Use case · Refinancing & swap restructuring
We're refinancing — what's the breakage on the existing swap?
The refi economics hinge on a number nobody on your side can produce: the mark-to-market the bank will charge — or pay — to break the swap. And it won't sit still. One debt advisory team watched a client's position go from £2m in the money to £6m against them inside a fortnight; for many advisors the breakage check is now "a weekly analysis we have to do", re-presented to the client every week. Meanwhile the only quote you have comes from the bank you're trying to leave.

A swap's breakage cost is its mark-to-market, and you can calculate it independently. Load the swap into BlueGamma to get the live MtM, BPV and a breakage-over-time forecast, then model the restructure yourself. BlueGamma is an interest rate data and pricing platform used by 80+ financial institutions for swap rates, forward curves and cap pricing across 30+ currencies.
Today, the standard workflow is this: you ask the bank that's on the other side of the trade what it costs to leave them. The counterparty with the opposite economic interest sets the exit price, and you have no independent number to hold against it.
How teams describe this moment
Verbatim from recorded calls with finance teams and advisors weighing an early refinancing, a restructure, or a termination. Attributed by role and firm type.
"Right now we have this requirement of putting this couple of [swaps off] over the next 3–4 months' time. So we need to know where [we] stand in terms of the [swap] if I have to terminate today or [in] three months' time."
Treasury team, Saudi energy & industrial conglomerate — USD swaps, termination timing over a 3–4 month window
"I think when [a colleague] ran it two weeks ago, it was at 2 million in the money. And then yesterday it was like −6, and the day before that it was like −2. So it has been moving a bit."
Debt advisory analyst, global debt advisory firm — SONIA swap, breakage re-presented to the client weekly
"I'm setting up my own sheet 'cause there's so many different swaps flying around everywhere… I'll pull the MTM and the PV01 and then put it in my sheet and it'll kind of self-calculate into the new swap… the timing point means that the number that I pull is never exactly right."
VP, infrastructure capital markets, global asset manager — ~60 portfolio companies, swaps embedded and novated at every refi
"Like when we refinance, you have that tail of the swap and you embed it into a new swap, or you want to, like, cash settle it, or novate it fully."
VP, infrastructure capital markets, global asset manager — the three exits every legacy swap faces at refinancing
"The bank has the option to cancel in the future… If the swap's in the money they probably will cancel, which is fine because at that point in time the lease has some increases in rental rates. So it's the perfect time to go out to market for refi… the hard part is I can't figure out how they're calculating the cost of that option."
Capital markets team, US real-estate developer — cancellable swap, embedded option priced only by the bank that holds it
"Sometimes it's to understand… what's the hedge breakage cost. We do generally have a look at this as well."
Project finance team, Middle East utility & IPP — breakage checked alongside every refinancing appraisal
How you're probably getting the number now
Three versions of the same problem: every route to the breakage figure runs through someone else's model, someone else's timing, or someone else's interest.
Ask the counterparty bank
The bank's breakage quote is mid MtM plus whatever unwind charge it chooses — and you can't see where one ends and the other begins. Asking a friendly second bank for a "quote" doesn't work either: as one debt advisor put it, "we may not necessarily want to reach out to our relationship contact[s] knowing full well they're not gonna get any business from us on a certain transaction."
Try to price it on a legacy market-data vendor / a terminal
For a plain vanilla swap, maybe. For the restructure you actually need to price — an off-market fixed leg, a mark spread over remaining years — one advisor who tried both was blunt: "Again, [the legacy vendor]… it wasn't even close… So it didn't work."
Build it in Excel and hope
A homemade MtM sheet needs a live SONIA/SOFR/EURIBOR curve to discount off — which usually means going back to the banks for the curve, or validating your tool against… the bank's own statement. And even with data, the number goes stale in transit. An infrastructure VP at a global asset manager described the workflow: "you kind of have to copy and paste it into the Excel and then the market's already moved" — "the timing point means that the number that I pull is never exactly right."
