Building international financial conditions indices

IMF staff has developed global financial conditions indices for 43 global economies. Conceptually, these indices extract the communal component of range of indicators for local financing conditions, independent of economic conditions. The idea looks like a good basic principle for building FCIs for macro trading strategies. The research on these indices suggests that [1] financial conditions are a warning sign for recessions, and [2] global financial shocks have a powerful impact on local conditions, particularly in the short run and in emerging economies.

The global effects of a U.S. term premium shock

Empirical research suggests that shocks to U.S. treasury term premia have had a persistent subsequent impact on term premia in other developed and emerging fixed income markets. Global financial integration and inflation seem to increase the sensitivity of non-U.S. markets. A 200bps rise in the U.S. premium from current compressed levels could boost the term premia in other countries between 50 and 175 basis points. Hence, a U.S. shift towards reflationary policies or greater net supply of long-term treasuries could greatly increase borrowing costs around the world, exposing weaknesses in overleveraged economies and sectors.

Watching U.S. financial conditions

The U.S. financial system wields dominant influence over the national and global economies. Moreover, securities and derivatives markets play a greater role relative to banks and compared to other developed countries. Medium-term shifts in financial conditions, rather than short-term changes, should be consequential for economic growth and monetary policy. Therefore, a timely and consistent measurement of U.S. financial conditions is crucial for macro trading strategies. A broad econometric measure of U.S. financial conditions based on risk, liquidity and leverage is produced and regularly updated by the Chicago Fed.

Nowcasting GDP growth

Financial markets have long struggled with tracking GDP growth trends in a timely and consistent fashion. However, over the past decade statistical methods for “nowcasting” various economies have improved considerably, benefiting macro trading strategies. Dynamic factor models have become the method of choice for this purpose: they extract the communal underlying factor behind timely economic reports and translate the information of many data series into a single underlying trend. The estimation process may look daunting, but its basics are intuitive and calculation is executable in statistical programming language R.

Measuring non-conventional monetary policy surprises

A new paper proposes a measure for monetary policy surprises that arise from asset purchases and forward guidance. The idea is to estimate the change in the first principal component of government bond yields at different maturities to the extent that it is independent of changes in the policy reference rate and on days of significant policy statements. Such identified non-conventional policy shocks have had a persistent impact on yield curves and exchange rates since 2000. Their monitoring is important for so-called “long-long” risk parity trades.
