情绪反转:美股暴力反弹与期权逼空的现货波动率双升动力
上周全球市场经历了一个非常令人兴奋的周期,主要股指出现暴力反弹(Crash Up),标普500指数甚至创下了历史新高。在此之前,市场表现其实相当疲软:各大指数在区间内震荡并失去上涨动能,作为AI交易先锋的超微电脑(CSP)在单月内暴跌40%,失去了领涨势头;受伊朗冲突引发的能源价格上涨推动,美债利率也持续走高。然而,在美联储会议后市场形势看似岌岌可危的几天内,指数却拔地而起。
这种上涨呈现出非常独特的现货与波动率双升(Spot Up Vol Up: 股价指数与隐含波动率同步上升的异常现象)动力特征。这种现象以往多见于单只个股(如SanDisk或AMC)的期权逼空(Gamma Squeeze),即投机者大量买入看涨期权,迫使做市商不得不买入标的资产进行对冲,进而推高股价。而这一次,这种逼空发生在了指数层面,主要是由于投机者因害怕错过上涨(FOMO)而疯狂加仓看涨期权。此外,正如衍生品专家吉姆·卡森(Jim Carson)所指出的,采用备兑看涨期权策略(Call Overriding: 卖出看涨期权以赚取收益的策略)的机构在指数大涨时被迫平仓止损,也进一步加剧了逼空行情。这种“现货与波动率双升”的结构极其不稳定,虽然在互联网泡沫时期曾持续数月,但往往预示着牛市已进入后期阶段,极易引发V型见顶。

Hello my friends. Today is August 8th and this is markets weekly. All right, so last week was actually a very exciting week in the markets. We had basically the major indexes crash up with the S&P 500 make new all-time highs. And in addition to that, we also had a joint US Japan currency intervention, something we haven't seen in decades. So first, let's talk about what could be leading the market to crash up. And secondly, let's talk about this yen intervention and why they did this and what else they could do because it doesn't seem like it's working all that well. All right, starting with the markets. So over the past few weeks, the market has looked to me pretty weak. Now the major indexes had been rangebound, so not making new highs, losing momentum. The AI trade had shown signs of crumbling with the CSP, the vanguard of the AI trade imploding 40% in one month and basically losing its mojo. And of course, looking at interest rates, they had been trading higher, driven in part by the higher energy prices from the Iran conflict. Now, despite all that and despite looking pretty dicey right after the Fed meeting, in a few short days, the indexes basically went straight up. In fact, you had this very interesting spot up vol up dynamic where you had the index prices going up and implied V going up as well. This is something that we often saw in single stocks where people or speculators would basically load up on calls and squeeze stocks like SanDisk or AMC higher and higher as market makers had to buy the underlying to hedge their exposure. But this time it was on the index level. It could be speculators just loading up on calls, fearing to miss the upside. Smart options people like Jim Carson Swan have also suggested that investors with call overriding strategies, so selling calls for income basically had to cover contributing to the squeeze. But in any case, these spot up dynamics are pretty unstable and can lead to these VTOPs and sometimes it can go on for weeks. during the dotcom boom. It went on for months, but it is in my personal view definitely something you see on the later cycles of a bull market. [snorts]
地缘缓和与就业迷局:降息预期的多重博弈与人口学真相
情绪扭转的第一个宏观驱动力是地缘政治紧张局势的缓和。有迹象表明,美国正寻求与伊朗达成某种“第二版谅解备忘录”。有国防部及军方高层向媒体披露,由于美国在中东冲突中消耗了大量防空拦截弹(Interceptor)库存,在库存告急且无法支撑全面冲突的现实下,政府内部主张外交缓和的声浪占据了上风。尽管伊朗可能因此在霍尔木兹海峡(Strait of Hormuz)的主导权博弈中获得更多筹码,甚至索要高额通行费,但冲突的降温直接消除了油价暴涨的风险,为市场移除了美债利率持续走高的地缘逆风。
另一个关键变量是扑朔迷离的非农就业报告(Non-farm Payrolls)。7月非农新增就业由市场预期的增加8万骤降至净减少2万。虽然这一新增数据极其低迷,引发市场对联储降息的预期急升,但另一个矛盾的数据是失业率(Unemployment Rate)却在同步走低。美联储官员近几个月强调,受婴儿潮一代老龄化退休、移民减少等结构性因素影响,目前评估就业市场已不能单看新增数量,甚至接近零的月度就业增长也能维持市场平衡。失业率的走低表明劳动力市场供需依然偏紧。虽然工资增长并未失控加速,且职位空缺率(Jolts)并未过热,使得这份报告显得十分矛盾,但所谓“衰退论者”(Doomers)认为“劳动力参与率下降是因为劳动者绝望退出市场”的说法并不成立。数据显示,排除因财富增长而提前退休的老人后,黄金年龄劳动力参与率(Prime-age Labor Force Participation: 25-54岁主力工作人群的劳动力参与比例)仍远高于疫情前水平,这表明当前劳动力市场只是健康回落而非系统性崩塌。

Now, what drove this sudden change in sentiment? I think there are a few pretty big things that happened. Well, first off, you have the evergreen idea was coming. A deal was close with Iran. Now the president backed off on his escalation and there's more and more noise that suggests that some kind of deal or memorandum of understanding version two was was happening. Now we have increasing reports that the US has basically spent is in a lot of its interceptor stockpile and so they really don't have the ammunition to go into any real conflict. Now, we already have many reports where the Iranians are shooting missiles on US bases and hitting targets and hurting people. Part of that is because there is just not that many interceptors left. Now, the way that, you know, government works, there's a ton of people in the government. Everyone has different views, motives, and before the war even began, we had people, very high level people in the military leaking to the press that this is going