Give up on the structures you can't see into
Cancellable swaps, deal-contingent hedges, pre-hedges struck before the facility signs — the embedded optionality is priced only by the bank that holds it. A US real-estate capital markets team put it plainly: "the hard part is I can't figure out how they're calculating the cost of that option." One advisor reconciling a pre-hedge found the provider's number ~110 against their own — traced to a four-year vs five-year tenor assumption and mismatched interest dates. Without your own calc, you can't even find the mismatch.
Load the swap, see the breakage, model the exit
Everything below happens in the web app off live broker-sourced curves (30-second refresh) — no terminal, no calls to the desk.
Load the existing swap
Set up the trade once in the swap mark-to-market tool: start date, payment dates, day count, fixed rate — and the real notional profile. Amortising and custom profiles are supported; paste the outstanding-balance schedule straight from your loan model.
Read the live MtM — that's the mid breakage
The mark-to-market recalculates live and should sit within about a basis point of the bank's own mid, since BlueGamma consumes the same broker and exchange data the banks do. The gap between this number and the bank's breakage quote is the bank's unwind charge — now visible, now negotiable.
You can also value the swap as of a past date — as one Canadian real-estate financing advisor put it, "I can check a price that was given to me a few days ago and then see how… it was priced at that time." Useful when the bank's quote arrived on Tuesday and the conversation happens on Friday.
Forecast the breakage over time
The forecast MtM view holds the curve steady and rolls the swap forward, so you can watch the breakage amortise towards zero as each remaining interest payment drops away. Pair it with the forward-starting swaps view to see where replacement rates are expected to sit — and decide whether to refinance now or time it a few payment dates out.
This is exactly the question treasuries ask: a Saudi conglomerate's treasury needed to know "where we stand… if I have to terminate today or in three months' time", and a Middle East utility's project finance team, shown the forecast graph, said "this will help us time our refinancing decision as well."
Model the restructure yourself
Terminate vs roll: compare the NPV of breaking today and re-hedging at market against keeping the legacy rate. One debt advisory team runs this weekly for an infrastructure client — an £8.9m out-of-the-money SONIA position, PV01 around £800k, roughly 10bp embedded in the mark — and was surprised by the answer: "I didn't expect terminating existing swaps would be actually OK."
Blend / top-up: "If I were to keep my existing swap and then basically do a top up… how do I figure out the blended rate?" Weight the legs by PV01 — an existing swap at 4.19% plus a top-up at 4.81% blends to roughly 4.36%.
Blend-and-extend / off-market: set the restructure up as its component swaps — one holding the off-market fixed leg (which creates a new mark), one spreading that mark over the remaining years — and price each off the same curve.
Buy-down: use the swap's BPV (PV01) and replacement rate to convert an upfront payment into basis points off the fixed rate: cash injected ÷ BPV ≈ rate reduction.
Novation: when the existing hedge banks aren't part of the new financing, the swap either terminates or novates across — with execution and credit charges (advisors commonly pencil ~1bp execution and several bp of credit) layered on the mid. Knowing the mid first is what makes those charges visible line items rather than one opaque number.
Negotiate the exit — or track it daily
Walk into the breakage conversation with your own mid, your own forecast, and your own restructure pricing. If the swap survives the refi, keep it loaded: the daily MtM doubles as your collateral and margining check, with no download limits.
