Daniel sent us one from Jim today. Jim's an Australian expat living in Jerusalem, and he's looking at buying property here. The question is essentially: how do you think clearly about currency when you're making a purchase this size across multiple pairs? He wants to understand how to assess liquidity in a currency pair, how to find standardized volatility measures, how to identify support points in the rate, and what the geopolitical and macroeconomic forces are actually driving AUD/ILS and AUD/USD right now. Which, given that the shekel has been moving around quite a bit lately, is not a small question.
No, it really isn't. And by the way, today's script is courtesy of Claude Sonnet four point six, so if the analysis is unusually crisp, you know who to thank.
I'll reserve judgment. Jim's situation is actually a pretty sharp illustration of something that catches expats off guard. You think the hard part of buying property abroad is finding the property, negotiating the deal, navigating local bureaucracy. And those are all real. But the currency layer sits underneath all of it and it moves independently of everything else you're trying to control.
That's the part people underestimate. If you're an Australian converting Australian dollars into shekels to fund a Jerusalem property purchase, you're not just exposed to the Israeli property market. You're exposed to the AUD/ILS cross rate, which itself is basically a derived rate. There's no deep, liquid AUD/ILS market the way there's a deep AUD/USD market. So what Jim is actually navigating is a chain: Australian dollars to US dollars, US dollars to shekels, and all the volatility that lives in each of those legs.
The AUD/ILS rate as of right now is sitting around two point four five. It was two point six five in January. That's a meaningful move in about three and a half months. If Jim is looking at a property priced in shekels, that shift has already changed the Australian dollar cost of that purchase by something like eight percent before he's done a single thing wrong.
Right, and that's not a tail risk scenario. That's just what happened. The AUD/USD volatility index hit a five-year high in March, which rippled straight through into the cross rate. So the environment Jim is trying to make sense of is genuinely more turbulent than it's been for a while, and the tools he's asking about, liquidity assessment, volatility measures, support levels, macro and geopolitical drivers, those aren't academic. They're the actual framework for making a defensible decision here.
To put some numbers on that eight percent shift—if Jim is looking at a property priced at, say, three million shekels, that move from two point six five to two point four five has already added something in the range of eighty to ninety thousand Australian dollars to the effective cost of the purchase. That's not a rounding error. That's a renovation budget, or a significant chunk of stamp duty equivalent.
It happened in a period where Jim was probably doing other things. Talking to lawyers, getting financing sorted, visiting the property. The currency just moved underneath him while he was focused elsewhere. Which is exactly the dynamic that makes this worth getting into systematically rather than just checking the rate the morning of settlement.
Which is why this one is worth getting into properly. Liquidity is where we should begin, since it's the foundation everything else sits on.
Liquidity is the entry point, and it determines how reliable every other measure you look at is going to be. The basic intuition is: in a highly liquid pair, the price you see is the price you get, spreads are tight, and large transactions don't move the market against you. In a thin pair, all of that degrades. And AUD/ILS is thin.
When Jim is trying to assess a currency pair's liquidity, what's he actually looking at?
A few things. Bid-ask spread is the most direct signal. For AUD/USD you're typically looking at spreads under half a pip through any major broker. AUD/ILS, when you can even find a direct quote, the spread can be several times wider. Daily trading volume is the other metric, and for cross rates like this one, that data isn't always published cleanly, but the Bank for International Settlements triennial survey gives you a reasonable baseline. AUD/USD clears well over three hundred billion US dollars daily. AUD/ILS is a rounding error by comparison.
What does that spread difference actually mean in practice for someone converting a large sum? Because I think people hear "a few pips wider" and don't immediately translate that into dollars.
Right, so let's make it concrete. If Jim is converting the equivalent of, say, five hundred thousand Australian dollars, and the spread on AUD/ILS is four pips wider than it would be on a liquid pair, that's not four dollars. At that transaction size, you could easily be looking at several hundred to a few thousand dollars of additional cost just from the spread, before any market movement. And that's assuming the quote even holds while the transaction processes. In a thin market, you can get requoted mid-transaction because there wasn't enough depth to fill the order at the original price.
The thinness isn't just a theoretical problem. It has a direct cost attached to it.
A measurable one. And it's why most professional FX desks handling cross-rate conversions like this will route through the major pairs rather than trying to trade the cross directly. They'll sell AUD for USD, then sell USD for ILS, in two separate transactions, because the total cost of two liquid trades is lower than the cost of one illiquid one.
Which brings us to the four things Jim specifically wants to get his arms around. Liquidity is the first. Then volatility measurement, finding support levels in the rate, and understanding the macro and geopolitical drivers. They're not separate questions, really.
