Reserve Bank of India Governor Sanjay Malhotra’s interview with moneycontrol.com has provided a useful explanation of the restrictions on foreign exchange hedging. He clarified that the reserve requirement on customer hedges concerns current-account exposures, not capital-account transactions, and ruled out capital controls.

Whether markets agree with the RBI's diagnosis is another matter. At least they now have a better understanding of what the central bank was seeking to achieve. 

The trouble is that an explanation delivered several days after a decision can begin to sound like a post-hoc justification, however compelling the original rationale may have been.

When the restrictions arrived around midnight on Friday, banks were like deer caught in the headlights. For the next two days, they struggled to understand what the measures meant, how to implement them and what to tell their customers. The RBI had imposed stringent new obligations without adequately explaining their rationale. A central bank should not leave the institutions it regulates guessing about its intentions.

A circular establishes an obligation. It need not carry the entire economic argument behind it, but that argument should be available separately when the obligation is imposed. Otherwise, the RBI leaves room for fears that it subsequently has to dispel, including whether restrictions on hedging are a prelude to restrictions on capital flows.

Ready Answers
A short Q&A from the RBI’s spokesperson could have explained what the Foreign Exchange Risk Reserve is, why it was introduced and which transactions it covers. More importantly, it could have set out what the RBI had observed that banks, importers and smaller businesses could not see.

The central bank need not disclose confidential supervisory information to explain the behaviour it wants to change and why the chosen instrument should change it. These are questions about policy reasoning, not merely the mechanics of compliance.

The People’s Bank of China offers a useful model. Its spokesperson’s Q&A on the reserve requirement for foreign exchange forward sales explains the rationale, how corporate hedging can generate spot-market pressure, and why it does not regard the instrument as a capital control.

That explanation was useful even for understanding the RBI’s intervention.

Indian banks and businesses should not have to turn to another central bank to understand the thinking behind their own regulator's actions.

An interview can add detail, invite challenge, and test the official explanation. It should supplement an account already available to everyone, rather than fill gaps left when the rules were issued. Nor should every clarification require the governor’s personal intervention when a written response from the institution would serve the purpose.

The October 7 policy exposed the other side of the problem. The rate increase and shift to calibrated tightening initially left the currency market steady. The press conference then emphasised the mildness and conditionality of that tightening, and the rupee resumed its decline towards 97 per dollar.

A central bank cannot control how markets interpret its words, but it must take responsibility for the signals it chooses to send.

There was no need to imply a predetermined sequence of rate increases. The RBI could have retained complete policy flexibility by emphasising that it would remain vigilant and respond to evolving conditions. Instead, the overqualifications risked drawing more attention to what the central bank might not do than to what it had just done.

Written Discipline
The lesson from both episodes is the value of carefully considered written communication. Monetary policy statements, regulatory announcements and accompanying explanations should receive the same attention as the decisions themselves. Officials should remain close to those formulations when answering questions at press conferences or speaking at public forums.

The written word has an advantage. It can be examined, debated and revisited without the ambiguity that sometimes accompanies an impromptu explanation. It becomes a common reference point for markets, businesses and policymakers. A press conference should illuminate the written statement, not leave the market wondering which version of policy to believe.

This does not mean the RBI should avoid questions or refrain from changing its position. Central banking requires flexibility, and fresh information can justify a change in course. But such changes are better communicated through considered statements, speeches or updated FAQs than through qualifications that create uncertainty about the original message.

The governor's interview has helped explain the RBI's recent actions. That is useful, but it also demonstrates how much could have been communicated when the measures were first announced. The test of central bank communication is not how convincingly it explains a decision after the event, but how little room it leaves for misunderstanding when the decision is made.
