While the euro area ponders another round of quantitative easing, Poland's monetary policy remains stubbornly conventional. Although the NBP's Monetary Policy Council has delivered a monetary easing cycle, policy rates in Poland remain above those of many peers, most notably the largest trading...

This paper investigates the changes in the investment portfolio performance after including VIX. We apply different models for optimal portfolio selection (Markowitz and Black-Litterman) assuming both the possibility of short sale and the lack of it. We also use various assets, data frequencies,...

The article presents a simple parameterization of the volatility surface for options on the S&P 500 volatility index, VIX. Specifically, we document the following features of VIX implied volatility: (i) VIX at-the-money (ATM) implied volatility correlates strongly with the volatility skew in S&P...

The adjustment speed of delta hedged options exposure depends on the market realized and implied volatility. We observe that by consistently hedging long and short positions in options we can eventually end up with pure exposure to volatility without any options in the portfolio at all. The...

We suggest that the term structure of volatility futures (e.g. VIX futures) shows a clear pattern of dependence on the current level of VIX index. At the low level of VIX (below 20) the term structure is highly upward sloping; at the high VIX level (over 30) it is strongly downward sloping. We...

The banking system is modeled in a closed system of financial accounts, whereby the equilibrium volume of bank intermediation between households and corporates reflects structural parameters such as household preferences, comparative cost structures of heterogeneous banks, loan demand of...

We suggest that the term structure of VIX futures shows a clear pattern of dependence on the current level of VIX index. At the low levels of VIX (below 20), the term structure is highly upward sloping, while at the high VIX levels (over 30) it is strongly downward sloping. We use these features...

In the liquidity crises since 2008, central banks have extended the ability of banks to take recourse to central bank credit operations through changes of the collateral framework. Remarkably, in March 2020, the ECB even lowered haircuts across a broad range of assets and the Fed in March 2023...

The paper attempts to investigate the influence of the 1988 Basel Accord on bank behavior and monetary policy. It is argued that the Accord was successful in that it forced commercial banks in all of G-10 countries to maintain higher capital ratios. Tentative research suggests, however, that –...
