique data set for three major capital and...

Using ten years of FX transactions data we demonstrate that a large share of the FX forward discount bias can be accounted for by order flow. A simple microstructure-based decomposition suggests that order flow creates a timevarying risk premium that is correlated with the forward discount. The...

This paper analyzes alternative models for emerging sovereign ratings. Although a small number of economic fundamentals explain ratings reasonably well, variations in those economic fundamentals are themselves explained by a small number of world factors. On the other hand, global financial...

If rating agencies add no new information to markets, their actions are not a public policy concern. But as rating changes may be anticipated, testing whether ratings add value is not straightforward. This paper argues that ratings and spreads are both noisy signals of fundamentals and suggest...

This paper analyses one of the main pillars of Brazil.s newly found economic resilience: a maturing FX market providing support to its managed .oating exchange rate regime. I develop a microstrucure model suitable to describe the Brazilian FX market, an emerging economy frequently subjected to...

This paper examines spillover and spillback effects of unconventional monetary policies conducted by the European Central Bank (ECB) and Swiss National Bank (SNB) on the exchange rate's distribution. The empirical setup examines the price response of EURCHF risk reversal to a change in ECB and...

We document stylized facts about China's recent exchange rate policy for its currency, the renminbi (RMB). Our empirical findings suggest that a "two-pillar policy" is in place, aiming to balance RMB index stability and exchange rate flexibility. We then develop a tractable no-arbitrage model of...
