Managing Interest rate risk via Hedging 

What is Hedging ?
• Hedging is designed to provide certainty
• It’s a risk mitigation strategy against fluctuating interest rates, 
commodities, or foreign exchange movements
• Our discussion will focus on interest rate hedging
• What is the risk we are trying to avoid?
• There is a cost to have certainty via hedging, but there could be a 
even bigger one with taking a risk – i.e. uncertainty
• Finance Strategy – LTP – Financial Prudence (not taking undue risks)


Fixed or Floating rate interest cost ?
• There are two types of interest bearing debt
• Fixed rate - the interest rate remains constant over life of the debt
• Floating rate - the interest rate on the debt is re-priced generally every 90 
days
• Floating rate is generally cheaper 
than Fixed rate
Fixed Rates
• but interest rates change over 
time
Floating Rate
3 months 
• 90 days is 0.25%, 10 years is 3.5% 


How Council manages its Debt
• All Council debt is borrowed at a floating interest rate i.e. re-priced every 90 
days
• Funds are borrowed for various terms, overnight, 90 days to up to 17 years
• Interest rates risk on Councils debt is managed separately 
Note
LGFA
• Our cost to borrow to April 2025 is the 
90 day rate plus a fixed margin of 0.48%
• 90 day rate is 0.28% now
• i.e 0.76% for the next 90 days



Graph of 90 day Floating rate over time    Current Fixed rate SWAPS 16 Nov
Cost to fix via swap for 5 years to 
2025 is 0.37%

How is the councils interest rate risk managed ?
• The floating interest rate can be switched into fixed rate with an interest rate swap
• An interest rate swap can be for a short time i.e. 6 months or a long time i.e. 17 years +
• We have a portfolio of floating rate interest cost - some overlaid with fixed rate swaps
• Interest rate swaps are flexible they can be cancelled, they can be extended or shortened 
.. Banks are happy to do this ….  More on this later 
• Operation of Swaps governed by our Treasury Risk Management Policy

Example of a how a SWAP works
• WRC borrow funds at a floating interest rate (each 90 days the rate is re-
priced) and rates determined by the market were:
 4.25%, 3.75%, 3.50%, 3.00% on Drawdown,  March,  June,  September, 

Borrowed $10 million from LGFA on floating rate note for 1 year
• WRC enters into a swap to ensure a fixed interest rate for 1 year at 3.50%

Treasury Risk Management Policy 
• Policy sets out the parameters under which we manage our interest rate 
risk
• Reviewed every 3 years, any changes are advocated/supported by our 
Treasury Advisors –PwC and approved by ELT, FRAC, Council
• Policy provides latitude to take some view on interest rates - reviewed 
at least quarterly by PwC


Interest rate Hedging Policy parameters – Fixed rate 


Hedging/Fixed interest rate graphically  

SWAP valuations
• Swaps valued regularly, reported quarterly via our management reporting to Council
• Is an Accounting requirement, impact are: 
• Balance sheet valuation reflect the current position if swaps cancelled today
• Profit and Loss account amounts represent the changes between years
• Valuations vary as interest rate move up and down and as the swaps are used-
up/extinguished

Interest rate SWAPS are flexible
• Currently we have pressure with our LTP .. Can we use swaps to help us out ?
• Yes, anything is possible
• Its like your home mortgage you can easily change the rate … but there is often a cost
• An opportunity cost and a costs of the bank to pay  
• We can reduce interest costs in the next few years by extending out our swaps 
• Simplistically we pay fixed rate 5% for 2 years we can extend and pay 2.5% for 4 years  
• But after 2 years if we paid 5% we could pay 0.25% for the next two years instead  


Interest rate swaps – Swap extensions – Simple scenario 
• $100m of Debt and a swap on this to pay 5% for 2 years and want to extend 2 years
• Current 90 day floating rate is 0.25% and same for the next 4 years



What an extension looks like
Proposed extension
Completed extension


Extension scenario 1 – Target $2m per year over next 3 years
• Asked PwC to provide scenario of 
targeting saving of $2m over first 3 
years of LTP.
• Includes bank charges amounting to 
$2,200,000 
• Amends $160 million of swaps
• Average extension 9 years
• Terminal interest rates 2.6%  


Extension scenario 2 – Optimise Blend & Extend – rate reduction
• Asked PwC to provide scenario to 
optimise best value saving on 
extending high interest rate 
swaps
• Includes bank charges of 
$650,000
• Amends $60 million of swaps
• Average extension 7 years
• Terminal interest rates 2.5% 

Advantages of blend and extending swaps
• Can provide immediate interest cost savings
• Lowers average interest rate in early years
• Regret factor on execution is presently low, rates can go lower but limited  

Disadvantages of blend and extending swaps
• While initial saving, costs are increased in later years
• There is a cost to complete transaction – can be expensive
• There is no competitive pricing, have to take banks charges, or abandon
• Changes can range from 0.05% per annum to 0.20% depends on bank and 
market conditions
• Can create problems in latter years as cost reverse 

Recommendation
• There is no right or wrong answer
• Economically it does not stack up because of the bank costs, these are spread.. nevertheless 
are to be paid
• Would not do this in the ordinary course of business unless there is an imperative 
• What are our advisers recommending .. As above.
