Preliminary Pricing Supplement Subject to Completion: Dated March 9, 2021 To the Product Prospectus Supplement FIN-1 Dated September 20, 2018, and the Prospectus and Prospectus Supplement, each dated September 7, 2018			$ __________ Redeemable Leveraged Steepener Notes, Due March 15, 2041 Royal Bank of Canada

Royal Bank of Canada is offering the Redeemable Leveraged Steepener Notes (the “Notes”) described below.

The CUSIP number for the Notes is 78014RDG2. The Notes will not be listed on any securities exchange.

The Notes will pay interest quarterly, on the 15^th day of March, June, September and December of each year, commencing on June 15, 2021. During the first year of their term, the interest rate on the Notes is fixed. After the first year of their term, the amount of interest payable on the Notes will depend on the Reference Rate. The Reference Rate (as defined in more detail below) will be equal to the difference between the 30 year CMS rate and the 5 year CMS rate. Interest will accrue at the following rates during the indicated years of the term of the Notes:

We may call the Notes in whole, but not in part, on March 15, 2022 and quarterly thereafter on each interest payment date, upon at least 10 New York or London business days’ prior written notice.

Investing in the Notes involves a number of risks. See “Risk Factors” on page P-8 of this pricing supplement, “Additional Risk Factors Specific to the Notes” beginning on page PS-5 of the product prospectus supplement FIN-1 dated September 20, 2018 and “Risk Factors” beginning on page S-1 of the prospectus supplement dated September 7, 2018.

The Notes will not constitute deposits insured by the Canada Deposit Insurance Corporation, the U.S. Federal Deposit Insurance Corporation or any other Canadian or U.S. government agency or instrumentality. The Notes are not subject to conversion into our common shares under subsection 39.2(2.3) of the Canada Deposit Insurance Corporation Act.

Neither the Securities and Exchange Commission (the “SEC”) nor any state securities commission has approved or disapproved of these securities or determined that this pricing supplement is truthful or complete. Any representation to the contrary is a criminal offense.

The initial estimated value of the Notes as of the date of this pricing supplement is $930 per $1,000 in principal amount, which is less than the price to public. The final pricing supplement relating to the Notes will set forth our estimate of the initial value of the Notes as of the Pricing Date, which will not be less than $880 per $1,000 in principal amount. The actual value of the Notes at any time will reflect many factors, cannot be predicted with accuracy, and may be less than this amount. We describe our determination of the initial estimated value in more detail below

RBC Capital Markets, LLC will offer the Notes at varying public offering prices related to prevailing market prices, and will purchase the Notes from us on the issue date at a purchase price that is expected to be between 97% and 100% of the principal amount. See “Supplemental Plan of Distribution (Conflicts of Interest)” below.

We will deliver the Notes in book-entry only form through the facilities of The Depository Trust Company on or about March 15, 2021, against payment in immediately available funds.

HISTORICAL INFORMATION

Historically, the High-Side Reference Rate and the Low-Side Reference Rate, and the difference between them, have experienced significant fluctuations. Any historical upward or downward trend in these rates during any period shown below is not an indication that the interest payable on the Notes is more or less likely to increase or decrease at any time during the term of the Notes. We cannot make any assurances that the future levels of the High-Side Reference Rate and the Low-Side Reference Rate will result in holders of the Notes receiving any interest payments after the first year of the term of the Notes.

The Reference Rate was 1.113% on March 8, 2021. The graph below sets forth the historical performance of the Reference Rate from March 8, 2001 through March 8, 2021.

The historical performance shown above is not indicative of future performance.

HYPOTHETICAL EXAMPLES

The table below presents examples of the hypothetical interest which will accrue on the Notes with a principal amount of $1,000 after the first year of the term of the Notes. The examples below are for purposes of illustration only. The actual interest payments will depend on the actual difference between the High-Side Reference Rate and the Low-Side Reference Rate on each Interest Determination Date. Whether or not you would receive interest at the hypothetical interest rates below would depend on, among other things, whether or not we exercise our option to redeem the Notes.

RISK FACTORS

The Notes involve risks not associated with an investment in ordinary floating rate notes.  An investment in Redeemable Leveraged Steepener Notes entails significant risks not associated with similar investments in a conventional debt security, including, but not limited to, fluctuations in the High-Side Reference Rate and the Low-Side Reference Rate and other events that are difficult to predict and beyond our control.  This section describes the most significant risks relating to the terms of the Notes.  For additional information as to the risks related to an investment in the Notes, please see the accompanying product prospectus supplement, prospectus supplement and prospectus.  You should carefully consider whether the Notes are suited to your particular circumstances before you decide to purchase them.  Accordingly, prospective investors should consult their financial and legal advisers as to the risks entailed by an investment in the Notes and the suitability of the Notes in light of their particular circumstances.