to be a disaster. And it seems like again uh you have people within the um institutions who realize that this is a disaster and this can't go on seemingly trying to make their case again leaking to the press that guys uh this is this is not good and uh that that seems to be working. It seems like within the administration there is more and more of an urge to get out uh realizing that there is no military solution. Now, the Iranians seem to be emboldened by this, realizing that they do indeed hold the cards and so reports suggest that they're asking for pretty hefty transit fees through the straight of Hormuz. And you know, at the the endgame is basically the US having to acknowledge in some form that the Iranians control the straight of Hormuz. That would be a very clear defeat. Uh but but it would end the conflict and you do seem oil prices kind of wavering a bit. So, but that is inevitably the direction that we're heading towards. And so, I think that in increased peace talk thing is uh is taking away a headwind from the markets and suggests that you know maybe interest rates won't have to keep trending higher and higher. Now, related to the interest rate front, we also had a very interesting non-farm spirals report. Now, the market was expecting maybe maybe 80,000 jobs created. Uh we actually had a loss of 20,000 jobs. though looking at the headline number that is a bad jobs report. The US is losing jobs and the knee-jerk reaction from the market was to price in uh less probability of rate hikes. So incrementally a more doubbish Fed. But that's just that's uh I think that might be a little bit too simple in interpretation of the jobs data because the other interesting Rinko is that the unemployment rate actually trended lower again. So we had the same thing happened last drops report whereas the unemployment rate trended lower. Now what the Fed has been talking about over the past few months is that we have these big demographic shifts in the labor market. You have say aging boomers less immigration and so forth. So they're not really sure what a good uh monthly jobs creation number is. uh they are leaning towards monthly job creation numbers of of zero being good enough for the economy given current trends in the labor market. So having a negative print here and there isn't out of the wouldn't be uh unexpected. So for them their emphasis has been the unemployment rate and the unemployment rate is unambiguously trending lower. Now that suggests that the labor market is actually tightening. So from that perspective, this would have actually been a hawkish drop print because it suggests that the labor market is is uh potentially overheating. Now one very strong push back against that is that wages haven't accelerated. If you were expecting the labor market to overheat, unemployment rate continue to trend lower, you would expect employers to bid up um labor costs and so accelerating wage growth. We're not seeing that. And you know, looking at other labor measures like the Jolts report, job openings per uh per employee, it's not really per person looking for work, it's not really heating up either. So, you know, it's not a super clear jobs report to me. Now, there will be people on the internet that say that this is a terrible job report and you have to discount the um declining unemployment rate because labor force participation is falling. People are just so desperate they can't find jobs and driving out dropping out of up the labor force. Now guys, doomers uh I want to be totally clear are almost always wrong and often low by Q people. So if you look at the labor force participation rate, it has dropped a lot. But we have to also be very thoughtful now. We have an aging population and you have a lot of boomers retiring in part because their stock market portfolios have exploded higher. So you would expect overall labor force participation to be declining as population ages and as there's less immigration flows. What you want to focus on if you have this narrative of people just desperate and dropping out of the labor force is prime age labor force participation. That is the labor force participation rate of people in their prime working years. And that participation rate has declined a bit over the past few months. But if you zoom out, you can see that it is comfortably above pre-andemic levels and historically within range. So I don't think that narrative is correct.
