This paper develops a game theoretic model of a 'Buy-or-Sell' auction. Participants have to submit both a bid and an offer price for up to one of the many units of the good being auctioned. The bid-ask spread is set in advance by the auctioneer. Such an auction was used by the Central Bank of Brazil to intervene in the foreign exchange market during the exchange rate crawling-peg regime (1995-1999). I investigate whether such mechanism is more effective than standard intervention auctions to prevent speculative attacks in the context of managed exchange rate regimes.