Risks Relating to the Terms and Structure of the Notes

After the First Year of the Notes, the Amount of Interest Payable Is Uncertain and Could Be 0.00%. After the first year of the term of the Notes, the amount of interest payable on the Notes in any interest period will depend on whether and the extent to which the High-Side Reference Rate is greater than the Low-Side Reference Rate on the related Interest Determination Date. If the High-Side Reference Rate does not exceed the Low-Side Reference Rate on any Interest Determination Date, the rate of interest payable for the related interest payment period will be 0%. The High-Side Reference Rate may only exceed the Low-Side Reference Rate by a small amount, such that the amount of interest that you receive any applicable Interest Payment Date may be minimal. As a result, the effective yield on the Notes may be less than what would be payable on our conventional notes of comparable maturity. The actual interest payments on the Notes may not compensate you for the effects of inflation and other factors relating to the value of money over time.

The Amount of Interest Payable on the Notes in Any Interest Period Is Capped. The interest rate on the Notes for each interest period during the variable interest rate period is capped for that period at the maximum interest rate of 8.00%. You will not receive interest at a rate of more than 8.00% per annum for any quarterly interest period, even if the difference between the High-Side Reference Rate and the Low-Side Reference Rate increases substantially. Accordingly, you will not receive the full benefit of the High-Side Reference Rate exceeding the Low-Side Reference Rate due to this maximum interest rate.

We May Call the Notes Prior to Maturity. We have the option to redeem the Notes on the dates set forth above. It is more likely that we will redeem the Notes prior to their stated maturity date to the extent that the interest payable on the Notes is greater than the interest that would be payable on our other instruments of a comparable maturity trading in the market. If the Notes are redeemed prior to their stated maturity date, you may have to re-invest the proceeds in a lower rate environment, and you will not receive any further payments on the Notes.

Investors Are Subject to Our Credit Risk, and Our Credit Ratings and Credit Spreads May Adversely Affect the Market Value of the Notes. Investors are dependent on our ability to pay all amounts due on the Notes on Interest Payment Dates and at maturity, and, therefore, investors are subject to our credit risk and to changes in the market’s view of our creditworthiness. Any decrease in our credit ratings or increase in the credit spreads charged by the market for taking our credit risk is likely to adversely affect the market value of the Notes.

Risks Relating to the Initial Estimated Value of the Notes

The Initial Estimated Value of the Notes Will Be Less than the Price to the Public.  The initial estimated value that will be set forth in the final pricing supplement for the Notes does not represent a minimum price at which we, RBCCM or any of our affiliates would be willing to purchase the Notes in any secondary market (if any exists) at any time.  If you attempt to sell the Notes prior to maturity, their market value may be lower than the price you paid for them and the initial estimated value.  This is due to, among other things, changes in the level of the Reference Rate, the borrowing rate we pay to issue securities of this kind, and the inclusion in the price to the public of the underwriting discount and the estimated costs relating to our hedging of the Notes.  These factors, together with various credit, market and economic factors over the term of the Notes, are expected to reduce the price at which you may be able to sell the Notes in any secondary market and will affect the value of the Notes in complex and unpredictable ways.  Assuming no change in market conditions or any other relevant factors, the price, if any, at which you may be able to sell your Notes prior to maturity may be less than your original purchase price, as any such sale price would not be expected to include the underwriting discount and the hedging costs relating to the Notes. In addition to bid-ask spreads, the value of the Notes determined for any secondary market price is expected to be based on the secondary rate rather than the internal funding rate used to price the Notes and determine the initial estimated value.  As a result, the secondary price will be less than if the internal funding rate was used.  The Notes are not designed to be short-term trading instruments.  Accordingly, you should be able and willing to hold your Notes to maturity.

The Initial Estimated Value of the Notes on the Cover Page and that We Will Provide in the Final Pricing Supplement Is an Estimate Only, Calculated as of the Time the Terms of the Notes Are Set. The initial estimated value of the Notes will be based on the value of our obligation to make the payments on the Notes, together with the mid-market value of the derivative embedded in the terms of the Notes.  See “Structuring the Notes” below.  Our estimate will be based on a variety of assumptions, including our credit spreads, expectations as to interest rates and volatility, and the expected term of the Notes.  These assumptions are based on certain forecasts about future events, which may prove to be incorrect.  Other entities may value the Notes or similar securities at a price that is significantly different than we do.

The value of the Notes at any time after the pricing date will vary based on many factors, including changes in market conditions, and cannot be predicted with accuracy.  As a result, the actual value you would receive if you sold the Notes in any secondary market, if any, should be expected to differ materially from the initial estimated value of your Notes.

