This study describes the two main economic processes observed in Russia during President Vladimir Putin's second term; renationalisation, and the concentration of economic assets. As a result of these processes, the share of state-owned property has increased and the position of the state in the economy has strengthened. According to the authorities, the wide-range renationalisation of the assets and the construction of superholdings based on the state enterprises are intended to boost Russia's potential and stimulate the development of the whole economy. However, in practice the current ruling elite are using these superholdings to strengthen Russia's position on the international arena and to promote their vested interests.

Quantitative easing à la ECB has produced so far an impact on long-term nominal rates through ex ante channels: signalling channels, term duration channels, and risk premia channels. The term duration channel will also lead to a lengthening of the average maturity of government debts, with possible implications for fiscal policy. The ECB’s determination to buy government bonds in a fragmented market with a low net supply may also produce an ex post impact, during the actual asset purchases, but less on nominal rates and more on financial plumbing, as recent volatility suggests. As the effects of scarce supply in collateral markets are felt, repo rates remain well below zero. Lower supply and limited re-usability of high quality collateral, capped by regulatory requirements, is a constraint on market liquidity and compresses dealers’ balance sheets. By keeping a depressed yield curve and asset prices high, QE may also accelerate the consolidation of both traditional and capital-market based (dealer) bank business models. What is less clear is how these changing business models will interact with the sharp rise of the asset management industry in the aftermath of the crisis, which raises questions about the implications for global collateral flows and deposit-like funding channels.

Secondary carbonate minerals were recovered within the basalts at both ODP Sites 768 and 770 in the Sulu and Celebes seas. Petrographic and X-ray diffraction analyses indicate that the carbonates are calcites. Other alteration products recognized in the thin sections are smectites, iron oxides, and gypsum. The 13C values of carbonates from both sites range from 1.6 per mil to 2.3 per mil, which are indicative of inorganic carbonate formation with no contributions from 13C-depleted sources such as oxidized organic carbon or methane. The oxygen isotopes at Site 770 range from 30.8 per mil to 31.6 per mil, which indicates a pervasive circulation of cold seawater (9° to 12°C) during alteration of the Celebes Sea basalts. In contrast, carbonates associated with Site 768 basalts have less positive d18O values (21.0 per mil to 27.3 per mil). A lighter 18O isotopic signature indicates the formation of secondary calcite at either higher temperatures or in a system closed to seawater. The rapidly deposited pyroclastic flows at Site 768 would have limited water access to the crust very soon after its formation, which leads us to speculate that the carbonates in the Sulu Sea basalts were formed by isotopically modified fluids resulting from basalt alteration in a closed system.
