Why International Diversification Matters
Indian equity exposure has compounded at remarkable rates over the past two decades — Nifty 50 has delivered roughly 12-13% nominal CAGR, comfortably beating most developed-market indices in INR terms. That track record makes Indian-only portfolios look like a winning strategy. The reason most institutional UHNI portfolios still allocate 15-30% internationally has nothing to do with chasing higher returns elsewhere — it's about risk diversification under a few specific scenarios.
Three risks that international exposure mitigates:
-
Country-level event risk. A 1991 BoP crisis, a 1998 Asian Financial Crisis spillover, a 2013 taper tantrum — each saw the rupee fall 15-30% against the dollar in months, with simultaneous Indian equity drawdowns. A pure-INR portfolio compounds the loss; an international allocation provides a partial hedge because the foreign assets, valued in INR, appreciate during a rupee-weakness episode.
-
Sectoral concentration. The Indian listed equity universe is concentrated in financials, IT services, FMCG, and energy. Major secular trends — semiconductor design, biotech, cloud infrastructure, advanced materials — are largely absent from the Indian listed universe. International equity (especially US) provides exposure to these sectors that domestic markets cannot.
-
Currency depreciation as a structural feature. The INR has depreciated roughly 3-4% per year against the USD over the past 20 years (PPP-driven, anchored in the inflation differential). For an investor whose future expenses might include foreign assets — children's foreign education, international travel, medical care, real estate — holding foreign-currency-denominated assets is itself a hedge against this future-liability currency exposure.
The fourth, less obvious benefit: uncorrelated factor exposures. The US equity market loads heavily on the technology / innovation factor; the Chinese market on consumption-growth and policy-cycle factors; European markets on industrial-earnings and ECB-policy factors. Diversifying across these provides factor diversification beyond what any single domestic market can offer — relevant especially for the Andrew Ang macro-factor framework discussed in Module 9.