They're layered. Liquidity shapes how much weight you can put on the volatility data, because in a thin market, a single large transaction can create a spike that looks like volatility but isn't. Support levels are only meaningful if there's enough market participation to actually defend them. And the macro and geopolitical factors are what move the rate through those structural constraints.
The framework Jim needs isn't just a checklist. It's more like a sequence. You understand the market structure first, then you read the volatility correctly, then the technical levels mean something, and then the macro story tells you where it's all heading.
That's exactly the right order to think about it.
Jim's second question, and probably the one where most people reach for the wrong tool.
The instinct is usually to just look at a price chart and eyeball how much the rate has been moving. Which is fine as a starting point, but it's not a measure, it's a vibe. The standardized approach is historical volatility, which is the annualized standard deviation of log returns over a defined lookback period. Typically you'd look at twenty-day or sixty-day historical volatility to get a sense of short-term and medium-term realized movement. For AUD/USD right now, after that March spike, the numbers are elevated.
Then there's implied volatility, which is a different animal.
Right, implied volatility is forward-looking. It's derived from options prices. If the market is pricing AUD/USD options at a high premium, that's telling you traders expect significant movement, regardless of what's happened historically. The two measures together give you something useful: historical volatility tells you what the pair has done, implied tells you what the market thinks it's about to do. When they diverge sharply, that gap itself is informative.
If implied is running well above historical, the market is pricing in something it doesn't think is fully captured in recent price action.
And for Jim's purposes, that's a risk signal. It means the options market sees something coming that the recent chart doesn't fully show. The practical source for this is the Chicago Mercantile Exchange, which publishes implied volatility data for AUD/USD options. For AUD/ILS you won't find clean implied volatility data because the options market is too thin. You're back to deriving it from components.
Which is the same problem as the liquidity question. The thinness of the cross rate degrades every measure downstream.
And the 2023 commodity cycle is a decent illustration of this. During the iron ore and copper rally in mid-2023, AUD/USD liquidity actually deepened noticeably because the Australian dollar is heavily correlated with commodity prices, particularly Chinese demand for raw materials. Spreads tightened, volume rose, and the volatility readings became more reliable because there was genuine two-way flow. The lesson for Jim is that AUD liquidity isn't static. It tracks the commodity cycle, and right now that cycle is in a different phase.
The quality of your volatility data depends on what the commodity market is doing. That's not obvious.
It's one of the things that makes the Australian dollar interesting as a currency. It behaves partly like a commodity currency and partly like a developed-market safe haven depending on the environment. Which means your volatility baseline shifts with global risk appetite in ways that a purely trade-weighted analysis wouldn't predict.
There's actually a fun wrinkle in the AUD story that I think is worth mentioning here, which is that the Australian dollar has historically been called the "commodity dollar" alongside the Canadian dollar and the New Zealand dollar, and traders sometimes group them together as a bloc. But the AUD's correlation with iron ore specifically is unusually tight, because Australia's export mix is so concentrated. Canada has oil, New Zealand has agricultural products, but Australia's single largest export by value is iron ore by a significant margin. So when you're reading AUD volatility, you're also reading a proxy for Chinese steel production expectations. Which is a very specific thing to be tracking if you're an expat trying to buy a house.
It means that a headline about Chinese property sector weakness—which has been a recurring story—can move Jim's purchasing power in shekels before he's even thought about the Israeli side of the equation. The transmission mechanism is: Chinese property slows, steel demand falls, iron ore price drops, AUD weakens, Jim's conversion costs more. All of that can happen in a week.
Alright, support levels. Third item on Jim's list, and probably the most technically involved.
Support in a currency pair is a price zone where buying pressure has historically been strong enough to halt a downward move. The practical way to identify it is to look at the daily chart over a meaningful window, twelve to twenty-four months, and find the price levels where the rate has repeatedly reversed. For AUD/ILS, the two point four range has acted as a floor multiple times going back to late 2024. Whether it holds is a separate question, but the level is meaningful because enough market participants are watching it.
The caveat on thin markets applies here too. A support level in a liquid pair has real weight because there's genuine order flow defending it. In a thin cross rate, you can blow through a support level on relatively light volume.
Which is why Jim should treat AUD/ILS technical levels as indicative rather than reliable. The real technical work should happen on AUD/USD and USD/ILS separately, then synthesize the picture. Those are the legs with actual market depth. And that's before you even factor in the geopolitical layer.
How does that synthesis actually work in practice? Because saying "look at the two legs separately and then combine them" sounds straightforward, but I imagine there are moments where the two legs are moving in opposite directions and the net picture is ambiguous.