Your options when the breakage question lands
| Ask the counterparty bank | Legacy vendor / terminal | Homemade Excel MtM | BlueGamma | |
|---|---|---|---|---|
| Independent of the bank you're leaving | No — the counterparty sets the price | Yes | Partly — usually still needs the bank's curve | Yes — broker-sourced curves |
| Live mid MtM on your exact profile | On request, on their timing | Assemble it yourself | Only as good as your curve | Yes — amortising/custom profiles, 30-sec refresh |
| Breakage forecast over time | No | Not out of the box | Build it yourself | Yes — MtM rolled to zero over remaining payments |
| Prices off-market / two-phase restructures | Yes — at their spread | Failed in practice — "wasn't even close" | Days of work, hard to audit | Yes — set up each phase as a swap, priced to match bank results |
| BPV / replacement rate for buy-downs | On request | Assemble it yourself | Manual | Yes — shown live on every loaded swap |
| Re-run weekly while the deal is live | No — you can't call the desk every week | Yes, if you own a seat — often one shared terminal for the whole firm | Copy-paste, and "the market's already moved" | Yes — reload the saved swap, numbers refresh live |
| Cost | Hidden in the unwind spread | ~£20k+/seat/year, rising — one advisory firm "cancelled… it was just costing a fortune and they just kept on putting their prices up" — plus extract caps | Your analysts' time, every time | Flat monthly per-seat subscription — monthly flexibility, not a multi-year contract |
Teams already doing this
All quotes verbatim from recorded customer and trial calls, 2025–2026. Attributed by role and firm type — lenders, advisors, treasuries and funds from the UK, Nordics, Gulf, North America and Australia.
A partner at a Nordic debt advisory firm restructured a client's swap where the client insisted on keeping their existing off-market fixed rate — "they had like an, you know 3.65%… they said… we want that same rate… whatever the mark is, I don't care." That creates a new mark, which had to be spread over the remaining years. His words on how he priced it:
"We did a swap… in two phases, so the first phase was this off market 3.65 fixed leg that was creating a… new mark that we then spread out over… the last three years… All I did was, in your trial version, I just set up… two swaps. One was a mark to market and one was looking at the new, and then it was very easy to price it on that basis… We got very similar results [to the bank], so it worked. Again, [the legacy vendor]… it wasn't even close… So it didn't work."
A VP in infrastructure capital markets at a global asset manager described running a full hedge restructure around a signed deal: "We had put in these kind of deal contingent hedges and then the deal had signed… We wanted to restructure the hedge and then there was like embedding bits into this facility or that facility, and then afterwards novating it away to a bigger hedging bank group. So… me having been able to run a lot of those moving parts independently until the very end, which was the execution call…"
The stakes at that scale: "Monitoring the MTM is only worth it if you know you're really in the money for, like, a huge financing, and then you can, you know, extract like a couple 100 million out of the MTM to recap." As he framed the job itself: "the true value of the investment is a race to the bottom in terms of cost of capital — things like interest rate swaps and that kind of risk, you got to manage it properly."
"They've got an existing hedge in place and they're just asking: if we were to terminate the swaps today and enter into new swaps, what would that look like in terms of NPV versus rolling it over?… our recommendation would be to roll over the existing swaps… because they locked it in at a great rate back in [2021]… It's like a weekly analysis we have to do because you really don't know where rates are moving — but I didn't expect terminating existing swaps would be actually OK."
Debt advisory analyst, global debt advisory firm — weekly terminate-vs-roll NPV comparison on an infrastructure refinancing"This would really just be when clients are either looking at borrowing more money and wanting to restructure hedges or… blending and extending and all that kind of stuff… If a client did, you know, borrow more and then do another swap, we would usually look at… getting the bank to blend them."
Agricultural finance consultant, Australia — MtM on existing AUD (BBSW-linked) swaps ahead of blend-and-extend conversations"One thing that this has just sparked in my mind is swap breakage costs. Say we're fixing that 4.06% and we have two years remaining in the loan, a year down the line and the curve has shifted out by 100 [bps] — is there any functionality at the moment?"
Debt advisory associate, global real estate consultancy — asked, then shown the MtM-over-time forecast on the same call"Let's say we have a swap that was struck at XYZ rate and now we want to put some money in to the swap and buy down the rate. So we pay the banks an up[front] amount and we say, OK, can you lower the rate for us?… I can see here that you have the… basis point value… if we have the money that we want to inject in, we just divide that by this amount here… it would basically show us how much the fixed rate would move by."
