Economic Framework

“China’s current-account surplus has swung considerably over the past two decades. But that volatility reflects where the excess savings went, not whether the underlying imbalance was fixed.” — Anantha Nageswaran & P.S. Srinivas, The Economist

Key Takeaway

Despite fluctuations in the headline Current Account surplus, China’s underlying structural imbalance—high national savings paired with repressed domestic household consumption—remains intact.

Flow Channels Explained

US Sovereign Debt: Depresses Western risk-free rates, driving global asset search.
Belt & Road (BRI): Channels capital goods surplus to developing economies via bilateral loans.
Industrial Capacity: Directs savings into high-tech EV/PV/Battery manufacturing, causing trade frictions.