The way to think about it is that you're running two separate technical analyses and then stress-testing the cross against combinations. So if AUD/USD has strong support at, say, zero point six two, and USD/ILS has support at three point seven, then the implied AUD/ILS support is around two point two nine. But if AUD/USD breaks its support while USD/ILS holds, you're in a different scenario than if both break simultaneously. The cross rate can look stable on its own chart while both underlying legs are under pressure that hasn't fully resolved yet. That's the trap. You look at AUD/ILS, see it holding around two point four, and think it's fine—but the components are both wobbling and the cross is just slow to reflect it.
The cross rate chart can actually lag the real stress. That's a meaningful thing to know.
It's one of the more counterintuitive aspects of trading derived rates. The cross is always the last place the information shows up, because the market is pricing the components first.
Right, the geopolitical layer. That's where Jim's situation gets complicated, because he's not just tracking commodity cycles and Federal Reserve minutes. He's buying property in Jerusalem.
The shekel has its own story that runs parallel to everything happening with the Australian dollar. The ILS is not a commodity currency. It's not a petrodollar. It's a currency that reflects, more than almost any other in the developed world, a specific confluence of tech sector performance, central bank credibility, and geopolitical risk premium.
The tech angle is underappreciated. When people think about what moves the shekel, they go straight to security situations and regional tensions. But the Bank of Israel has been pretty explicit that the tech sector's foreign currency inflows are a significant structural support for the currency. When Israeli tech companies raise international rounds or get acquired, those transactions convert into shekels. That's real demand.
It's substantial. Israel's tech exports were running at something like twenty-two percent of total exports in recent years, and that share has grown. So when the sector has a good period, you see shekel strength that isn't obviously explained by trade balances or rate differentials. The shekel's strength reflects genuine fundamentals, not just a safe-haven reflex.
Which means Jim needs to watch two things simultaneously. The health of the Israeli tech sector as a shekel-positive force, and the geopolitical risk premium as a shekel-negative force. And those two things don't always move together in predictable ways.
They can offset each other for extended periods, and then one of them dominates suddenly. In the months after October 2023, you saw the risk premium spike sharply, but the shekel recovered faster than most analysts predicted, partly because the tech sector's underlying activity didn't collapse the way some feared. The currency market was essentially betting that the structural tech story would outlast the security disruption, and that bet paid off.
For Jim, the implication is that a period of elevated regional tension isn't automatically a reason to wait. If the tech fundamentals are intact and the risk premium is already priced in, the rate might not move much further against him.
Or it might. That's the honest answer. But the framework is right. You don't just look at headlines. You look at whether the risk premium is already embedded in the spot rate, and whether the structural supports are still functioning.
Now the other half of this is what's happening with the Australian dollar. And the dominant story there right now is US monetary policy.
The Federal Reserve rate decision earlier this year was a real inflection point for AUD/USD. When the Fed moved, it widened the rate differential between US dollar assets and Australian dollar assets, which put downward pressure on the AUD. The Reserve Bank of Australia has been navigating a different inflation trajectory than the Fed, and that divergence in rate paths is one of the cleaner explanations for why the AUD has been soft against the dollar this year.
That directly feeds into the AUD/ILS number Jim is watching. If the Australian dollar weakens against the USD, and the shekel holds or strengthens against the USD, the AUD/ILS cross gets hit from both sides simultaneously.
Which is exactly what the move from two point six five to two point four five reflects. It's not one thing. It's the Fed's rate path compressing AUD, and the shekel holding up reasonably well on its own fundamentals, and those two forces compounding in the cross rate. Neither of those forces is obviously about to reverse in the near term.
Jim's timing question isn't just about watching a chart. He needs a view on whether the Fed is done, whether the RBA responds, and whether the shekel's tech-sector support holds.
Trade balances matter here too. Australia's trade position is heavily influenced by Chinese demand for iron ore and LNG. If Chinese industrial activity softens, Australian export revenue falls, the current account weakens, and the AUD comes under additional pressure. That's a separate channel from interest rate differentials, but it can move in the same direction at the same time.
Three forces all potentially pushing the same way. Fed rate differential, China demand, and shekel structural strength. That's a real headwind for an Australian buyer converting into shekels right now.
It's not a reason not to buy. But it's a reason to have a view, or at least a hedging strategy, rather than just converting at spot on the day of settlement and hoping for the best. And that's where Jim's approach comes into play.
Right, but what does Jim actually do with all of that? Because there's a real risk that a framework this thorough becomes a reason to never pull the trigger.