AI交易的演变:大科技龙头的领涨接力
推动美股情绪逆转的第三个动力在于AI交易的模式演变。虽然此前最拥挤的供应链瓶颈交易(如以超微电脑和内存芯片为代表的硬件环节)陷入了修整,但AI主线并未终结,而是转入了一场板块轮动。七巨头(Magnificent Seven: 微软、苹果、谷歌等大科技龙头)重新获得了上涨动力。诸如微软和亚马逊等超大市值权重的个股强势反弹,凭借其在各大核心股指中极高的权重,成功拉动整个大盘实现V型反转。AI交易的逻辑正在从单纯的硬件产能炒作,演变为对大科技巨头实际AI资本开支和应用变现能力的估值重塑。

Now the third thing that seems to be driving this revival in the stock market has to do with the AI trade. Now al although the bottleneck trades like the RAM trades uh are kind of languishing, you do have this rotation where the MAG 7 seems to be getting a second wind. You have these big stocks like Microsoft, like Amazon zooming higher and of course these have big weights in the major indexes and are able to carry them up. So the I trade not necessarily over but it seems to just have morphed a bit whereas memory is not going down and uh the the big tech guys are going up. So these themes just in a few short days have uh led to a manic reversal in the stock market and um well we we'll see what what happens.
美日汇率联合干预的台前幕后与息差逻辑
上周最震撼全球宏观市场的事件莫过于美日联合干预日元(Joint FX Intervention)。在此之前,由于日元兑美元跌至163的数提低点,日本财务省(Ministry of Finance: 日本负责汇率干预的行政部门)频繁入场“买日元、卖美元”进行干预。日元的大幅贬值推高了日本石油等进口商品的成本,导致国内通胀持续高于目标;然而,日本银行(Bank of Japan: 日本中央银行)因顾忌数十年通缩阴影或受政治制约,仅将利率维持在约1%左右,导致其实际利率长期处于负值区间,极大的利差直接成为日元贬值的基本面根源。
本次干预的独特之处在于,美国财政部罕见地与日本采取了联合行动。在具体操作层面,美国动用了由纽约联储(New York Fed)管理的平准投资组合,卖出手中约130亿美元的欧元,并买入日元。不仅如此,美国财政部还拥有外汇平准基金(ESF: Exchange Stabilization Fund: 财政部直接控制的外汇干预工具),该基金不仅包含220亿美元现金,还持有1750亿美元的特别提款权(SDRs: 国际货币基金组织创设的储备资产)。如果美国财政部选择将SDRs向美联储兑换成美元(这需要美联储印钞),并入场抛售美元购买日元,那将是极具杀伤力的干预弹药。然而,美国如此慷慨地帮助日元,在政治上主要是为了扶持日本这一关键的亚洲盟友(类似于此前对阿根廷总统米莱的援助),同时在金融层面上,稳定日元有助于防止日本国债(JGBs)长端收益率失控暴涨,从而减轻其对美国长端国债收益率的传导压力。

All right the second thing that I want to talk about is this very interesting episode of y intervention. So, as we know, over the past few months, the Ministry of Finance in Japan has been frantically trying to save the yen. The yen has been depreciating pretty significantly over the past couple years. Now, not too long ago, it was about 163 yen to the dollar at multi-deade lows. Uh, weakness, multi-deade highs in USD JPY, which is of course yen weakness. Now, this is a problem for Japan because Japan imports a lot of stuff. Now, it's super good for their importers because of course, uh, cheaper currency makes their profits look good in domestic currency terms, but they also import a lot of stuff like oil and that could potentially feed into inflation. Now, inflation for Japan has been above target. And yet, the Bank of Japan still has interest rates at about 1%. So, real interest rates, as they say, are negative. It's a very curious place to be in because well inflation is high, your currency is rapidly depreciating and yet your interest rates are quite low. Now there are people that suggest that uh the Bank of Japan uh is politically constrained because the prime minister doesn't want them to hike rates. Now the bank of Japan will probably say that they have been in deflation or disinflation for so many decades that they are cautious and don't want to um you know do anything that might uh push them back into their uh deflationing malaise that they were in for many decades now. Again, I'm I'm not in the room with their discussion, so I don't know what's actually true. But at the end of the day, the low interest rates in Japan are making it very difficult for the yen to strengthen. So, what the Bank of Japan and the Ministry of Finance have been doing has been intervening, basically uh buying yen, selling dollars to try to strengthen it. Now you notice that over the past few months this works only temporarily because the fundamentals of yen depreciation are just too strong. So what they what seems to be new this time is that they are getting the US to intervene with them. So a joint intervention to try to um strengthen the yen. Now this is something that the US hasn't really done with Japan for many many decades and it is also something that sends a much stronger signal to the markets because now it's not just Japan it's also the US and of course the US uh can print dollars. Now what actually happened is that the US sold euros and bought Japanese yen. Now the U United States has actually a foreign exchange portfolio. Uh it is managed by the New York Fed. Now in that they had about 13 billion euros and it seems like what Besson did was that he sold those euros and use it to buy yen and that was their contri contribution to strengthening the yen. Now I I was thinking that this is probably all they could do as uh being from the New York working out the open markets that is the portion of the portfolio that I'm