A well-known puzzle in economics is that when stocks are added to the S&P 500 index, their prices rise. Using a theoretical framework and empirical evidence, this column shows that this ‘benchmark inclusion subsidy’ arises because asset managers have incentives to hold some of the equity of firms in the benchmark regardless of the risk characteristics of these firms. As a result, asset managers effectively subsidise investments by benchmark firms. As the asset management industry continues to grow, the benchmark inclusion subsidy will only get bigger.

In theory, firms in developing countries benefit from viable, well-used, stable, and efficient local financial markets as a source of investment for local firms. Financial markets in the home countries of multinationals can also act as a source of FDI to the developing world when local financial markets are weak. This column discusses recent empirical data that support both arguments, and argues that advocates of tighter regulation for financial markets should consider the wider impact on developing country economies.

The categorisation of countries into relevant international benchmark indices affects the allocation of capital across borders. The reallocation of countries from one index to another affects not only capital flows into and out of that country, but also the countries it shares indices with. This column explains the channels through which international equity and bond market indices affect asset allocations, capital flows, and asset prices across countries. An understanding of these channels is important in preventing a widening share of capital flows being impacted by benchmark effects.

The ECB recently announced a new monetary operation – targeted longer-term refinancing operations, or TLTRO II – that essentially subsidises bank loans to the real economy. This column argues that this ‘cash for loans’ scheme, which might cost up to €24 billion, is unlikely to affect the real economy greatly. This is because banks can easily window dress their loans to qualify. TLTRO II also tests the limits of the ECB’s mandate by stepping into the fiscal policy space.

The carry trade in foreign currency has attracted considerable attention from academics and practitioners. This column presents evidence of a new carry trade strategy – this time speculating on the volatility of foreign exchange. This is done by buying or selling forward volatility agreements. It suggests that investors following the new carry trade can do extremely well – regardless of whether the value of these currencies go up or down.
