Asia Currency Risk Disperses but Contagion Channels Expand

The Japanese yen accounts for 14.74% of modelled regional risk. This figure is up from 7.52% in the prior period. Asia’s currency markets are more connected than ever. Risk no longer concentrates in a single crisis point. Disturbances travel through a denser network of relationships. Central banks face a complex surveillance challenge.

A recent study by Corvinus University researchers analyzes this shift. They compare data from 1994 to 2000 with data from 2018 to 2025. The findings show a change in vulnerability form. The yen remains a primary transmitter of shocks. Other currencies absorb these pressures. Domestic safeguards must account for external connections. GN markets/fx (en-US) reports on these structural changes.

Risk dispersion masks systemic exposure

During the 1997 crisis, the Thai baht drove 72.14% of systemic risk. The Indonesian rupiah followed as a major contributor. These were sharp concentrations of financial stress. The recent period shows a broader distribution. The concentration index is substantially lower. No single currency dominates the model. This diversification does not reduce total risk. It simply spreads the exposure.

The network of connections has expanded significantly. Volatility links increased from nine to 35. Links involving extreme movements rose from 17 to 39. These are statistical predictive connections. They indicate deeper regional interdependence. Monitoring only the largest risk contributor is insufficient. Authorities must track disturbances moving through multiple currencies. The field of view must widen.

Yen influence doubles in recent years

The yen’s average contribution to risk nearly doubled. It rose from 7.52% to 14.74%. This covers the period from October 2018 to September 2025. Network analysis confirms the yen’s role. It is a dominant transmitter of spillovers. This holds true across both comparison periods. The currency’s weight has shifted. Surveillance agendas must reflect this change.

Policymakers face a difficult balancing act. They must assess domestic safeguards. They must also manage external connections. Stronger internal defenses are necessary. They are not sufficient alone. Shocks can enter resilient economies through these links. The form of vulnerability has changed. The magnitude of potential impact remains high. Precise monitoring is the only defense.
