When Credit Suisse mapped global wealth last year, most of Asia was mustard green. The biggest difference in the way the map looks this year is that India is now blue.

That's not good news.

It indicates that the average wealth in the country has dropped to below $5,000 per person, above that being mustard green, below that blue.

Besides India, only a handful of other Asian countries fall under the blue category - the lowest of four - together with most of Africa.

Specifically, individual wealth in India dropped to $4,250 in the year that ended in June from $5,300 a year earlier, according to a study the bank released this week.

That's nearly a 20% decrease and much worse than the world-wide average, which saw individual wealth decline 5.2% to $49,000 per person, the report found.

In India, wealth per adult measured in terms of financial and non-financial assets like real estate - averaged much lower than in other major emerging markets. An average adult in China has assets worth $20,452; in Brazil this figure is $24,600 and in Russia $12,161, according to Credit Suisse.

Despite the growth of its economy, India was worse hit in percentage terms than debt-strapped Europe, which saw a 13.6% decline in wealth per adult.

But data for India is less bad than it may appear at first. Declining wealth levels are measured in dollars, not in rupees. The main reason India fared badly in global wealth comparisons is that, over the past year, the Indian currency lost around 20% of its value against the U.S. dollar. (See more on the rupee
