This paper examines the impact of central bank communication on market expectations of monetary policy and long-term interest rates by comparing Federal Open Market Committee (FOMC) action dates when a policy statement was made to dates before statements were issued. Increased communication has been associated with a reduction in the magnitude of short-term monetary surprises; a greater flow of information about the long-term path of policy that is distinct from the short-term surprise; and a larger role for these long-term surprises in the determination of long-term interest rates.
This paper examines the role of the derivatives market in South Africa and provides policy options for promoting the development of derivatives markets in sub-Saharan Africa. South Africa's derivatives market has grown rapidly in recent years, supporting capital inflows and helping market participants to price, unbundle and transfer risk. There are tight regulations on asset allocations by insurance and pension funds to prevent excessive risk taking. The development of derivatives markets in sub-Saharan African countries could enable market participants to self-insure against volatile capital flows. Theiroverdependence on bank credit as a source of funding could be reduced and their management of seasonal risk could be improved through the introduction of commodity futures. However, these markets must be appropriately regulated and supervised. Since such markets would likely be small, consideration should be given to the establishment of a regional derivatives market.
This paper studies the relative effectiveness of foreign exchange intervention in spot and derivatives markets. We make use of Brazilian data where spot and non-deliverable futures based intervention have been used in tandem for more than a decade. The analysis finds evidence in favor of a significant link between both modes of intervention and the first two moments of the real/dollar exchange rate. As predicted by theory for the case of negligible convertibility risk, the impact of spot market intervention in our baseline sample is strikingly similar to that achieved through futures based intervention worth an equivalent amount in notional principal.

Changes in the structure of the U.S. Treasury market over recent years may have increased risks to financial stability. Traditional market makers have changed their liquidity provision by increasingly switching from risk warehousing to risk distribution, and a new breed of market maker has emerged with the rise of electronic trading. The “flash rally” of October 15, 2014 provides a clear example of how those risks can materialize. Based on an in-depth analysis of the event—complementing the authorities’ work—we suggest i) providing incentives for liquidity provision, ii) improving market safeguards, and iii) enhancing the regulation of the Treasury market.
A common specification about the behavior of foreign exchange spot and futures prices is that they follow continuous diffusion processes. The empirical regularities uncovered from daily and weekly currency futures data, however, cast doubts on the validity of this model. First, contrary to the suggestions in the literature, changes in foreign currency futures prices are serially correlated; variance ratio tests and other related tests overwhelmingly reject Samuelson’s martingale hypothesis. Second, foreign exchange futures prices do not appear to have continuous sample path; the evidence suggests the presence of a jump component, which may lead to pricing bias when applying the standard Black-Scholes option pricing formula to foreign exchange markets.
Building on the widely-used double-lognormal approach by Bahra (1997), this paper presents a multi-lognormal approach with restrictions to extract risk-neutral probability density functions (RNPs) for various asset classes. The contributions are twofold: first, on the technical side, the paper proposes useful transformation/restrictions to Bahra’s original formulation for achieving economically sensible outcomes. In addition, the paper compares the statistical properties of the estimated RNPs among major asset classes, including commodities, the S&P 500, the dollar/euro exchange rate, and the US 10-year Treasury Note. Finally, a Monte Carlo study suggests that the multi-lognormal approach outperforms the double-lognormal approach.