most familiar with. But actually as many people on the internet pointed out there's actually more things that the US secretary could do. The ESF, the exchange stipulation fund, actually also holds 22 billion in US dollars and 175 billion in NSDRs. Now, the dollars they hold, that's that's cash they can readily deploy. The STR though is a little bit different and it requires an extra step. What they would do is actually have to do is they would actually have to exchange those STRs for dollars from the Fed. So, the Fed would actually have to print dollars for them. they could then take those dollars and sell them and buy yen. So, it's an extra step. Now, is the US Treasury going to do that for Japan? Just kind of end up at the end of the day with a ginormous portfolio of Japanese yen? I I I don't know. I'd guess no, cuz you know, why would you want so much yen? Although it is historically undervalued. So, many people are wondering why the US Treasury is doing this. Now I think there are new stories that suggest that the president is doing this because Takahuchichi is a good US ally. They want to basically uh do her a favor. Now this is something that the Trump administration has done before. Remember just last year they helped out President Milei in Argentina giving him uh some some dollars. So this is something that they've already done before. It's kind of like a favor to shore up a US ally. Now the doomers would say something like it's protect the US Treasury market and honestly that's I think that's really stupid. Um oh actually let me caveat that now smart people at JP Morgan have noticed that there is a relationship between a weak Japanese yen and upward trends in the long bond in Japan. So the long N JGBs. So and if the long JGB's rise in yield that also puts upward pressure on the long bond in the US. So being able to stabilize the Japanese yen stabilizes the Japanese long end and could of course provide some support for the US long bond. So so that is a potential thing.
FEMA回购的心理战与日元汇率的终极救赎
美国财政部建议日本动用美联储的海外和国际货币当局回购工具(FEMA Repo Facility: 允许外国央行抵押美国国债获取美元的便利工具),试图以此向市场展示充足的干预“弹药”以威慑做市商。然而,对于拥有美联储双边货币互换额度(FX Swap Lines)的日本而言,这在实操中是一个伪命题。日本已经拥有近乎无限且成本更低的互换美元额度。即使日本不想直接抛售美债以防冲击债市,它也可以在充裕的私人回购市场以低于FEMA的利率融入美元。更重要的是,通过分析纽约联储的海外回购资金池(Foreign Repo Pool: 外国央行存放于美联储的活期存款账户)数据可知,日本在该账户中拥有数千亿美元的存量资金,可以直接支取用于干预。
因此,宣传FEMA工具只是一种心理战术。然而,由于美日之间巨大的利差,本轮将汇率由163拉回至158的强力干预并未引发历史性的“套利交易清盘”(Carry Trade Unwind: 融入低息日元买入高息外币资产的套利盘平仓),市场甚至没有产生恐慌。这说明在利差基本面调整之前,任何不配合大幅加息的联合干预都只是在浪费外汇储备。

Um so one of the things that Secretary Besson uttered is that you know we want Japan to use the FEMA repo facility to be able to shore up. Now the whole point of this is to convey to the markets that we have a lot of ammo because if Japan could so in this uh storytelling in this story if Japan could access the FEMA repo facility they could they could which they do have access to to be clear uh and Secretary Besset wants to upsize it. If Japan could access an upsized female repo facility, what they could do is that they could pawn their treasuries for cash and they have a lot of treasuries, hundreds of billions of treasuries and then take those dollars and intervene in the currency markets. That would tell the market first off they have hundreds of billions of dollars they could deploy and secondly they could do that without selling treasuries so that uh it would not put upward pressure on the treasury. uh yields. So that that seems to be the story. Now that you know to my view is is just obviously nonsense because first off uh we have to think back what the female repo facility really is for. Now during the 2020 uh pandemic panic, you had the treasury market clog up because a lot of people were selling treasuries and to get dollars and that overwhelmed the plumbing of the system and cause the treasury market to crack. So the FIMO repo facility was a way to allow foreign sovereigns to get dollars with their treasury securities without actually selling them so as to not disrupt the treasury market. Now, this facility is really just targeted for um for central banks that don't have dollar swap lines. If you have a dollar swap line, you basically have unlimited access to dollars. For example, the Bank of Japan print yen, exchange that for dollars and they would have dollars and the F and the FX swap lines at times could have take up of up to half a trillion dollars during crisis. So it is basically a limited dollars to people who have access to a swap line with the New York Fed. But if you don't have access to a swap line, let's say you're China or someone like that, uh then you