6The carry trade and intervention risk
September 6, 2007 | Leave a Comment
While the baseline scenario for strategists at Merrill Lynch is one of no central bank intervention (60%), they see significant risk of intervention if extreme moves are seen in the carry trade in either direction - assigning a 30% probability to central bank action on a rapid unwind of the carry trade, and a 10% chance to intervention following a recovery of the carry trade to previous highs:
Our forecasts assume a gradual unwind of carry trades and protracted, but modest, JPY strength. This is unlikely to be environment where authorities deem intervention to be appropriate. However, there are two situations that could worry policymakers and justify a response.
Carry resumes
If carry trades recovery to their previous highs, intervention could take a number of forms. Authorities in Japan, Australia, New Zealand, Europe and Switzerland could attempt unilateral (either verbal or direct) intervention, with success dependent on whether monetary policy is aligned with FX policy. The ultimate end game for carry trades would be brought about by coordinated action.
Carry unwinds aggressively
In the event of a rapid carry trade unwind, Japan, Australia and New Zealand could attempt smoothing operations to slow the move, though probably not designed to generate a reversal. Coordinated action between these policymakers and possibly the US and Euro area are less likely, but possible, if carry unwind is viewed as being destabilizing to other asset markets.
Any move below USD-JPY 110 is likely to elicit a response from the Japanese, regardless if it is a quick move that occurs over a few weeks or a slow grind that occurs before November. Although previously content with some JPY strength, volatile moves or significant strength beyond exporters budget rate would be viewed as harmful to the economic recovery. Below 110 could generate the initial response with intervention operations becoming increasingly aggressive toward 106. These would be smoothing operations designed to alleviate downward pressure on USD-JPY, not to generate an outright reversal.
