The euro crisis has forced member states and the EU institutions to create a series of new instruments to safeguard macro-financial stability of the Union. This study describes the status of existing instruments, the role of the European Parliament and how the use of the instruments impinges on the EU budget also through their effects on national budgets. In addition, it presents a survey of other possible instruments that have been proposed in recent years (e.g. E-bonds and eurobonds), in order to provide an assessment of how EU macro-financial stability assistance could evolve in the future and what could be its impact on EU public finances.

This CEPS Special Report analyses the proposed expansion of innovative financial instruments in the EU Multiannual Financial Framework for the 2014–20 period. It presents the economic rationale, governance principles and criteria that these instruments should follow and compares these with proposals from the European Commission. Based on this assessment, it makes recommendations for the proposed instruments.

A bipolar air conductivity instrument is described for use with a standard disposable meteorological radiosonde package. It is intended to provide electrical measurements at cloud boundaries, where the ratio of the bipolar air conductivities is affected by the presence of charged particles. The sensors are two identical Gerdien-type electrodes, which, through a voltage decay method, measure positive and negative air conductivities simultaneously. Voltage decay provides a thermally stable approach and a novel low current leakage electrometer switch is described which initiates the decay sequence. The radiosonde supplies power and telemetry, as well as measuring simultaneous meteorological data. A test flight using a tethered balloon determined positive (σ+) and negative (σ−) conductivities of σ+ = 2.77±0.2 fS m−1 and σ− = 2.82±0.2 fS m−1, respectively, at 400 m aloft, with σ+/σ− = 0.98±0.04.
