Viewpoint: RBI intervention here to stay but INR FX may do better in Q1 2021


  • INR's underperformance in 2020 has been quite stark given the supportive balance of payments backdrop for the currency. The current account balance has shifted into surplus for the first time since 2004 and net FDI inflows have more than offset net portfolio outflows. INR FX is also cheap relative to our short term fair value model and has not caught up with the improved risk back drop reflected in higher equities.
  • This large divergence mainly reflects the RBI's continued aggressive FX intervention, which has seen FX reserves for the central bank rise sharply and offset the balance of payments surplus.
  • In this piece we outline the medium term drivers of RBI's FX intervention, which we feel are mainly geared around currency competitiveness. India inflation is generally higher than its trading partners, which means nominal FX appreciation needs to be contained to offset this trend, while India's share of global goods exports has stagnated in recent years. The country also has structural trade deficits with big manufacturing economy's like China.
  • We conclude that RBI FX intervention will remain a key feature of the INR FX landscape.
  • Still, there is a scope for the intervention pace to moderate from heady levels into 2021. Historically, stronger wholesale inflation pressures sees the pace of intervention slow as the authorities become more comfortable with some FX strength to offset imported inflation pressures. A continued recovery in global commodity prices suggests the risks for India's wholesale inflation outlook are skewed to the upside.
  • FX intervention also tends to come down when export and IP growth trends improve, which is also a risk as we move into early 2021. Coupled with the fact that Q1 tends to be the best quarter for INR FX from a seasonal stand point, suggests to us the market will use USD/INR spikes between now and year end as dollar selling opportunities. See the full note below for more details.


INR underperforms in 2020…

INR has been an underperformer within the EM Asia FX space during 2020, see the first chart below. The FX is down 3.5% against the USD year to date, with IDR the next worse at -2% YTD.

On the surface INR weakness is at odds with an improving external balance back drop for the currency. After all, the current account balance moved back into surplus in Q2 of this year for the first time since the end of 2004. The second chart below overlays the yearly change in the Indian current account balance (as a % of GDP) against the yearly change in INR versus the USD. So, the current account is nearly 2.5% higher relative to last year, yet INR is still comfortably weaker against the USD.

It's also difficult to make the case that capital outflow pressures have offset the improvement in the current account balance. To be sure, portfolio inflows have not been a source of support for INR for much of 2020. However, this has been more than offset by the continued upward trend in net FDI inflows, see the chart below. In this sense, it's difficult not to come away with the impression that India's overall balance of payments position has been very resilient through the course of 2020.

Our short-term fair value model for USD/INR also paints a supportive picture for the rupee. The chart below plots spot USD/INR against the fair value metric, which reflects relative equity market performance between India and major developed markets, the US 10yr yield and commodity prices (which serve as a proxy for global growth expectations). At the moment, the fair value suggests USD/INR spot should be in the low 71.00 region versus the current 73.90. This represents close to a 4% differential.

…as RBI intervention offsets improving balance of payments

The big discrepancy between India's balance of payments health and INR FX performance reflects RBI's strong intervention stance. The chart below plots RBI's net FX purchases, on a rolling 12-month sum basis, with the trend clearly surging higher over the past 12 months.

The RBI's strong intervention stance likely reflects a number of factors:

Firstly, Indian inflation generally runs ahead of the pace seen in the rest of the world. This is arguably not that surprising, as inflation in an emerging market economy will generally be running stronger than that in other major developed economies. However, as the chart below illustrates this divergence has widened substantially in the past 12 months. The flow on effect from this is that it makes your exchange rate more expensive, as the price of your goods is rising more quickly, on average, than the rest of the world's. This is seen when we look at India's real effective exchange rate, which adjusts for both relative exchange rate and inflation moves between India and its major trading partners, see chart 7 below. So even with INR's underperformance in the nominal space, as outlined in Chart 1, its stronger inflation rate compared to the rest of the world, has keep its REER very high.

An expensive exchange rate will dampen export competitiveness, all else equal. There is no doubt the Indian authorities are looking to boost export competitiveness and aid economic growth as a medium-term policy goal. This, in turn, would reduce India's trade deficit and shift away from persistent current account deficits. In the goods sector, India's share of global exports has stagnated in recent years, with a high exchange rate not helping this process.