Treasury lead, UK specialist mortgage lender — models rate buy-downs around RMBS closings and restructures"We're currently, we've posted collateral. But if we shift to daily margining, that's when this daily mark to market becomes very important for us." — and when asked why move to daily margining: "We want to get our money back."
Treasury team, UK consumer-electronics leasing fintech — validated BlueGamma's PV01 against their own MtM tool and the bank's statementsFAQs
Breakage is the swap's mark-to-market (MtM): the present value of the remaining fixed-leg cash flows against the floating leg, discounted off today's curve. If rates have fallen since you fixed, the swap is against you and you pay to break it; if rates have risen, the bank owes you. BlueGamma calculates this live for any amortising or custom notional profile.
The bank quotes breakage as mid MtM plus its own charge — unwind spread, credit and capital adjustments, and margin. Without an independent mid you can't see where the mid ends and the charge begins. An independent MtM within about a basis point of the bank's own mid makes that spread visible and negotiable.
Yes. The swap MtM tool shows a forecast of the mark-to-market over time: it holds today's curve steady and rolls the swap forward, so you can see the breakage amortise towards zero as each remaining interest payment drops away. That lets you weigh refinancing now against waiting a few payment dates — and it's exactly the question a real estate debt advisory team asked on their first demo.
Yes. Set the restructure up as its component swaps — one holding the existing off-market fixed rate for the near years (which creates a new mark), a second spreading that mark over the remaining years — and price each off the same live curve. A debt advisory firm executed exactly this two-phase restructure on a BlueGamma trial and matched the bank's pricing; a legacy market-data vendor could not produce a usable price for the same structure.
Compare the NPV of breaking today and re-hedging at market against keeping the legacy fixed rate — the answer depends on where your rate sits versus the current curve, not on instinct. Advisory teams run this as a weekly analysis while the refi is live, because the mark can swing by millions within days; one analyst's verdict after running it: "I didn't expect terminating existing swaps would be actually OK." If the existing hedge banks aren't part of the new financing, factor in novation or termination charges (execution plus credit) on top of the mid.
Weight each leg's fixed rate by its PV01 (risk), not just its notional. For example, an existing swap at 4.19% plus a top-up struck at 4.81% blends to roughly 4.36% depending on the relative sizes and remaining tenors. Load both swaps in BlueGamma, read the PV01 on each, and the blended rate is one weighted average away — the same maths the bank runs before quoting you a blend-and-extend.
Use the swap's basis point value (BPV / PV01). Divide the upfront amount by the BPV to see roughly how many basis points the fixed rate moves. BlueGamma shows the live BPV and the replacement rate — the new fixed rate if the full mark-to-market were paid down — on every swap you load.
It should sit within roughly a basis point of the bank's mid, provided payment dates, day counts and amortisation match the confirmation exactly. When it doesn't match, the gap is usually a trade-detail mismatch, not the curve: one advisor reconciling a pre-hedge traced a difference straight to a four-year vs five-year tenor assumption and mismatched interest dates. BlueGamma builds curves from the same broker and exchange data that the major terminals and the banks consume, and customers routinely validate the numbers against their bank statements and their own models during the trial — we encourage it.
No. A terminal gives you raw curves but you still assemble the valuation yourself, and shrinking extract caps make even that painful. And the legacy vendor has struggled with structured restructures in practice — one advisor found it "wasn't even close" on a two-phase off-market swap that priced correctly on BlueGamma. BlueGamma is purpose-built for this workflow at a fraction of terminal cost.
Yes. Load the swap once and the MtM recalculates live off curves refreshed every 30 seconds, with no download limits. Treasury teams that post collateral or move to daily margining use the daily mark-to-market to check the bank's margin calls — and, in one treasurer's words, because "we want to get our money back."
