“Don’t dismiss Modern Monetary Theory (MMT) as unlikely to influence policy. This heterodox economic doctrine advocates sharply increased fiscal expenditures backed by money creation. An alluring promise of MMT is that it directly confronts a perceived flaw in today’s conduct of monetary policy: pumping liquidity into financial markets as the standard response to stock market and economic turbulence inflates asset price bubbles and thereby exacerbates income inequality …
Real assets provide a measure of inflation protection. TIPS, commodities, and REITs may appreciate as and when investors attempt to reposition for an inflationary regime.

Repositioning portfolios to hold capital assets domiciled in countries with more conservative policies provides an alternative approach to protecting portfolios from inflation.
