On 6 September 2011, a ceiling on the value of the Swiss franc was imposed, at CHF 1.2 per euro. With the continuous weakness of the euro area economy, this exchange rate limit was abandoned on 15 January 2015. This paper proposes a quasi-bounded process for the Swiss franc exchange rate...

This paper proposes a quasi-bounded process for exchange rate dynamics within a target zone, consistent with a credible exchange rate band in which the exchange rate cannot breach the strong-side limit while the weak-side limit is only accessible under restricted conditions of the relationship...

By applying the Lie-Trotter operator splitting method and the idea of the WKB method, we have developed a simple, accurate and efficient analytical approximation for pricing the constant elasticity of variance (CEV) spread options. The derived option price formula bears a striking resemblance to...

While the US dollar and Japanese yen are considered as safe-haven currencies, both their sovereign credit default swap (CDS) spreads and exchange rate have varied in a wide range since late 2007. This raises the question of interconnectivity between the anticipated sovereign credit risk and the...

Under the framework of Basel II, banks which adopt the internal ratings-based approach will be required to compare their actual provisions with expected losses. Any shortfall (i.e., the expected loss exceeds the provision) should be deducted from capital of the bank. It is therefore important to...

The empirical results show that after the introduction of the three refinements to the Linked Exchange Rate system in May 2005 the Hong Kong dollar follows a bounded process that is consistent with a fully credible exchange rate band. The bounded process will limit the movements of the exchange...

Residential mortgage rates in Hong Kong have fallen to a historic low level since late 2004, largely because of severe competition and the prevailing exceptionally low funding cost of the banks. Because of the abundance of liquidity in the banking system, HIBOR is at an abnormally deep discount...
