Both the severity of the financial crisis and its massive collateral damage to the real economy have confounded the optimists over the past year. Quite often, experts claimed that "the worst of the financial crisis is behind us", only to be bush-whacked by the next big bail-out or credit seizure.

Equally remarkable, and much worse in impact, has been the speed at which the cumulating financial crisis has throttled real economic activity since summer 2008. The rapid onset of recession in industrial (advanced) countries has clearly overwhelmed the forecasting abilities of many institutions, including the IMF.

As recently as July this year, the IMF foresaw the world economy growing at 3.9 percent in 2009, advanced economies at 1.4 percent and developing countries at 6.7 percent. By early November (just four months later) these forecasts had been slashed down to 2.2 percent, minus 0.3 percent and 5.1 percent, respectively.

Nor does the recent "advance release" of the global outlook for 2009 by UNCTAD provide any succour. Like the IMF, the UNCTAD foresees global growth at just over 2 percent in 2009 at PPP weights and at only 1 percent at market exchange rates. The latter number means that global growth in 2009 is expected to be at only about a quarter of the pace enjoyed in 2006 and 2007.

Both institutions forecast severe damage to world trade, which is expected to expand at only 2 percent in 2009 as compared to over 9 percent in 2006 and 7 percent in 2007. For the Asian giant, China, both the IMF and UNCTAD expect growth to slow to about 8.5 percent in 2009 from the scorching 12 percent pace of 2007. Interestingly, several China-based analysts foresee much sharper deceleration.

What about India? How bad will it get for us? The official estimates of GDP growth for the first two quarters of 2008/9 stayed above 7.5 percent. However, industry-wide indications after September are uniformly gloomy.

There are reports of significant declines in output of automobiles, commercial vehicles, steel, textiles, petrochemicals, construction, real estate, finance, retail activity and many other sectors. Exports fell by 12 percent in dollar terms in October and advance information points to a similar decline in November. After September, the economy seems almost to have gone over a cliff.

When available, the official data are likely to record a sharp slowdown in the second half of the year, possibly steep enough to drag full year growth in 2008/9 to below 7 percent. What's more, given the strongly recessionary conditions expected to prevail in the world economy in 2009, there is no prospect of a quick turnaround in India. Indeed, on a tentative basis, I would suggest that we might be lucky to achieve GDP growth of even 6 percent in 2009/10.

What about economic policy? Can we not deploy monetary, fiscal and exchange rate policies to insulate our growth momentum from adverse external conditions? The short answer is: only to a limited degree. I outlined the main arguments last fortnight (BS, November 27).

Monetary policy had already been aggressively loosened by early November and the RBI provided a further, well-balanced package last Saturday, notably including a 1 percent cut in the repo and reverse repo rates.

Given the continued high rate of CPI inflation through October (latest data) and, perhaps more significantly, recent pressures on the exchange rate, the present scope for further policy rate reductions appears limited. That situation might change if external imbalances improve if a falling oil import bill and slowing non-oil imports outweigh the drop in export earnings and if capital flows stabilize.

On the fiscal front, the government had pretty much exhausted the available fiscal space through its record Rs 237,000 crore (4.5 percent of GDP) supplementary demand in October. Though undertaken for quite different reasons, its timing may turn out to be quite fortunate.

Against this background the government was wise to limit last Sunday's "fiscal stimulus" to a modest affair, totaling only about Rs 30,000 crore (Rs 300 billion), out of which two-thirds was for "additional plan expenditure", which may not be fully spent this fiscal year.

It may be far more important to actually spend the already budgeted plan expenditure effectively. If international oil and fertilizer prices stay at present levels, implying low or negligible subsidy rates (looking ahead) on price-controlled domestic sales, then there may be a case for a larger stimulus next year. Much will depend on the trajectory of revenues and other expenditures in a slowing economy.

While such unprecedented monetary loosening and massive supplementary expenditures will definitely help, they will not fully neutralize the negative impact of the severe global financial and economic crisis on India's exports, investment and consumption.

With over 60 percent of global GDP having toppled into recession, a significant deceleration of India's economic growth is simply unavoidable. After all, we share the same planet as America, Europe and Japan (and a rapidly slowing China). In this context a 6 percent economic growth in 2009/10 will be pretty good...if we achieve it.
