Yesterday, RBI reported that India's FX (forex) reserves has made a new high - $612.73 bln for the week ending July 16, 2021.

This data is issued by RBI every Friday with one week lag. One can get to see the same on the link below:

India FX reserves has grown over the year and is now the world's 5th largest. Image
So, what is the significance of this number - FX Reserves?

FX reserves basically represent the total foreign currency holdings that RBI has. Higher the reserves, better it is for the stability of it's currency.
For any EM central bank, FX reserves works as the first line of defence against any sharp reversal in its currency, arising out of any global risk-off scenario (taper tantrum in 2013) or due to major capital outflows from India, as was seen in March 2020. Image
Local currency can also come under severe pressure (weakening), if trade deficit (imports > exports) continue to surge month after month and there is not enough capital flows through FPI or FDI channel to meet the shotfall.
In such cases, RBI intervenes by selling dollar from its reserves to avoid any sharp upside move in USDINR or weakening in rupee.
However, it does not mean that RBI will not allow the rupee to depreciate at all.

RBI objective is just to smoothen the volatility and not change the direction.
If global factors are not in favour and most of emerging market currencies are also weakening against dollar, RBI will also allow INR to depreciate but may be at an engineered pace.
In March 2020, when COVID led sell-off happened in all markets, INR also weakened from 72.50 to 76.90 levels, in line with other EM currencies, despite intervention (sell dollars) from RBI. Hope this clears that it is there to smoothen the volatility and not the direction.
Finally, it is also important to note that RBI can intervene from buy side as well, if it thinks INR is appreciating too fast at a time.
Just for info - in FY21, RBI maximum intervention was on buy side, as dollars inflows was just pouring in from both FPI and FDI channel. RBI bought dollar to the tune of $88 bln in FY21.
Hope this helps to understand why FX reserves are important, and central bank considers it as first line of defence.

In nutshell, RBI works as market stabilizer and this makes currency interesting. Isn't so?

Let's learn, adapt and grow.

I have been talking about USDINR for some time. But one cannot trade comfortably in the product unless understand how the underlying moves. And the best way to understand is historical volatility over different time frame.
Given that equity has India VIX as a reference point, currency does not have as of now. We are looking at how we can help the option traders with this data point. Will come back on this.
But let's today focus on historical volatility. Right now volatility in USDINR is sub 4% but it is not the lowest. It almost touched 3% in Feb'20. Image

Want to understand what makes #USDINR interesting from an individual #option trader perspective.

Let's try to understand this in this thread. USDINR has both weekly and monthly options contract which are fairly liquid. Today was weekly expiry.
Weekly options expire every Friday at 12:30 pm and monthly options at 2 days prior to last working day of the month. Margin applicable in USDINR is normally between 2.5% to 3% depending upon volatility.
Margin for one lot of USDINR #straddle (74.50 July 30 expiry - weekly contract) is roughly Rs. 2600/2700 and premium received is around 35p, which on one lot comes to Rs. 350 ($1000*0.35).

Sometimes, regulatory changes have asymmetric impact on different products within same eco-system. Peak margin seems to be one, having salutary effect on currency volume on Indian exchanges.
Currency volumes on Indian exchanges (NSE + BSE) seem to be gaining momentum this year, after an almost flat volume growth over the last 3 years. Until June end, ADV is up by almost 31%. Image
But what is interesting to note is increasing option share in total volume.

Since Dec'20, when peak margin got introduced, option share in total volume (futures+option) is slowly inching up, thanks to increasing interest in weekly options contract + possible peak margin effect. Image

USDINR futures closed at 74.71 for the day, almost 32p lower, despite dollar index holding up well. If private flow is the main reason for today's left side move in USDINR, overarching narrative for today can construed as capital flows.
Remember we talked about how it is important to identify narratives, and how it keep shifting from one factor to another.

Let's see if this narrative (flows) can play out on Thursday as well, in the background when dollar index is still holding up well around 93 levels and US 10Yr bond quoting below 1.20.

Capital flows is one of the major indicators to look at, for INR movement. Higher the inflows, better it is for INR and vice versa.

But along with inflows, it is also important to see the quality and stickiness of flows.
Since India is a net importer country, meaning imports more than export, (thanks to large share of oil in import basket), it needs to meet its shortfall through capital flows.
A country gets the flows mainly through 3 sources:

1) Equity
2) Debt and
3) FDI

Since currency is a pair trading - trading of currency of one country vs other (USD vs INR), there are two ways to look at a currency pair strength or weakness.
For example - in USDINR, when we say INR is strengthening, it can happen on account of two things - dollar weakness or INR own intrinsic strength.
When I say, INR intrinsic strength, it basically means strength on account of domestic factors, like economic (GDP) growth, positive real rates (inflation lower than policy rates) or improving trade balance (exports doing better import) etc.