The first practical step is separating the monitoring problem from the decision problem. For monitoring, the tools are straightforward. TradingView gives you historical volatility overlays for AUD/USD, you can set custom lookback windows, twenty-day, sixty-day, and watch how realized volatility is trending relative to that March spike. For implied volatility on AUD/USD specifically, the CME's options data is publicly accessible. Those two numbers together tell you whether the market thinks the turbulence is settling or building.
For the ILS leg?
Bank of Israel publishes daily reference rates and has historical data going back years. That's your cleanest source for AUD/ILS tracking, even though the rate is derived. For USD/ILS, Bloomberg and Reuters both carry it with decent depth. The practical workflow is to monitor AUD/USD and USD/ILS separately, then check the cross. When both legs are moving against Jim simultaneously, that's the signal to pause. When they're offsetting each other, the net exposure is smaller than it looks.
Given where things actually stand.
The honest framing is that the move from two point six five to two point four five has already happened. Jim is looking at a rate that's already absorbed a significant deterioration. The question is whether the forces driving that move are exhausted or still running. Fed policy is the swing factor. If the rate differential stabilizes, AUD/USD stabilizes, and the cross stops bleeding. That's worth watching before committing to a settlement date.
The practical advice is: don't convert at spot on the day of settlement. Use a forward contract to lock a rate once you have a transaction timeline, and keep monitoring the Fed calendar and Bank of Israel communications in the weeks before.
Forward contracts are underused by individual buyers in this situation. The cost of locking in is usually modest relative to the risk of a five percent move in the two weeks around settlement.
How modest are we talking? Because I think some people assume forward contracts are complicated financial instruments that require a broker relationship and a lot of paperwork.
For retail buyers doing cross-border property transactions, the mechanics are actually pretty accessible. Most specialist FX providers—companies that exist specifically to handle large international transfers—offer forward contracts as a standard product. You agree on a rate today, pay a small deposit, and the provider holds that rate for you until your settlement date, which could be thirty, sixty, or ninety days out. The cost is typically built into a slightly less favorable rate than the absolute spot, but that margin is usually well under one percent. Compare that to the risk of a five percent adverse move in six weeks, and the math is straightforward.
There are providers that specialize specifically in property transactions for expats. It's not like Jim has to walk into a bank and explain cross-rate exposure to someone whose job is normally handling holiday money.
Right, the specialist providers understand the use case. They're set up for exactly this situation: someone has a settlement date, a known shekel amount, and needs certainty on what it costs in Australian dollars. That's a standard transaction for them even if it feels exotic to the buyer.
That five percent move in two weeks isn't just theoretical—it's real money on the line, especially for something like a Jerusalem property purchase.
It's the kind of thing that feels obvious in retrospect and gets ignored in the moment because everyone is focused on the transaction itself, not the settlement mechanics.
The open question Jim is left with, and honestly anyone doing cross-currency property math right now, is what the Fed does next. Because that's the variable with the most leverage on his specific situation. If the rate differential between US dollar assets and Australian dollar assets starts to compress, you'd expect AUD to recover some ground, and the cross rate improves for him. But if the Fed holds longer than the market currently expects, the pressure on AUD doesn't release.
On the shekel side, the question is whether the tech sector's inflow story holds at current valuations. That's not a geopolitical question. It's a venture capital and M&A cycle question, which is harder to track but arguably just as consequential for the rate.
The geopolitical risks don't stop at the obvious ones. Regional tension, Fed policy, Chinese iron ore demand, Israeli tech M&A activity. Jim's hedging problem is actually four separate risk factors that can all move simultaneously and in the same direction.
Which is why the forward contract isn't optional. It's the only tool that takes the settlement timing risk off the table entirely, whatever else is happening in the world.
If Jim wants to go one step further, there's a case for splitting the conversion. Lock in a forward for a portion of the total—say, seventy percent—and leave thirty percent at spot. That way he's protected against the worst case on most of the exposure, but he still participates if the rate happens to improve before settlement. It's not a sophisticated strategy, but it's a reasonable way to manage the psychological tension between wanting certainty and not wanting to lock in at the wrong moment.
That split approach is actually quite common among buyers who have done this before. The first time, people either do nothing and get lucky or get hurt. The second time, they lock everything in and feel good about it. By the third time, they've usually landed on some version of the partial hedge because they've seen both failure modes.
Good luck, Jim.. It's a complicated set of variables to hold in your head while also trying to buy a house.
The framework is sound. That's what matters. And honestly, the fact that he's asking these questions before settlement rather than after is most of the battle. Most of the pain in these situations comes from people who didn't know there was a question to ask.