One country with which India's trade balance has deteriorated noticeably over the past decade has been China. The chart below plots the 12-month rolling sum of the trade balance between the two economies. This is likely to have been another focus point for the authorities in looking to reduce the structural trade deficit. The last few years has seen some improvement, with the deficit moving to -$40bn from -$60bn, but no doubt the authorities would like to see further improvement in coming years. INR FX has underperformed CNH this year by a decent margin (see Chart 1 above), so in a nominal sense competitiveness has improved but India's inflation rate is still well above China's.

What could change RBI's strong intervention stance...

Our estimates suggest RBI intervention remained strong in October and through the first half of November
, as headline FX reserves rose $18.7bn and FX valuation affects didn't appear to be that large. In November to date FX reserves are up close to $13bn and while the USD has been weaker, thereby boosting headline FX reserves, it's unlikely this accounts for all of the rise in reserves.

The structural factors outlined above, particularly around export competitiveness and trying to boost exports as a share of Indian GDP, will continue to play out over the medium to longer term. This suggests RBI FX intervention will remain a key part of the INR FX landscape for the foreseeable future.

Of course, the pace of intervention may not remain as strong as what it has been, which could open a window for INR FX appreciation, against what is still expected to be a supported balance of payments backdrop into the early parts of 2021.

…concerns around domestic inflation and an economic rebound are the most likely catalysts

We noted above that structurally higher inflation in India compared to its major trading partners will drive intervention from a competitiveness standpoint. It's important to note though that to some extent this is a double edge sword. A weaker INR FX rate will also drive import costs higher, all else equal. This is something the authorities may be more mindful in the current context, as domestic inflation pressures are very elevated, as chart 6 above illustrated.

At the moment higher domestic inflation is mainly reflective of higher food costs. The Indian government expects food costs to come down as supply conditions improve and on the arrival of new crops (see this link for more details). Upstream or wholesale price pressures may trend higher, particularly if the global economy continues to improve in 2021. Chart 9 below overlays a commodity price index against the yoy change in Indian wholesale prices.

Arguably the INR exchange rate is going to have a greater influence on wholesale inflation, as this will be dominated by imported commodities, such as oil. Interestingly, if we overlay India wholesale inflation against RBI net purchases of USDs (or FX intervention) there is a reasonable inverse relationship, see chart 10 below. That is, periods of weaker wholesale inflation trends tend to be associated with higher levels of FX intervention and vice versa when wholesale inflation is rising. This makes sense, as weaker wholesale inflation trends should leave the central bank more comfortable to intervene and weaken the rupee, whilst stronger wholesale inflation should leave the RBI comfortable with a stronger exchange rate (and lower FX intervention) to dampen offshore inflation pressures, at least in an all else is equal sense.

Chart 10: RBI FX intervention and wholesale inflation trends

Not surprisingly, the correlation between wholesale inflation and RBI FX intervention is quite negative at -61%. This correlation is much stronger than the equivalent correlation with Indian CPI, see chart 11 below. FX intervention also has negative correlations with Indian export and IP growth. This is not surprising as well in the sense that weaker growth outcomes drive higher intervention efforts to maintain exchange rate competitiveness. The final two bars in the chart represent the correlation between FX intervention and net FDI and portfolio inflows. The positive results show that stronger capital inflow momentum sees FX intervention rise. This is a sensible approach from the RBI in that it's using these capital inflows to boost FX reserves, which can be used at later date if risk aversion and outflow pressures spike.

The modest pickup in wholesale inflation is already pointing to some easing in the pace of FX intervention. If the global inflation pulse recovers further into 2021, via higher commodity prices, this may prompt some moderation in FX intervention and acceptance of a stronger INR FX rate from the central bank. Likewise in terms of an improvement in export and Industrial production growth – to date Indian export growth has lagged the improvement seen elsewhere in the region Some catch up in 2021 could at least see the central bank temper its intervention pace and create a window for the FX to catch up with the firmer EM Asia trend.

Any softening in the domestic inflation trend is also likely to be seen as INR positive. It will improve the real yield backdrop, which is currently negative. Any shift back to positive real yields should encourage fresh inflows into local bonds from offshore investors. It will also allow greater scope for the RBI to ease policy further, which has typically been a positive for local equities. The RBI may also be less concerned about REER appreciation in an environment of lower headline inflation in the domestic economy.

The first few months of the year tend to be positive from a seasonal standpoint for INR FX, see the final chart below. This is likely to reflect that the current account deficit is typically lower during this period in the lead up to India's fiscal year end. Our bias would be to look for INR FX to play some catch up through Q1 of next year and spikes in USD/INR between now and the end of the year should be viewed as selling opportunities in our view.
