【摘要】:隨著低碳經(jīng)濟(jì)的興起和碳排放貿(mào)易市場(chǎng)的迅速發(fā)展,碳金融逐漸成為世界各國(guó)可持續(xù)發(fā)展重要的戰(zhàn)略選擇。服務(wù)于碳排放貿(mào)易的碳金融業(yè)務(wù)蘊(yùn)涵著巨大商機(jī),潛在的商機(jī)和踐行企業(yè)社會(huì)責(zé)任的需要使得以商業(yè)銀行為代表的金融機(jī)構(gòu)逐漸涉足碳金融領(lǐng)域。當(dāng)碳金融市場(chǎng)出現(xiàn)劇烈波動(dòng)時(shí),,風(fēng)險(xiǎn)也會(huì)隨之產(chǎn)生。對(duì)于從事碳金融業(yè)務(wù)的金融機(jī)構(gòu)而言,國(guó)際碳價(jià)格的波動(dòng)以及交易結(jié)算過(guò)程中的匯率波動(dòng)都是不可忽視的市場(chǎng)風(fēng)險(xiǎn)因子。 首先,確定了碳金融市場(chǎng)風(fēng)險(xiǎn)的兩個(gè)風(fēng)險(xiǎn)因子:碳價(jià)格波動(dòng)風(fēng)險(xiǎn)和匯率風(fēng)險(xiǎn)。然后,運(yùn)用ARMA-GARCH模型來(lái)刻畫碳價(jià)格波動(dòng)風(fēng)險(xiǎn)和匯率風(fēng)險(xiǎn)收益率序列的邊緣分布,通過(guò)構(gòu)建ARMA-GARCH邊緣分布來(lái)獲取碳價(jià)格波動(dòng)風(fēng)險(xiǎn)和匯率風(fēng)險(xiǎn)收益率序列的標(biāo)準(zhǔn)化殘差序列,采用Copula函數(shù)對(duì)所得到的標(biāo)準(zhǔn)化殘差序列進(jìn)行建模,構(gòu)建出Copula-ARMA-GARCH的相關(guān)結(jié)構(gòu)模型,選擇最優(yōu)擬合的Copula函數(shù),構(gòu)建碳價(jià)格波動(dòng)風(fēng)險(xiǎn)和匯率風(fēng)險(xiǎn)的市場(chǎng)風(fēng)險(xiǎn)整合風(fēng)險(xiǎn)。最后,運(yùn)用Monte Carlo模擬方法計(jì)算出碳金融市場(chǎng)風(fēng)險(xiǎn)整合風(fēng)險(xiǎn)的風(fēng)險(xiǎn)價(jià)值VaR,并在此基礎(chǔ)上進(jìn)行了實(shí)證研究。 通過(guò)實(shí)證得到的結(jié)論是:不考慮碳金融市場(chǎng)風(fēng)險(xiǎn)不同風(fēng)險(xiǎn)因子之間的實(shí)際相關(guān)性會(huì)高估碳金融市場(chǎng)風(fēng)險(xiǎn)的整合風(fēng)險(xiǎn);在相同的置信度下,隨著碳價(jià)格波動(dòng)風(fēng)險(xiǎn)資產(chǎn)比例的增加,整合風(fēng)險(xiǎn)價(jià)值也在不斷的增加;在相同數(shù)量的資產(chǎn)下,潛在的碳價(jià)格波動(dòng)風(fēng)險(xiǎn)大于匯率風(fēng)險(xiǎn)。
[Abstract]:With the rise of low-carbon economy and the rapid development of carbon emissions trading market, carbon finance has gradually become an important strategic choice for the sustainable development of countries in the world. The potential business opportunities and the need to practice corporate social responsibility make the financial institutions represented by commercial banks gradually step into the carbon finance field. For financial institutions engaged in carbon finance, the fluctuation of international carbon price and the fluctuation of exchange rate in the course of trading and settlement are all the market risk factors that can not be ignored. Firstly, two risk factors of carbon financial market risk are determined: carbon price volatility risk and exchange rate risk. ARMA-GARCH model is used to describe the marginal distribution of carbon price volatility risk and exchange rate risk return series. The standardized residuals of carbon price volatility risk and exchange rate risk return series are obtained by constructing ARMA-GARCH edge distribution. The standardized residual sequence is modeled by Copula function, and the related structure model of Copula-ARMA-GARCH is constructed. Select the optimal fitting Copula function to construct the market risk integration risk of carbon price volatility risk and exchange rate risk. Finally. The Monte Carlo simulation method is used to calculate the risk value of the risk integration risk in the carbon financial market, and an empirical study is carried out on this basis. The conclusion is that the integration risk of carbon financial market risk will be overestimated if the actual correlation among different risk factors is not considered; Under the same confidence level, with the increase of carbon price volatility risk asset ratio, the integration risk value is also increasing; Under the same number of assets, the potential carbon price volatility risk is greater than the exchange rate risk.