Risks Relating to the Reference Rate

Recent Regulatory Investigations Regarding Potential Manipulation of the High Side Reference Rate and the Low Side Reference Rate May Adversely Affect Your Notes. It has been reported that certain U.S. and non-U.S. regulators are investigating potential manipulation of these rates and other swap rates. If such manipulation occurred, it may have resulted in these rates being artificially lower (or higher) than it or they would otherwise have been. Any changes or reforms affecting the determination or supervision of these rates in light of these investigations may result in a sudden or prolonged increase or decrease in these reported rates, which may have an adverse impact on the trading market for CMS-benchmarked securities, such as the Notes, the market value of your notes and the payments on your Notes after the first year of their term.

SUPPLEMENTAL PLAN OF DISTRIBUTION (CONFLICTS OF INTEREST)

We expect that delivery of the Notes will be made against payment for the Notes on or about March 15, 2021, which is the second (2nd) business day following the Pricing Date (this settlement cycle being referred to as “T+2”). See “Plan of Distribution” in the prospectus supplement dated September 7, 2018. For additional information as to the relationship between us and RBC Capital Markets, LLC, please see the section “Plan of Distribution—Conflicts of Interest” in the prospectus dated September 7, 2018.

After the initial offering of the Notes, the price to the public may change.

The value of the Notes shown on your account statement may be based on RBCCM’s estimate of the value of the Notes if RBCCM or another of our affiliates were to make a market in the Notes (which it is not obligated to do).  That estimate will be based upon the price that RBCCM may pay for the Notes in light of then prevailing market conditions, our creditworthiness and transaction costs.  For a period of up to approximately six months after the issue date of the Notes, the value of the Notes that may be shown on your account statement is expected to be higher than RBCCM’s estimated value of the Notes at that time.  This is because the estimated value of the Notes will not include the underwriting discount and our hedging costs and profits; however, the value of the Notes shown on your account statement during that period may initially be a higher amount, reflecting the addition of RBCCM’s underwriting discount and our estimated costs and profits from hedging the Notes.  This excess is expected to decrease over time until the end of this period.  After this period, if RBCCM repurchases your Notes, it expects to do so at prices that reflect their estimated value.

We may use this pricing supplement in the initial sale of the Notes.  In addition, RBC Capital Markets, LLC or another of our affiliates may use this pricing supplement in a market-making transaction in the Notes after their initial sale.  Unless we or our agent informs the purchaser otherwise in the confirmation of sale, this pricing supplement is being used in a market-making transaction.

Each of RBCCM and any other broker-dealer offering the Notes have not offered, sold or otherwise made available and will not offer, sell or otherwise make available any of the Notes to, any retail investor in the European Economic Area (“EEA”) or in the United Kingdom. For these purposes, the expression “offer” includes the communication in any form and by any means of sufficient information on the terms of the offer and the Notes to be offered so as to enable an investor to decide to purchase or subscribe the Notes, and a “retail investor” means a person who is one (or more) of: (a) a retail client, as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); or (b) a customer, within the meaning of Directive (EU) 2016/97, as amended, where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (c) not a qualified investor as defined in Regulation (EU) 2017/1129 (the “Prospectus Regulation”). Consequently, no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the Notes or otherwise making them available to retail investors in the EEA or in the United Kingdom has been prepared, and therefore, offering or selling the Notes or otherwise making them available to any retail investor in the EEA or in the United Kingdom may be unlawful under the PRIIPs Regulation.

STRUCTURING THE NOTES

The Notes are our debt securities, the return on which is linked to the Reference Rate.  As is the case for all of our debt securities, including our structured notes, the economic terms of the Notes reflect our actual or perceived creditworthiness at the time of pricing.  In addition, because structured notes result in increased operational, funding and liability management costs to us, we typically borrow the funds under these Notes at a rate that is more favorable to us than the rate that we might pay for a conventional fixed or floating rate debt security of comparable maturity.  Using this relatively lower implied borrowing rate rather than the secondary market rate, is a factor that is likely to reduce the initial estimated value of the Notes at the time their terms are set. Unlike the estimated value included in the final pricing supplement, any value of the Notes determined for purposes of a secondary market transaction may be based on a different funding rate, which may result in a lower value for the Notes than if our initial internal funding rate were used.

In order to satisfy our payment obligations under the Notes, we may choose to enter into certain hedging arrangements (which may include call options, put options or other derivatives) on the issue date with RBCCM or one of our other subsidiaries.  The terms of these hedging arrangements take into account a number of factors, including our creditworthiness, interest rate movements, the volatility of the Reference Rate, and the tenor of the Notes.  The economic terms of the Notes and their initial estimated value depend in part on the terms of these hedging arrangements.

The lower implied borrowing rate is a factor that reduces the economic terms of the Notes to you.  The initial offering price of the Notes also reflects the underwriting commission and our estimated hedging costs.  These factors result in the initial estimated value for the Notes on the pricing date being less than their public offering price.  See “Risk Factors—The Initial Estimated Value of the Notes Will Be Less than the Price to the Public” above.