could then that becomes a problem. And so they created this FEMA repo facility so that countries in that situation could have access to dollars without selling their treasuries so as to not disrupt the treasury market. Okay. So fast forward to the context today. Japan has dollar swap lines. They have basically unlimited dollars that they could use uh to whatever way they they wanted to. Like some people say it's only for banks, but dude, it's an emergency facility. You could use it whatever you want. Um you think the US would say no to you when they're already obviously trying to help you intervene in your currency. So the Japan has basically unlimited dollars. Now secondly, do they want is it a concern about disrupting the treasury market? Well, if you are if you wanted to repo your treasuries without wanting to sell them, you actually had could do that very easily in the private sector. At the moment, the repo market it's it's not really congested. You have plenty of repo capacity and private sector repo rates are actually several basis points lower than what the Fed would charge you if you were to use the FEMA repo facility. So, it really doesn't make any sense. If the Ministry of Finance wanted to report out their treasuries, they could do that very easily and they don't really need the FEMA repo facility. And and honestly, it doesn't seem like dealer balance sheets are super clogged. So, if they were to sell them outright, I I don't think that it would actually have much impact on Treasury yields. But the last thing is, and this is something you would only know if you were, I think, super in the weeds, is that Japan actually has tons and tons of dollars stored in something called a foreign repo pool, which is basically a checking account at the New York Fed, a secured checking account at the New York Fed. Now, who exact? So, the New York Fed has a foreign repo pool. It's like a checking account for um foreign central banks. It's, you know, over 300 billion, fluctuates. Now who actually has an account like top secret okay you cannot know that but if you are familiar enough with the data you can tease out who it is from the publicly available data and this is not a secret from uh anyone who actually follows this very closely and there are very very very few people who do knows that it's actually mostly Japan that actually likes this facility and so they have a lot of liquidity in that bull that they could usually withdraw and deploy for intervention. So they don't really need a FEMA repo facility. So again, all of this in my perspective is just to create the impression that we have a lot of dollars. So don't you dare challenge us when we intervene. And yet if you look at the intervention, you can see that it's not super effective, right? It went from 163 all the way down to let's say 158. So this is surprising to me uh because if you think back a a couple years ago or actually look at the yen historically often times you would have bouts of severe strengthening and just several notches and you would have people who were in the yen carrier trade basically get carded out very disruptive but even though you had this monstrous intervention from Japan and even with US aid um not much happened. So this is telling me that the market is not really believing this because the interest rate differentials, they're just too large. The underlying fundamentals of a weaker yen are just too strong. So the only way you want to fix this is you need the Bank of Japan to start hiking more. And they're going to hike, but they they're going to have to hike at a more aggressive pace. So this looks like uh just kind of wasting dollars for both the US and for Japan until the underlying fundamentals are correcting. Uh I'm I'm actually super surprised that this hasn't had a kind of an riskoff effect. Um but uh I think that just tells you how convinced market participants are that the yen is weakening and they're not too scared. All right, so um that's all I prepared for today. Let's continue to watch how this yen trade developments. It's still possible that the US could, you know, go big, maybe even go to uh get their dollars from SDRs. I I do think that would be a big leap, though. It's kind of a big ask. It seems like the the easiest thing to do was just kind of shift their foreign currency portfolio a little bit, get rid of the euros, get some yen. So, it's more of a token thing. I think obviously everyone in Treasury understands it's a losing war unless you adjust interest rate differentials. All right, so that's how I prepared. Talk to you guys next week.
